Arbitrum’s Speed Unlocked in MetaMask

Arbitrum is a Layer 2 scaling solution that addresses Ethereum’s scalability challenges. As of May 2024, it holds approximately $16 billion in TVL and accounts for about 40% of the Ethereum Layer 2 market share. Compared to Ethereum mainnet’s 20–40 TPS, it achieves processing speeds of up to 40,000 TPS, significantly reducing gas fees.

MetaMask, the leading web3 wallet with over 100 million users, functions as an arb wallet, providing seamless access to the Arbitrum ecosystem. Arbitrum’s two-layer structure, consisting of off-chain processing and mainnet recording, is supported by optimistic rollup technology, enabling users to enjoy low-cost and high-speed transactions.

Expansion of the Arbitrum Ecosystem

The Arbitrum network currently hosts about 250 dApps, including DeFi platforms, NFT marketplaces, and gaming applications. It is chosen as an efficient and cost-effective blockchain solution for both developers and users.
