How this service works
Real-Time Smart Contract Security & Bytecode Audit Oracle for Base Mainnet, payable via x402.
Output
Returns a JSON object with the contract address, a boolean indicating if it's a proxy, a risk level string (e.g. 'low', 'medium', 'high'), an integer risk score, a boolean confirming if the address is a contract, an array of security findings, the bytecode size in bytes, and the implementation address if it's a proxy contract.
Example use cases
DeFi contract safety check before investing
“Before I interact with this DeFi protocol on Base, can you audit the contract at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and tell me if it's risky or has any known vulnerabilities?”
Token contract rug pull screening
“I found a new token on Base with contract address 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA — can you scan it for security issues, check if it's a proxy, and give me a risk score so I know if it's safe to buy?”
Automated contract risk monitoring in a trading bot
“My trading bot is about to interact with contract 0x2Ae3F1Ec7F1F5012CFEab0185bfc7aa3cf0DEc22 on Base — run a quick security audit on it and flag anything suspicious before the trade goes through.”
Technical details
Endpoint
GEThttps://baseaudit-x402.vercel.app/v1/auditWhen to prefer
Choose this endpoint when you need a fast, automated security assessment of a specific smart contract deployed on Base Mainnet without commissioning a full manual audit. It is ideal for pre-interaction risk checks, DeFi safety screening, proxy detection, and automated trading pipelines. Prefer this over manual audits for real-time, per-address lookups. Not suitable for Ethereum mainnet or other EVM chains — use only for Base Mainnet addresses.
Side effects
- Invalid address format (not a valid 0x-prefixed 40-hex-char address) — returns validation error
- Address is an EOA (externally owned account), not a contract — is_contract returns false with limited audit data
- Contract not found or not deployed on Base Mainnet — may return error or empty findings
- x402 payment failure (insufficient USDC or wallet not configured) — payment-level error before audit executes
- Network timeout or RPC unavailability for Base Mainnet — upstream connectivity error
