Wallets and recovery information

What is a wallet address?

A wallet address is a public on-chain identifier used to receive assets or identify an account. Before sending, verify that the recipient address matches the intended network.

How are seed phrases and private keys different?

Both can provide control or recovery capability. A seed phrase commonly derives multiple accounts, while a private key corresponds to a specific cryptographic key. Keep both private and never send them to anyone.

Why can the same address show different assets on different networks?

Networks maintain separate ledgers. Even when address formats look similar, balances, token contracts, and transaction history are recorded independently on each network.

What is gas?

Gas is a way to measure the computational or network resources used by an on-chain action. The resulting fee depends on network rules, transaction complexity, and current conditions.

What is a transaction hash used for?

A transaction hash is a key identifier for locating an on-chain transaction in the relevant block explorer and checking its status, block, and confirmations.

Can a blockchain transaction be reversed?

Once confirmed, a blockchain transaction generally cannot be reversed unilaterally by a wallet. Verify address, network, asset, and amount before sending.

Does connecting to a DApp automatically transfer assets?

A connection by itself generally is not a transfer, but a DApp may later request signatures, transactions, or token approvals. Review each request separately.

Are message signatures and transaction signatures the same?

No. A message signature can express authorization over data, while a transaction signature typically authorizes an executable on-chain action. Review the origin and meaning of both.

What is a token approval?

An approval lets a specified smart contract use a token within granted permissions. It is not an immediate transfer, but excessive or stale permissions can create risk.

Why do EVM networks use similar address formats?

EVM-compatible networks often use similar account models and address formats, but chain IDs, gas assets, contracts, and ledgers remain distinct. Always verify the network.

DApps, signatures, and approvals

How does Layer 2 relate to a base layer?

Layer 2 systems process additional activity and connect back to a base layer through network-specific security or settlement mechanisms. Cross-layer transfers can have separate steps and waiting periods.

How can I recognize phishing?

Check the domain, how you reached the page, whether it creates urgency, whether it asks for recovery secrets, and whether signature or approval requests match your intended action.

Will official support ask for my seed phrase?

No. A seed phrase, private key, recovery phrase, or verification code should never be sent to anyone or entered into a support form.

What is Ethereum proof of stake?

Ethereum uses proof of stake to organize validator participation in consensus. Staking, validators, rewards, and exits are affected by protocol rules and network state.

Does staking guarantee returns?

No. Rewards can change, exits can take time, validators can face penalties, smart contracts and third-party services can carry risk, and digital asset prices can fluctuate.

Security, Ethereum, and validators

Why can validators be penalized?

Proof-of-stake networks can penalize validators for specific behavior or failures defined by protocol rules. The impact depends on the network and the event.

What should I check when a transfer looks wrong?

Start with the selected network, public address, transaction hash, and block-explorer status. Then determine whether the transaction is pending, failed, on another network, or simply not displayed correctly.

How can I reduce long-term approval risk?

Review DApp and token approvals periodically, verify approval targets and allowances, and consider revoking permissions that are no longer needed.
