What is Arbitrum and How Does an Arbitrum Wallet Work?
Developed by Offchain Labs, Arbitrum is a Layer-2 scaling solution for Ethereum designed to enhance scalability and reduce transaction costs. Founded by computer science experts—Edward Felten, Steven Goldfeder, and Harry Kalodner—Arbitrum leverages Optimistic Rollup technology to process transactions off-chain while maintaining Ethereum’s security.
An Arbitrum wallet securely stores ETH and tokens (ERC-20/ERC-721) on the Arbitrum network. Think of it as a bank account where:
- Your wallet address acts as the account number.
- A secret passphrase serves as your password.
- Transactions remain pseudonymous (only the address is visible).
