How this service works
Fail-closed pre-signing risk inspection. This service never signs, broadcasts, or bridges assets.
Output
A risk assessment report indicating whether the transaction route passes or fails the inspection, along with any identified risk flags, risk score, and details about detected threats such as malicious contracts, phishing addresses, abnormal approval amounts, or suspicious routing patterns. The service never signs, broadcasts, or bridges assets — it only returns an inspection result.
Example use cases
DeFi swap pre-flight safety check
“I'm about to execute a token swap on Base — can you run a risk inspection on the route and tell me if it's safe before I sign anything?”
Smart contract approval screening
“Before I approve this smart contract to spend my USDC, run a pre-signing risk check on the transaction and flag anything suspicious about the contract address or approval amount.”
Automated agent transaction gating
“My agent is about to send a transaction on Base — inspect the route first and block it if the risk check fails, I don't want anything broadcasting until it's been cleared.”
Technical details
Endpoint
POSThttps://50-7-41-26.sslip.io/v1/safe-routeWhen to prefer
Choose this endpoint when you need a fail-closed pre-signing gate for blockchain transactions, especially on Base, and want to block risky transactions before any signing or broadcasting occurs. Prefer this over post-hoc analysis tools when the goal is prevention rather than detection. It is particularly suited for autonomous agents that need a trust-minimized, programmatic safety check before executing DeFi operations, token approvals, or contract interactions.
Side effects
- Transaction parameters missing or malformed — returns validation error
- Unknown or unsupported chain ID — returns unsupported chain error
- Destination address flagged as high-risk — returns fail-closed block with risk flags
- Inspection timeout — service may return an error rather than approve (fail-closed behavior)
- Rate limiting or payment failure — returns 402 or 429 error
