  4. Fetch UTXOs from WhatsOnChain
  5. Build transaction with P2PKH inputs/outputs

Error Handling

  • Invalid WIF: Clear error with SDK message
  • Invalid address: Format validation error
  • Insufficient funds: Shows balance vs required amount
  • Network errors: Displays raw tx hex for manual broadcast

Network

Uses BSV mainnet via WhatsOnChain API:

  • UTXOs: GET /v1/bsv/main/address/{address}/unspent
  • Broadcast: POST /v1/bsv/main/tx/raw
