Build a transaction from the wallet using provided options. Use only with multisignature wallets. For TSS wallets, use Create transaction request. If you want to build, sign, and send all in one call, use Send transaction.
Path Parameters
coinstringRequired
A cryptocurrency or token ticker symbol.
Example: "btc"

Query Parameters
destinationTagstring
Required when sending to a BitGo wallet.
Request Body
One of
typestring
Required for transactions from TSS wallets. "acceleration" speeds up transactions with a certain nonce by adjusting the gas setting. "accountSet" is for XRP AccountSet transactions. "enabletoken" is for SOL. "stakingLock" and "stakingUnlock" are for Stacks delegations. "transfer" is for native-asset transfers. "trustline" is for Stellar trustline transactions. Possible types include: [acceleration, accountSet, enabletoken, stakingLock, stakingUnlock, transfer, transfertoken, trustline]
For AVAX only, possible types include: [addValidator, export, import]
numBlocksinteger
(BTC only) Used to estimate the fee rate by targeting confirmation within the given number of blocks. If neither "feeRate" nor "numBlocks" is specified, a block target of 2 is used by default. Can be limited with "maxFeeRate".
Minimum: >= 2
Maximum: <= 1000
feeRateOne of
Custom minimum fee rate in a coin's base unit per kilobyte (or virtual kilobyte)--for example, satoshis per kvByte or microAlgos per kByte. For xrp, it refers to the open ledger fee in drops (1 XRP = 1000000 drops) and the actual fee used is usually 4.5 times the open ledger fee. If the applied "feeRate" does not meet a coin's required minimum transaction fee amount, the minimum is still applied (for example, 1000 sat/kvByte , a flat 1000 microAlgos or a flat 10 drops of xrp).
maxFeeRateOne of
Custom upper limit for fee rate in a coin's base unit per kilobyte (or virtual kilobyte)--for example, satoshis per kvByte or microAlgos per kByte. "maxFeeRate" can be used to limit a fee rate estimate generated with "numBlocks".
feeMultiplierOne of
Custom multiplier for fee rate. Suggested to be used in conjunction with "maxFeeRate" for higher priority transactions, or transactions which may not be broadcast for some time after being built. Must be greater than 0.
minConfirmsinteger
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".
enforceMinConfirmsForChangeboolean
When set to true, will enforce minConfirms for change outputs. Defaults to false.
Default: false
gasPriceOne of
Custom gas price to be used for sending the transaction. Only for ETH and ERC20 tokens.
eip1559object
maxPriorityFeePerGasOne of
maxFeePerGasOne of
Max total gasPrice for EIP1559 transactions. Only for ETH and ERC20 tokens.
gasLimitOne of
Custom gas limit to be used for sending the transaction. Only for ETH and ERC20 tokens.
targetWalletUnspentsinteger
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.
Default: 1000
minValueOne of
Ignore unspents smaller than this amount of base units (e.g. satoshis). For doge, only string is allowed.
maxValueOne of
Ignore unspents larger than this amount of base units (e.g. satoshis). For doge, only string is allowed.
sequenceIdstring
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.
noncestring
(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.
Example: 2000000
Match pattern: ^-?\d+$
noSplitChangeboolean
Set "true" to disable automatic change splitting.
Also see: "targetWalletUnspents"
Default: false
unspentsarray[string]
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".
changeAddressstring
Specifies a custom destination address for the transaction's change output(s)
Max length: <= 250 characters
Example: 2MvrwRYBAuRtPTiZ5MyKg42Ke55W3fZJfZS
instantboolean
(DASH only) Specifies whether or not to use Dash's "InstantSend" feature when sending a transaction.
memoobject
Memo for Stellar or EOS. Type is only required for memos in Stellar transactions. The memo contains optional extra information that can also be used to identify payments in Stellar or EOS.
typestring
valuestring
commentstring
Optional metadata (only persisted in BitGo) to be applied to the transaction. Use this to add transaction-specific information such as the transaction's purpose or another identifier that you want to reference later. The value is shown in the UI in the transfer listing page.
Max length: <= 256 characters
destinationChainstring
(AVAXC and AVAXP only) Destination chain for an AVAX import/export transaction. One of [P, C].
sourceChainstring
(AVAXC and AVAXP only) Source chain for an AVAX import/export transaction. One of [P, C].
