Sign TSS transaction

post/api/v2/{coin}/wallet/{walletId}/signtxtss

Sign transactions for TSS wallets using external-signing mode. You must maintain your keys, in the clear, on a separate Express server. BitGo doesn't decrypt your private TSS key shares.

Path Parameters

  • coinstringRequired
    A cryptocurrency or token ticker symbol.
    Example: "btc"
  • walletIdstringRequired
    Example: "59cd72485007a239fb00282ed480da1f"
    Pattern: ^[0-9a-f]{32}$

Request Body

Any of
txRequestId string required
A unique ID for the TxRequest document across all wallets. The combination of the txRequestId and version will always be unique.
version number required
The version of the document. Data changes are done only with inserts and incrementing the version.
latest boolean required
A boolean flag that indicates whether the document is the latest version of the TxRequest.
walletId string required
The id of the Wallet the TxRequest is for.
walletType string
The type describes who owns the keys to the wallet associated to the TxRequest.
Allowed values: cold custodial custodialPaired hot trading distributedCustody
enterpriseId string
If the wallet that owns the TxRequest is owned by an enterprise then this is the Id of said enterprise.
state string required
Allowed values: initialized pendingApproval pendingUserCommitment pendingUserRShare pendingUserGShare readyToSend pendingUserSignature pendingDelivery signed delivered canceled rejected failed
date string <date-time>required
The date and time this version of the TxRequest document was created.
Example: {}
createdDate string <date-time>required
The date and time the version 1 TxRequest document was created.
Example: {}
userId string required
The Id of the User that produced this version of the TxRequest document. Could have created a new document or updated an existing document.
intentAny ofrequired
intentType string required
Allowed value: stake
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&mdash;for example, to safely retry sending. Because BitGo 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. It is the responsibility of the caller to keep track of this ID.
Example: abc123
comment string
The "comment" is only visible to users on the wallet and is not shared publicly.
nonce string
The 'nonce' of a transaction (optional)
stakingRequestId string required
poolKeyHash string required
The pool key hash to which the coins will be delegated to.
intentsrequired
intentType string required
