Wallet basics
When troubleshooting wallet basics, keep verifiable details such as the transaction hash, destination address, selected network and contract address. Do not send a seed phrase or private key. On-chain transactions generally cannot be reversed by the wallet alone, so careful checks before submission are more reliable than hoping for recovery later.
When working with wallet basics, separate what the interface displays from what the blockchain actually records. The wallet helps you review and initiate actions, while the final state depends on the target network, transaction data and block confirmations. Before any asset movement or permission change, confirm the counterparty, network and intended result before signing.
A durable habit around wallet basics matters more than memorizing where a button sits. Interfaces may change across devices or versions, but addresses, networks, transaction hashes, contract addresses and approval targets remain verifiable. When something looks wrong, use those facts to distinguish a display issue from network congestion or a contract interaction problem.
How to verify information about Wallet basics
Prioritize fields that can be independently checked for Wallet basics. Compare the state before and after the action; if the result differs from what you expected, verify the network and transaction state before taking further action.

Risk around network basics often comes from incomplete information or confusing one object for another. Lookalike domains, same-name tokens, the wrong network or an unnecessarily broad approval can all produce a normal-looking screen while leading to an unintended action. Reduce that risk by checking critical fields one by one instead of relying on a single badge or visual cue.

- Confirm the network or counterparty relevant to Network basics
- Keep the transaction hash or contract address related to Network basics
- Never send a seed phrase, private key or verification code
Transaction basics

Reduce that risk by checking critical fields one by one instead of relying on a single badge or visual cue.
From a learning perspective, transaction basics is not isolated. It connects to account control, network selection, gas, confirmations, DApp permissions and block explorer data. Seeing those relationships makes it easier to understand the full lifecycle of an on-chain action from creation and signing to broadcast and confirmation.
