# DeFi Shield Bridge Risk Assessment

> DeFi Shield Bridge Risk Assessment is a paid API for AI agents from defi-shield-hazel.vercel.app, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Assesses trust and risk for blockchain bridge protocols in DeFi, providing risk scores and safety signals for cross-chain bridges

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability defi-shield-hazel-vercel-app-c926ddbc -d '<json body>'
```

Example prompt: What's the trust and risk score for the Stargate bridge protocol before I move 10,000 USDC from Ethereum to Arbitrum — I need to know how safe it is and what the main risk factors are.

## When to prefer this

Use this endpoint when an agent or user needs to evaluate the safety of a specific DeFi bridge before executing a cross-chain transfer. Prefer this over generic protocol risk tools when the focus is specifically on bridge mechanics, cross-chain trust, and bridge-specific risk vectors such as validator centralization, audit history, and exploit history.

## Known failure modes

- Unknown or unsupported bridge protocol returns an error or low-confidence result
- Invalid or unrecognized contract address returns a validation error
- Network or chain not supported returns a scope error
- Service unavailable returns 5xx with no risk data
- Insufficient data for assessment returns partial or low-confidence score

## How this service works

Bridge trust and risk assessment

## Output

Returns a trust and risk assessment for the specified bridge protocol, including an overall risk score, safety signals, identified risk factors (e.g. smart contract vulnerabilities, centralization, audit status), and a recommendation on whether to proceed with a cross-chain transfer.
