How this service works
ERC-20 approval risk scanner for wallets: flags unlimited allowances and unverified spender contracts before an agent authorizes a new one. Category: data.
Output
Returns a risk report for the scanned wallet, including a list of detected ERC-20 approvals, flags for unlimited (infinite) allowances, identification of unverified or suspicious spender contracts, and an overall risk assessment to help an agent decide whether it is safe to proceed with a new approval.
Example use cases
Pre-approval safety check for DeFi agent
“I'm about to let a yield farming protocol spend my USDC on Base — first scan wallet 0xAbC1234567890AbCdEf1234567890AbCdEf123456 on Base and tell me if there are any existing unlimited allowances or sketchy unverified contracts I should revoke first.”
Routine wallet security audit
“Can you do a full ERC-20 approval scan on my Polygon wallet 0xDeF9876543210dEfAbC9876543210dEfAbC98765 and flag anything that looks like an unlimited allowance or an unverified spender contract?”
Arbitrum wallet cleanup before migration
“I'm moving funds off Arbitrum — scan 0x1234AbCdEf5678901234AbCdEf5678901234AbCd on Arbitrum for any risky token approvals I should revoke before I go, especially unlimited ones or contracts that aren't verified.”
Technical details
Endpoint
GEThttps://agentforge-taupe.vercel.app/v1/approval-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or user needs to audit existing ERC-20 token allowances on a specific wallet before authorizing a new DeFi interaction. It is particularly valuable as a pre-transaction safety gate to prevent approval-based exploits such as allowance draining. Prefer it over generic transaction decoders or contract auditors when the specific concern is token approval risk across multiple EVM-compatible chains.
Side effects
- Invalid wallet address format — must be a valid 0x-prefixed 40-character hex address
- Unsupported chain value — must be one of: ethereum, base, polygon, arbitrum, optimism, avalanche
- Missing required wallet address parameter
- RPC or blockchain data unavailability causing incomplete scan results
- Payment failure (x402) if USDC balance or payment channel is insufficient
