Send coin from your own node over JSON-RPC
sendtoaddress against bitcoind, litecoind or dogecoind, with the wallet passphrase handling and the error codes that matter.
Minimum withdrawals and fees, driven by settings
Compute the fee once, show the net before they confirm, and keep every threshold in the settings table so repricing is not a code change.
