Tether is preparing to issue USDT natively on Bitcoin through the RGB protocol version v0.11.1, marking the stablecoin's return to the chain where it first launched in 2014 via Omni-Mastercoin. UTEXO, a software lab funded by Tether Investments and other backers, is leading the commercial rollout as issuer and distributor.
The move ends a gap of nearly a decade. RGB entered active development around 2016 but missed deployment windows that might have shaped the stablecoin landscape differently. In the interim, USDT migrated to Tron, Ethereum, and other chains, with Tron capturing dominant USDT volume in developing markets. "For the first time in eight or nine years, USDT is coming back home," Viktor Ihnatiuk, UTEXO co-founder, told Bitcoin Magazine.
How RGB and Lightning change the user experience
RGB combines client-side validation with the Bitcoin UTXO model and the Lightning network for offchain settlement. Users can hold USDT on native Bitcoin addresses and route it over Lightning with compatible wallets, bypassing middlemen and the fees they impose.
The privacy model differs sharply from Ethereum and Tron, which use account-based addresses and encourage reuse. Bitcoin's UTXO model generates a fresh address per transaction. RGB's offchain settlement over Lightning further reduces blockchain footprints. Tether's direct integration means fewer intermediaries collecting data or charging extra layers of fees.
Ihnatiuk contrasted the experience with current swap mechanics: moving USDT across chains typically costs three percent when combining wallet fees, swap commissions, and slippage. Bitcoin and Lightning remove that friction. Users can swap USDT to bitcoin instantly without slippage and near spot-market pricing, he said, with fees baked into a single transaction.
Networks like Tron require users to pay fees in TRX, forcing an extra asset purchase when the goal is simply to move stablecoin. Bitcoin's status as the oldest and most established blockchain also matters to Tether's calculus. Regulatory scrutiny of newer chains and the risk of contentious forks or critical bugs are absent from Bitcoin's track record.
Technical roots and the UTEXO bridge
RGB traces its lineage to Peter Todd's single-use seals (2014) and was formalized in 2016 by Giacomo Zucco and Riccardo Casatta. The acronym originally meant "Riccardo Giacomo Bitcoin" and was later rebranded "Really Good Bitcoin." Bitfinex R&D Strategist Federico Tenga developed the RGB protocol layer.
UTEXO emerged from a joint venture between Viktor's Boosty Venture Studio, Fulgur Ventures, and Tether Investments. The company positioned itself as building the final-mile infrastructure for RGB adoption: SDKs, APIs, UI design, and middleware protocols.
A live mint bridge at mint.utexo.com lets users move USDT across blockchains with deterministic fees and no intermediary cut, thanks to direct integration with Tether as the primary mint. This removes the margin-taking layer that typically sits between user and issuer.
Launch timeline and next steps
UTEXO expects to launch USDT on Bitcoin within weeks, possibly July. Wallets including Tether Wallet and exchanges worldwide are announcing support. The rollout comes as Bitcoin holds the top market cap position at roughly $63,800 and Tether USDT maintains its rank as the third-largest asset by market capitalization at approximately $0.999.
