getrawmempool

How to use it

// yarn add @tatumio/tatum

import { TatumSDK, ZCash, Network } from '@tatumio/tatum'

const tatum = await TatumSDK.init<ZCash>({network: Network.ZCASH})

const result = await tatum.rpc.getRawMemPool(true)

await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs

Overview

The getrawmempool RPC method provides information on the transactions currently in the memory pool. This method is useful for getting details about unconfirmed transactions that have not yet been included in a block.

Parameters

• verbose (boolean, optional, default=false): Set to true to receive a detailed JSON object for each transaction in the memory pool. Set to false to receive a simple array of transaction IDs.

Example

• verbose: true

Return Object

The return object will depend on the value of the verbose parameter.

• If verbose is set to false, the method will return an array of transaction IDs.
• If verbose is set to true, the method will return an object with transaction IDs as keys and detailed transaction information as values.

Fields (when verbose is true)

• size: (numeric) The transaction size in bytes.
• fee: (numeric) The transaction fee.
• modifiedfee: (numeric) The transaction fee with descendants.
• time: (numeric) The local time when the transaction entered the memory pool.
• height: (numeric) The block height when the transaction entered the memory pool.
• descendantcount: (numeric) The number of descendant transactions in the memory pool.
• descendantsize: (numeric) The total size of all descendant transactions in the memory pool, in bytes.
• descendantfees: (numeric) The total fees of all descendant transactions in the memory pool, in satoshis.
• ancestorcount: (numeric) The number of ancestor transactions in the memory pool.
• ancestorsize: (numeric) The total size of all ancestor transactions in the memory pool, in bytes.
• ancestorfees: (numeric) The total fees of all ancestor transactions in the memory pool, in satoshis.
• wtxid: (string) The transaction witness ID.
• depends: (array) An array of unconfirmed transactions that this transaction depends on.
