Solv and Utexo Launch BTC–USDT Atomic Swap Yield

Solv Protocol and Utexo announced an integration on April 15 that creates a bitcoin-native USDT yield infrastructure using the RGB protocol and the Lightning Network. The system enables direct, atomic swaps between bitcoin (BTC) and USDT that settle on Bitcoin’s UTXO model without wrapped tokens or cross-chain bridges.

Solv, an onchain Bitcoin asset management platform reporting more than $2 billion in reserves, partnered with Utexo, a non-custodial settlement layer built on RGB and Lightning. The companies said atomic swaps execute directly between counterparties, preserving self-custody and settlement finality while keeping transaction details confidential through RGB’s client-side validation.

Technically, the integration uses RGB to issue and validate tokenized assets off-chain while anchoring state to Bitcoin UTXOs. Lightning is used for low-fee, near-instant settlements; the partners noted Lightning payments can finalize in roughly 50 milliseconds. The offering includes enterprise-facing APIs intended to support funds, exchanges and decentralized finance protocols.

Solv participated as a strategic angel investor in Utexo’s $7.5 million seed round, which the companies reported was led by Tether alongside other backers. The announcement referenced Tether’s August 2025 plan to issue USDT natively on RGB-compatible Lightning rails and positioned the integration as a technical match for that roadmap.

The companies described the integration as targeting workflows that require regulated access, collateral management and high-throughput settlement with predictable costs. The stack is designed to support private execution and to avoid intermediaries and wrapped tokens that introduce custody and counterparty risk.

Ryan Chow, co-founder and CEO of Solv Protocol, described the offering as an effort to build yield directly on native Bitcoin rails while prioritizing security, privacy and settlement integrity at institutional scale. Viktor Ihnatiuk, co-founder and CEO of Utexo, said the RGB–Lightning architecture enables scalable, enterprise-grade yield and aligns with plans for native USDT on Lightning.

The companies said they expect adoption to increase through 2026 as Bitcoin-native stablecoins and Lightning-based settlements expand. They also said the integration is intended to support new onchain financial flows and regulated uses built on Bitcoin’s rails.
