About Arbitrum
Arbitrum is a set of Ethereum L2 scaling technologies developed with the Arbitrum Nitro tech stack (upgraded as of late to Arbitrum Stylus), comprising Arbitrum One and Arbitrum Nova. Although Ethereum is the first cryptocurrency to enable Turing-complete stateful smart contracts, both its scalability and anonymity are constrained, which is why the Arbitrum suite was created in response to these developer pain-points.
Arbitrum One is the first Arbitrum Rollup Chain deployed on the Ethereum mainnet and is now available on Blast. It is completely trustless, inheriting Ethereum's base-layer security guarantees without adding new trust assumptions.
Arbitrum One is an excellent option for decentralized banking and other applications requiring L1-level trustlessness. Arbitrum One was launched publicly in 2021. Shortly after its deployment, prominent Ethereum protocols like Uniswap, Curve, Aave, and Sushi implemented their smart contracts on Arbitrum One. On August 31, 2022, the network underwent a significant upgrade to the Nitro stack, enhancing throughput and reducing gas costs. Arbitrum public endpoints for both Mainnet and Testnet are available in Blast API.
