This section documents public interfaces exposed by the Transfer Settlement Network (TSN), TrustLink Labs’ implementation of a Decentralized Settlement Protocol (DESP). DeFi decentralizes financial services; DESP decentralizes settlement infrastructure. The pages here describe what an application, operator, or integrator can call and what the source currently guarantees.

​
Scope

The inventory is grouped by the public surface that owns the contract:
  • RPC Methods: FastAPI Node endpoints and the Solana JSON-RPC gateway’s HTTP control endpoints.
  • SDK: @trustlink/tsn-sdk application helpers and @trustlink/tsn-cranker-sdk operator helpers.
  • CLI: setup commands exposed by the Cranker SDK package.
  • On-chain Programs: public Solana instruction entrypoints that settle or register protocol state.
No webhook group is listed because the scanned source does not expose a consumer webhook dispatcher. Receiver and worker communication is authenticated HTTP work leasing, not a public webhook contract.

​
Base URLs

The SDK chooses local endpoints before live endpoints when both are supplied to getTsnNetworkStatus. Applications should use the gateway URL rather than embedding an upstream Solana provider URL.

​
Versioning and evidence

The reference is generated from the source paths linked at the bottom of each page. It does not promote an interface merely because a route is present in configuration. A destination route must pass the Node’s registered-route and live-liquidity checks before it is returned as ready. When a type or account layout cannot be established from the inspected source, the page says TODO: confirm from ... rather than inventing a field.
