How to Get Transaction History for an Address on Ethereum
Learn how to get the full transaction history for a smart contract or a user address including external, internal, token, ERC-20, ERC-721 and ERC-1155 token transfers in a single request.
API Endpoint
This tutorial uses the alchemy_getAssetTransfers endpoint.
If you just need the script for this tutorial refer to the below Recipe or continue reading for more:
A few reasons for why you'd want to get address transaction history by an address:
- Displaying your a user’s full transaction history
- Querying an address's transactions filtered by smart contract interactions
- Analyzing a user's historical profit and loss
Regardless of the different types of transaction history, you want to look up, this process can be extremely burdensome for developers to stitch together without the Alchemy Transfers API
In this tutorial, we’ll be using Alchemy’s Transfers API to fetch all transactions sent from and sent to addresses you care about to create a complete picture of a user's transaction history.
How to query transaction history
When using the Transfers API for querying a user’s full on-chain history, it's important to have a few key parameters on hand.
fromAddress: the address we want to see transaction information originating fromtoAddress: the address we want to see for recipient-based transactionsfromBlock: the starting time range we want to fetch transactions over (defaults tolatest)toBlock: the ending time range we want to fetch transactions over (defaults tolatest)category: the type of transfer events we care about, in our case we want to see all transactions so we can simply let the param use its default argument of ["external", "internal", "token"]
For transaction information that originates from your target sender address, use the fromAddress parameter within the Transfers API. For recipient-based transactions, use the toAddress parameter.
Specify from AND to address
If you want to get transactions that have a specific
fromandtoaddress, you can specify thefromAddressandtoAddressin your request.

Alchemy SDK (Recommended)
Alchemy's SDK allows us to more efficiently interact with Alchemy's endpoints and make JSON-RPC requests.
Ensure you are inside your project folder and type the following command in the terminal:
npm install alchemy-sdk
1. Create a file.
In your current directory, create a new file called tx-history-from-alchemy-sdk.js
Use your favorite file browser, code editor, or just directly in the terminal using the touch command like this:
touch tx-history-from-alchemy-sdk.js
2. Write script!
Copy and paste the following code snippet into your new file: tx-history-from-alchemy-sdk.js
// Setup: npm install alchemy-sdk
import { Alchemy, Network } from "alchemy-sdk";
const config = {
apiKey: "<-- ALCHEMY APP API KEY -->",
network: Network.ETH_MAINNET,
};
const alchemy = new Alchemy(config);
const data = await alchemy.core.getAssetTransfers({
fromBlock: "0x0",
fromAddress: "0x5c43B1eD97e52d009611D89b74fA829FE4ac56b1",
category: ["external", "internal", "erc20", "erc721", "erc1155"],
});
console.log(data);
3. Run script!
Now, on your command line, you can execute the script by calling:
node tx-history-from-alchemy-sdk.js
Node-Fetch
If you're using node-fetch a lightweight, common module that brings the Fetch API to Node.js and allows us to make our HTTP requests, here's a code snipper for the request you'd make!
1. Create a file.
In your current directory, create a new file called tx-history-from-fetch.js using your favorite file browser, code editor, or just directly in the terminal using the touch command like this:
touch tx-history-from-fetch.js
2. Write script!
Copy and paste in the following code snippet into your new file: tx-history-from-fetch.js
import fetch from 'node-fetch';
let data = JSON.stringify({
"jsonrpc": "2.0",
"id": 0,
"method": "alchemy_getAssetTransfers",
"params": [
{
"fromBlock": "0x0",
"fromAddress": "0x5c43B1eD97e52d009611D89b74fA829FE4ac56b1",
}
]
});
var requestOptions = {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: data,
redirect: 'follow'
};
const apiKey = "demo"
const baseURL = `https://eth-mainnet.g.alchemy.com/v2/${apiKey}`;
const fetchURL = `${baseURL}`;
fetch(fetchURL, requestOptions)
.then(response => response.json())
.then(response => JSON.stringify(response, null, 2))
.then(result => console.log(result))
.catch(error => console.log('error', error));
3. Run script!
node tx-history-from-fetch.js
Axios
If you're using Javascript axios, a promise-based HTTP client for the browser and Node.js which allows us to make a raw request to the Alchemy API, here's a code snipper for the request you'd make!
1. Create a file.
In your current directory, create a new file called tx-history-from-axios.js using your favorite file browser, code editor, or just directly in the terminal using the touch command.
touch tx-history-from-axios.js
2. Write script!
Copy and paste the following code snippet into your new file: tx-history-from-axios.js
import axios from 'axios';
let data = JSON.stringify({
"jsonrpc": "2.0",
"id": 0,
"method": "alchemy_getAssetTransfers",
"params": [
{
"fromBlock": "0x0",
"fromAddress": "0x5c43B1eD97e52d009611D89b74fA829FE4ac56b1",
}
]
});
var requestOptions = {
method: 'post',
headers: { 'Content-Type': 'application/json' },
data: data,
};
const apiKey = "demo"
const baseURL = `https://eth-mainnet.g.alchemy.com/v2/${apiKey}`;
const axiosURL = `${baseURL}`;
axios(axiosURL, requestOptions)
.then(response => console.log(JSON.stringify(response.data, null, 2)))
.catch(error => console.log(error));
3. Run script!
Now, on your command line, you can execute the script by calling:
node tx-history-from-axios.js

Printing out the asset and value
asset and valueTwo of the many different response objects you may be interested in parsing are: asset and value.
Let's walk through an example that parses the returned JSON object.
Whether we're querying via alchemy web3, axios, or node-fetch, we'll need to save the queried response object into a constant.
Alchemy SDK (Recommended)
Saving response objects with Alchemy SDK
Alchemy SDK// Alchemy SDK
const res = await alchemy.core.getAssetTransfers({
fromBlock: "0x0",
toAddress: "0x5c43B1eD97e52d009611D89b74fA829FE4ac56b1",
category: ["external", "internal", "erc20", "erc721", "erc1155"],
})
Node-Fetch
Saving response objects with Node-Fetch
Node-Fetch// Node-Fetch
fetch(fetchURL, requestOptions)
.then((res) => {
return res.json()
})
.then((jsonResponse) => {
//Print token name / asset value
for (const events of jsonResponse.result.transfers) {
console.log("Token Transfer: ", events.value, " ", events.asset);
}
})
.catch((err) => {
// handle error
console.error(err);
});
Axios
Saving response objects with Axios
Axios// Axios
const res = await axios(axiosURL, requestOptions);
With our queried response object saved as a constant, we can now index through the transfers.
In particular, the steps we take are:
- Loop through all transfers in the result
- Print each element's
valueandassetfield
// Print token asset name and its associated value
for (const events of res.data.result.transfers) {
console.log("Token Transfer: ", events.value, " ", events.asset);
}
If you followed along, your response should look like the following:
Token Transfer: 0.5 ETH
Token Transfer: 0.27 ETH
Token Transfer: 9.90384 ETH
Token Transfer: 0.07024968 ETH
Token Transfer: 0.000447494250654841 ETH
Token Transfer: null null
Token Transfer: 0.075 ETH
Token Transfer: 0.003 ETH
Token Transfer: null BURN
Token Transfer: 54 DAI
Token Transfer: 12.5 GTC
Token Transfer: 2 GTC
Token Transfer: 0.42 ETH
........
Token Transfer: 0.588 WETH
Token Transfer: null null
Token Transfer: null null
Token Transfer: 2.3313024 ETH
Token Transfer: 0.0633910153108353 ETH
