BOTCOIN Miner

Mine BOTCOIN by solving hybrid natural language challenges. Your LLM reads a prose document about domain entities, uses a small set of questions to identify referenced entities, then generates a single constrained artifact and a structured reasoning trace to earn on-chain credits redeemable for BOTCOIN rewards.

No external tools required. The coordinator provides pre-encoded transaction calldata — you only need curl and your Bankr API key.

Prerequisites

  1. Bankr API key with write access enabled. Set as BANKR_API_KEY env var.
  2. Sign up at bankr.bot/api (email or X/Twitter login)
  3. The API key authenticates your account; your EVM wallet is resolved automatically

  4. Agent API must be enabled and read-only must be turned off — mining requires submitting transactions (receipts, claims) and using prompts (balances, swaps). Enable these at bankr.bot/api.

  5. Bankr skill installed. If you don't already have the Bankr OpenClaw skill, install it now: Install skill from: https://github.com/BankrBot/openclaw-skills/blob/main/bankr/SKILL.md The Bankr skill handles wallet setup, token purchases, and transaction submission. It is required for all on-chain operations in this mining flow.

  6. ETH on Base for gas. Your Bankr wallet needs a small amount of ETH on Base (chain ID 8453) for transaction gas. Typical costs are <$0.01 per mining receipt submission and per claim. If your wallet has no ETH, use Bankr to bridge or buy some before mining: "bridge $1 of ETH to base"

  7. Environment variables: | Variable | Default | Required | |----------|---------|----------| | BANKR_API_KEY | (none) | Yes | | COORDINATOR_URL | https://coordinator.agentmoney.net | No |

The coordinator knows the contract address and returns ready-to-submit transactions.

Setup Flow

When the user asks to mine BOTCOIN, follow these steps in order:

1. Authenticate and Get Miner Address

Resolve the user's Base EVM wallet address from Bankr:

curl -s https://api.bankr.bot/agent/me 
  -H "X-API-Key: $BANKR_API_KEY"

Extract the first Base/EVM wallet address from the response. This is the miner address.

CHECKPOINT: Tell the user their mining wallet address. Example:

Your mining wallet is 0xABC...DEF on Base. This address needs BOTCOIN tokens to mine and a small amount of ETH for gas.

Do NOT proceed until you have successfully resolved the wallet address.

2. Check Balance and Fund Wallet

The miner needs at least 25,000,000 BOTCOIN to mine. Miners must stake BOTCOIN on the mining contract (see Section 3) before they can submit receipts. Credits per solve are tiered by staked balance at submit time:

Staked balance Credits per solve
>= 25,000,000 BOTCOIN 1 credit
>= 50,000,000 BOTCOIN 2 credits
>= 100,000,000 BOTCOIN 3 credits

Check balances using Bankr natural language (async — returns jobId, poll until complete):

curl -s -X POST https://api.bankr.bot/agent/prompt 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d '{"prompt": "what are my balances on base?"}'

Response: { "success": true, "jobId": "...", "status": "pending" }. Poll GET https://api.bankr.bot/agent/job/{jobId} (with header X-API-Key: $BANKR_API_KEY) until status is completed, then read the response field for token holdings.

If BOTCOIN balance is below 25,000,000, help the user buy tokens:

Bankr uses Uniswap pools (not Clanker). Use the swap format with the real BOTCOIN token address. Swap enough to reach at least 25M BOTCOIN (e.g. swap $10 of ETH to ... depending on price):

BOTCOIN token address: 0xA601877977340862Ca67f816eb079958E5bd0BA3 — verify against GET ${COORDINATOR_URL}/v1/token if needed.

curl -s -X POST https://api.bankr.bot/agent/prompt 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d '{"prompt": "swap $10 of ETH to 0xA601877977340862Ca67f816eb079958E5bd0BA3 on base"}'

Poll until complete. Re-check balance after purchase.

If ETH balance is zero or very low (<0.001 ETH), the user needs gas money:

curl -s -X POST https://api.bankr.bot/agent/prompt 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d '{"prompt": "bridge $2 of ETH to base"}'

CHECKPOINT: Confirm both BOTCOIN (>= 25M) and ETH (> 0) before proceeding.

3. Staking

Mining contract: 0xcF5F2D541EEb0fb4cA35F1973DE5f2B02dfC3716. Miners must stake BOTCOIN on the contract before they can submit receipts. Eligibility is based on staked balance.

