Product Suite

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.

​

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

The SDK enables non-custodial, client-side validated flows without requiring developers to operate Lightning nodes or manage RGB infrastructure directly. All API calls execute with predefined costs and latency characteristics.

​

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

​

Mint

The Utexo Mint acts as the liquidity gateway for native USDT on Bitcoin. It enables cross-chain stablecoin transfers from external EVM-based and Non-EVM networks to the RGB protocol on Bitcoin. USDT minted 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:

• Cross-chain transfers — no custodian or intermediary holds funds during the mint process
• EVM and Non-EVM support — compatible with the networks where most USDT supply exists today
• Native RGB output — minted assets are immediately usable in Utexo payment and swap flows

​

Swap

Utexo Swap is an intent-based liquidity layer for cross-chain swaps across Bitcoin, Ethereum, Tron, and Solana, exposed through a single REST API for wallets, exchanges, and other integration partners. Key properties:

• Competitive pricing — resolvers compete through request-for-quote (RFQ) to price and fulfill each swap
• Non-custodial — each swap settles through a dedicated escrow on the source chain; it completes in full or refunds
• One integration — quotes, intents, chain-specific approvals, and status tracking through one API
• USDT on Bitcoin — see RGB USDT in Utexo Swap for what platforms and resolvers need
