• type string

  Required for transactions from MPC wallets. "acceleration" speeds up transactions with a certain nonce by adjusting the gas setting. "accountSet" is for XRP AccountSet transactions. "consolidate" combines multiple UTXO inputs into fewer outputs. "enabletoken" is for SOL. "fanout" splits UTXO inputs into many smaller outputs (UTXO coins only). "stakingLock" and "stakingUnlock" are for Stacks delegations. "transfer" is for native-asset transfers. "trustline" is for Stellar trustline transactions. Possible types include: [acceleration, accountSet, consolidate, enabletoken, fanout, stakingLock, stakingUnlock, transfer, transfertoken, trustline]

• messages array of objects
  [UTXO only] An array of messages that you sign with the wallet keys using the BIP322 format. If passed, the recipients array must be empty.
  messages object

  • address string
    The address for which you're proving ownership. This address must belong to the wallet.
  • message string
    Message that is being signed.
• numBlocks integer

  (BTC only) The number of blocks required to confirm a transaction. You can use numBlocks to estimate the fee rate by targeting confirmation within a given number of blocks. If both feeRate and numBlocks are absent, the transaction defaults to 2 blocks for confirmation.

  Note: The maxFeeRate limits the fee rate generated by numBlocks.

  >= 2 · <= 1000
• feeRate string or integer

  Custom fee rate (in base units) per kilobyte (or virtual kilobyte). For example, satoshis per kvByte.

  If the feeRate is less than the minimum required network fee, then the minimum fee applies. For example, 1000 sat/kvByte, a flat 1000 microAlgos, or a flat 10 drops of xrp. For XRP, the actual fee is usually 4.5 times the open ledger fee.

  Note: The feeRate overrides the maxFeeRate and minFeeRate.
• maxFeeRate string or integer

  (BTC only) The maximum fee rate (in base units) per kilobyte (or virtual kilobyte). For example, satoshis per kvByte. The maxFeeRate limits the fee rate generated by both feeMultiplier and numBlocks.

  Note: The feeRate overrides the maxFeeRate.
• feeMultiplier string or number

  (UTXO only) Custom multiplier to the feeRate. The resulting fee rate is limited by the maxFeeRate. For replace-by-fee (RBF) transactions (that include rbfTxIds), the feeMultiplier must be greater than 1, since it's an absolute fee multiplier to the transaction being replaced.

  Note: The maxFeeRate limits the fee rate generated by feeMultiplier.
• minConfirms integer
  The unspent selection for the transaction will only consider unspents with at least this many confirmations to be used as inputs. Does not apply to change outputs unless used in combination with enforceMinConfirmsForChange.
• enforceMinConfirmsForChange boolean
  When set to true, will enforce minConfirms for change outputs. Defaults to false.

  Defaults to false

  False True
• gasPrice string or integer
  Custom gas price to be used for sending the transaction. Only for ETH and ERC20 tokens.
• eip1559 object
  eip1559 object

  • maxPriorityFeePerGas string or integer
    Max priority tip price for EIP1559 transactions. Only for ETH and ERC20 tokens.
  • maxFeePerGas string or integer
    Max total gasPrice for EIP1559 transactions. Only for ETH and ERC20 tokens.
• gasLimit string or integer
  Custom gas limit to be used for sending the transaction. Only for ETH and ERC20 tokens.
• targetWalletUnspents integer

  Specifies the minimum count of good-sized unspents to maintain in the wallet. Change splitting ceases when the wallet has targetWalletUnspents good-sized unspents.

  Note: Wallets that continuously send a high count of transactions will automatically split large change amounts into multiple good-sized change outputs while they have fewer than targetWalletUnspents good-sized unspents in their unspent pool. Breaking up large unspents helps to reduce the amount of unconfirmed funds in flight in future transactions, and helps to avoid long chains of unconfirmed transactions. This is especially useful for newly funded wallets or recently refilled send-only wallets.

  Defaults to 1000
• minValue string or integer
  Ignore unspents smaller than this amount of base units (e.g. satoshis). For doge, only string is allowed.
• maxValue string or integer
  Ignore unspents larger than this amount of base units (e.g. satoshis). For doge, only string is allowed.
• sequenceId string
  A sequenceId is a unique and arbitrary wallet identifier applied to transfers and transactions at creation. It is optional but highly recommended. With a sequenceId you can easily reference transfers and transactions—for example, to safely retry sending. Because the system only confirms one send request per sequenceId (and fails all subsequent attempts), you can retry sending without the risk of double spending. The sequenceId is only visible to users on the wallet and is not shared publicly.
• nonce string
  (DOT only) A nonce ID is a number used to protect private communications by preventing replay attacks. This is an advanced option where users can manually input a new nonce value in order to correct or fill in a missing nonce ID value.
• noSplitChange boolean

  Set true to disable automatic change splitting.

  Also see: targetWalletUnspents

  Defaults to false

  False True
• unspents array of strings
  Used to explicitly specify the unspents to be used in the input set in the transaction. Each unspent should be in the form prevTxId:nOutput.
