# Pre-trade safety

ChainRay combines token, contract, wallet, liquidity, tax, permission, and MEV signals before an agent acts.

## Decision contract

- Use GET /security-check/{address} for a compact decision context.
- Inspect token-risk, contract-scan, token-approval, credit-score, liquidity-depth, and MEV fields when the workflow needs detail.
- Treat verdicts as risk guidance, not a guarantee of execution or profitability.
- Check _proof, evidence, freshness, and degraded fields before acting.

The service returns explicit unsupported or degraded states when an upstream source or chain capability is unavailable.
