Kaspa Dev

Comprehensive Kaspa blockchain development toolkit for building transactions, integrating wallets, creating dApps, block explorers, and interacting with the Kaspa network. Use when working with Kaspa blockchain development including: (1) Building and broadcasting transactions, (2) Generating addresses and managing wallets, (3) Creating dApps or block explorers, (4) Integrating Kaspa into existing applications (RainbowKit, OisyWallet, etc.), (5) Working with KRC20 tokens, (6) Setting up Kaspa nodes, (7) Using Kaspa SDKs (Rust, Go, JavaScript/TypeScript, Python, WASM). Supports Rust, Go, JavaScript/TypeScript, Python, and Motoko (Internet Computer) development.

Overview

This skill provides comprehensive support for Kaspa blockchain development across multiple programming languages and use cases. Whether you're building a simple wallet integration, a full dApp, a block explorer, or working with KRC20 tokens, this skill provides the patterns, SDK references, and boilerplate code you need.

Choose Your SDK

Kaspa provides official SDKs for multiple languages: JavaScript/TypeScript: kaspa-wasm - WebAssembly-based SDK for browser and Node.js Rust: kaspa-rpc-client and kaspa-wallet-core - Native Rust SDK Go: github.com/kaspanet/kaspad - Official Go implementation Python: Community SDKs available via PyPI Motoko: kaspa package on Mops for Internet Computer integration

Common Tasks

Generate a Kaspa Address JavaScript/TypeScript: import { PrivateKey, NetworkType } from 'kaspa-wasm'; const privateKey = PrivateKey.random(NetworkType.Mainnet); const publicKey = privateKey.toPublicKey(); const address = publicKey.toAddress(NetworkType.Mainnet); console.log('Address:', address.toString()); console.log('Private Key:', privateKey.toString()); Rust: use kaspa_wallet_core::keys::{PrivateKey, PublicKey}; use kaspa_consensus_core::network::NetworkType; let private_key = PrivateKey::random(NetworkType::Mainnet); let public_key = private_key.to_public_key(); let address = public_key.to_address(NetworkType::Mainnet); println!("Address: {}", address.to_string()); Go: import ( "github.com/kaspanet/kaspad/domain/consensus/model/externalapi" "github.com/kaspanet/kaspad/util" ) privateKey, _ := util.GeneratePrivateKey() publicKey := privateKey.PublicKey() address, _ := util.NewAddressPublicKey(publicKey.Serialize(), util.Bech32PrefixKaspaMain) fmt.Printf("Address: %s\n", address.String()) Build and Broadcast a Transaction JavaScript/TypeScript: import { Transaction, RpcClient, NetworkType } from 'kaspa-wasm'; const rpc = new RpcClient({ url: 'wss://api.kaspa.org', network: NetworkType.Mainnet }); await rpc.connect(); // Get UTXOs for the sender address const utxos = await rpc.getUtxosByAddresses([senderAddress]); // Build transaction const tx = new Transaction({ version: 0, inputs: utxos.map(utxo => ({ previousOutpoint: utxo.outpoint, signatureScript: '', // Will be filled after signing sequence: 0, sigOpCount: 1 })), outputs: [{ amount: amount, scriptPublicKey: recipientScriptPublicKey }], lockTime: 0, subnetworkId: '00000000000000000000000000000000' }); // Sign transaction const signedTx = await signTransaction(tx, privateKey); // Broadcast const txId = await rpc.submitTransaction(signedTx); console.log('Transaction ID:', txId);

SDK References

For detailed SDK documentation and examples: JavaScript/TypeScript (WASM): See references/kaspa-wasm-sdk.md Rust SDK: See references/kaspa-rust-sdk.md Go SDK: See references/kaspa-go-sdk.md Python SDK: See references/kaspa-python-sdk.md API Reference: See references/api-reference.md for Kaspa Developer Platform API

Wallet Integration

For integrating Kaspa into wallets like RainbowKit, OisyWallet, or custom wallets: See references/wallet-integration.md for: Wallet connection patterns Transaction signing flows Address management Network switching

Node Operations

For setting up and operating Kaspa nodes: See references/node-operations.md for: Docker deployment Binary installation Building from source Configuration options RPC node setup Monitoring and maintenance

dApp Development

When building a Kaspa dApp: Setup: Use the WASM SDK for browser compatibility Wallet Connection: Implement wallet adapter pattern State Management: Track balances, transactions, and UTXOs Transaction Building: Use UTXO selection algorithms Error Handling: Handle network failures and reorgs

Block Explorer

To build a block explorer: Data Source: Use Kaspa Developer Platform API or run your own node Indexing: Index blocks, transactions, and addresses API Layer: Build REST/GraphQL API for frontend Frontend: Display blocks, transactions, addresses, and network stats See API reference for available endpoints.

KRC20 Tokens

Kaspa supports KRC20 tokens (similar to ERC20 on Ethereum). For token development: See references/krc20-tokens.md for: Token contract structure Transfer and approval mechanisms Token metadata Integration patterns

Network Types

Kaspa has three network types: Mainnet: Production network (prefix: kaspa:) Testnet: Testing network (prefix: kaspatest:) Devnet: Development network (prefix: kaspadev:) Always use the correct network type for your use case.

Address Formats

Kaspa uses Bech32 encoding for addresses: Mainnet: kaspa:qqkqkzjvr7zwxxmjxjkmxx (62 characters total) Testnet: kaspatest:qqkqkzjvr7zwxxmjxjkmxx Devnet: kaspadev:qqkqkzjvr7zwxxmjxjkmxx

Scripts and Utilities

The scripts/ directory contains utility scripts: generate-address.py: Generate Kaspa addresses build-transaction.py: Build and sign transactions monitor-address.py: Monitor address for incoming transactions

Assets

The assets/ directory contains boilerplate templates: dapp-template/: React/Next.js dApp starter explorer-template/: Block explorer starter wallet-adapter/: Wallet adapter implementation

Best Practices

Always validate addresses before using them Handle UTXO selection carefully to avoid dust outputs Implement proper error handling for network failures Test on testnet before mainnet deployment Monitor for chain reorganizations when confirming transactions Use fee estimation for timely transaction confirmation Secure private keys - never expose them in client-side code
