wallet-send-bsv

Wallet Send BSV

Build, sign, and broadcast a P2PKH payment from a WIF private key using @bsv/sdk.

Note: This skill is for WIF-key-based scripts and CLIs. If building an app where users have their own wallet, use wallet-brc100 with WalletClient.createAction() instead — the wallet handles UTXOs, signing, and broadcasting automatically.

When to Use

• Scripts and CLIs that own a WIF private key
• Server-side BSV payments from a managed key
• Quick one-off transfers from a known address

Usage

bun run skills/wallet-send-bsv/scripts/send.ts <from-wif> <to-address> <amount-satoshis>

# Show help
bun run skills/wallet-send-bsv/scripts/send.ts --help

# Example: Send 1000 satoshis
bun run skills/wallet-send-bsv/scripts/send.ts L1abc... 1BvBMSEY... 1000

Arguments

Argument	Description
from-wif	Private key in WIF format (starts with K, L, or 5)
to-address	Recipient BSV address (starts with 1 or 3)
amount-satoshis	Amount to send (1 BSV = 100,000,000 satoshis)

Dependencies

• @bsv/sdk - BSV SDK for key/transaction operations
• WhatsOnChain API - UTXO fetching
• GorillaPool ARC - Transaction broadcast

Transaction Flow

1. Parse and validate WIF private key
2. Validate recipient address format
3. Derive sender address from private key
4. Fetch UTXOs from WhatsOnChain
5. Build transaction with P2PKH inputs/outputs
6. Calculate fee (1 sat/byte)
7. Sign transaction
8. Broadcast via GorillaPool ARC (https://arc.gorillapool.io)

Error Handling

• Invalid WIF: Clear error with SDK message
• Invalid address: Format validation error
• Insufficient funds: Shows balance vs required amount
• Broadcast failure: Shows ARC error code and description

Related Skills

• broadcast-arc — broadcast any signed transaction via ARC (GorillaPool or TAAL)
• wallet-brc100 — app-level payments via WalletClient (no WIF needed)
• decode-bsv-transaction — inspect a transaction before broadcasting
