Tether challenges Tron’s stablecoin dominance with Bitcoin-native USDT
Tether is preparing to reintroduce USDT natively on Bitcoin through the RGB protocol, a move that could reshape stablecoin payments if exchanges, wallets, and payment providers embrace the new infrastructure.
Tether is preparing to issue USDT natively on Bitcoin for the first time in over a decade, using the RGB protocol with Lightning Network support. The move, expected as early as July 2026, aims to challenge Tron and Ethereum’s dominance of USDT circulation, the two networks currently hold roughly 85% of all USDT in circulation, according to Tether’s transparency data.
The rollout is designed to deliver faster, lower-cost and more private USDT transactions while leveraging Bitcoin’s unmatched security. If widely adopted, the initiative could reduce reliance on Ethereum and Tron, the two networks that currently dominate USDT circulation.
According to Tether’s transparency data, roughly 85% of all USDT currently resides on the Tron and Ethereum blockchains, underscoring how those ecosystems have become the primary settlement networks for the stablecoin. By re-establishing Bitcoin as a viable settlement layer, Tether hopes to offer traders, exchanges and payment providers a compelling alternative.
Bitcoin welcomes USDT home through RGB
The upcoming deployment will see USDT issued through RGB v0.11.1, a Bitcoin-native asset protocol developed by software company UTEXO, which is partnering with Tether as the issuer and distributor.
USDT originally launched on Bitcoin in 2014 through the Omni Layer before migrating toward Ethereum and later Tron as lower transaction fees, better infrastructure and broader developer support accelerated adoption on those networks.
Now, the Tether Bitcoin return represents an attempt to reclaim Bitcoin’s role in stablecoin settlements using modern technology that did not exist during the Omni era.
Speaking to Bitcoin Magazine, UTEXO co-founder Victor Ihnatiuk described the launch as a defining moment for Bitcoin’s evolution.
“For the first time in eight years or nine years, USDT is coming back home. We have no chance to fail. If we fail, no one will think about Bitcoin as a settlement layer anymore,” Ihnatiuk said.
Unlike earlier implementations, RGB processes much of its transaction validation off-chain while committing only minimal cryptographic proofs to Bitcoin. This significantly reduces blockchain congestion while preserving Bitcoin’s security guarantees.
Users will also be able to store USDT directly in Bitcoin wallets and transfer funds using Lightning-compatible applications, opening new possibilities for cross-border payments and merchant settlements.
RGB and Lightning aim to make Bitcoin a stablecoin powerhouse
The latest Tether Bitcoin return initiative follows another milestone reached earlier this year.
In March 2026, Tether completed its USDT integration on Bitcoin using Lightning Labs’ Taproot Assets protocol. That implementation relied on Bitcoin’s Taproot upgrade, which introduced greater privacy, scripting flexibility and efficiency.
RGB, however, takes a different architectural approach.
According to the RGB Protocol Association, RGB validates most transaction data outside the blockchain while anchoring only cryptographic commitments on Bitcoin itself. The design allows Bitcoin to support tokenized assets without overwhelming the network with additional data.
By contrast, Taproot Assets records asset commitments directly inside Taproot outputs while remaining tightly integrated with Lightning.
Although both frameworks pursue similar objectives—bringing stablecoins and tokenized assets onto Bitcoin—they compete to become the preferred infrastructure layer for future Bitcoin-based financial applications.
Ihnatiuk believes RGB simplifies digital asset transfers by eliminating the need to bridge value across multiple blockchains.
“With USDT and Bitcoin over Lightning, for the first time you have two main assets on one chain; you can swap instantly without any slippage,” he said.
Importantly, RGB has already matured beyond the experimental phase. Version 0.11.1 officially launched on Bitcoin’s mainnet in July 2025, providing the production-ready foundation for Tether’s latest deployment.
The Tether Bitcoin return is supported by growing institutional investment around the RGB ecosystem.
UTEXO itself emerged through collaboration between Boosty Venture Studio, Fulgur Ventures and Tether Investments. The company recently secured $7.5 million in fresh funding led by Tether alongside BigBrain VC and Portal Ventures, highlighting increasing confidence in Bitcoin-native asset infrastructure.
Momentum has continued across the broader ecosystem.
Earlier this year, Solv Protocol partnered with UTEXO to introduce Bitcoin-native yield strategies powered by direct Bitcoin-to-USDT transactions. The companies also integrated with the x402 payment protocol, enabling machine-to-machine USDT payments with settlement speeds reportedly as low as 50 milliseconds.
The developments suggest that Bitcoin’s role is gradually expanding beyond being simply a store of value toward supporting payments, decentralized finance and tokenized assets.
Adoption remains the biggest hurdle to challenging Tron
Despite the technological progress, analysts caution that the success of the Tether Bitcoin return will ultimately depend less on protocol design than on ecosystem adoption.
Researchers at Galaxy Research previously noted that bringing USDT back to Bitcoin demonstrates the blockchain’s growing versatility beyond its “digital gold” narrative. However, they also warned that displacing Tron as the dominant stablecoin settlement network will be difficult given its deep liquidity, widespread exchange support and established payment infrastructure.
That means wallets, exchanges and payment processors will play a decisive role in determining whether Bitcoin-native USDT gains meaningful traction.
Meanwhile, Lightning Network usage continues to accelerate. According to River Financial, Lightning processed an estimated $1.17 billion in payment volume across more than 5.22 million transactions during November 2025, marking the network’s first month above the $1 billion threshold.
Industry reports also highlighted a $1 million Lightning transfer completed on Kraken in just 0.43 seconds during January 2026, demonstrating the network’s ability to support high-value transactions with near-instant settlement.
The Tether Bitcoin return therefore arrives at a time when Bitcoin’s payment infrastructure is significantly more mature than it was during USDT’s original launch in 2014.
Whether Bitcoin can reclaim a meaningful share of stablecoin settlement volume now depends on how quickly exchanges list the RGB-based USDT, wallets integrate support and merchants begin accepting Lightning-powered payments.
While Tether will continue issuing USDT centrally regardless of the blockchain, the settlement layer underneath could soon look very different. If adoption follows technological progress, Bitcoin may once again become a major home for the world’s largest stablecoin—and for the first time in nearly a decade, challenge Tron and Ethereum in the race for stablecoin dominance.
