## Properties

### adjustedVsize

> **adjustedVsize**: `number`

Defined in: [Developer/brk/modules/brk-client/index.js:430](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L430)

Policy-adjusted virtual size: `max(vsize, sigops * 5)`.

***

### ancestors

> **ancestors**: [`CpfpEntry`](CpfpEntry.md)[]

Defined in: [Developer/brk/modules/brk-client/index.js:420](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L420)

Ancestor transactions in the CPFP chain.

***

### bestDescendant?

> `optional` **bestDescendant?**: [`CpfpEntry`](CpfpEntry.md) \| `null`

Defined in: [Developer/brk/modules/brk-client/index.js:421](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L421)

Best (highest fee rate) descendant, if any.

***

### cluster?

> `optional` **cluster?**: [`CpfpCluster`](CpfpCluster.md) \| `null`

Defined in: [Developer/brk/modules/brk-client/index.js:431](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L431)

Cluster the seed belongs to: full tx list, SFL-linearized chunks,
and the seed's chunk index. Omitted when the seed has no
ancestors and no descendants (matches mempool.space).

***

### descendants

> **descendants**: [`CpfpEntry`](CpfpEntry.md)[]

Defined in: [Developer/brk/modules/brk-client/index.js:422](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L422)

Descendant transactions in the CPFP chain.

***

### effectiveFeePerVsize

> **effectiveFeePerVsize**: `number`

Defined in: [Developer/brk/modules/brk-client/index.js:423](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L423)

Effective fee rate considering CPFP relationships (sat/vB).
This is the seed's chunk feerate after lift-merging, i.e. the
rate Core/mempool.space would surface for this tx.

***

### fee

> **fee**: `number`

Defined in: [Developer/brk/modules/brk-client/index.js:428](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L428)

Transaction fee (sats).

***

### sigops

> **sigops**: `number`

Defined in: [Developer/brk/modules/brk-client/index.js:426](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L426)

BIP-141 sigop cost for the seed tx (witness sigops count as 1,
legacy and P2SH-redeem sigops count as 4).

***

### vsize

> **vsize**: `number`

Defined in: [Developer/brk/modules/brk-client/index.js:429](https://github.com/bitcoinresearchkit/brk/blob/25b226856307047c5c10a075ec57219ca9987c38/modules/brk-client/index.js#L429)

Virtual size of the seed tx (vbytes).
