# task_enable_utxo_status

After running the task::enable_utxo::init method, we can query the status of activation to check its progress. The response will return the following:

  • Result of the task (success or error)
  • Progress status (what state the task is in)
  • Required user action (what user should do before the task can continue)

# Arguments

Parameter Type Description
task_id integer The identifying number returned when initiating the initialisation process.
forget_if_finished boolean If false, will return final response for completed tasks. Optional, defaults to true.

# Command

curl --url "http://127.0.0.1:7783" --data "{
    \"userpass\": \"YOUR_PASS\",
    \"mmrpc\": \"2.0\",
    \"method\": \"task::enable_utxo::status\",

.current_block integer The block height of the coin being activated
.wallet_balance object Information about the addresses of the coin being activated
..wallet_type string In Trezor mode, this will return HD
..accounts list A list of addresses and related information for the coin being activated
...account_index integer ACCOUNT_ID child in the m/44'/COIN'/ACCOUNT_ID'/CHAIN/ADDRESS_ID BIP44 derivation path. Please don't confuse with mm2 global Iguana/HD/HW account.
...derivation_path string Derivation path up to the COIN child. E.g. "m/44'/141'/0'"

Returns Internal when CHAIN=1 in the m/44'/COIN'/ACCOUNT_ID'/CHAIN/ADDRESS_ID derivation path. External is used for addresses that are meant to be visible outside of the wallet (e.g. for receiving payments). Internal is used for addresses which are not meant to be visible outside of the wallet and is used for return transaction change.
....balance object Contains the spendable and unspendable balance for this address
