Kaspa Wallet CLI

Install

node install.js

Downloads official WASM SDK from kaspanet/rusty-kaspa.

Requires: Node.js >= 20

Environment

export KASPA_MNEMONIC="your 12-24 word seed phrase"
# or
export KASPA_PRIVATE_KEY="hex"

Optional: KASPA_NETWORK=mainnet|testnet-10

Commands

./kaswallet.sh balance [address]            # Check balance
./kaswallet.sh info                         # Network status
./kaswallet.sh send <to> <amount|max> [fee] # Send KAS
./kaswallet.sh uri [address] [amount] [msg] # Payment URI
./kaswallet.sh generate-mnemonic            # New seed phrase

Examples

# Check any address
./kaswallet.sh balance kaspa:qrc8y...

# Send 0.5 KAS
./kaswallet.sh send kaspa:qrc8y... 0.5

# Send entire balance
./kaswallet.sh send kaspa:qrc8y... max

Storage Mass Error

If you see Storage mass exceeds maximum when sending a specific amount:

Consolidate UTXOs first by sending max to your own address, then retry:

# Step 1: Get your wallet address
./kaswallet.sh balance
# Returns: {"address": "kaspa:qYOUR_ADDRESS...", ...}

# Step 2: Consolidate by sending max to yourself
./kaswallet.sh send kaspa:qYOUR_ADDRESS... max

# Step 3: Now send the specific amount (will work)
./kaswallet.sh send kaspa:qRECIPIENT... 0.5

This merges fragmented UTXOs into one, fixing the issue.

Output

All commands return JSON:

{"status":"sent","txid":"abc...","from":"kaspa:...","to":"kaspa:...","amount":"0.5","fee":"0.0002"}

Errors:

{"error":"Storage mass exceeds maximum"}
