Elsa x402 DeFi Tools

This skill provides access to the Elsa DeFi API for portfolio management, token analysis, and swap execution using x402 micropayments.

Standard Operating Procedure

Budget Controls

  • Maximum $0.05 per API call (configurable)
  • Maximum $2.00 per day (configurable)
  • Maximum 30 calls per minute rate limit
  • Daily budget resets at midnight in configured timezone (default: UTC)

When executing swaps, follow this 4-step flow:

┌─────────────────────┐     ┌─────────────────────┐     ┌─────────────┐     ┌─────────────────────┐
│ 1. Get Quote        │ ──▶ │ 2. Dry Run          │ ──▶ │ 3. Confirm  │ ──▶ │ 4. Execute Pipeline │
│ elsa_get_swap_quote │     │ elsa_execute_swap_  │     │ [User says  │     │ elsa_pipeline_run_  │
│                     │     │ dry_run             │     │  "yes"]     │     │ and_wait            │
└─────────────────────┘     └─────────────────────┘     └─────────────┘     └─────────────────────┘

Step 1: Get Quote - Show user what they'll receive

npx tsx scripts/index.ts elsa_get_swap_quote '{
  "from_chain": "base", "from_token": "0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913",
  "from_amount": "10", "to_chain": "base", "to_token": "0x4200000000000000000000000000000000000006",
  "wallet_address": "0x...", "slippage": 0.5
}'

Step 2: Dry Run - Create pipeline, get pipeline_id

npx tsx scripts/index.ts elsa_execute_swap_dry_run '{...same params...}'
# Returns: { "pipeline_id": "abc-123", "confirmation_token": "..." }

Step 3: User Confirmation - Present results and wait for explicit "yes"

Step 4: Execute Pipeline - Sign and broadcast transactions

ELSA_ENABLE_EXECUTION_TOOLS=true npx tsx scripts/index.ts elsa_pipeline_run_and_wait '{
  "pipeline_id": "abc-123",
  "timeout_seconds": 180,
  "poll_interval_seconds": 3,
  "mode": "local_signer"
}'
# Automatically: signs approve tx → submits → signs swap tx → submits → returns tx hashes

Required Environment Variables

# For x402 API payments
PAYMENT_PRIVATE_KEY=0x...

# For signing swap transactions (optional - falls back to PAYMENT_PRIVATE_KEY)
TRADE_PRIVATE_KEY=0x...

# Enable execution tools
ELSA_ENABLE_EXECUTION_TOOLS=true

Critical Rules

  • NEVER execute swaps without showing the user the quote first
  • NEVER call execution tools in a loop
  • NEVER proceed if budget limits are exceeded
  • ALWAYS check elsa_budget_status if unsure about remaining budget
  • ALWAYS use dry-run mode first for any swap operation
