Frequently asked questions
What is Arbitrum One and what are its primary use cases?
Arbitrum One is an Ethereum Layer 2 optimistic rollup (Nitro) that uses ETH as its native currency to deliver low-cost, high-throughput execution while inheriting Ethereum security. Typical fees are about $0.02–$0.20 per simple transaction with sub‑second sequencer confirmations, sustained throughput in the tens to low hundreds of TPS, and activity that often exceeds 1M transactions per day. Primary use cases include cost‑efficient DeFi, NFTs, gaming, high‑frequency trading, and bridging assets to/from Ethereum for faster, cheaper execution.
What makes Arbitrum One unique compared to other blockchain networks?
Arbitrum One is EVM‑equivalent and built on the Nitro stack with multi‑round interactive fraud proofs (BOLD architecture), enabling near drop‑in Solidity tooling and aggressive calldata compression that keeps fees 10–100× lower than Ethereum L1 and competitive with other L2s. It provides sub‑second time‑to‑inclusion from a sequencer, minutes to L1 batch finalization, and a 7‑day challenge window for trust‑minimized withdrawals—trade‑offs distinct from ZK rollups and sidechains. Its large ecosystem, frequent 1M+ daily transactions, and sustained TPS in the tens–hundreds make it a scalable choice for low‑latency, low‑fee applications.
What is the gas token used for Arbitrum One, and how to get it?
Arbitrum One uses ETH as the gas token for transaction fees. You can obtain ETH by bridging from other chains or purchasing using thirdweb Bridge.
