    • Invites all connected peers to add equal-sized inputs and outputs to the PSBT
    • Asynchronous with timeout
    • This would take soem kind of settings object including:
      • Who pays the fees
      • TODO: what else
  • Mobile wallet updates outputs to according to fee settings and desired fee rate
