Tether brings USDT back to Bitcoin with private transfers and swaps

Tether's USDT stablecoin is returning to the Bitcoin network in October 2026 through Utexo, a Tether-licensed infrastructure project that raised $7.5 million. Utilizing the RGB protocol and Bitcoin's UTXO model, Utexo will enable private transfers, direct BTC-USDT swaps, and native Bitcoin-backed loans. To maintain compliance without account-freezing capabilities, Utexo will blacklist illicit UTXOs. Over 450 businesses have expressed interest in the launch, which plans to expand to the Lightning Network.

USDT Bitcoin network return

• ▪USDT originally launched in 2014 on the Omni Layer protocol built on Bitcoin, but Tether shifted primary issuance to Ethereum and Tron before halting Omni issuance in August 2023
• ▪Utexo, founded in 2025, raised $7.5 million in early 2026 and holds a commercial license from Tether to issue USDT on the Bitcoin network

RGB protocol privacy architecture

• ▪Utexo's architecture combines the RGB protocol and Bitcoin's UTXO model to enable private USDT transfers, direct BTC-USDT swaps, and loans backed by native Bitcoin
• ▪The RGB protocol uses client-side validation to keep transaction details off-chain between counterparties, using Bitcoin's ledger solely to cryptographically demonstrate proof of ownership

Tether Bitcoin treasury holdings

• ▪Tether holds approximately 100,000 Bitcoin, valued at around $8.4 billion as of mid-August 2026, according to Bitcoin Treasuries
• ▪Utexo co-founder Viktor Ihnatiuk stated that Tether views Bitcoin as a stability haven alongside gold, which is why the company continues to purchase Bitcoin and support the community

Lightning Network expansion plans

• ▪Utexo aims to potentially make USDT a token for paying transaction fees on Bitcoin's Lightning Network, similar to USDC's use on the Arc network
• ▪Following Utexo's initial launch of USDT on Bitcoin's mainnet, Utexo plans to extend USDT support to Bitcoin's Lightning Network to enable faster and cheaper payments

Debatable claims

• ▪Blacklisting UTXOs on Bitcoin compromises the network's censorship resistance
• ▪Utexo's UTXO-blacklisting model is an effective way to police illicit stablecoin transactions
• ▪Native Bitcoin-backed loans are safer than using wrapped tokens like WBTC
• ▪Keeping stablecoin transaction details off-chain poses unacceptable illicit finance risks
