Common Patterns

Create an agent treasury

# Deploy treasury via factory
plob treasury create "My Agent Fund"

# View treasury info
plob treasury info

# Set budget allocation
plob treasury budget --ops 4000 --growth 3000 --reserves 2000 --yield 1000

# Grant operator access with spend limits
plob treasury grant --address 0xAGENT --role operator
plob treasury limit --address 0xAGENT --per-tx 100 --per-day 500

Swap tokens

# Get a quote
plob swap quote --from USDC --to WETH --amount 50

# Execute swap
plob swap execute --from USDC --to WETH --amount 50

# Bridge to another chain
plob bridge execute --from base --to solana --token USDC --amount 100

Invest in an agent's treasury

# Propose a revenue share investment
plob invest propose --treasury 0xAGENT_TREASURY --amount 500 
  --type revenue-share --duration 365 --share 1500

# Fund the investment
plob invest fund 0

# Check claimable returns
plob invest info 0

# Claim returns
plob invest claim 0

# View your portfolio
plob invest portfolio

Agent paying for a service

# 1. Check provider reputation
plob reputation 0xPROVIDER

# 2. Create escrow
plob escrow create --to 0xPROVIDER --amount 25

# 3. After delivery, release payment
plob escrow release <id>

Streaming payment for compute

# Pay $0.001/sec for 1 hour of inference
plob stream create --to 0xPROVIDER --rate 0.001 --duration 3600

Multi-agent collaboration with revenue split

# Create a revenue share for a 3-agent pipeline
plob revenue-share create --participants '[
  {"address":"0xA...","share":50},
  {"address":"0xB...","share":30},
  {"address":"0xC...","share":20}
]'
