Utexo, a startup backed by Tether, is launching a native version of USDT on Bitcoin this month, bringing the world’s largest stablecoin back to the network it left more than a decade ago. The rollout uses RGB protocol v0.11.1, a Bitcoin asset standard developed by Utexo’s team, and is the second route Tether has taken back to Bitcoin this year after a March integration through Lightning Labs’ Taproot Assets.
Utexo co-founder Victor Ihnatiuk called the launch a milestone for Bitcoin:
“For the first time in eight 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,”
he told Bitcoin Magazine. Tether CEO Paolo Ardoino described the return on X as “It’s coming home.”
Tether’s USDT, valued around $190 billion, first launched on Bitcoin’s Omni layer in 2014 but moved to Tron and Ethereum for lower fees and broader infrastructure. About 85 percent of the supply now sits on those two networks. This shift left Bitcoin with almost no stablecoin activity, a role driven by fees and user base rather than technical barriers.
How RGB differs from Taproot Assets
RGB is a Bitcoin asset protocol developed by Utexo and refined over several releases. Rather than writing tokens into public Bitcoin outputs like Taproot Assets does, RGB keeps transaction data off-chain, so the Bitcoin ledger records only a small commitment to ownership without exposing balances or counterparties. This design allows private transfers and direct swaps between native bitcoin and USDT inside the same wallet, with loans backed by native bitcoin supported at launch.
Utexo plans to expand USDT to Bitcoin’s Lightning Network after the main rollout. The company said it will blacklist UTXOs tied to sanctioned or illicit activity rather than freezing whole addresses, a design that separates enforcement from address-level control. Coindesk reported the plan on September 29.
What this means for Bitcoin’s role
Whether Bitcoin becomes a stablecoin settlement layer again depends on exchanges, wallets and payment operators, not on the protocol itself. Utexo has said early integration work is under way with several exchanges and wallet providers, but no major platform has announced support publicly. In practice, most stablecoin transfers on Tron and Ethereum are used for exchange deposits and remittances, a market that has resisted switching to new rails regardless of fees.
The Taproot Assets rollout in March gave Bitcoin a first stablecoin route through Lightning-compatible infrastructure, but the token has seen little adoption on Bitcoin so far. RGB is positioned differently: it supports confidential transfers, native bitcoin swaps and bitcoin-backed loans all at once, giving operators a transaction mix closer to what users expect on Ethereum-based systems. Utexo raised a $7.5 million seed round co-led by Tether and plans to expand further to exchanges and payment processors in Asia.
February comparisons and what is next
The launch comes as Tether continues to diversify its holdings. The company’s reserves include billions in US treasury securities, gold and bitcoin, and the firm said in March that realized profits for the previous year were around $13 billion. How much that matters for a Bitcoin-native USDT is unclear: the redemption guarantee and reserve backing are the same regardless of which chain holds the token, so the appeal is again a question of utility, price, and whether the Bitcoin network itself remains the cheapest place to settle stablecoin transfers.
Utexo’s roadmap puts Lightning support and broader exchange listings in the coming months, with payment processors for merchants in emerging markets a stated priority. A rollout on Bitcoin mainnet, if it holds to the October timeline, would be the largest single stablecoin migration to Bitcoin since USDT left the Omni layer.
Adoption will rest with exchanges and merchants
Reaching Bitcoin users through stablecoins is a long-standing project that has failed before. Liquid Network, a Bitcoin sidechain launched in 2018, supported USDT for years before winding down as volumes shifted elsewhere. Lightning Labs’ Taproot Assets rollout in March, backed by Tether directly, found little exchange uptake in its first months. Utexo is the third attempt in as many years, and follows a different architecture that the company argues can succeed where those two efforts could not.
Behind the protocol choice, the economics are unchanged. Tron processes USDT transfers for fractions of a cent, with widely available wallet support and exchange integration. Bitcoin’s fees, while lower than during bull markets, still sit above Tron’s, and wallets that can hold both bitcoin and an RGB-based USDT in the same interface are not yet widely available. Utexo says the first compatible wallets are being prepared but has not named which ones.
Whether merchants adopt the token on Bitcoin will likely match wider stablecoin payment trends. Recent estimates by the ECB and others suggest fewer than one in a hundred European online merchants accept any crypto asset today, a figure that has barely moved for two years.
What the ledger records
The RGB design means most transaction details stay off the public chain. Utexo says this keeps balances and counterparties private, a feature that has drawn interest from users who want to move stablecoins without exposing amounts and recipients for anyone to see. Regulators have pushed back on privacy tools in the past, and the company has said its blacklist process is meant to address sanctions and illicit use while keeping lawful transfers private. How US authorities will treat that combination has not been tested.
For Bitcoin holders, the practical change is small at launch. The token runs on a protocol many wallets do not yet support, and anyone holding USDT on an exchange today can continue to withdraw on Tron or Ethereum as before. Utexo’s bet is that wallet support arrives first, then merchants, then exchanges, in roughly that order. Its own funding, co-led by Tether, gives the project a runway to push those integrations for months without needing to charge fees early.
