# SDK **Overview** Our SDK 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 provide programmatic access to: * RGB privacy-preserving asset issuance, transfers, and state transitions * Lightning execution, routing and failure recovery * 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. All API calls execute with predefined costs and latency characteristics, and can be integrated into existing backend systems or user-facing applications. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
