SnowBlossomClient

Turn on rpcserver by running the client with the command 'rpcserver'. This is done to make sure that running the client (with full access to the wallet in question) is intentional. Requires the following config settings, rpc_port, rpc_username, rpc_password.

getfresh

Gets a fresh address. Optional parameters:

  • mark_used - (default: false) if true, mark this address as used so it will not be used as change or returned by other getfresh calls.
  • generate_now - (default: false) rather than using the unused key pool, generate a new address to use
curl -d '{ "jsonrpc": "2.0", "method":"getfresh", "id":"getfresh", "params": { "mark_used": true, "generate_now": true }}' http://cows:two@localhost:11323/
{
  "result": {
    "address": "snowtest:fxuc95w50hkpxjrkhmk3zffxdh3qsd5jkh7v8pq7",
    "mark_used": true,
    "generate_now": true
  },
  "id": "getfresh",
  "jsonrpc": "2.0"
}

balance

Get the wallet balance in both SNOW (double) and flakes.

curl -d '{ "jsonrpc": "2.0", "method":"balance", "id":"balance"}' http://cows:two@localhost:11323/
{
  "result": {
    "unconfirmed": 0,
    "spendable": 376960.914462,
    "flake_confirmed": 376960914462,
    "flake_spendable": 376960914462,
    "confirmed": 376960.914462,
    "flake_unconfirmed": 0
  },
  "id": "balance",
  "jsonrpc": "2.0"
}

send / create_transaction

Create a transaction, possible sign and broadcast snow.

  • broadcast - (default: true) broadcast transaction when done making it
  • sign - (default: true) sign transaction with any keys in current wallet that match
  • outputs - list of outputs to send snow to. Must specify snow or flakes.
  • extra - hex encoded binary data to attach as extra field to transaction

Fee related

  • fee_use_estimate - (default: true) use size based fee estimation for the fee
  • fee_flat - SNOW amount to use as the fee

Input Related

  • input_specific_list - Use only the inputs included in the input array (param: inputs)
  • input_confirmed_then_pending - (default: true) prefer to use confirmed, but use pending if run out of confirmed
  • input_confirmed_only - only use outputs that are confirmed as inputs
  • inputs - Specific list of inputs to use. each one must have, address, src_tx, src_tx_out_idx, and value

Change related

  • split_change_over - Amount of SNOW to split change outputs if in excess of
  • change_random_from_wallet - Use a random address rather than a fresh one. Note this can reuse an addresses that has been used before
  • change_fresh_address - (default: true) use a fresh address
  • change_specific_addresses - only use addresses from the list provided with 'change_addresses'
  • change_addresses - List of change addresses to use as change for this transaction

An example using an obnoxious number of features:

parse_transaction

import_wallet

Imports wallet data, in the same format used by the command line 'export', 'export_watch_only' and 'import' commands.

The format for the private key is PKCS8 encoded base64. The format for the public key is X509 encoded base64. On import, the public and private key pair are tested to make sure Snowblossom can parse them and that something signed with the private key is verified by the public key.

Example with just an address spec for watch only wallet

  "method": "import_wallet",
