How this service works

7-chain pre-trade smart contract bytecode, SPL/Token-2022 authority & multi-DEX liquidity risk oracle across Base (8453), Solana, Ethereum (1), Arbitrum (42161), Optimism (10), Polygon (137), and BNB Smart Chain (56). Instant x402 v2 settlement in Base USDC or BSC USDC.

Output

Returns a JSON object with an 'audit' block containing boolean flags (isProxy, mintSelector, hasSelfdestruct, blacklistSelector), a 'verdict' string (e.g. SAFE_TO_EXECUTE), and an integer 'riskScore' (lower is safer).

Example use cases

DeFi bot pre-swap safety gate

“I'm about to buy a new token on Base — can you audit contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 for me and tell me if it's safe to execute, including whether it's a proxy or has any mint selectors?”

Solana meme coin rug check

“There's a new SPL token on Solana everyone is hyped about — can you check its token authority and give me a risk score before I put any money in?”

BSC token blacklist scan before trading

“Before I trade this BNB Smart Chain token at address 0x55d398326f99059fF775485246999027B3197955, can you verify the contract for blacklist selectors or honeypot traps and tell me the verdict?”

Side effects

Invalid or unsupported contract/token address returns error
