What is Arbitrum?
Arbitrum is one of the largest Ethereum layer-2 networks. It delivers Ethereum-grade security with very low fees using the same ERC-20 standard and wallets — popular for DeFi and affordable token launches.
Arbitrum in a nutshell
Arbitrum is a layer-2 that runs on top of Ethereum using "optimistic rollup" technology. It processes transactions cheaply off-chain and settles them on Ethereum. It uses ETH for fees and the ERC-20 standard.
How Arbitrum works
Arbitrum bundles many transactions and posts them to Ethereum, assuming they are valid unless challenged (hence "optimistic"). This gives you the same tokens and MetaMask wallet at a small fraction of Ethereum's gas.
Why Arbitrum for tokens
- Very low fees — cents per transaction.
- Large DeFi ecosystem — deep liquidity and many apps.
- Same ERC-20 tooling — MetaMask, Uniswap, Camelot.
- Ethereum security at L2 cost.
Arbitrum vs Base
Both are top Ethereum L2s. Arbitrum has a more established DeFi scene; Base has Coinbase's mainstream reach. See Base vs Arbitrum.
Getting started on Arbitrum

Frequently asked questions
Is Arbitrum a separate chain from Ethereum?

No — it is EVM-compatible. MetaMask works; just add the Arbitrum network.
How much does a token cost on Arbitrum?
Just cents of ETH gas plus a flat service fee — much cheaper than Ethereum mainnet.