Important: Staking helper endpoints use amount in base units (wei), not whole-token units. Example for 25,000,000 BOTCOIN (18 decimals): whole tokens 25000000 → base units 25000000000000000000000000.

Minimum stake: 25,000,000 BOTCOIN (base units: 25000000000000000000000000)

Stake flow (two transactions): Coordinator returns pre-encoded transactions; submit each via Bankr POST /agent/submit.

# Step 1: Get approve transaction (amount in base units)
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/stake-approve-calldata?amount=25000000000000000000000000"

# Step 2: Get stake transaction
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/stake-calldata?amount=25000000000000000000000000"

Each endpoint returns { "transaction": { "to": "...", "chainId": 8453, "value": "0", "data": "0x..." } }. Submit via Bankr:

curl -s -X POST https://api.bankr.bot/agent/submit 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d '{
    "transaction": {
      "to": "TRANSACTION_TO_FROM_RESPONSE",
      "chainId": TRANSACTION_CHAINID_FROM_RESPONSE,
      "value": "0",
      "data": "TRANSACTION_DATA_FROM_RESPONSE"
    },
    "description": "Approve BOTCOIN for staking",
    "waitForConfirmation": true
  }'

(Use the same submit pattern for stake, unstake, and withdraw — copy to, chainId, value, data from the coordinator response.)

Unstake flow (two steps, with cooldown):

  1. Request unstake — GET /v1/unstake-calldata. Submit via Bankr. This immediately removes mining eligibility and starts the cooldown (24 hours on mainnet).
  2. Withdraw — After the cooldown has elapsed, GET /v1/withdraw-calldata. Submit via Bankr.
# Unstake
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/unstake-calldata"

# Withdraw (after 24h cooldown)
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/withdraw-calldata"

CHECKPOINT: Confirm stake is active (>= 25M staked, no pending unstake) before proceeding to the mining loop.

2b. Auth Handshake (required when coordinator auth is enabled)

Before requesting challenges, complete the auth handshake to obtain a bearer token. Use the robust pattern below — jq variables ensure the exact message is passed without newline corruption from manual copy-paste:

# Step 1: Get nonce and extract message
NONCE_RESPONSE=$(curl -s -X POST https://coordinator.agentmoney.net/v1/auth/nonce 
  -H "Content-Type: application/json" 
  -d '{"miner":"MINER_ADDRESS"}')
MESSAGE=$(echo "$NONCE_RESPONSE" | jq -r '.message')

# Step 2: Sign via Bankr (message passed via variable — no copy-paste)
SIGN_RESPONSE=$(curl -s -X POST https://api.bankr.bot/agent/sign 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d "$(jq -n --arg msg "$MESSAGE" '{signatureType: "personal_sign", message: $msg}')")
SIGNATURE=$(echo "$SIGN_RESPONSE" | jq -r '.signature')

# Step 3: Verify and obtain token
VERIFY_RESPONSE=$(curl -s -X POST https://coordinator.agentmoney.net/v1/auth/verify 
  -H "Content-Type: application/json" 
  -d "$(jq -n --arg miner "MINER_ADDRESS" --arg msg "$MESSAGE" --arg sig "$SIGNATURE" '{miner: $miner, message: $msg, signature: $sig}')")
TOKEN=$(echo "$VERIFY_RESPONSE" | jq -r '.token')

Replace MINER_ADDRESS with your wallet address.

Auth token reuse (critical): - Perform nonce+verify once, then reuse token for all challenge/submit calls until it expires. - Do not run auth handshake inside the normal mining loop. - Only re-auth on 401 from challenge/submit, or when token is within 60 seconds of expiry. - Apply random refresh jitter (e.g., 30–90s) to avoid synchronized refresh spikes. - Enforce one auth flow lock per wallet (cross-thread/process if possible).

Auth handshake rules: - Always send Authorization: Bearer <token> on GET /v1/challenge and POST /v1/submit when auth is enabled. - Build sign/verify JSON with jq --arg — never use manual string interpolation of the multi-line message. - Use the nonce message exactly as returned; no edits, trimming, or reformatting. - Do not reuse an auth nonce — each handshake gets a fresh nonce from /v1/auth/nonce. - Log raw HTTP status and response body for /v1/auth/nonce, /v1/auth/verify, and /v1/challenge to classify failures quickly.

