  description: Base L2 USDC payment terminal: create an EIP-681 payment-request URL (ethereum:<usdc>@8453/transfer?address=<to>&uint256=<raw>) that a customer wallet opens to sign a USDC transfer, then verify on-chain whether the payment has landed via eth_getTransactionReceipt or eth_getLogs scanning USDC Transfer events. T1 custody: no private keys held, no signing, no broadcasting. Operations: create_payment (needs recipient, amount) and check_payment (needs recipient, optional tx_hash).
  schema:      {"properties":{"amount":{"description":"Amount in human-readable USDC (e.g. \"25.50\"). Required for create_payment.","type":"string"},"op":{"default":"create_payment","description":"Operation to perform. create_payment builds an EIP-681 Base USDC URL; check_payment verifies on-chain payment.","enum":["create_payment","check_payment"],"type":"string"},"recipient":{"description":"Recipient Ethereum address (0x...). Required for both operations.","type":"string"},"tx_hash":{"description":"Transaction hash to verify. Optional for check_payment; if omitted, scans recent blocks.","type":"string"},"usdc_address":{"description":"USDC contract address override (optional). Defaults to native Base USDC.","type":"string"}},"required":[],"type":"object"}

━━━ TEST 1: create_payment (EIP-681 USDC URL) ━━━
  success: true
  output:  💳 Base USDC payment request created:
URL: ethereum:0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913@8453/transfer?address=0x3d6B517CF4710cB9501CbB69D44B054AC2021f27&uint256=25000000
Amount: 25 USDC (raw: 25000000)
Recipient: 0x3d6B517CF4710cB9501CbB69D44B054AC2021f27
USDC contract: 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
Chain: Base (8453).

Share the URL / QR with the customer. Their wallet will prompt to sign a USDC transfer. To check if paid, call this tool again with check_payment and the recipient address (and optional tx hash).
  ✓ Valid EIP-681 Base USDC payment URL generated.

━━━ TEST 2: check_payment (Base mainnet, expecting unpaid) ━━━
  success: true
  output:  ⏳ NOT PAID — no USDC transfers to 0x000000000000000000000000000000000000dEaD found in the scanned block range.
Ask the customer to sign the payment URL. Poll again in a few seconds.
  ✓ Base RPC queried live (eth_blockNumber + eth_getLogs), correctly unpaid.

━━━ TEST 3: error handling (invalid recipient address) ━━━
  success: false
  error:   Some("recipient 'not-an-address' is not a valid Ethereum address")
  ✓ Plugin correctly rejects a malformed address.

━━━ TEST 4: error handling (missing recipient) ━━━
  success: false
  error:   Some("recipient address is required")
  ✓ Plugin correctly rejects missing recipient.
