ApprovalWatch
ApprovalWatch is a read-only token approval checker that explains which contracts can spend tokens from a public wallet address.
What is ApprovalWatch?
ApprovalWatch scans the token approvals of a public wallet address on Ethereum, BNB Chain, Base, Arbitrum and Polygon and describes them in plain English. Reports show which contracts can spend which tokens, flag unlimited and old approvals, and link each finding to a block explorer for verification. The service never connects to a wallet, never asks for keys and never executes revokes, so users cancel approvals themselves through linked tools such as Revoke.cash. Each scan covers the most recent 200,000 blocks, so older approvals may not appear. Manual scans of one wallet are free, a one-off paid scan is available, and Starter and Plus subscriptions add daily rescans and email alerts.
