Treat a connection as a session, not blanket consent
A DApp connection usually exposes a public account address and network context so the site can build a session. It does not automatically transfer funds and it does not make later requests trustworthy. Every new signature, approval, or transaction deserves a fresh review.
When a site asks to switch networks, confirm that the requested chain is actually part of the task. A network change alters the wallet context; it does not move assets between chains.
Separate login signatures from transactions
A login message, typed-data signature, token approval, and on-chain transaction can have very different consequences. Read the request type, originating site, selected account, network, visible fields, and any contract information before signing.
If the request is not explainable from the action you just initiated, reject it and verify the site instead of clicking through.
Approvals create persistent on-chain permissions
Token approvals name a spender and an allowance. The amount should match the intended use, and a broad allowance should be a deliberate choice rather than a default accepted without review.
Disconnecting a website generally does not erase an allowance already recorded on-chain, so connection cleanup and approval cleanup are separate tasks.
Contract interactions have their own risk boundary
A wallet can present and sign a contract call, but it cannot guarantee the quality of third-party code, upgrade controls, external dependencies, or market conditions. Verify the destination contract and understand the expected state change.
Confirmed blockchain transactions are generally not reversible by the wallet alone.
Close the loop after using a DApp
After an interaction, review the resulting transaction, disconnect sessions you no longer need, and inspect relevant approvals. A transaction hash provides a public reference for checking what actually happened on the selected network.
This final review is especially useful when a front-end status message does not match the wallet or block explorer.
Connecting a wallet does not mean every later request should be approved.
A repeatable Web3 review sequence
Start by naming the task: sign in, swap, deposit, stake, or perform another contract action. Then verify the domain, account, and network before opening any wallet prompt.
When a Web3 request does not match your intent
For each prompt, ask who initiated it, on which chain, from which account, what is being signed, and whether it affects assets or permissions. If one of those answers is unclear, stop and investigate.
After completion, verify the chain result and check whether a lasting approval remains. A seed phrase, private key, or verification code is never required for a normal DApp connection.
- Verify the domain and purpose before connecting
- Review every signature, approval, and transaction independently
- Keep allowances no broader than the real use case
- Check transaction state, sessions, and approvals afterward