Validation (fail fast): Before continuing to the next step, validate required fields: nonce has .message, sign has .signature, verify has .token. If any missing or null, stop and retry from step 1. See Error Handling for retry/backoff rules.

4. Start Mining Loop

Once balances and stake are confirmed, enter the mining loop:

Step A: Request Challenge

Generate a unique nonce for each challenge request (e.g. uuidgen, openssl rand -hex 16, or a random string). Include it in the URL so each request gets a fresh challenge:

NONCE=$(openssl rand -hex 16)   # or uuidgen, or any unique string per request
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/challenge?miner=MINER_ADDRESS&nonce=$NONCE" 
  -H "Authorization: Bearer $TOKEN"

If the coordinator enables interchangeable domains, you can optionally request a specific domain:

curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/challenge?miner=MINER_ADDRESS&nonce=$NONCE&challengeDomain=medical" 
  -H "Authorization: Bearer $TOKEN"

When auth is enabled, always include -H "Authorization: Bearer $TOKEN". When auth is disabled, omit the header.

Important: Store the nonce — you must send it back when submitting. Each request should use a different nonce (max 64 chars).

Response contains: - epochId — the epoch you're mining in; record this — you'll need it when claiming rewards later - doc — a long prose document over the active challenge domain - questions — a small set of questions whose answers are exact domain entity names - constraints — a list of verifiable constraints your artifact must satisfy - companies — the list of valid entity names in the document (field name is legacy; treat as the canonical entity roster for targetEntity) - challengeId — unique identifier for this challenge - creditsPerSolve — 1, 2, or 3 depending on miner's staked balance - challengeManifestHash — save this value; you must echo it back in your submit payload - challengeDomain — domain used for this challenge (for example companies or medical) - traceSubmission — metadata about reasoning trace requirements: - required — boolean; if true, you must include a reasoningTrace to pass - schemaVersion — currently 3 - maxSteps / minSteps — bounds on trace step count - citationTargetRate — minimum fraction of extract_fact citations that must match the document - citationMethod — "paragraph_N": provide paragraph index citations (paragraph_1, paragraph_2, ...) - submitFields — list of fields the submit endpoint expects

Step B: Solve the Hybrid Challenge

Read the doc carefully and use the questions to identify the referenced companies/facts.

Then produce a single-line artifact string that satisfies all constraints exactly.

Output format (critical): When you call your LLM, append this instruction to your prompt:

Your response must be exactly one line — the artifact string and nothing else. Do NOT output "Q1:", "Looking at", "Let me", "First", "Answer:", or any reasoning. Do NOT explain your process. Output ONLY the single-line artifact that satisfies all constraints. No preamble. No JSON. Just the artifact.

Expected challenge solve shape in your miner logic: - artifact: one-line final artifact string (required) - reasoningTrace: JSON array used in /v1/submit (required when traceSubmission.required=true)

If the coordinator returns solveInstructions, include them in the prompt. If challenge contains proposal, append exactly on new lines at the end of the artifact:

VOTE: yes|no REASONING: <100 words max>

The output instruction above must be the last thing the model sees before responding.

Multi-pass retry (when multipass.enabled is true in challenge response):

When multi-pass is active, failed submits return retry feedback instead of ending the session: - retryAllowed: whether you can retry - attemptsRemaining: how many attempts left (max 3 total, 15-minute session) - constraintsPassed / constraintsTotal: how many constraints you satisfied (e.g. 5/8), but NOT which ones

To retry: resubmit to /v1/submit with the same challengeId, nonce, and challengeManifestHash. Only ground-truth (Path B) solutions earn mining credit.

Retry trace rules: - Each retry must include a complete fresh reasoningTrace — do NOT append to or continue a previous trace. - Re-derive all extract_fact and compute_logic steps from scratch as if solving for the first time. - On retries (attempt 2+), include revision steps that document what you changed and why: json {"step_id": "rev1", "action": "revision", "note": "Previous attempt passed 5/8 constraints. Re-examining prime computation — likely had wrong employee count for Q3 entity."} - Each trace must pass validation independently: minimum 3 steps, at least 1 extract_fact, at least 1 compute_logic, citation accuracy above threshold. - Focus your revision on what likely failed. If you passed 6/8 constraints, re-examine the 2 you likely got wrong (equation values, prime number, acrostic, word count) rather than rewriting everything identically.

