Tether has launched USDT on the Bitcoin mainnet using the Taproot Assets protocol, marking the first time the world’s largest stablecoin has been issued natively on Bitcoin’s base layer. The deployment enables instant, low-fee USDT transfers secured by Bitcoin’s proof-of-work without requiring a separate blockchain or bridge.
Developed by Lightning Labs, Taproot Assets leverages Bitcoin’s Taproot upgrade to embed asset metadata directly in transaction outputs. Unlike prior attempts such as Omni Layer or RGB, Taproot Assets uses a client-side validation model where asset transfers are verified by the receiver rather than by a global consensus layer, preserving Bitcoin’s block space efficiency.
“This is the moment stablecoins become a native Bitcoin primitive,” said Paolo Ardoino, CEO of Tether. “For years, USDT has lived on Ethereum, Tron, and Solana. Now it lives on the most secure, decentralized settlement layer in existence. No bridges, no wrapped tokens, no counterparty risk beyond Tether’s reserves.”
The initial deployment mints 100 million USDT on Bitcoin, with Tether committing to maintain 1:1 redemption through its existing reserve attestation framework. Users can send and receive Taproot USDT using compatible wallets including Leather, Xverse, and the Lightning Labs reference implementation. Transactions settle in approximately 10 minutes — Bitcoin’s block time — with fees currently under $0.50.
Lightning Labs CTO Olaoluwa Osuntokun emphasized that Taproot Assets is not limited to stablecoins. “The protocol supports any asset type: tokenized equities, real estate, carbon credits, even other cryptocurrencies. USDT is just the first major issuance. We expect dozens of asset types to launch on Bitcoin in the coming quarters.”
The move positions Bitcoin as a direct competitor to smart contract platforms for stablecoin settlement. Ethereum currently hosts over $100 billion in stablecoin supply, while Tron processes more daily USDT transactions than any other chain. Taproot Assets offers a credible alternative: Bitcoin’s censorship resistance and 99.99% uptime without the complexity of Layer 2 ecosystems.
Market reaction was immediate. USDT’s market capitalization rose $200 million within hours of the announcement, suggesting new demand for Bitcoin-native dollar exposure. Bitcoin’s price climbed 2.3% to $106,500, while Lightning Network capacity grew 4% as users opened channels to test the new asset.
Regulatory questions remain. The U.S. Treasury’s Office of Foreign Assets Control has not yet issued guidance on Taproot Assets, and the SEC’s stance on Bitcoin-native stablecoins under the incoming Atkins administration is uncertain. Tether has faced scrutiny over reserve transparency in the past, though its quarterly attestations from BDO Italia have consistently shown adequate backing.
Competitors are watching closely. Circle, issuer of USDC, has not announced plans for a Bitcoin-native deployment but has researched similar technologies. Meanwhile, the Bitcoin-based stablecoin protocol Stably launched USDS on Taproot Assets last month, though with only $5 million in circulation.
