How this service works
Pre-trade safety checks for smart contracts and tokens. All paid routes use the x402 'exact' scheme settling in USDC on Base (eip155:8453). Every 402 carries a signed offer and every 200 a signed receipt (EIP-712) — see /.well-known/x402 -> signing.
Output
Returns a JSON object with a risk block (riskScore integer, riskLevel string, isProxy boolean, isContract boolean, and an array of labeled flags with weights), plus an alerts block showing mention counts across tracked on-chain channels broken down by category (securityAlert, whaleMovement, listing, other) and a note on data window coverage.
Example use cases
Pre-trade DeFi token safety check
“Before I swap into this token, can you scan the contract 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base and tell me if it's safe — risk score, any proxy shenanigans, and recent alerts?”
NFT contract audit before minting
“I'm about to mint from this Ethereum contract 0x1234567890abcdef1234567890abcdef12345678 — can you run a full risk check and let me know if it's an upgradeable proxy or has any security flags?”
Portfolio risk screening for held assets
“I hold a few tokens on Base — can you check the contract 0xabcdefabcdefabcdefabcdefabcdefabcdef1234 and give me the risk level and any active security alerts from monitored channels?”
Technical details
Endpoint
POSThttps://smartcontractrisk.0xhodhod.xyz/v1/full-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, multi-dimensional pre-trade risk score for a specific EVM contract before executing a DeFi trade or token purchase. It combines on-chain code analysis (proxy detection, upgrade patterns) with real-time social/alert monitoring in a single call. Prefer it over manual block explorer review or generic audit tools when you need machine-readable risk output for automated trading pipelines or agent-driven portfolio decisions on Base or Ethereum.
Side effects
- Invalid or non-0x-prefixed address returns a validation error
- Address not found on the specified chain returns isContract: false with no flags
- Unsupported chain value returns a 422 or enum validation error
- Payment not settled via x402 USDC on Base returns HTTP 402 with a signed offer
- Network timeout or RPC unavailability on Base/Ethereum may cause delayed or failed responses