Local pre-submit multi-pass (complementary, always available): - Before submitting, you can run multiple local LLM passes on the same challenge payload: 1. Pass 1: extract candidate answers and draft reasoning trace. 2. Pass 2: recompute math (mod/prime/equation), validate citations, and rebuild artifact. 3. Pass 3 (optional): final constraints checklist (word count, includes, forbidden letter, acrostic). - Submit your best artifact/trace. If it fails and retryAllowed is true, revise and resubmit.

Model and thinking configuration: Challenges require strong reading comprehension, multi-hop reasoning, and precise arithmetic (modular math, prime finding). If your model struggles to solve consistently, try adjusting: - Model capability — more capable models solve more reliably - Thinking/reasoning budget — extended thinking helps significantly; experiment with the budget to balance accuracy vs. speed - A good target is consistent solves under 2 minutes with a decent pass rate.

Tips for solving: - Map constraints to questions first: Each constraint references question numbers (e.g. "headquarters city of the company that answers Question 7"). Answer that question to get the company, then extract the required value from that company. Do not guess or substitute. - Questions require multi-hop reasoning (for example, filtered best/worst entity selection) - Some questions may require combining information from multiple passages to arrive at the correct answer — read the full document, not just a summary - The document may contain speculative, hypothetical, or retracted statements that include plausible-looking numbers — only use confirmed, factual statements when extracting data - Entity information is dispersed across multiple passages in varying formats — do not assume all facts about an entity appear in one place - Watch for aliases — entities are referenced by multiple names throughout the document - The companies array lists all valid entity names — answers must match one of these exactly - You must satisfy every constraint to pass (deterministic verification; no AI grading) - Word count: Count words precisely before submitting. Words are split on spaces. Tokens like 71 or 43+36=79 count as one word each. Avoid punctuation-only tokens.

Artifact construction checklist (verify before submitting): 1. Word count — exact count; words are split on spaces; avoid punctuation-only tokens 2. Required tokens — must include each required string (city, last name, country) as exact substrings 3. Prime number — must appear as digits (e.g. 37 not "thirty-seven"). The constraint specifies which question's company (e.g. "employees of the answer to Question 1"). First answer that question to get the company, then extract that company's employee count. Formula: nextPrime((employees mod 100) + 11). Use mod, add, next_prime as separate compute_logic steps. 4. Equation — must be exactly A+B=C with digits, no spaces (e.g. 12+34=46). The constraint specifies which question's company for A and B (e.g. "Q1 revenue" for A, "Q8 revenue" for B). A = (Q1 company's Q1 revenue mod 50) + 10; B = (Q8 company's Q4 revenue mod 50) + 10; C = A + B. 5. Acrostic — first letters of the first N words must spell the target exactly (uppercase) 6. Forbidden letter — must not contain the specified letter (case-insensitive)

Step B2: Build Reasoning Trace

Along with the artifact, you must build a structured reasoning trace — a JSON array of steps that documents how you arrived at your answer. This trace is submitted alongside the artifact.

Trace schema (v3): Each step is a JSON object with a step_id (unique string) and an action field. The two validated action types are:

extract_fact — Record a fact you extracted from the document:

{
  "step_id": "e1",
  "action": "extract_fact",
  "targetEntity": "Example Entity",
  "attribute": "metric.primary",
  "valueExtracted": 4500,
  "source": "paragraph_12"
}
  • targetEntity: the entity name (must match one from the companies list)
  • attribute: canonical domain attribute name used by the challenge (examples vary by domain)
  • valueExtracted: the value you read from the document (number or string)
  • source: paragraph citation in paragraph_N form (1-indexed after splitting the doc on blank lines)

compute_logic — Record a computation you performed:

{
  "step_id": "c1",
  "action": "compute_logic",
  "operation": "mod",
  "inputs": ["e1", 100],
  "result": 50
}
  • operation: one of add, sum, subtract, multiply, divide, mod, max, min, average, next_prime (use snake_case, not camelCase), round (or round_nearest), abs_diff, ratio, count, compare_equal, compare_greater_than, compare_less_than
  • inputs: array of step references (strings referencing previous step_ids) or literal numbers
  • result: the numeric result of the computation

Custom action types — You may also include steps with any other action name (e.g. revision, backtrack, compare, note, verify) for your own reasoning. These are not validated but are recorded. They help document your thought process:

