Utexo is a Bitcoin-native execution and settlement layer that enables native USDT payments on Bitcoin, built on top of the Lightning Network and RGB.
Utexo abstracts the complexity of Lightning routing, liquidity management, and RGB state handling into a single SDK and API, allowing applications to support USDT on Bitcoin without operating Lightning nodes, managing channels, or maintaining RGB infrastructure.
At the protocol level, Utexo combines:
- Bitcoin for double-spending prevention, security, and finality
- Lightning Network for instant, low-cost transaction execution
- RGB for client-side validated asset issuance, transfers, and programmability
This architecture allows USDT to operate natively on Bitcoin without wrapped assets, account-based smart contracts, or external Layer-1 dependencies, while keeping transaction data off public ledgers and preserving Bitcoin’s security model.
Product Suite
- Utexo SDK & APIs
A production-ready SDK and REST API providing programmatic access to:
• Lightning execution, routing, and failure recovery
• RGB asset issuance, transfers, and state transitions
• Balance tracking, transaction status, and audit logs
The SDK enables non-custodial, client-side validated flows, without requiring developers to operate Lightning nodes or manage RGB infrastructure directly.
- Bitcoin-Native USDT Bridge
A atomic bridge that converts stablecoins from other networks into RGB-based USDT on Bitcoin, without counterparty risk.
Designed for direct integration into wallets, exchanges, and settlement systems.
- Bitcoin-Native BTC/USDT DEX
A non-custodial BTC/USDT decentralized exchange built directly on Bitcoin using RGB and Lightning.
The Utexo DEX enables native BTC ↔️ USDT swaps with execution and settlement anchored to Bitcoin, without relying on account-based execution layers, wrapped assets, or external smart contracts.
Trades are cleared off-chain and settled with instant finality, enabling low-latency swaps with predictable fees.
- Cloud Modules
Infrastructure modules that allow developers to build:
• Yield mechanisms on BTC and USDT balances
• Liquidity provisioning workflows
Settlement and routing incentive systems
These modules are optional and composable, depending on application requirements.
Use Cases
Using Utexo, developers can implement:
- Instant BTC and USDT transfers on Bitcoin
- Native BTC ↔️ USDT swaps without centralized exchanges
- Off-chain clearing and settlement flows anchored to Bitcoin
- Payment, treasury, and settlement infrastructure for wallets, exchanges, and PSPs
Utexo integrates cleanly into existing systems through deterministic APIs, enabling programmatic control over execution, settlement, and asset state without reliance on centralized remote services.
Integration Model
Developers interact with Utexo via:
• A production-ready SDK and REST API
• Programmatic access to Lightning execution and RGB asset operations
• Fully non-custodial flows with client-side validation
All validation and state transitions occur client-side, maintaining a self-custodial, trust-minimized architecture aligned with Bitcoin’s ethos.
