Is it safe to pay this address?
Is it safe to pay this address? One check before sending or accepting crypto: OFAC SDN sanctions screen, wallet age, EOA or contract, first funder and recent large transfers on Base, Ethereum, Arbitrum, Optimism or Polygon (wallet kind and activity on Solana), plus the token's 0-100 risk score when a token is given. Returns ok, caution or block with plain reasons and each check in full. Rules-based, not legal advice.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
