The Arbitrum Network, Explained
Quick answer
Arbitrum One is the largest Ethereum Layer 2, live since 2021. It executes transactions in fractions of a second for cents, then posts compressed batches to Ethereum, inheriting its security. ETH pays gas on Arbitrum; ARB is the separate governance token of the ecosystem.

Network fee: Typically $0.01–$0.10 per transaction in 2025–2026, since the Dencun upgrade gave rollups cheap blob data on Ethereum. Third-party network figures, not Anytime Capital pricing — our pricing is on the fees & limits page.
How long does a Arbitrum transfer take?
Arbitrum sequences transactions in fractions of a second, so transfers feel instant. Exchanges typically credit deposits within minutes once the batch posts to Ethereum. The famous 7-day delay applies only to withdrawing through the official bridge back to Ethereum L1 — normal transfers and exchange routes never wait that long.

How does a Layer 2 like Arbitrum work?
Arbitrum runs its own fast execution environment, then periodically posts compressed transaction batches to Ethereum, where they become as hard to reverse as Ethereum itself. That's the 'rollup' model: Ethereum provides the security and data availability; Arbitrum provides speed and cent-level fees. Since Ethereum's March 2024 Dencun upgrade gave rollups dedicated blob space, Arbitrum fees have sat around pennies.
For consumers, it behaves like a cheaper, faster Ethereum with the same addresses and tokens — with the one rule that applies to every EVM network: the network selector at withdrawal decides where funds land.
Does the 7-day withdrawal delay affect me?
Almost never. Optimistic rollups impose a challenge window (about 7 days) only on withdrawals through the canonical bridge back to Ethereum L1. Everyday activity — transfers on Arbitrum, exchange deposits and withdrawals, fast third-party bridges — doesn't touch that path. Exchanges credit Arbitrum deposits in minutes and send Arbitrum withdrawals directly on the L2.
ETH vs ARB on Arbitrum — which pays for what?
This trips people up: gas on Arbitrum is paid in ETH, not ARB. ARB is the governance token of the Arbitrum DAO — an investable asset with a vote attached, not the network's fuel. A wallet on Arbitrum therefore needs a small ETH balance to transact, even if it holds plenty of ARB.
