Arbitrum - ARB

Arbitrum is a Layer 2 network built on top of Ethereum that makes using Ethereum faster and cheaper, without giving up any of the security.

In simple terms: Arbitrum takes your Ethereum transactions, processes them off-chain in batches, and then posts the results back to Ethereum. You still get Ethereum-level security, but with a huge upgrade in speed and affordability. ARB is the token that powers this ecosystem, it’s used for governance and potentially future utility.

Arbitrum ARB is a Layer 2 built for one mission: make Ethereum scale, without breaking it.

It uses something called optimistic rollups, which batch transactions off-chain and settle them back to Ethereum. That means lower gas fees, higher throughput, and security backed by Ethereum’s base layer. No compromises. No half-measures.

What makes Arbitrum special?

• Fully EVM-compatible – developers don’t have to rewrite a single line of code
• Fast adoption – it’s home to a massive DeFi ecosystem (GMX, Radiant, Camelot, and more)
• No central sequencer lock-in – decentralization is baked into the roadmap
• Stylus – their upcoming upgrade lets devs write smart contracts in languages like Rust and C++

And the numbers speak for themselves: Arbitrum has the highest total value locked (TVL) of any Layer 2, period. More usage, more builders, more users. Arbitrum doesn’t try to be flashy. It just works. And in crypto, that’s power.

Arbitrum is a Layer 2 scaling solution for Ethereum that uses a technique called Optimistic Rollups.

Here’s what that means:

• It batches many transactions off-chain
• Posts a summary of the result back to Ethereum
• Assumes transactions are valid unless someone challenges them (hence “optimistic”)
• Keeps the cost low while still relying on Ethereum’s security

It’s smart, fast, and battle-tested. Arbitrum handles the traffic jam so Ethereum can keep moving.

Ethereum is powerful, but it wasn’t built for speed or low fees. Arbitrum steps in to solve that.  By moving most transaction processing off-chain and syncing only the results to Ethereum, Arbitrum:

• Slashes gas fees
• Increases throughput
• Keeps apps EVM-compatible
• Makes Ethereum usable for DeFi, NFTs, and everyday users

It’s not a competitor, it’s a collaborator. And with huge adoption across major dApps, Arbitrum is one of Ethereum’s most important scaling allies.
