The Utexo product suite packages execution, settlement, liquidity access, and asset exchange into a unified stack for stablecoin payments on Bitcoin. Each component addresses a distinct layer of the payment infrastructure and can be used independently or together through a single API integration. By grouping these components under a common execution model, Utexo reduces the need for custom orchestration between settlement, exchange, and routing layers, allowing operators to deliver consistent and predictable payment experiences without managing the underlying Bitcoin, Lightning, or RGB infrastructure directly.Documentation Index

SDK
REST API and client library for native USDT transfers and RGB asset operations on Bitcoin.
Cloud
Managed infrastructure for running RGB-enabled Lightning nodes without self-hosting.
Bridge
Atomic stablecoin transfers from EVM networks and Tron to native Bitcoin RGB USDT.
Swap
Non-custodial BTC ↔ USDT swaps with instant finality and LP functionality.
SDK
The Utexo SDK and REST API allows applications to support native USDT transfers and other RGB assets on Bitcoin without operating Bitcoin nodes, managing Lightning liquidity, or maintaining RGB state infrastructure. The SDK provides programmatic access to:- RGB asset operations — privacy-preserving asset issuance, transfers, and state transitions
- Lightning execution — routing, payment lifecycle, and failure recovery
- Balance and audit — balance tracking, transaction status, and transfer history
See the SDK reference for installation, method reference, and integration examples.
Cloud
Utexo Cloud Modules provide managed execution infrastructure for operators who need RGB-enabled Lightning node capabilities without running self-hosted infrastructure. It acts as a control plane for running and managing RGB-enabled Lightning nodes. Capabilities include:- Node lifecycle management — provisioning, upgrades, and teardown
- Health and status monitoring — real-time node diagnostics
- Managed backup and recovery — encrypted state backups with point-in-time restore
- VSS integration — Verifiable Secret Sharing for non-custodial cloud key management
See the Cloud documentation for setup and configuration.
Bridge
The Utexo Bridge acts as the liquidity gateway for native USDT on Bitcoin. It enables fully atomic stablecoin transfers from external EVM-based networks and Tron to the RGB protocol on Bitcoin. USDT bridged to Bitcoin is represented as native RGB USDT — the same asset used across all Utexo payment flows. No wrapped or synthetic representations are introduced. Key properties:- Atomic cross-chain transfers — no custodian or intermediary holds funds during the bridge process
- EVM and Tron support — compatible with the networks where most USDT supply exists today
- Native RGB output — bridged assets are immediately usable in Utexo payment and swap flows
See the Bridge documentation for supported networks and integration steps.
Swap
The Utexo Swap DEX provides non-custodial BTC ↔ USDT exchange on Bitcoin with instant finality. It enables operators and users to rebalance between BTC and stablecoin positions without leaving the RGB/Lightning stack. Key properties:- Native BTC ↔ USDT swaps — settled directly on the RGB protocol with Lightning execution
- Privacy-preserving — swap activity uses the same client-side validation model as standard RGB transfers
- LP functionality — liquidity providers can supply RGB-native assets and earn fees
- Instant finality — trades settle without waiting for on-chain confirmations
See the Swap documentation for trading and liquidity provider guides.
