# Check balance ./kaswallet.sh balance ./kaswallet.sh balance kaspa:qrc8y... # Send payment ./kaswallet.sh send kaspa:qrc8y... 0.5 ./kaswallet.sh send kaspa:qrc8y... max # Generate payment URI ./kaswallet.sh uri kaspa:q... 1.5 "coffee payment" # Network info ./kaswallet.sh info # Fee estimates ./kaswallet.sh fees # Generate new wallet ./kaswallet.sh generate-mnemonic

Architecture

Configuration

# Environment variables (one required) export KASPA_PRIVATE_KEY="64-character-hex-string" # OR export KASPA_MNEMONIC="your twelve or twenty four word seed phrase" # Optional export KASPA_NETWORK="mainnet" # mainnet (default), testnet-10 export KASPA_RPC_URL="wss://..." # Custom RPC endpoint export KASPA_RPC_CONNECT_TIMEOUT_MS="30000" # Connection timeout (default: 15000)

Check Balance

./kaswallet.sh balance # Your wallet balance ./kaswallet.sh balance kaspa:qrc8y... # Any address balance Output: {"address": "kaspa:q...", "balance": "1.5", "sompi": "150000000", "network": "mainnet"}

Send KAS

./kaswallet.sh send <address> <amount> # Send specific amount ./kaswallet.sh send <address> max # Send entire balance ./kaswallet.sh send <address> <amount> priority # Priority fee tier Output (success): {"status": "sent", "txid": "abc123...", "from": "kaspa:q...", "to": "kaspa:q...", "amount": "0.5", "fee": "0.0002"} Output (error): {"error": "Storage mass exceeds maximum", "errorCode": "STORAGE_MASS_EXCEEDED", "hint": "...", "action": "consolidate_utxos"}

Network Info

./kaswallet.sh info Output: {"network": "mainnet", "url": "wss://...", "blocks": 12345678, "synced": true, "version": "1.0.0"}

Fee Estimates

./kaswallet.sh fees Output: {"network": "mainnet", "low": {"feerate": 1.0, "estimatedSeconds": 60}, "economic": {...}, "priority": {...}}

Generate New Wallet

./kaswallet.sh generate-mnemonic Output: {"mnemonic": "word1 word2 word3 ... word24"}

Payment URI

./kaswallet.sh uri # Your address ./kaswallet.sh uri kaspa:q... 1.5 "payment" # With amount and message

┌─────────────┐ ┌─────────────┐ ┌─────────────┐ │ Sender │ │ Kaspa Wallet│ │ Recipient │ └──────┬──────┘ └──────┬──────┘ └──────┬──────┘ │ │ │ │ 1. Initiate │ │ │──────────────────▶│ │ │ │ │ │ │ 2.

Consolidate UTXOs (Fix Storage Mass Error)

When sending fails with STORAGE_MASS_EXCEEDED: # 1. Get your address ./kaswallet.sh balance # Returns: {"address": "kaspa:qYOUR_ADDRESS...", ...} # 2. Send max to yourself (consolidates UTXOs) ./kaswallet.sh send kaspa:qYOUR_ADDRESS... max # 3. Now send the original amount (will work) ./kaswallet.sh send kaspa:qRECIPIENT... 0.5

Check Transaction Status

After sending, use the txid to verify on a block explorer: Mainnet: https://explorer.kaspa.org/txs/{txid} Testnet: https://explorer-tn10.kaspa.org/txs/{txid}

Switch Networks

# Testnet export KASPA_NETWORK="testnet-10" ./kaswallet.sh info # Back to mainnet export KASPA_NETWORK="mainnet" ./kaswallet.sh info

Units

KAS: Human-readable unit (e.g., 1.5 KAS) sompi: Smallest unit, 1 KAS = 100,000,000 sompi All command inputs accept KAS. Outputs include both KAS and sompi where relevant.

Security Notes

Private keys: Never expose in logs or error messages Mnemonics: Passed via environment variables only No disk storage: Wallet does not store credentials Fresh connections: Each command establishes new RPC connection Address format: Validate Kaspa addresses (kaspa:q... format)
