# Mempool
(*mempool*)
## Overview
### Available Operations
* [mempool](#mempool) - Get All Mempool Transactions
* [mempoolTransaction](#mempooltransaction) - Get a Mempool Transaction
## mempool
Get all Transaction Identifiers in the mempool
### Example Usage
```typescript
import { Icpmcp } from "icpmcp-rosetta-api";
const icpmcp = new Icpmcp({
serverURL: "https://api.example.com",
});
async function run() {
const result = await icpmcp.mempool.mempool({
networkIdentifier: {
blockchain: "bitcoin",
network: "mainnet",
subNetworkIdentifier: {
network: "shard 1",
metadata: {},
},
},
});
console.log(result);
}
run();
```
### Standalone function
The standalone function version of this method:
```typescript
import { IcpmcpCore } from "icpmcp/core.js";
import { mempoolMempool } from "icpmcp/funcs/mempoolMempool.js";
// Use `IcpmcpCore` for best tree-shaking performance.
// You can create one instance of it to use across an application.
const icpmcp = new IcpmcpCore({
serverURL: "https://api.example.com",
});
async function run() {
const res = await mempoolMempool(icpmcp, {
networkIdentifier: {
blockchain: "bitcoin",
network: "mainnet",
subNetworkIdentifier: {
network: "shard 1",
metadata: {},
},
},
});
if (res.ok) {
const { value: result } = res;
console.log(result);
} else {
console.log("mempoolMempool failed:", res.error);
}
}
run();
```
### Parameters

| ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
| `request` | [models.NetworkRequest](../../models/networkrequest.md) | :heavy_check_mark: | The request object to use for the request. |
| `options` | RequestOptions | :heavy_minus_sign: | Used to set various options for making HTTP requests. |
| `options.fetchOptions` | [RequestInit](https://developer.mozilla.org/en-US/docs/Web/API/Request/Request#options) | :heavy_minus_sign: | Options that are passed to the underlying HTTP request.

## mempoolTransaction
Get a transaction in the mempool by its Transaction Identifier. This is a separate request than fetching a block transaction (/block/transaction) because some blockchain nodes need to know that a transaction query is for something in the mempool instead of a transaction in a block. Transactions may not be fully parsable until they are in a block (ex: may not be possible to determine the fee to pay before a transaction is executed). On this endpoint, it is ok that returned transactions are only estimates of what may actually be included in a block.
### Example Usage
```typescript
import { Icpmcp } from "icpmcp-rosetta-api";
const icpmcp = new Icpmcp({
serverURL: "https://api.example.com",
});
async function run() {
const result = await icpmcp.mempool.mempoolTransaction({
networkIdentifier: {
blockchain: "bitcoin",
network: "mainnet",
subNetworkIdentifier: {
network: "shard 1",
metadata: {},
},
},
transactionIdentifier: {
hash: "0x2f23fd8cca835af21f3ac375bac601f97ead75f2e79143bdf71fe2c4be043e8f",
},
});
console.log(result);
}
run();
