Utexo, a Dubai-based blockchain startup, is preparing to reintroduce Tether’s USDT stablecoin to the Bitcoin network after a three-year absence. The integration utilizes RGB, a protocol that keeps asset transaction data off-chain, with a public launch scheduled for November 28 and Lightning Network support planned for Q1 2027. This move aims to provide private and fast payments via Bitcoin’s infrastructure, addressing previous declines in usage that led Tether to halt issuance on the Omni protocol in August 2023.
The initiative stems from Tether’s earlier announcement in August 2025 regarding plans to launch USDT on RGB, followed by Tether leading Utexo’s $7.5 million seed round in March. Utexo will deploy the Bitcoin version of the stablecoin using Tether’s USDT0 protocol. Viktor Ihnatiuk, co-founder and CEO of Utexo, emphasizes that speed and privacy are the primary drivers for this return, leveraging Bitcoin as a settlement layer while RGB ensures transaction details remain confidential. The company opened early access to its USDT Mint product on October 22 for verified professional operators to test minting and redemption on Bitcoin’s Signet test network.
To transfer existing USDT to Bitcoin through Utexo Mint, users must lock USDT0 on Arbitrum before an equivalent amount of USDT is minted on Bitcoin. Redemption involves burning the RGB asset to release funds on the source network. This architecture introduces cross-chain security dependencies, as the system relies on the integrity of the bridge between Arbitrum and Bitcoin rather than Bitcoin alone. While audited by Oxorio, the full report remains unavailable publicly. Utexo has partnered with UniSat and is working with numerous over-the-counter partners to facilitate adoption.
The reintroduction of USDT to Bitcoin via RGB represents a strategic pivot toward leveraging Bitcoin’s security for stablecoin settlement while bypassing its limitations in smart contract complexity. By focusing on privacy and speed through off-chain data handling, Utexo attempts to carve out a niche distinct from Ethereum’s DeFi dominance and Tron’s retail volume. However, the reliance on a bridge mechanism involving Arbitrum introduces significant operational risk, as the security of Bitcoin-native assets becomes contingent on external chain integrity and bridge solvency, a vulnerability historically exploited in cross-chain attacks.
Market competition remains fierce given the $300 billion stablecoin supply already entrenched on other networks. Success depends not just on technical execution but on convincing institutional operators that the trade-off between Bitcoin’s robust settlement finality and the added complexity of RGB validation is worthwhile. If Utexo can demonstrate reliable liquidity and seamless integration for exchanges and miners, it may capture a segment of the market prioritizing confidentiality and base-layer security over composability. Conversely, failure to address bridge risks or achieve critical mass could render the project a marginal experiment rather than a viable alternative to incumbent chains.
