Build chain transactions. To solve the problem of excessive utxo causing the transaction to fail, the utxo merge will be performed automatically. Currently, only btm transactions are supported.Warning, this feature requires the mine pool bytomd software to be higher than v1.0.6.

Parameters

Object:

• String - base_transaction, base data for the transaction, default is null.
• Integer - ttl, integer of the time to live in milliseconds, it means utxo will be reserved(locked) for builded transaction in this time range, if the transaction will not to be submitted into block, it will be auto unlocked for build transaction again after this ttl time. it will be set to 5 minutes(300 seconds) defaultly when ttl is 0.
• Integer - time_range, time stamp(block height)is maximum survival time for the transaction, the transaction will be not submit into block after this time stamp.
• Arrary of Object - actions:
  • Object:
    • String - account_id | account_alias, (type is spend_account) alias or ID of account.
    • String - asset_id | asset_alias, (type is spend_account, issue, retire, control_program and control_address) alias or ID of asset.
    • Integer - amount, (type is spend_account, issue, retire, control_program and control_address) the specified asset of the amount sent with this transaction.
    • String- type, type of transaction, valid types: 'spend_account', 'issue', 'spend_account_unspent_output', 'control_address', 'control_program', 'retire'.
    • String - address, (type is control_address) address of receiver, the style of address is P2PKH or P2SH.
    • String - control_program, (type is control_program) control program of receiver.
    • String - use_unconfirmed, (type is spend_account and spend_account_unspent_output) flag of use unconfirmed UTXO, default is false.
    • Arrary of Object - arguments, (type is issue and spend_account_unspent_output) arguments of contract, null when it's not contract.
      • String- type, type of argument, valid types: 'raw_tx_signature', 'data'.
      • Object- raw_data, json object of argument content.
        • String- xpub, (type is raw_tx_signature) root xpub.
        • String- derivation_path, (type is raw_tx_signature) derived path.
        • String- value, (type is data) string of binary value.

Returns

• String - status, status information
• Object-data
  • Object - raw_transaction, builded transactions.
  • Object - signing_instructions,Information used to sign a transactions.

Example

• spend - transaction type is spend
