FAQ
Review the questions that most often appear when users work with wallets, blockchain networks, DApps, approvals, and validators.
It helps users manage multi-chain digital assets, review on-chain activity, and connect with Web3 applications. Users should still understand networks, addresses, gas, signatures, and approvals before acting.
A private key controls a specific account, while a seed phrase can commonly derive a set of accounts. Both are highly sensitive and should remain under the user’s control.
The same asset can exist on multiple networks and addresses can look similar. Verify the destination network, address, and asset type together before sending.
Gas measures the computational resources needed for an on-chain action. Fees vary with network conditions, transaction complexity, and fee parameters.
A transaction hash identifies a specific on-chain transaction and can be used with the matching network explorer to inspect status, block height, confirmations, and execution results.
Check network congestion and fee settings, then inspect the transaction hash on-chain. Avoid repeatedly sending duplicate transactions simply because confirmation is taking time.
Not necessarily. A connection may only expose an account for interaction. Signatures, transactions, and token approvals are separate requests and should be reviewed separately.
A message signature proves that an account approved a piece of data. It may not directly move assets, but malicious signatures can still be used for authentication or permissions.
A token approval allows a contract to act on a specified token up to an allowed amount. Review the contract address, target, and allowance, and consider revoking permissions you no longer need.
It increases the potential scope of exposure, but context matters. Understand the contract and limit or revoke allowances when appropriate.
Many EVM networks share similar address formats and contract models, but they are still separate networks with different chain IDs, gas assets, state, and token contracts.
Layer 2 systems typically move part of execution away from the base layer while relying on a settlement or data publication relationship. Cross-layer transfers may require a bridge and waiting time.
Verify the domain and how you reached it. Be cautious with search ads, chat links, and fake support. Any webpage asking for a seed phrase, private key, or verification code should be treated as unsafe.
Use caution. Public networks may increase exposure to rogue hotspots or traffic manipulation. Sensitive actions are better performed on a trusted network and controlled device.
No. Rewards can change, exits may involve waiting, validators can face network penalties, and digital asset prices can fluctuate.
Validators participate in protocol duties such as block proposals or attestations. Responsibilities and reward mechanisms depend on the network, and downtime or protocol violations can lead to penalties.
No. Seed phrases and private keys are controlled by the user. Official staff will not request them and cannot promise to recover a lost private key.
Stop before confirming. Record the domain, contract address, and request details, disconnect unnecessary sessions, and review existing approvals with reliable tools.
