Tether has launched its crosschain US-dollar stablecoin, USDT0, on Optimism's Superchain, enhancing accessibility to its stable asset within Ethereum’s layer-2 ecosystem. Announced on March 27, USDT0 is now live on the OP mainnet, following its initial deployment on Kraken’s DeFi-focused layer-2, Ink. This bridged version of Tether's USDt is designed to expand stablecoin adoption across multiple blockchains, created in cooperation with the interoperability protocol LayerZero. Superchain is a network of layer-2 chains aimed at scaling Ethereum via Optimism’s OP Stack, currently accounting for over half of all Ethereum layer-2 transactions. Tether's move to integrate USDT0 is expected to attract more leading assets and applications, emphasizing the critical role of stablecoins in bolstering DeFi adoption. The total value of stablecoins has surged to nearly $228 billion globally, with Ethereum representing 58% of the total stablecoin supply. Tether remains a dominant player in the stablecoin market, significantly bolstered by its holdings of US Treasury assets.
