USDT0 deploys on OP Superchain
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. It launched within the Tether ecosystem independently in January, with support from Tether and its CEO, Paolo Ardoino.
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.

In February, Optimism Chief Growth Officer Ryan Wyatt told Cointelegraph that Superchain will likely account for 80% of Ethereum L2 transactions this year. At the time, Superchain secured more than $4 billion in total value, which has since grown to $4.2 billion.

Stablecoin adoption heats up
Superchain said deploying USDT0 is expected to attract “more top-tier assets, applications and partners” to the collective, which highlights the role stablecoins play in fueling DeFi adoption.
The total value of all stablecoins in circulation has reached nearly $228 billion, having increased 3.3% over the past 30 days. According to RWA.xyz, there are more than 155 million stablecoin holders worldwide.
Ethereum accounts for 58% of the total stablecoin supply.

Tether has long had a first-mover advantage in the stablecoin market. The company has emerged as one of the world’s largest holders of US Treasury assets, which has helped fuel its record-breaking profits in recent years.
With US President Donald Trump in the White House, dollar-pegged stablecoins have become a major policy driver in the United States.
The head of Trump’s council on digital assets, Bo Hines, recently told a conference in New York that comprehensive stablecoin regulations could arrive on the president’s desk within two months.
