$USDC Arbitrum is a rollup chain designed to improve the scalability of Ethereum. It achieves this by bundling multiple transactions into a single transaction, thereby reducing the load on the Ethereum network.
In simple terms, a rollup chain is a layer 2 solution that aggregates and processes transactions off-chain, before submitting a single transaction to the Ethereum mainnet. This means that users can enjoy faster and cheaper transactions, while still benefiting from the security and decentralization of the Ethereum network.
Arbitrum's native token is called the Arbitrum token, or ARB for short. The token is used to pay for transaction fees on the Arbitrum network and also serves as a means of governance for the protocol. Holders of ARB can participate in decision-making processes, such as proposing and voting on protocol upgrades or changes.
Arbitrum is a rollup chain that enables faster and cheaper transactions on Ethereum, while its native token ARB is used for transaction fees and governance. With the increasing demand for Ethereum-based applications and transactions, rollup chains like Arbitrum are becoming increasingly important for improving the scalability of the network.
