Getting started on Arbitrum
Arbitrum is built by Offchain Labs, which consists of world-class engineers, researchers, and Ethereum experts. Arbitrum One main-net launched on the 31st of August 2021 and serves as an optimistic layer-2 rollup on Ethereum.
Arbitrum uses ETH to pay for transactions, and you will also need USDT to participate in the Narwhal ecosystem, either as a liquidity provider or trader.
If you don't have any assets on Arbitrum, you can transfer funds from other layer 1 blockchains using the following bridges:
Official Arbitrum Bridge (Ethereum to Arbitrum): https://bridge.arbitrum.io/
