Web3 & DApps

Build the right model

Web3 & DApps makes more sense when DApp connections, account permissions, message signing, transaction signing, approval management are considered as parts of one on-chain workflow. Breaking an action into separate checks reduces mistakes caused by familiar-looking pages, similar links or urgent prompts.

During real use, confirm the active network and account first, then verify the object, scope and expected outcome related to DApp connections. Any action that changes assets, permissions or account state deserves a full review before confirmation.

Understand the on-chain relationship

During real use, confirm the active network and account first, then verify the object, scope and expected outcome related to DApp connections. Any action that changes assets, permissions or account state deserves a full review before confirmation.

For account permissions, prefer information that can be independently checked: the wallet transaction summary, the relevant network explorer, an explicit contract address or an official product page. The same address format can appear across different network contexts, so appearance alone is not enough to confirm the correct destination.

What to verify in practice

For account permissions, prefer information that can be independently checked: the wallet transaction summary, the relevant network explorer, an explicit contract address or an official product page. The same address format can appear across different network contexts, so appearance alone is not enough to confirm the correct destination.

When message signing is involved, separate display data from on-chain facts. Names, icons and fiat estimates may come from external data sources, while balances, transaction state and approvals should be verified on the selected network.

Common mistakes and risks

When message signing is involved, separate display data from on-chain facts. Names, icons and fiat estimates may come from external data sources, while balances, transaction state and approvals should be verified on the selected network.

For transaction signing, retain the transaction hash or other useful reference when appropriate. On-chain transactions generally cannot be reversed unilaterally by a wallet, which makes pre-broadcast checks of the address, network, amount and permissions especially important.

Build a repeatable decision process

For transaction signing, retain the transaction hash or other useful reference when appropriate. On-chain transactions generally cannot be reversed unilaterally by a wallet, which makes pre-broadcast checks of the address, network, amount and permissions especially important.

Finally, consider approval management. Third-party DApps, smart contracts and network services can introduce technical, operational and market risk. Unclear signatures, unnecessarily broad approvals, or any page asking for a seed phrase or private key are reasons to stop and re-check the request.