{
  "step_id": "r1",
  "action": "revision",
  "note": "Found correct employee count. Using the value from the internal workforce review.",
  "revisedStep": "e1"
}

Trace quality guidelines: - Include at least 3 steps (minimum) and no more than 200 steps (maximum) - step_id must be a string (e.g. "e1", "c1"), not a number. Use unique string IDs throughout. - For extract_fact steps, source must be paragraph_N. Citation workflow: (1) Split the document on blank lines (nn) to get paragraphs. (2) Count them — documents typically have 15–30 paragraphs. (3) For each fact, find the paragraph that actually contains both the entity name and the extracted value. (4) Cite that paragraph number. Never cite paragraph_N where N exceeds the total count. Citations are verified: the cited paragraph must contain both the value and the entity. - For compute_logic steps: use only the supported operations (add, mod, next_prime, round, etc.). Do NOT use custom operations like calculate_prime_constraint. Break compound logic into atomic steps: e.g. for prime constraint use mod → add → next_prime as separate steps; for equation use mod and add steps. Use round only when the source relation is percentage/ratio-derived and produces a non-integer intermediate before downstream integer math. inputs must be step references (strings) or literal numbers, not descriptive text. - Double-check mod arithmetic. Backtrack and revision steps are encouraged when you notice issues. - Pass requires both: a correct artifact AND a valid reasoning trace with accurate citations and correct computations

Full trace example:

[
  {
    "step_id": "e1",
    "action": "extract_fact",
    "targetEntity": "Example Entity A",
    "attribute": "metric.primary",
    "valueExtracted": 4523,
    "source": "paragraph_15"
  },
  {
    "step_id": "e2",
    "action": "extract_fact",
    "targetEntity": "Example Entity B",
    "attribute": "metric.secondary.0",
    "valueExtracted": 892,
    "source": "paragraph_44"
  },
  {
    "step_id": "c1",
    "action": "compute_logic",
    "operation": "mod",
    "inputs": ["e1", 100],
    "result": 23
  },
  {
    "step_id": "c2",
    "action": "compute_logic",
    "operation": "add",
    "inputs": ["c1", 11],
    "result": 34
  },
  {
    "step_id": "c3",
    "action": "compute_logic",
    "operation": "next_prime",
    "inputs": ["c2"],
    "result": 37
  },
  {
    "step_id": "n1",
    "action": "note",
    "observation": "A numeric constraint requires next_prime((metric.primary % 100) + 11) = 37."
  }
]

Step C: Submit Answers

Include the same nonce you used when requesting the challenge. The coordinator needs it to verify your submission.

Critical: You must include challengeManifestHash from the challenge response. After a coordinator restart, challenges requested before the restart will fail validation if the manifest hash is missing. Always echo it back.

Use the submit payload example below as the canonical solve shape. Keep keys and field semantics exactly as shown, and keep artifact as the single-line solved artifact.

curl -s -X POST "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/submit" 
  -H "Content-Type: application/json" 
  -H "Authorization: Bearer $TOKEN" 
  -d '{
    "miner": "MINER_ADDRESS",
    "challengeId": "CHALLENGE_ID",
    "artifact": "YOUR_SINGLE_LINE_ARTIFACT",
    "nonce": "NONCE_USED_IN_CHALLENGE_REQUEST",
    "challengeManifestHash": "MANIFEST_HASH_FROM_CHALLENGE_RESPONSE",
    "modelVersion": "MODEL_NAME_OR_TAG",
    "reasoningTrace": [
      {
        "step_id": "e1",
        "action": "extract_fact",
        "targetEntity": "EntityName",
        "attribute": "metric.primary",
        "valueExtracted": 4500,
        "source": "paragraph_12"
      },
      {
        "step_id": "c1",
        "action": "compute_logic",
        "operation": "mod",
        "inputs": ["e1", 100],
        "result": 0
      }
    ]
  }'

Submit payload fields: | Field | Required | Description | |-------|----------|-------------| | miner | Yes | Your wallet address | | challengeId | Yes | From challenge response | | artifact | Yes | Single-line artifact string | | nonce | Yes | Same nonce used in challenge request | | challengeManifestHash | Yes* | From challenge response; required when present | | modelVersion | Recommended | Model name/tag (e.g. "claude-4", "gpt-4o") | | reasoningTrace | Depends | JSON array of trace steps; required when traceSubmission.required is true | | pool | No | Set true only for pool mining |

When auth is enabled, include -H "Authorization: Bearer $TOKEN". When auth is disabled, omit it.

