Guides and reference material for building on Kaspa.Guides are step-by-step how-tos. Reference is lookup material - verified against rusty-kaspa and the KIPs repo where possible.
Guides
- Run a Node — install, run, and verify a rusty-kaspa full node.
- Use Testnet — develop against testnet-10: node flags, SDK network ids, test KAS.
- Connect with the WASM SDK — connect from JavaScript/TypeScript with RpcClient and Resolver.
- Connect with the Python SDK — the same connection flow from Python.
- Build a Transaction — build, sign, and submit a transaction with the WASM SDK.
Reference
