About Arbitrum

What Is Arbitrum?

Arbitrum (ARB) is a Layer 2 blockchain built on top of Ethereum that makes transactions faster and cheaper — without giving up Ethereum’s security.

Launched in 2021 by a company called Offchain Labs, Arbitrum was one of the first successful solutions to tackle Ethereum’s biggest challenge: high fees and network congestion.

It’s like adding an express lane to Ethereum’s busy highway — users still get where they’re going, just faster and for a fraction of the cost.

⚙️ How It Works

Layer 2 Scaling: Arbitrum processes transactions off the main Ethereum chain, then sends the final result back to Ethereum for security and verification.

Rollups: It bundles (or “rolls up”) hundreds of transactions into one, drastically cutting down costs and network load.

Smart Contract Compatibility: Developers can use Arbitrum without rewriting their Ethereum code — everything just runs faster and cheaper.

The result? Smooth DeFi trading, NFT minting, and blockchain gaming with minimal gas fees.

💰 ARB — The Native Token

The ARB token launched in 2023 and is used for:

Governance: ARB holders can vote on key proposals that guide the future of the Arbitrum ecosystem.

Ecosystem Funding: Tokens support new projects and community development on the network.

Unlike some tokens, ARB isn’t required for transaction fees — those are still paid in ETH — but governance makes it essential for decision-making and coordination.

🌍 Why It Matters

Ethereum is powerful, but scaling it for millions of users has been a long-term challenge.

Arbitrum provides a real, working solution — improving transaction speed, reducing fees, and keeping Ethereum usable for regular people and developers alike.

It’s also home to a thriving DeFi ecosystem, including major apps like Uniswap, Aave, and GMX, all running smoothly on Arbitrum’s high-performance Layer 2 environment.
