Tool selection guide
Wallet security tools: approvals and transaction inspection
Choose the tool by the permission you are trying to understand. An approval dashboard shows what a spender may access. A pre-signing preview estimates the effects of a proposed interaction. Neither restores a disclosed seed phrase or guarantees how a contract will behave after state changes.
Sources checked . Public interface/documentation reviewed; no wallet was connected and no approval was changed.
Distinguish signature deadlines and allowance expiration.
Decide what your review needs
- Identify the network, account and permission type. Token allowances and signature-based authorizations can require different investigation paths.
- Inspect the spender address and the relevant contract context. A familiar label does not establish that the address is the intended deployment.
- Review the exact transaction or signature prompt before signing. A warning-free preview is only one input to the decision.
- For a compromised key, separate migration to a secure authority from allowance cleanup. Removing one allowance does not remove control from someone holding the key.
Compare inputs, results and limits
| Tool & access | Input → output | When it fits | Limits & source |
|---|---|---|---|
| Revoke.cash EVM | Input: Wallet address and selected network Output: Approval inventory and proposed revocation actions | You need to inspect allowances and identify a spender before an authorized revocation. | Revocation requires an on-chain transaction and does not recover assets already transferred. Documentation reviewed. Official source |
| Rabby Wallet EVM | Input: A proposed EVM wallet interaction Output: Pre-signing transaction information and risk prompts | You want a wallet interface that presents transaction context for review. | Simulation and warnings cannot guarantee the safety of a transaction or protect a disclosed seed phrase. Documentation reviewed. Official source |
| Pocket Universe EVM | Input: Supported browser-wallet interaction Output: Transaction preview and scam-screening signals | You want an additional review layer and can verify current wallet/chain compatibility. | Check current chain and wallet support.

Public artifact walkthrough
Inspect first, then review a revocation as a new transaction
Revoke.cash offers address entry as an inspection path as well as wallet connection. Use the read-only path to identify the network, token and spender in question. Revocation is a separate on-chain action and needs its own review. The site's current interface also describes paid options, so verify fees and the exact action rather than assuming every workflow is free.
- Enter the public address for inspection and verify that the selected network is the one where the permission exists.
- Compare the spender and allowance with the intended application. Preserve the observation time because permissions can change.
- If authorized to revoke, review the transaction and its fees in the wallet. Verify the resulting allowance after confirmation; do not claim that previously transferred assets were recovered.
