42,000 lines of production Rust powering payment channels, P2P authentication, AI payment agents, and merchant infrastructure — all native to Kaspa L1. No theory. Real operations.
// Native Kaspa P2SH Funding Transaction

// Sign directly with secp256k1 keypair

Ok(signed_tx.tx)No wrapped tokens. No sidechains. Pure layer-1 Kaspa transactions with P2SH channel optimizations.
Sub-second confirmation times powered by Kaspa's BlockDAG. No more waiting for block confirmations.
Microtransactions are finally viable. Accept payments for fractions of a cent without eating your margins.
Powered by native P2SH payment channels. You hold the keys; the Guardian node just enforces the rules.
Built to handle Kaspa's massive 10+ BPS throughput. Infrastructure that scales as fast as your user base.
These examples are fully open source. Learn the kdapp architecture, experiment with real blockchain transactions, and build your foundation.
True P2P authentication on Kaspa L1. Real secp256k1 signatures, blockchain-verified sessions, WebSocket updates. The unphishable login system.
View on GitHub →Decentralized commenting with economic bonds. Participants stake KAS to post, community moderation through episode contracts. Censorship-resistant by design.
View on GitHub →Decentralized comment system with Kaspa authentication. Users bond KAS to post, moderators manage content. Full on-chain governance and dispute resolution.
View on GitHub →Production-grade payment infrastructure built on Kaspa L1. P2SH channels, merchant APIs, dispute resolution, AI agent payments — everything you need to accept KAS at scale.
Complete payment system with invoices, subscriptions, webhooks, P2SH payment channels, and HTTP API. Accept KAS like Stripe accepts USD.
Lightweight watchtower for dispute resolution. Watches the DAG for checkpoint anchors, co-signs refunds, and enforces payment guarantees.
Beautiful terminal UI that orchestrates merchant, watcher, and guardian. One-command autopilot for instant deployment. See everything at a glance.
Reusable wallet management with clean transfer API, UTXO tracking, member resolution, and fee estimation. The building block every kdapp needs.
Model Context Protocol server that lets AI agents interact with Kaspa. The bridge between LLMs and blockchain — autonomous AI payments become possible.
Index and query Kaspa blockchain data for episode states, transaction histories, and payment records. The data layer for production applications.
Everything you need to build payment infrastructure on Kaspa. Not a theoretical whitepaper — this is the working code, architecture decisions, and battle-tested patterns from 3 months of full-time blockchain development.
Ongoing access to the full premium codebase, priority support, and a community of Kaspa builders.
Full access to all premium kdapp examples: merchant, guardian, TUI, wallet, indexer, MCP server, and more.
New examples, bug fixes, and features as the ecosystem evolves. Always stay on the cutting edge.
Private Discord channel with other KAS developers. Share patterns, debug together, ship faster.
Direct access for technical questions. Get unblocked fast when building on Kaspa.
I'm @KASperiencexyz — a developer who spent 3 months building on Kaspa, 12 hours a day, because I believe the fastest blockchain deserves real developer infrastructure.
This isn't vibe-coded throwaway code. It's battle-tested Rust that handles real payments, real disputes, and real blockchain transactions. SCC estimates the organic development cost at $2.4M — I built it with focus, AI assistance, and an obsessive commitment to doing things the right way: no mocks, no shortcuts, no fake blockchain state.
"We build on $KAS an unphishable authentication system that's sophisticated by design. The HTTP/WebSocket coordination is the secret sauce: the blockchain doesn't chat back to you directly — it's like a secure gold vault with lightning-fast stamps in a decentralized Fort Knox."
