Tether's USDT0 Deploys on Bitcoin Sidechain Rootstock

Tether’s USDT0 stablecoin is now operational on the Rootstock Bitcoin sidechain.

Rootstock Integrates Tether’s Omnichain USDT0

The integration makes the omnichain version of USDT accessible natively on Rootstock through Layerzero’s OFT standard. Rootstock combines Bitcoin’s proof-of-work (PoW) security via merged mining with Ethereum Virtual Machine compatibility.

Rootstock’s infrastructure includes the PowPeg two-way Bitcoin bridge, block times averaging 20-25 seconds, and the RIF Services Layer for cross-chain functions. Existing protocols on the network include Sovryn, Tropykus, Midas, and Mynt, supporting activities like Bitcoin-backed loans.

According to the announcement on Tuesday, USDT0 deployment aims to enable the stablecoin to move natively across chains without external bridges or wrapped assets. The goal is to consolidate liquidity and reduce transaction friction for users and applications operating on Rootstock.

“USDT0 moves natively across chains and apps, removing fragmentation and powering deeper liquidity on DEXs,” the Rootstock.io blog states.

The addition brings the popular dollar-pegged asset into the Rootstock ecosystem. For builders, it unlocks greater composability for decentralized apps; for users, it could mean tighter trading margins. Tether stands as the largest stablecoin by market cap, boasting a hefty $160 billion valuation today.

Beyond Rootstock, tether is integrated across nearly 100 blockchains, both in native and bridged formats. USDT0 can be routed to Rootstock through its dedicated portal. This version—Tether’s USDT0—is the omnichain, streamlined edition of USDT, built to glide effortlessly across multiple networks.
