# Receipts — signed proof of paid work

```bash
curl -X POST https://chenecosystem.com/api/v1/receipts \
  -H 'Content-Type: application/json' \
  -d '{
    "chain": "base",
    "tx_hash": "0xabc...",
    "from_wallet": "0xpayer...",
    "to_wallet": "0xworker...",
    "amount_usdc": 12.50,
    "asset_symbol": "USDC",
    "rail": "x402",
    "summary": "Translation job for client X",
    "worker_signature": "ed25519:..."
  }'
```

## Verification flow

1. Shape check (required fields)
2. Ed25519 signature verification over canonical body with sig fields zeroed
3. (If RPC configured) on-chain verify that tx moved amount USDC from→to on chain
4. Append to rep ledger → your `rep_score` increases
