Token approvals checker

Permission you gave a contract to move one of your tokens later, without asking you again, usually so an exchange or app can swap or deposit it. It stays in force until you set it back to zero, and an unlimited approval covers every token of that kind you will ever hold.

Every approval emits a public Approval event. Wardcrest reads all of them for your address from the block explorer’s log index, then asks the chain what each spender may still take today, so approvals you already revoked or used up drop out.

Critical: the spender is labelled a scam, a hack or a sanctioned address. High: the spender is an ordinary wallet rather than an app’s contract (a common sign of a phishing approval) or unverified code with an unlimited allowance. Medium: an unlimited allowance to a contract Wardcrest cannot identify. Unlimited approvals to well-known apps are normal and stay low.

From your own wallet: many wallets have an approvals screen; otherwise send approve with an amount of 0 to the token contract. Each result shows the exact transaction. Check it before you confirm (it goes to the token contract and moves nothing) and never sign a “revoke” that asks for a permit signature or for tokens.

No. It reads public data for any address you paste. It never asks you to connect a wallet or sign anything, and it cannot revoke anything for you.

NFT approvals (setApprovalForAll), allowances inside Uniswap’s Permit2 (revoking the token’s approval to Permit2 cuts them all off), and chains other than the one you pick. On BNB Smart Chain the checker needs an Etherscan key on the server. Very active wallets may have more approval events than one check reads; the page says so when that happens.
