A wallet permission review screen is the panel where a wallet or a third-party tool shows you the dapp connections and spending approvals currently attached to an address. This guide explains what each field on that screen means and how to use it to cancel what you no longer want to keep.
Start With the Question the Screen Answers
The screen exists to answer one question: which contracts can move assets on this address, and under what conditions? Everything else on the panel — spender names, token symbols, “unlimited” badges, revoke buttons — is decoration around that core answer.
Read it as a list of standing permissions, not as a receipt for a transaction you already made. A permission you granted three months ago and forgot about is still live, and it is exactly what this panel is showing you.
The Fields You Will See
Contract or dapp name. Usually the project name, sometimes the raw contract name. A name is a label, not proof of identity. Two different contracts can display the same name, and a name can be changed after deployment. Confirm the underlying contract address when the permission involves a meaningful amount.
Spender. This is the contract that is authorized to move tokens. It is the most important field on the screen, because “spender” and “the thing you interact with” are often not the same contract. Your token can be approved to a router, a staking contract, or a marketplace settlement contract.
Token and amount. What is authorized, and how much. Read the token by contract address rather than by symbol where the screen allows it. Symbols are not unique; a scam token can copy a legitimate ticker.
Approval type. Most allowances are unlimited (“infinite”, “unlimited”, “max uint256”). An unlimited approval does not mean the spender can take everything at any moment — it means the contract is not required to ask again for each transfer. The practical implication is that a compromised or malicious spender could drain up to the approved balance without a fresh prompt. Unlimited approvals are common in legitimate DeFi because they save gas on repeat swaps.
Last used. When the spender last moved funds under this approval. An approval that was never used is a dormant risk: it protects nothing you care about while remaining fully available to anyone who compromises the spender. Dormant approvals are the easiest thing to clean up and the easiest to forget.
Network. Which chain the approval lives on. This is the field people skip and the one that causes real losses. A revocation executed on one network does nothing to an identical approval on another. An address can hold separate, independent allowances on Ethereum, Base, Arbitrum and others.
Revoke control. The button that sets the approved amount back to zero. Revocation is a transaction: it costs gas, it needs signing, and it is usually irreversible in the sense that the allowance cannot be restored without a new approval.
A Procedure That Takes Two Minutes
- Open the wallet’s own permission or approval centre. Do this from the wallet, not from a link in a message or an advertisement.
- Confirm you are reviewing the address you intend to review. Wallets commonly hold several accounts, and a review of the wrong account produces a correct answer to the wrong question.
- Read down the spender column before anything else. For each entry, ask what that contract is and whether you still use it.
- Separate the list into three piles: contracts you use regularly, contracts you used once, and contracts you do not recognize.
- Revoke everything in the third pile immediately.
- For the second pile, revoke as well unless you expect to return within a short window. Re-approving later costs one transaction; a drained dormant approval costs everything in the allowance.
- Leave pile one alone, but re-check it periodically — a spender you trusted can be upgraded or taken over.
Reading Unlimited Approvals Without Panicking
Unlimited is a normal state in DeFi, not a red flag by itself. Protocols request it so that subsequent swaps and deposits do not each require a fresh approval. The decision is not “unlimited yes or no” but “does this contract deserve standing access to this token”.
A reasonable posture: unlimited approval for the few contracts you actively use on that token, limited or revoked approval for everything else.
What This Screen Does Not Tell You
- Whether the spender contract is secure. An approval can be perfectly valid and still point at code with a known vulnerability.
- Whether the price shown is current. Value figures in permission lists are often stale.
- Whether an attack is in progress. The screen shows permissions, not intent.
- Whether the token itself is legitimate. An approval of a scam token is still an approval.
- Whether someone else controls the address. A compromised device can sign its own revocations.
Common Mistakes
- Revoking on the wrong network and assuming the job is done.
- Revoking everything at once during an active session, breaking the dapp mid-action.
- Judging safety by the dapp’s brand name rather than the spender contract address.
- Leaving unlimited approvals on abandoned platforms simply because revoking feels like extra work.
- Treating the permission screen as a security audit. It is a list of authorizations, not a code review.
