MV Capital - USDT Returns to Bitcoin via RGB Protocol for Native Settlements

Tether prepares to issue USDT natively on Bitcoin through the RGB protocol in partnership with UTEXO, enabling use of Bitcoin addresses and Lightning Network for transfers. The move returns the stablecoin to its original blockchain after years on other networks

Background on USDT and Bitcoin

Tether first issued USDT on Bitcoin in 2014 using the Omni-Mastercoin Layer. Over time, activity shifted to other chains like Tron and Ethereum due to lower fees and faster processing. Tron now handles a large share of USDT transfers, especially in certain markets.

The upcoming launch marks a return to Bitcoin. It uses RGB protocol version v0.11.1, deployed through software company UTEXO in direct partnership with Tether. UTEXO acts as the issuer and distributor for this Bitcoin-native version of USDT.

Lightning Network for instant off-chain payments
Client-side validation to keep most data off the main chain
Bitcoin's UTXO model for transaction structure

Technical Details of RGB on Bitcoin

RGB builds on Bitcoin's UTXO model combined with client-side validation and Lightning Network capabilities. This setup allows users to send and receive USDT using standard Bitcoin addresses while settling transactions quickly through Lightning channels.

The approach provides privacy advantages. Bitcoin generates fresh addresses per transaction, unlike account-based systems that often reuse addresses. Lightning routing further limits on-chain visibility. No separate token is needed for fees, removing a common point of friction seen on networks like Tron where an additional asset covers transaction costs.

UTEXO has developed supporting tools including APIs, a software development kit, user interface components, and a live mint bridge for cross-chain movements. These elements aim to support integration by wallets and exchanges.

“We built Utexo so that USDT could move on Bitcoin the way money is supposed to move: instantly, privately, with no surprises on costs.”Viktor Ihnatiuk, UTEXO co-founder

Development History and Timeline

RGB traces back to ideas from Peter Todd in 2014 on single-use seals. It was formalized in 2016 by Giacomo Zucco and Riccardo Casatta. Later development involved Federico Tenga from Bitfinex R&D. The protocol reached mainnet readiness with version v0.11.1.

Delays in earlier stages allowed other networks to capture significant USDT volume. UTEXO emerged from a joint effort involving Boosty Venture Studio, Fulgur Ventures, and Tether Investments to complete the commercial implementation.

The rollout is expected within weeks, possibly in July 2026. Tether Wallet and various exchanges plan to add support. Users will handle USDT alongside Bitcoin in compatible setups.

Statements from the project“For the first time in eight years or nine years, USDT is coming back home.”

Comparison with Current USDT Networks

Current dominant networks for USDT offer low costs and speed but introduce elements like separate fee tokens and account-based address reuse. Bitcoin with RGB targets these areas by keeping everything within the Bitcoin ecosystem's security model and Lightning infrastructure.

Direct integration with Tether reduces reliance on additional intermediaries for minting and transfers. Potential for near-instant swaps between Bitcoin and USDT on the same rails is noted as a practical improvement over multi-step processes involving external services.

Address Model	UTXO fresh addresses	Often reusable accounts
Fees	Bitcoin native, no extra token	Requires separate gas token
Settlement	Lightning for speed	On-chain primary

Broader Context

This development fits with Tether's recent Bitcoin-related activities, including tools for miners and self-custodial wallet support. The stablecoin market continues to evolve with competition among issuers and underlying networks.

Success depends on adoption by wallets, exchanges, and users. The launch provides another option for USDT transfers anchored to Bitcoin's established infrastructure.

“Finally, after eight years of development—if not more—we are the company that is launching USDT over Bitcoin with strong support from Tether.”Viktor Ihnatiuk, UTEXO co-founder
