ERC-20 tokens live on Ethereum smart contracts. Your wallet app reads token balances from the blockchain and shows them in your portfolio view.
When a token does not appear automatically, you may need to add the token contract address. Only use official contract addresses from trusted sources to avoid fake tokens.
For sending tokens, you pay gas in ETH. Keep a small ETH balance available so you can move ERC-20 assets when needed.
Key actions you can expect from a modern ETH wallet app: create addresses, sign transactions, display balances, and help you review what you approve when interacting with smart contracts.
Practical safety reminders: verify addresses, keep the recovery phrase offline, and do not approve unknown contract requests. Small checks reduce large mistakes.
What is an ETH wallet app? An ETH wallet app is a wallet interface that lets you create addresses, sign transactions, send and receive ETH, and manage Ethereum-based assets such as ERC-20 tokens and NFTs.
Is an ETH wallet app free? Many wallet apps can be installed for free. Network fees (gas) are paid to the Ethereum network when you send transactions or interact with smart contracts.
How do I create an Ethereum wallet? Generate a new wallet, write down the recovery phrase, verify it, and then fund your address to start sending, receiving, or using Web3 apps.
