Tether’s crosschain US-dollar stablecoin, USDT0, has been deployed to Optimism’s Superchain, increasing access to the world’s most widely used stable asset across Ethereum’s layer-2 ecosystem. On March 27, Optimism announced that the dollar-pegged USDT0 is now live on the OP mainnet. The crosschain stablecoin’s first deployment was on Ink, Kraken’s DeFi-focused layer-2. USDT0 is essentially a bridged version of Tether’s USDt ( USDT ) designed to extend the stablecoin’s adoption across various blockchains. Tether launched USDT0 in January in collaboration with the interoperability protocol LayerZero. One month later, Tether selected Arbitrum as the main infrastructure provider for USDT0. Superchain is a network of layer-2 chains designed to scale Ethereum through Optimism’s OP Stack. The collective currently accounts for 52% of Ethereum layer-2 transactions, according to data tracked by Superchain. Since September, Superchain’s L2 dominance has grown from 36.6% of all transactions to 51.9%.

At the time, Superchain secured more than $4 billion in total value — a figure that has since grown to $4.2 billion.
