How ​​to Transact with Uniswap Programmatically: A Step-by-Step Guide

Uniswap is one of the most popular decentralized exchanges (DEX) on the Ethereum blockchain, allowing users to trade ERC-20 tokens for ERC-20 tokens. While using the Uniswap interface can be convenient, programmatic transactions offer more flexibility and control over the trading process.

In this article, we will cover how to programmatically send a Uniswap transaction without relying on the Uniswap interface or automatically signing with your private key.

Prerequisites

Before you begin, make sure you have:

• A supported Ethereum wallet (e.g. MetaMask)

• The Uniswap API library for Rust (or another programming language of your choice)

• Familiarity with the ERC-20 and ERC-721 token standards

Step 1: Get a Uniswap API

To programmatically send a Uniswap transaction, you will need to obtain a Uniswap API key and secret. You can do this through the Uniswap website or by creating an account on their platform.

Once you have your API credentials, you can use a library such as uniswap-rs (Rust) to interact with the Uniswap API.

Step 2: Setup your Uniswap API

Here is an example of how to setup your Uniswap API in Rust:

`rust

Step 3: Define transaction parameters
To programmatically send a Uniswap transaction, you will need to set the following parameters:
data: The data sent in the transaction (e.g. token values)
gasPrice: The gas price for the transaction
nonce: The nonce value for the transaction
Here is an example of how to set these parameters:
rust
let data = vec![
// ERC-20 token 1 and ERC-20 token 2 values ​​(e.g. 1 ETH and 2.5 ETH)
data::new(vec![1, "ETH"], 2000000),
];
// Gas price for the transaction
let gas_price = 20000;
// Nonce value for the transaction
let nonce = 0;

rust

Sample code



Here is an example of how to programmatically submit a Uniswap transaction in Rust:
`rust
use uniswap_rs::{Api, Request, Response};
const API_KEY: &str = "your_api_key";
const SECRET: &str = "your_secret";
function main() {
// Create a new Uniswap API object
let api = Api::new(api_key, SECRET);
// Set transaction parameters
let data = vec![
Data::new(vec![1, "ETH"], 2000000),
];
// Gas price for the transaction
let gas_price = 20000;
// Nonce value for the transaction
let nonce = 0;
// Submit the transaction
api.submit_transaction(
date,
vec![gas_price, nonce],
)
.unwrap();
}

Conclusion

Scheduled sending of a Uniswap transaction without using the Uniswap interface can be achieved by defining the transaction parameters and sending them to the Uniswap API. By following these steps, you will be able to control the trading process with more flexibility and precision.

Remember to replace your Uniswap API key and secret with real values ​​and make sure to handle errors properly in a production environment.
