USDT0 launches on OP Superchain amid stablecoin growth

Crosschain stablecoin USDT0 (CRYPTO:USDT0) has expanded its reach by deploying on Optimism’s (CRYPTO:OP) Superchain network, enhancing accessibility to Tether’s (CRYPTO:USDT) USDT across Ethereum’s (CRYPTO:ETH) layer-2 ecosystem.

The integration, announced March 27, follows USDT0’s initial launch on Kraken’s DeFi-focused layer-2, Ink, in January.

Superchain, a collective of Ethereum (CRYPTO:ETH) layer-2 chains using Optimism’s OP Stack, currently handles over 50% of Ethereum L2 transactions and is projected to reach 80% dominance by year-end, according to Optimism Chief Growth Officer Ryan Wyatt.

The network’s total value locked (TVL) has grown to $4.2 billion, up from $4 billion in February.

USDT0’s deployment aims to attract “more top-tier assets, applications and partners” to Superchain, leveraging stablecoins’ role in driving DeFi adoption.

Globally, stablecoins in circulation now total nearly $228 billion, with Ethereum hosting 58% of supply.

Tether’s USDT remains the most widely used stable asset, supported by its first-mover advantage and significant U.S. Treasury holdings.

The integration aligns with broader regulatory shifts under the Trump administration, where dollar-pegged stablecoins are gaining policy traction.

Bo Hines, head of Trump’s digital assets council, recently indicated comprehensive stablecoin regulations could reach the president’s desk within two months.

While Superchain’s growth underscores Ethereum L2 scalability, challenges persist in balancing crosschain interoperability with regulatory compliance.

USDT0’s expansion highlights stablecoins’ evolving role in bridging traditional finance and decentralised systems, though adoption hurdles remain tied to infrastructure maturity and policy clarity.

At the time of reporting, the USDT0 price was $1.00, and the Optimism (OP) price was $0.8706.
