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. A 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%. Source: Superchain Health Dashboard
