# ChainVerdict ERC-20 Token Safety Verdict

> ChainVerdict ERC-20 Token Safety Verdict is a paid API for AI agents from chainverdict.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Returns a hold/caution/avoid safety verdict with a risk score and detailed signals for an ERC-20 token on Base, covering ownership, mint authority, proxy upgradeability, liquidity, and transfer restrictions.

## 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 chainverdict-erc-20-token-safety-verdict-ad1b017a
```

Example prompt: Before I buy any of this token, can you run a safety check on the Base ERC-20 at 0x4ed4E862860beD51a9570b96d89aF5E1B0Efefed — I want to know if it's a hold, caution, or avoid, and what the key risk signals are like mint authority or transfer restrictions?

## When to prefer this

Choose this endpoint when you need a quick, structured risk classification of an ERC-20 token on Base before executing a trade, adding to a watchlist, or routing user funds — especially when you want signals across multiple risk dimensions (mint authority, proxy risk, liquidity concentration, transfer restrictions) in a single call. Prefer it over manual contract inspection for automated agent pipelines. Note it is heuristic static analysis, not a formal audit, so supplement with deeper review for large positions or novel contract patterns.

## Known failure modes

- Invalid or non-ERC-20 contract address returns an error or empty verdict
- Address does not exist on Base network — returns not-found error
- Proxy contract has changed implementation after analysis — verdict may be stale
- Highly obfuscated contracts may evade heuristic detection, producing a falsely optimistic score
- Network congestion on Base may delay on-chain reads
- Rate limiting or payment failure returns 402 or 429 error

## How this service works

Token safety check for an ERC-20 on Base: is this token a scam, a honeypot, or safe to hold? Examines ownership and mint authority, proxy upgradeability, liquidity and holder concentration, transfer-restriction patterns. Returns hold/caution/avoid with a score and the signals behind it. Heuristic static analysis, not a security audit — a proxy contract can change its implementation after this check.

## Output

A structured JSON response containing a verdict label (hold, caution, or avoid), a numeric risk score, and individual signal breakdowns covering ownership and mint authority risks, proxy upgradeability status, liquidity and holder concentration metrics, and any detected transfer-restriction patterns that informed the verdict.
