## Findings

- **warn** Base64 strings in `dex_liquidity_router` ([base64-blob](https://anlyon.dev/methodology#base64-blob))

```untrusted-server-text
The input schema at properties.token_address.description contains a 42-character base64 string.

inputSchema.properties.token_address.description: "...token on Base (e.g. 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913)."
```

```
