Tether’s Reintroduction of USDT on Bitcoin
Tether has announced plans to reintroduce its stablecoin USDT as a native asset on the Bitcoin blockchain via the RGB protocol. This significant transition comes after extensive development work spread over eight years, and the launch is anticipated to occur within a matter of weeks.
Collaboration with UTEXO
In an exclusive discussion with Bitcoin Magazine, the company revealed its collaboration with UTEXO—a software firm focused on the integration of the RGB protocol, specifically version v0.11.1—to facilitate the issuance of USDT directly on Bitcoin. This move brings the stablecoin back to its original launch site, where it debuted in 2014 through the Omni-Mastercoin layer.
Commercial efforts for this initiative are spearheaded by UTEXO, which has positioned itself as both the issuer and distributor of the Bitcoin-native USDT. Viktor Ihnatiuk, co-founder of UTEXO, highlighted the years of technological development needed to support this partnership with Tether.
Enhancements through the RGB Protocol
The RGB protocol enhances Bitcoin’s unique UTXO architecture by merging client-side validation with the Lightning Network, allowing users to send and receive USDT via native Bitcoin addresses. This setup not only facilitates instantaneous off-chain transactions through compatible wallets but also bolsters user privacy.
Unlike reusable addresses typical in networks such as Ethereum, Tron, and Solana, transactions on Bitcoin generate new addresses every time, contributing to greater anonymity. Bitcoin Magazine noted that payments routed through the Lightning Network produce fewer imprints on the public blockchain, while the integration between UTEXO and Tether minimizes intermediaries in the stablecoin issuance and transfer process.
Ihnatiuk stressed that the creation of UTEXO aims to ensure USDT moves on Bitcoin seamlessly—emphasizing speed, privacy, and clarity regarding transaction expenses. With the aim of offering businesses increased control over transaction fees, UTEXO has developed a range of tools including APIs, a software development kit, user interface applications, and a mint bridge that simplifies USDT transfers across blockchains with minimized costs, thanks to direct Tether integration.
Anticipated Launch and Market Impact
The anticipated debut of Bitcoin-native USDT is expected to take place soon, likely within July, with various wallets including Tether Wallet gearing up to support this cryptocurrency. Ihnatiuk characterized this transition as a return of USDT to its “home” on Bitcoin, stating that its successful implementation could play a vital role in solidifying Bitcoin’s status as a foundational layer for digital asset transactions.
Historical Context and Future Prospects
The RGB protocol, which has its roots in proposals dating back to 2014, underwent significant delays preventing its readiness during the cryptocurrency boom in 2017. During this period, Tron emerged as the leading platform for USDT transactions, especially in developing markets where a substantial portion of USDT activity persists.
Ihnatiuk elaborated that current users encounter multiple layers of fees when converting between Bitcoin and USDT through various services, which include wallet charges, platform fees, and slippage costs. He advocated for placing both USDT and Bitcoin on a singular settlement infrastructure via the Lightning Network, indicating this could lead to nearly instantaneous trades devoid of the typical third-party fees.
In contrast to existing Tron users, who often have to hold TRX tokens specifically for network fees—which complicates transactions—operating USDT directly on Bitcoin eliminates the necessity of a separate fee token by leveraging Bitcoin’s proven security framework.
The RGB protocol has evolved from earlier concepts such as Peter Todd’s proposal on single-use seals in 2014 and was more formally defined thanks to Giacomo Zucco and Riccardo Casatta in 2016. Despite Tether’s initial interest in the protocol, its implementation faced delays while development continued under previous teams.
Additional Developments from Tether
In addition to the forthcoming USDT initiative, Tether has introduced several Bitcoin-centric products this year, including a Bitcoin-focused Mining Development Kit made available in April and their freshly released self-custodial tether.wallet application, which supports transactions in Bitcoin, Lightning, and USDT.
