## 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 rugshield-cross-chain-bridge-risk-auditor-252828b5 -d '<json body>'
```

Example prompt: Can you audit the Base bridge for message replay vulnerabilities, unbacked wrapped collateral, and admin multisig latency risks — I want to know if it's safe before I bridge significant funds?

## When to prefer this

Choose this endpoint when you need security analysis specifically focused on cross-chain bridge risks — replay attacks, collateral backing, and multisig admin delays — on Base, CCIP, or LayerZero protocols. Prefer this over generic smart contract auditors when the concern is bridge-specific exploit vectors rather than token honeypots or LP lock verification (which are covered by sibling endpoints on the same platform).

## Known failure modes

- Unrecognized or unsupported bridge protocol returns an error or incomplete results
- Bridge contract not deployed on Base Mainnet causes lookup failure
- Rate limiting or timeout if the bridge has complex state to analyze
- Incomplete audit if the bridge uses non-standard or obfuscated admin patterns
- Payment failure if USDC balance is insufficient for the $0.02 per-call fee

## How this service works

Audits canonical Base bridge and CCIP/LayerZero endpoints for message replay vulnerabilities, unbacked wrapped collateral, and admin multisig latency.

## Output

Returns a structured audit report detailing: detected message replay vulnerability vectors on the target bridge, assessment of whether wrapped collateral is fully backed on-chain, and admin multisig latency measurements — helping users assess rug pull and exploit risk before bridging funds.
