How this service works
Counterparty-risk verdict (allow, warn or block, with reasons) for an EVM address on Base, Ethereum, OP Mainnet, Arbitrum or Base Sepolia, for use before paying, approving or trusting it. Checks the OFAC SDN list and the Chainalysis sanctions oracle, account age, EOA or contract, EIP-7702 delegation, upgradeable proxies and code changes in the last 72 h, and token controls (mint, blacklist, pause, fees, owner).
Output
A structured verdict of allow, warn, or block, accompanied by a list of reasons covering: OFAC SDN list membership, Chainalysis sanctions oracle result, account age, whether the address is an EOA or contract, EIP-7702 delegation presence, upgradeable proxy detection, code changes in the last 72 hours, and token control flags (mint capability, blacklist, pause function, fees, ownership).
Example use cases
Pre-payment sanctions screening
“I'm about to pay 0xAbCd...1234 on Ethereum for a freelance invoice — can you check if that address is blocked by OFAC or flagged by Chainalysis before I send anything?”
DeFi contract approval safety check
“I want to approve a token spend to 0xDeFi...5678 on Arbitrum — can you tell me if that contract is an upgradeable proxy, has any mint or blacklist functions, or has had its code changed in the last 72 hours?”
Compliance gate for crypto payout pipeline
“We're about to batch-pay contractors and one of the wallets is 0xPay...9999 on OP Mainnet — give me the risk verdict and flag anything that would block or warn against sending funds there.”

Endpoint
POSThttps://x402-services.soldano.workers.dev/mcp?utm_source=zero.xyz#counterparty_risk_evmWhen to prefer
Choose this endpoint when you need a comprehensive, multi-signal compliance verdict for an EVM address before executing any financial action — particularly when you need both sanctions screening (OFAC + Chainalysis) AND smart-contract-level risk signals (proxy upgradeability, code changes, token controls) in a single call. Prefer it over generic blockchain explorers when you need a structured allow/warn/block decision rather than raw on-chain data, and over simple OFAC-only checks when contract-level risk matters.
Side effects
- Invalid or malformed EVM address returns an error
- Unsupported network identifier causes a rejection
- Chainalysis or OFAC oracle temporarily unavailable may return a degraded or partial verdict
- Rate limiting or payment failure (x402) if USDC payment not provided
- Address with no on-chain history may return limited metadata
