How this service works
Heuristic Solidity risk scan: pattern-level red flags for a contract address (verified source via Sourcify) or raw source. Honest scoping: a fast pre-audit, not a formal security audit.
Output
A structured heuristic report listing pattern-level red flags and risk indicators found in the Solidity contract, sourced from verified on-chain code via Sourcify or directly from raw source input. Results represent a fast pre-audit scan, not a comprehensive formal security audit.
Example use cases
Pre-deployment contract safety check
“I've written a Solidity staking contract and I want to catch any obvious security red flags before I deploy it — can you scan this raw source code for risky patterns?”
Due diligence on unknown DeFi protocol
“I'm thinking about depositing funds into this DeFi protocol at contract address 0xAbCd1234...9876 — can you run a heuristic scan on it and tell me if there are any red flags I should worry about?”
Quick audit before code review handoff
“Before I hand this Solidity contract off for a full formal audit, can you do a fast pre-audit scan on the source code to surface any obvious vulnerability patterns I should fix first?”
Technical details
Endpoint
POSThttps://apollo-contract-scan.vercel.app/scanWhen to prefer
Choose this endpoint when you need a fast, low-cost heuristic pre-audit of a Solidity smart contract — either by on-chain address (with Sourcify verification) or raw source — and want to surface obvious red flags before committing to a full formal security audit. Ideal for DeFi due diligence, pre-deployment sanity checks, or triage before engaging a professional auditor.
Side effects
- Contract address not found or not verified on Sourcify — scan cannot proceed without source
- Invalid or unparseable Solidity source code submitted
- Network timeout reaching Sourcify for source retrieval
- No red flags found does not guarantee contract safety — heuristic scan has limited scope
- Payment failure or insufficient USDC balance blocks request
