Connecting a wallet only starts a session
Use least-privilege thinking for token approvals: verify the spender, limit the allowance when practical and review whether the permission is still needed after use. A DApp connection usually reveals one or more public addresses; it does not automatically authorize asset movement. Later signature, approval or transaction requests can create real consequences, so each request should be reviewed independently.
Before connecting, verify the domain, protocol and navigation path. Lookalike characters, unexpected subdomains and unfamiliar redirects are reasons to stop and re-check.
Message signatures and transaction signatures differ
A message signature may be used for login or proof of address control, while a transaction signature can submit a transfer, approval or contract call. A page labelled “Sign in” can still present a request with broader meaning than the button text suggests.
If the wallet preview does not match what the DApp says will happen, do not confirm.
- Confirm the network and target first.
- Then verify the address, contract or permission scope.
- Finally review the fee, result and verification method.
Token approvals define future permissions
An approval usually authorizes a contract to use a token under specified conditions rather than transferring the token immediately. Large or unlimited allowances increase the consequences if the approved contract is later abused.
Review the spender, token, network and allowance amount. Remove approvals that no longer serve a purpose when appropriate.
Disconnecting is not the same as revoking
Ending a wallet session stops the current connection but normally does not erase approvals already recorded on-chain. Revocation requires a separate on-chain action on the relevant network.
That revocation transaction should be reviewed with the same care as any other contract interaction.
Build a practical review process for Token Approvals
Turn the topic into a repeatable checklist: define the intended result, note the network, asset, address or contract, estimate the fee and decide how you will verify the final state. This separates what you expected to happen from what actually happened on-chain. For Token Approvals, clarity at each step matters more than speed.
If the result differs from expectations, preserve the transaction hash, network name, error message and request details shown by the wallet. Those details can support troubleshooting without exposing a seed phrase, private key or verification code.
