Tether is preparing to launch native USDT on Bitcoin through RGB protocol version v0.11.1, a move that would bring the stablecoin back to the blockchain where it first appeared in 2014 through the Omni-Mastercoin Layer. The commercial rollout is being led by UTEXO, which says it is working directly with Tether and has positioned itself as the issuer and distributor for this Bitcoin-native version of USDT.
In comments cited by Bitcoin Magazine, UTEXO co-founder Viktor Ihnatiuk said the launch comes after at least eight years of development efforts around RGB. He described UTEXO as the company finally bringing USDT back to Bitcoin with strong support from Tether. Based on the current timeline, USDT over RGB is expected to go live within weeks, potentially in July, while wallets including Tether Wallet and exchanges in multiple regions are said to be preparing integrations.
RGB combines Bitcoin’s UTXO model with Lightning settlement
Technically, the plan centers on RGB’s client-side validation architecture, paired with the Lightning Network for instant and more private settlement, while security remains anchored to Bitcoin’s UTXO model. According to the rollout plan, users should be able to manage USDT on native Bitcoin addresses and send or receive it over Lightning using compatible wallets.
UTEXO argues that this structure offers a different user experience from the account-based chains that currently dominate USDT activity. On networks such as Tron, Ethereum, and Solana, address reuse is common at the interface level. By contrast, Bitcoin’s UTXO model naturally supports fresh addresses across transactions, which the company presents as a meaningful privacy advantage. RGB’s Lightning integration is meant to go further by moving transfers onto an off-chain payments layer, leaving fewer traces on the public blockchain.
Viktor said UTEXO was built so that USDT could move on Bitcoin “the way money is supposed to move,” emphasizing instant settlement, privacy, and predictable costs. He added that partners only need to integrate UTEXO’s API once in order to route USDT across the network while keeping control over their own fee structure. UTEXO also claims that deeper coordination with Tether reduces the number of intermediaries involved, lowering both extra charges and data collection points.
UTEXO is positioning the product against Tron’s USDT dominance
UTEXO emerged from a joint effort involving Viktor’s Boosty Venture Studio, Fulgur Ventures, and Tether Investments. Its stated mission is to push RGB to mainnet after years of delays under prior teams. The article notes that RGB had been under active development since at least 2016 but was not ready in time for the 2017 bull market. That delay helped Tron establish itself as the dominant network for USDT volume and usage across much of the developing world, a position it still largely holds.
To challenge that status quo, UTEXO says it is building the “last mile” infrastructure required for large-scale Bitcoin-native USDT deployment. That includes a software development kit, APIs, middle-layer protocols, interface work, and a mint bridge already live at mint.utexo.com. The bridge is described as enabling USDT transfers across major blockchains with deterministic low fees and no middlemen because of its direct integration with Tether as the primary mint. The article also says the RGB protocol layer was developed by Bitfinex R&D Strategist Federico Tenga.
Viktor contrasted the new setup with existing conversion flows for users who want to move between USDT and Bitcoin. He said that in the current market, users often pay around 1% in wallet fees, another 1% or more to swap providers, plus roughly 1% in slippage, bringing total costs near 3%, while also waiting a long time for execution. With USDT and Bitcoin both operating through Lightning and Bitcoin-based rails, he argued, users could for the first time handle two major assets on one chain and swap between them almost instantly with minimal slippage. He added that pricing is “almost the same as spot markets in Binance.”
Privacy, cost efficiency, and Bitcoin’s security narrative
The article frames the initiative as a direct response to the frictions embedded in today’s USDT transfer networks. On chains such as Tron, users typically need a separate address format and must hold another token, such as TRX, to pay fees. In practice, that means buying an additional asset simply to move stablecoins. With much of crypto’s monetary activity concentrated in Bitcoin and Tether, UTEXO argues that this extra step feels increasingly unnecessary and inefficient.
The company also stresses the security profile of using Bitcoin as the settlement rail for USDT. While USDT itself remains fundamentally centralized at the issuer level because Tether controls issuance and redemption, the blockchain underneath still matters. Novel chains may introduce additional risks through contentious forks, immature infrastructure, or major bugs. Bitcoin, by contrast, is presented as the oldest and most conservative blockchain, offering a level of operational assurance that competing networks cannot easily match.
From a historical perspective, RGB traces its roots to Peter Todd’s single-use seals concept in 2014 and was formalized in 2016 by Giacomo Zucco and Riccardo Casatta. The RGB name originally stood for “Riccardo Giacomo Bitcoin” before later being reinterpreted as “Really Good Bitcoin.” According to the report, Tether explored the protocol early on but progress stalled because of delays under the previous development team. Had RGB launched on time around 2019, the stablecoin market and the broader DeFi stack may have evolved more around Bitcoin’s UTXO model instead of Ethereum’s account-based architecture.
Launch window is approaching, with wallets and exchanges preparing support
For UTEXO, bringing USDT back to Bitcoin is more than a product release. Viktor described it as the stablecoin “coming back home” for the first time in eight or nine years. He added that if the effort fails, the market may become even less willing to think of Bitcoin as a settlement layer. That helps explain why UTEXO is trying to coordinate the launch across wallets, exchanges, bridge infrastructure, and developer tooling at the same time.
Based on the details released so far, the Tether-UTEXO-RGB combination is attempting to reshape how USDT is distributed and moved on-chain. On one side, it offers a model built on Bitcoin’s UTXO structure and the Lightning Network, promising lower friction, stronger privacy, and more native Bitcoin-style asset handling. On the other, it directly targets Tron’s entrenched lead in stablecoin transfers. Whether that challenge succeeds will likely depend on wallet compatibility, exchange participation, and real user migration, but the reported launch window suggests the project is now in its final approach to market.
