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_CONNECT_TIMEOUT_MS="30000" # Connection timeout (default: 15000)

Core Functions

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             # Send specific amount
./kaswallet.sh send  max                # Send entire balance
./kaswallet.sh send   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

Error Handling

| Error | Cause | Solution | |-------|-------|----------| | STORAGE_MASS_EXCEEDED | Amount too small for current UTXOs | Send max to yourself first to consolidate | | NO_UTXOS | No spendable outputs | Wait for confirmations or fund wallet | | INSUFFICIENT_FUNDS | Balance too low | Check balance, reduce amount | | RPC_TIMEOUT | Network slow | Retry or increase timeout | | NO_CREDENTIALS | Missing wallet key | Set KASPA_PRIVATE_KEY or KASPA_MNEMONIC | | SDK_NOT_INSTALLED | Kaspa SDK missing | Run python3 install.py |

Common Workflows

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)

Comparison with Traditional Wallets

| Feature | Traditional Wallet | Kaspa Wallet CLI | |---------|-------------------|------------------| | Setup | GUI install | python3 install.py | | Interface | Desktop app | CLI + JSON output | | Automation | Limited | Full (JSON parsing) | | Custody | Varies | Self-custody | | Agent-friendly | No | Yes |
