SendCheck MCP Server 工具

3

FREE pre-send check of an EVM address: EIP-55 checksum verification (catches typos, dropped characters, clipboard malware) + a note that a passing checksum is a spell-check, not payee verification. Run this before paying for check_address.

Paid pre-send verification of one EVM address on one chain ($0.01 USDC via x402, EIP-3009 on Base): checksum, wallet-vs-contract, outgoing activity, native/USDC/USDT balances, leveled verdict with reasons and next action. TWO-PHASE: call without x_payment first to get the exact payment challenge (payTo, amount, asset), sign the USDC transfer, then call again with x_payment = the resulting X-Payment header to get the report. No account, no API key — the payment is the authentication.

Paid deep scan: the full verification across ALL FIVE chains (Base, Ethereum, Arbitrum, Optimism, Polygon) incl. wrong-network detection and USDC/USDT token-mismatch flags ($0.05 USDC via x402, EIP-3009 on Base). TWO-PHASE like check_address: first call returns the payment challenge; second call with x_payment returns the report.
