Arbitrage One, Ethereum’s optimistic second-layer rollup, surpassed 1 billion transactions this week.

It took the network three years to reach this milestone since its launch in August 2021.

According to Arbiscan, there have been 1.003 billion transactions as of October 1.

By comparison, Coinbase’s second-layer network, Base, has seen 755 million transactions, while the OP Mainnet has seen 347 million.

Arbitrage One also leads the way in total value locked (TVL) among layer-2 solutions, with $14.3 billion, while Base has $7.32 billion and the OP Mainnet has $6.57 billion.

Last month, stablecoin issuer Paxos announced plans to launch its products on Arbitrage One to further institutional integration and bring real-world assets to the blockchain.
