# BCTS — Blockchain Commons TypeScript

> TypeScript implementations of Blockchain Commons specifications including dCBOR, Gordian Envelopes, Uniform Resources, SSKR, and other cryptographic standards.

This file follows the [llms.txt](https://llmstxt.org) convention. Each link below points at a per-package `llms-full.txt`: a concatenated Markdown reference for that package's full TypeScript API, suitable for direct ingestion by Claude, Cursor, ChatGPT, Windsurf, and similar tools.
