Prepare before you start
Before using this web3 & dapp guide guide, identify the account, network, asset, and exact outcome you want. Similar-looking addresses do not make two networks interchangeable, and a wallet interface cannot automatically correct a transfer that was sent on the wrong chain; in Web3 & DApp Guide, read this specifically alongside “Prepare before you start” and DApp connections. A clear task definition makes every later check more meaningful; in Web3 & DApp Guide, read this specifically alongside “Prepare before you start” and DApp connections. For Web3 & DApp Guide, connect DApp connections with domain verification and account requests; the important part is the relationship between those concepts and the on-chain evidence you can verify afterward.
Understand DApp connections and domain verification
Start by understanding how DApp connections and domain verification affect the operation. Do not rely on a default network or an autofilled address for a high-value action; in Web3 & DApp Guide, read this specifically alongside “Understand DApp connections and domain verification” and domain verification. Confirm the network, destination, token contract when relevant, and the account that will sign; in Web3 & DApp Guide, read this specifically alongside “Understand DApp connections and domain verification” and domain verification. For a first-time workflow, a smaller test can help you understand the sequence, but the same checks are still required; in Web3 & DApp Guide, read this specifically alongside “Understand DApp connections and domain verification” and domain verification. When working through “Understand DApp connections and domain verification,” check the source, network, request details and resulting state in that order, with extra attention to domain verification and account requests.
- Confirm the intended account and network.
- Verify the address, contract or DApp independently.
- Know what will change after the request is confirmed.
Work through account requests and signatures carefully
When you reach account requests and signatures, read what the wallet is actually asking you to approve. A DApp connection is not blanket consent for later signatures; in Web3 & DApp Guide, read this specifically alongside “Work through account requests and signatures carefully” and account requests. If a contract, permission, amount, or destination differs from what you expected, cancel the step and restart from a trusted entry point instead of trying to “fix” an unclear request in place; in Web3 & DApp Guide, read this specifically alongside “Work through account requests and signatures carefully” and account requests. Do not treat an interface success message as the final answer for Web3 & DApp Guide. Use account requests, signatures and approvals to confirm that the expected change occurred on the intended network.
Verify the on-chain result
After submission, verify the result with the transaction hash rather than trusting only a success toast; in Web3 & DApp Guide, read this specifically alongside “Verify the on-chain result” and signatures. The explorer should show the network, sender, recipient, fee, status, and confirmation progress; in Web3 & DApp Guide, read this specifically alongside “Verify the on-chain result” and signatures. For steps involving approvals, the process may include waiting periods or multiple stages, so the first wallet notification is not always the final on-chain state. If “Verify the on-chain result” is unclear, stop before approving and return to the basics of signatures and approvals, then verify the result with a transaction hash, contract address or block record where applicable.
Troubleshooting common mistakes
Common mistakes include the wrong network, a copied address error, an incorrect token contract, insufficient gas, duplicate submissions, and confusing a connection request with a transaction; in Web3 & DApp Guide, read this specifically alongside “Troubleshooting common mistakes” and approvals. Troubleshoot in a fixed order: network, address, transaction hash, contract, then current status; in Web3 & DApp Guide, read this specifically alongside “Troubleshooting common mistakes” and approvals. If disconnecting sessions looks unusual, first establish whether a transaction was actually broadcast; in Web3 & DApp Guide, read this specifically alongside “Troubleshooting common mistakes” and approvals. A durable routine for Web3 & DApp Guide is to make approvals a first-pass check, use disconnecting sessions as a second check, and rely on verifiable information related to DApp connections rather than interface assumptions.
Good habits after the task is complete
Once the task is complete, disconnect DApps you no longer need and review approvals that may remain active; in Web3 & DApp Guide, read this specifically alongside “Good habits after the task is complete” and disconnecting sessions. Keep seed phrases and private keys offline and never send them through screenshots, cloud notes, or support chats; in Web3 & DApp Guide, read this specifically alongside “Good habits after the task is complete” and disconnecting sessions. Interfaces can change over time; a repeatable verification routine is more reliable than memorizing where a button used to be; in Web3 & DApp Guide, read this specifically alongside “Good habits after the task is complete” and disconnecting sessions. This part of Web3 & DApp Guide should be read together with the surrounding workflow: disconnecting sessions affects how you interpret DApp connections, while domain verification helps confirm the state after the action.
Security and risk reminder
Seed phrases and private keys are controlled by the user. imtoken will never ask for them. Blockchain transactions are generally irreversible by a wallet provider, and third-party DApps, smart contracts, network conditions and digital-asset prices can introduce additional risk.
