Consolidate unspents (advanced)

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

Build a transaction to consolidate unspents in a wallet. Once built, you must sign and sent the transaction. Consolidating unspents is only for UTXO-based assets.

Path Parameters

  • coinstringRequired
    A cryptocurrency or token ticker symbol.
    Example: btc
  • walletIdstringRequired

Request Body

feeRateOne of
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`.
Example: null
maxFeeRateOne of
(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`.
Example: null
Match pattern: ^-?\d+$
maxFeePercentage integer
Maximum relative portion that can be spent towards fees
feeTxConfirmTarget integer
Block target for fee estimation
bulk boolean
Build multiple transactions at the same time. This enables you to increase the maximum number of unspents on the `limit` parameter up to 2,000. If true, you must pass the `txFormat` as `psbt` and you can't pass the `targetAddress` or `numUnspentsToMake` parameters.
minValueOne of
Minimum value of unspents to use in base units (e.g. satoshis). Can be used to skip very small unspents when consolidating at higher fee rates. For doge, only string is allowed.
Example: 2000000
Match pattern: ^-?\d+$
maxValueOne of
Maximum value of unspents to use in base units (e.g. satoshis). Should be used to prevent larger unspents from being consolidated needlessly, and that some funds remain available for spending while the consolidation transactions are in flight. For doge, only string is allowed.
Example: 2000000
Match pattern: ^-?\d+$
minHeight integer
Minimum height of unspents on the block chain to use
minConfirms integer
Minimum confirmation threshold for external inputs
enforceMinConfirmsForChange boolean
Flag for enforcing minConfirms for change inputs
limit integer
Maximum number of unspents to use in the transaction
numUnspentsToMake integer
Number of new unspents to make
targetAddress string
address to use for generated outputs. Must be wallet address.
txFormat string
[UTXO only] Format of the returned transaction hex serialization. `legacy` for serialized transaction in custom bitcoinjs-lib format. `psbt` for BIP174 serialized transaction
Allowed values: legacy psbt psbt-lite
Default: legacy
Example: psbt

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. 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 or a flat 1000 microAlgos).
Example: null
