What Is Arbitrum (ARB)?

Arbitrum is the largest Ethereum Layer 2 rollup by total value locked and transaction volume. It uses optimistic rollup technology to batch transactions off-chain and submit proofs to Ethereum, achieving faster speeds and lower fees while inheriting Ethereum's full security.

Why Arbitrum matters:

• Dominant L2: Arbitrum holds more TVL than any other rollup — over $2.5B in DeFi protocols like GMX, Camelot, and Radiant.

• True Ethereum security: all transactions ultimately settle on Ethereum's Layer 1, making Arbitrum as secure as the mainnet.

• Orbit chains: Arbitrum's tech lets anyone launch their own L3 (app-chain) using Arbitrum's stack, creating a multi-rollup ecosystem.

💡 Tip: ARB is a governance token with 10B max supply — heavy inflation is a concern. Consider it as a utility bet on L2 growth rather than a scarce asset like BTC or ETH.

What's an optimistic rollup? +
An optimistic rollup assumes transactions are valid by default (optimistic) and only checks them if someone challenges them. This is faster than ZK rollups (which prove validity upfront) but has a 7-day withdrawal delay for fraud challenges. Arbitrum uses this approach for maximum throughput.
Is ARB token inflationary? +
Yes. ARB has a 10B max supply, with roughly half still unlocked. Tokens are distributed to the Arbitrum DAO treasury, team, investors, and users over several years. This ongoing dilution means ARB's price can struggle even as the network grows — value accrues to the network, not necessarily the token.
Arbitrum vs Optimism — which is better? +
Arbitrum has more TVL and DeFi activity. Optimism has the Superchain vision (shared L2 infrastructure) and more brand partnerships (Base, Zora). Both are strong; Arbitrum is the practical leader today, while Optimism has the more ambitious long-term ecosystem strategy. They're complementary, not mutually exclusive.
How do I use dApps on Arbitrum? +
Switch your MetaMask or Rabby wallet to the Arbitrum network (automatically configured in most modern wallets). Bridge ETH from mainnet to Arbitrum via the official bridge at bridge.arbitrum.io. Once you have ETH on Arbitrum, you can use any dApp — GMX for perpetuals, Camelot for swaps, Radiant for lending.
