Ethereum wallets

Meet Ethereum.
Read every approval.

Learn how Ethereum wallets, ETH gas, token approvals, and application connections work, with practical checks for using the right network.

The wallet and the account

An Ethereum wallet is the interface you use to interact with accounts. It can show balances, prepare transactions, and connect with applications. One wallet may manage several accounts, and different wallet interfaces can sometimes access the same account through the same recovery arrangement.

Before choosing one, establish who can authorize activity. Standard key-based accounts, smart accounts, and custodial services can have different recovery and permission models. Understand the specific product instead of assuming every Ethereum wallet works identically.

ETH and tokens have separate roles

ETH pays Ethereum network gas at the protocol level. A token balance does not automatically cover those fees. An application may sponsor a transaction or offer another fee arrangement, but you need to verify that product feature and its limits.

Network fees compensate for computation. A transaction that fails can still use gas, so repeated attempts can cost money without completing the intended action. Read the error and the estimated cost before trying again.

Make network selection deliberate

Ethereum mainnet and other compatible networks can display similar-looking addresses. That does not mean every platform accepts deposits from every network. Confirm the sender's selected network, the receiving service's deposit instructions, and the exact token.

If a route involves a bridge, treat it as an additional system with its own risks and withdrawal process. Do not assume a token is interchangeable solely because the symbol matches.

Connection, approval, and transfer

  • Connection: a website can request access to public account information.
  • Signature: a request may authenticate you or authorize meaningful activity; read its details.
  • Token approval: a contract may receive permission to spend an allowed amount.
  • Transaction: an on-chain action can change balances, permissions, or contract state.

Disconnecting a website does not necessarily remove permissions previously granted on-chain. Review approvals through the wallet's documented tools and understand the network fee before changing them.

A useful everyday routine

Use verified application URLs, keep software current, and review the intended action on the signing screen. Pause if the token, destination, approval amount, or network does not match your intention.
