A wallet signature is not always a simple login confirmation. Depending on the request, a signature can authorise token allowances, approve an order, grant a contract broad permissions, or create an instruction that another service can submit later. Blind signing happens when someone approves a request without understanding what the wallet is actually being asked to authorise.
Read the request, not only the button
Before approving a signature or transaction, pause and check the connected site, the account and network, the action type, and the permissions involved. A familiar logo or a message saying “no gas” does not make a request harmless. If a wallet shows an unreadable payload, that is a reason to slow down—not a reason to approve quickly.
Questions to ask before approval
- Did I intentionally start this action on this exact site?
- Does the account and network match the asset or application I expect to use?
- Is the request a message, a token approval, a transaction, or a permit with ongoing consequences?
- Does the permission scope match the amount and duration I intended?
Reduce the blast radius
Use a separate wallet for unfamiliar applications, keep long-term assets away from routine signing activity, and periodically review token approvals. Hardware wallets and clear-signing interfaces can add useful context, but they do not remove the need to verify the destination and purpose of every approval.
