FAQ
A practical guide to wallets, networks, gas, DApps, approvals, security, Ethereum, PoS, and validators, with clear decision points and risk boundaries.
What is a digital wallet?
A digital wallet manages keys, addresses, and requests for on-chain actions. It is not the same as a bank account, and users are responsible for protecting recovery material.
Why is a seed phrase important?
A seed phrase can typically restore control of wallet keys. Anyone who obtains it may gain control of related assets, so keep it offline and never send it to anyone.
Should I give a private key to support?
No. Official staff will not ask for a private key, seed phrase, or verification code.
Why verify the network?
Similar address formats can appear on different networks while assets, gas tokens, and contracts differ. Both sides of a transfer should use the intended network.
What is gas?
Gas represents the resources required to execute an on-chain action. Pricing and mechanics vary by network, and congestion can affect cost and confirmation time.
What is a transaction hash for?
A transaction hash is a key reference for checking an on-chain transaction in the relevant block explorer.
Is connecting to a DApp automatically safe?
No. A connection does not make later signatures, transactions, or approvals safe. Review each request independently.
Are message signatures and transaction signatures the same?
No. A message signature may be used for login or proof of control, while a transaction signature usually authorizes an on-chain state change.
What is token approval?
Token approval lets a specified contract spend tokens within a defined allowance. Review the spender, amount, and whether the approval is still needed.
What do EVM networks have in common?
They share a similar execution model and tooling, but network IDs, gas assets, deployments, and security conditions can differ.
Why does Layer 2 still involve mainnet concepts?
Layer 2 systems often depend on a base layer for settlement, security, or data. Bridging can also involve additional waiting periods and network checks.
How can I reduce phishing risk?
Use trusted entry points, verify domains, reject requests for recovery material, and be cautious with airdrops, support DMs, and remote-control requests.
Does Ethereum staking guarantee returns?
No. Rewards can change, exits may involve waiting, validators can face protocol penalties, smart contracts can fail, and asset prices can move.
What does a PoS validator do?
A validator participates in block proposal and attestation according to network rules and must operate within protocol requirements.
Can an on-chain transaction be reversed?
Usually not by the wallet alone. Once confirmed, an on-chain transfer should generally be treated as irreversible.
How do I confirm an action is complete?
Check the transaction hash, block status, required confirmations, and the resulting balance or approval state rather than relying only on a UI message.