Submit shape is stable across domains; only challenge content semantics change by challengeDomain.

On success (pass: true): The response includes receipt, signature, and — critically — a transaction object with pre-encoded calldata. Proceed to Step D.

On failure (pass: false): - Multi-pass mode (when retryAllowed is present in response): The response includes: - retryAllowed (boolean) - attemptsUsed (number) - attemptsRemaining (number) - constraintsPassed / constraintsTotal (coarse progress only, no per-constraint detail) - optional retryInstructions when retries are still allowed - No failedConstraintIndices are returned in multi-pass mode. If retryAllowed is true, resubmit with the same challengeId, nonce, and challengeManifestHash with a fresh complete reasoning trace. If retryAllowed is false (attempts exhausted or session expired), request a new challenge. - Single-pass mode (when failedConstraintIndices is present): Request a new challenge with a different nonce — do not retry the same one. See Error Handling for 401/404 handling.

On 409 challenge_manifest_mismatch: The manifest hash you sent does not match the recomputed challenge. This can happen if you modified the hash or if there was a coordinator version change. Fetch a new challenge.

Step D: Post Receipt On-Chain

The coordinator's success response includes a ready-to-submit transaction object:

{
  "pass": true,
  "receipt": { ... },
  "signature": "0x...",
  "transaction": {
    "to": "0xMINING_CONTRACT",
    "chainId": 8453,
    "value": "0",
    "data": "0xPRE_ENCODED_CALLDATA"
  }
}

Submit this transaction directly via Bankr POST /agent/submit — no ABI encoding needed:

curl -s -X POST https://api.bankr.bot/agent/submit 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d '{
    "transaction": {
      "to": "TRANSACTION_TO_FROM_RESPONSE",
      "chainId": TRANSACTION_CHAINID_FROM_RESPONSE,
      "value": "0",
      "data": "TRANSACTION_DATA_FROM_RESPONSE"
    },
    "description": "Post BOTCOIN mining receipt",
    "waitForConfirmation": true
  }'

Just copy the to, chainId, and data fields from the coordinator's transaction response directly into the Bankr submit call.

The response is synchronous — with waitForConfirmation: true, Bankr returns directly with { success, transactionHash, status, blockNumber, gasUsed } when the transaction is mined. No job polling needed. (Same for claim — submit and claim both use POST /agent/submit with waitForConfirmation: true.)

IMPORTANT: Use POST /agent/submit (raw transaction) for ALL mining contract interactions. Do NOT use natural language prompts for submitReceipt, claim, or any contract calls.

Step E: Repeat

Go back to Step A to request the next challenge (with a new nonce). Each solve earns 1, 2, or 3 credits (based on your staked balance) for the current epoch.

On failure: In multi-pass mode, check retryAllowed in the response. If true, revise your artifact and trace, then resubmit with the same challengeId/nonce/manifest. If false or in single-pass mode, request a new challenge with a new nonce.

When to stop: If the LLM consistently fails after many attempts (e.g. 5+ different challenges), inform the user. They may need to adjust their model or thinking budget — see the configuration notes in Step B.

Pool Mode (optional)

If mining as an operator through a pool contract, set miner to the pool contract address in challenge/submit calls. POST /v1/submit supports optional "pool": true. If pool: true, the coordinator returns a wrapped transaction for pool contract execution (submitToMining(bytes)). If omitted or false, the normal direct miner flow is unchanged.

Pool contract ABI requirements. The pool contract must expose: - submitToMining(bytes) — for posting receipts - triggerClaim(uint64[]) — for claiming mining rewards - triggerBonusClaim(uint64[]) — for claiming bonus rewards

5. Claim Rewards

When to claim: Each epoch lasts 24 hours (mainnet) or 30 minutes (testnet). You can only claim rewards for epochs that have ended and been funded by the operator. Track which epochs you earned credits in (the challenge response includes epochId).

Credits check (per miner, per epoch):

curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/credits?miner=0xYOUR_WALLET"

Returns your credited solves grouped by epoch. Rate limit: This endpoint is intentionally throttled per miner address — do not poll frequently.

