Tether has launched USDT0, a crosschain US-dollar stablecoin, on the OP mainnet of Optimism’s Superchain, enhancing accessibility within Ethereum’s layer-2 environment.

USDT0’s deployment aims to broaden the use of Tether’s USDT across multiple blockchains, with significant growth expected this year, reflecting in substantial transaction volume.

As of March 2025, Superchain secures approximately 4.2 billion USD and dominates Ethereum L2 transactions, currently holding 52% share.
