Web3 & DApps

Start by verifying the DApp you are visiting

Start by making the real object of “Start by verifying the DApp you are visiting” explicit. Enter through a trusted source and check the domain. This is not just vocabulary: it tells you where the displayed data comes from, what the next confirmation can change and which facts should be checked on the relevant network. For Web3 & DApps, a familiar name, icon or interface is not enough by itself; network, account and intended action belong in the same decision.

What to verify in practice

A common mistake in this area is treating a plausible screen as complete evidence. Enter through a trusted source and check the domain. Familiar design, high search placement or pressure in a chat should not replace verification; phishing pages often rely on look-alike spelling. If a request unexpectedly asks for broader permission, a network switch, recovery material or an unexplained signature, stop and verify the source. Declining an action you cannot explain is safer than guessing what a contract or signature might do.

For this part of Web3 & DApps, keep one boundary in mind: A useful guide makes every step explainable and reviewable. When a request differs from your expectation, stop first and investigate before continuing. Decisions around “Start by verifying the DApp you are visiting” should be based on the current network, account and request rather than assuming a previous successful action makes the next one trustworthy. On-chain transactions generally cannot be unilaterally reversed by a wallet, and third-party DApps, smart contracts or bridges can introduce separate risks.

Wallet connection should expose only necessary account information

For Web3 & DApps, a practical review can be split into target, network and result. A connection can let a DApp see the selected account and request actions, but it should not require a seed phrase, private key or recovery phrase. Stop immediately if a webpage asks for those secrets. Then use public on-chain evidence where appropriate: Keep a transaction hash or another public reference for verification. This order reduces the chance that interface familiarity will hide an important detail and makes troubleshooting easier when something looks wrong.

A durable routine does not need to be complicated. For “Wallet connection should expose only necessary account information”, define the expected action, perform only what is necessary, and verify the result afterward. A connection can let a DApp see the selected account and request actions, but it should not require a seed phrase, private key or recovery phrase. Public references such as a transaction hash, network name or address can help with troubleshooting, while a seed phrase, private key or verification code should stay out of webpages, support tickets and chats.

Understand signatures and approvals one request at a time

A common mistake in this area is treating a plausible screen as complete evidence. A message signature may support login or consent, a transaction signature changes on-chain state, and token approval grants spending permission to a contract. They should not be treated as equivalent simply because each uses a confirmation prompt. If a request unexpectedly asks for broader permission, a network switch, recovery material or an unexplained signature, stop and verify the source. Declining an action you cannot explain is safer than guessing what a contract or signature might do.

Review sessions and permissions after the task

A durable routine does not need to be complicated. For “Review sessions and permissions after the task”, define the expected action, perform only what is necessary, and verify the result afterward. Disconnect sessions you no longer use and check for unnecessary token allowances. Public references such as a transaction hash, network name or address can help with troubleshooting, while a seed phrase, private key or verification code should stay out of webpages, support tickets and chats.

For Web3 & DApps, a practical review can be split into target, network and result. Disconnect sessions you no longer use and check for unnecessary token allowances. Keep important transaction hashes. Then use public on-chain evidence where appropriate: If a request looks abnormal, stop further interaction first and verify the on-chain state before doing anything else. This order reduces the chance that interface familiarity will hide an important detail and makes troubleshooting easier when something looks wrong.