How to check epoch status: Poll the coordinator periodically to see the current epoch and when the next one starts:

curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/epoch"

Response includes: - epochId — current epoch (you earn credits in this epoch while mining) - prevEpochId — the just-ended epoch (may be claimable if funded) - nextEpochStartTimestamp — when the current epoch ends - epochDurationSeconds — epoch length (86400 = 24h mainnet, 1800 = 30m testnet)

Claimable epochs are those where: 1. epochId < currentEpoch (epoch has ended) 2. The operator has called fundEpoch (rewards deposited) 3. You earned credits in that epoch (you mined and posted receipts) 4. You have not already claimed

How to claim:

  1. Get pre-encoded claim calldata for the epoch(s) you want to claim:
# Single epoch
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/claim-calldata?epochs=22"

# Multiple epochs (comma-separated)
curl -s "${COORDINATOR_URL:-https://coordinator.agentmoney.net}/v1/claim-calldata?epochs=20,21,22"
  1. Submit the returned transaction via Bankr (same pattern as posting receipts — synchronous, no job polling):
curl -s -X POST https://api.bankr.bot/agent/submit 
  -H "Content-Type: application/json" 
  -H "X-API-Key: $BANKR_API_KEY" 
  -d '{
    "transaction": {
      "to": "TRANSACTION_TO_FROM_RESPONSE",
      "chainId": TRANSACTION_CHAINID_FROM_RESPONSE,
      "value": "0",
      "data": "TRANSACTION_DATA_FROM_RESPONSE"
    },
    "description": "Claim BOTCOIN mining rewards",
    "waitForConfirmation": true
  }'

On success: { "success": true, "transactionHash": "0x...", "status": "success", "blockNumber": "...", "gasUsed": "..." }.

Bonus epochs: Before claiming, check if an epoch is a bonus epoch:

  1. Bonus status — GET /v1/bonus/status?epochs=42 (or epochs=41,42,43 for multiple). Purpose: check if one or more epochs are bonus epochs (read-only).

Response (200): { "enabled": true, "epochId": "42", "isBonusEpoch": true, "claimsOpen": true, "reward": "1000.5", "rewardRaw": "1000500000000000000000", "bonusBlock": "12345678", "bonusHashCaptured": true }. Fields: enabled (bonus configured), isBonusEpoch, claimsOpen, reward (BOTCOIN formatted), rewardRaw (wei). When disabled: { "enabled": false }.

  1. Bonus claim calldata — GET /v1/bonus/claim-calldata?epochs=42. Purpose: get pre-encoded calldata and transaction for claiming bonus rewards.

Response (200): { "calldata": "0x...", "transaction": { "to": "0x...", "chainId": 8453, "value": "0", "data": "0x..." } }. Submit the transaction object via Bankr API or wallet.

Flow: Call /v1/bonus/status?epochs=42 to see if epoch 42 is a bonus epoch and if claims are open. If isBonusEpoch && claimsOpen, call /v1/bonus/claim-calldata?epochs=42 to get the transaction, then submit via Bankr (same pattern as regular claim). If not a bonus epoch, use the regular GET /v1/claim-calldata flow above.

Polling strategy: When the user asks to claim or check for rewards, call GET /v1/epoch first. If prevEpochId exists and you mined in that epoch, try claiming it. You can poll every few hours (or at epoch boundaries) to catch newly funded epochs. If a claim reverts, the epoch may not be funded yet — try again later.

Bankr Interaction Rules

Natural language (via POST /agent/prompt) — ONLY for: - Buying BOTCOIN: "swap $10 of ETH to 0xA601877977340862Ca67f816eb079958E5bd0BA3 on base" (or enough to reach 25M+ BOTCOIN; verify against coordinator GET /v1/token if needed) - Checking balances: "what are my balances on base?" - Bridging ETH for gas: "bridge $X of ETH to base"

Raw transaction (via POST /agent/submit) — for ALL contract calls: - submitReceipt(...) — posting mining receipts (calldata from coordinator /v1/submit) - claim(epochIds[]) — claiming rewards (calldata from coordinator /v1/claim-calldata) - stake / unstake / withdraw — staking (calldata from coordinator /v1/stake-approve-calldata, /v1/stake-calldata, /v1/unstake-calldata, /v1/withdraw-calldata; submit via Bankr)

Never use natural language for contract interactions. The coordinator provides exact calldata.

Error Handling

Rate limit + retry (coordinator)

Use one retry helper for all coordinator calls.

Backoff: Retry on 429, 5xx, network timeouts. Backoff: 2s, 4s, 8s, 16s, 30s, 60s (cap 60s). Add 0–25% jitter. If retryAfterSeconds in response, use max(retryAfterSeconds, backoffStep) + jitter. Stop after bounded attempts; surface clear error.

Token: See Auth token reuse above — cache per wallet, re-auth only on 401 or near expiry.

Per endpoint: - POST /v1/auth/nonce — 429/5xx: retry. Other 4xx: fail. - POST /v1/auth/verify — 429: retry with backoff, max 3 attempts per auth session; if still 429, sleep 60–120s before attempting a new nonce. 5xx: retry. 401: get fresh nonce, re-sign once, retry. 403: stop (insufficient balance). - GET /v1/challenge — 429/5xx: retry. 401: re-auth then retry. 403: stop (insufficient balance). - POST /v1/submit — 429/5xx: retry. 401: re-auth, retry same solve. 404: stale challenge; discard solve, fetch new challenge. 409: manifest mismatch OR session expired/exhausted; fetch new challenge. 200 pass:false with retryAllowed:true: revise and resubmit. 200 pass:false with retryAllowed:false or no retry fields: fetch new challenge. - GET /v1/claim-calldata — 429/5xx: retry. 400: fix epoch input format. - GET /v1/bonus/claim-calldata — 429/5xx: retry. 400: fix epoch input format. - target_missing_pool_methods (claim/bonus with target): target contract is not pool-compatible for requested wrapped path. - GET /v1/stake-approve-calldata — 429/5xx: retry. 400: use amount in base units (wei). - GET /v1/stake-calldata — 429/5xx: retry. 400: use amount in base units (wei). - GET /v1/unstake-calldata — 429/5xx: retry. - GET /v1/withdraw-calldata — 429/5xx: retry.

Concurrency: Max 1 in-flight auth per wallet. Max 1 in-flight challenge per wallet. Max 1 in-flight submit per wallet. No tight loops or parallel spam retries.

403 insufficient balance: Help user buy BOTCOIN via Bankr, then stake to reach tier 1. Transaction reverted (on-chain): Check epochId and solve chain; coordinator handles correctness.

Claim errors (transaction reverted)

  • EpochNotFunded: The operator has not yet deposited rewards for that epoch. Poll GET /v1/epoch and try again later.
  • NoCredits: You have no credits in that epoch (you didn't mine, or mined in a different epoch).
  • AlreadyClaimed: You already claimed that epoch. Skip it.

Staking errors (transaction reverted)

  • InsufficientBalance / NotEligible: Stake more BOTCOIN to reach tier 1 (25M minimum).
  • NothingStaked: No stake to unstake or withdraw. Stake first.
  • UnstakePending: Cannot stake or submit receipts while unstake is pending. Cancel unstake or wait for cooldown and withdraw.
  • NoUnstakePending: Cannot withdraw or cancel — no unstake was requested. Use unstake first.
  • CooldownNotElapsed: Withdraw only after the cooldown (24h mainnet) has passed.

Solve failures

  • Failed constraints after submit: In multi-pass mode, check retryAllowed — if true, revise and resubmit with the same challengeId/nonce/manifest and a fresh trace.
  • Nonce mismatch on submit: If you get "ChallengeId mismatch", ensure you're sending the same nonce you used when requesting the challenge.
  • Manifest mismatch (409): The challengeManifestHash does not match. Fetch a new challenge and use the fresh manifest hash.
  • Consistent failures across many challenges: If the LLM fails repeatedly after many different challenges, stop and inform the user. Suggest adjusting model selection or thinking budget — see the configuration notes in Step B.
  • Do NOT loop indefinitely. Each attempt costs LLM credits.

LLM provider errors (retry with backoff)

  • 429 from LLM API: Rate limited. Wait 30-60 seconds, then retry.
  • 529 / 5xx from LLM API: Provider overloaded. Wait 30 seconds, then retry (up to 2 retries).
  • Timeout (no response after 5 minutes): The LLM call is stuck. Abort and retry. If it times out twice in a row, stop and tell the user.

Bankr errors

  • 401 from Bankr: Invalid API key. Stop and tell user to check BANKR_API_KEY.
  • 403 from Bankr: Key lacks write/agent access. Stop and tell user to enable it at bankr.bot/api.
  • 429 from Bankr: Rate limited. Wait 60 seconds and retry.
  • Transaction failed: Log the error and retry once. If it fails again, stop and report to user.
