Uniswap Deal software: Step by step
Uniswap is one of the most popular decentralized stock exchanges (Dexs) Ethereum Blockchain, allowing users to SWAPERC-20 markers ERC-20 markers. While using the Uniswap interface can be convenient, programming transactions offer greater flexibility and control over the trading process.
In this article, we will look at how to submit a software to the UnisWAP transaction without relying on the uniswap interface or automatically signing with your private key.
Prerequisites
Before you start, make sure you have:
- Compatible Ethereum purse (eg Metamak)
- Uniswap API Library for rust (or other programming language you choose
- Famousness with ERC-20 and ERC-721 markers standards
Step 1: Get Uniswap API
You will need to get the key and mystery to the UNISWAP API to submit a programmatic transaction. This can be done using the UNISWAP site or creating an account on their platform.
When you have your API credentials, you can use a library such as “Uniswap-RR” (rust) to interact with UNISWAP API.
Step 2: Set your Uniswap API
Here is an example of how to set your uniswap API rust:
`Rust
Use uniswap_rs :: {API, request, answer};
// Replace with your uniswap API key and mystery
CONST API_KEY: & Str = “Your_API_KEY”;
Const Secret: & Str = “Your_secret”;
// Create a new UNISWAP API object
Let API = API :: New (API_KEY, Secret);
`
Step 3: Define the transaction parameters
You will need to define the following parameters to submit a programmatic transaction to programmatic:
Data: Data sent in the transaction (eg marker amounts)
- Gasprice
: The price of a transaction
- Nontce
: the value of the transaction that is not CCE
Here is an example of define these parameters:
Rust
Let the data = old! [
// ERC-20 1 and ERC-20 marker 2 values ​​(eg 1 ETH and 2.5 ETH)
Data :: New (Old! [1, “ETH”], 2000000),
];
// The price of the transaction
Let Gas_price = 20000;
// The value of the transaction
Let Nonce = 0;
`
Step 4: Submit the deal
Now that you have defined the transaction parameters, it’s time to submit a transaction:
`Rust
API.Submit_transaction (
data,
Old! [Gas_price, Nece],
)
`
Code Example
Here is an example of how to submit a software to UNISWAP deal in rust:
`Rust
Use uniswap_rs :: {API, request, answer};
CONST API_KEY: & Str = “Your_API_KEY”;
Const Secret: & Str = “Your_secret”;
Fn Main () {
// Create a new UNISWAP API object
Let API = API :: New (API_KEY, Secret);
// Define the transaction parameters
Let the data = old! [
Data :: New (Old! [1, “ETH”], 2000000),
];
// The price of the transaction
Let Gas_price = 20000;
// The value of the transaction
Let Nonce = 0;
// Submit the transaction
API.Submit_transaction (
data,
Old! [Gas_price, Nece],
)
.unwrap ();
}
`
Conclusion
Submission to the Uniswap transaction without using the Uniswap interface can be achieved by defining the transaction parameters and submitting them to Uniswap API. By performing these steps, you can control the trade process with greater flexibility and accuracy.
Remember to replace your UNISWAP API key and mystery with actual values ​​and make sure you do properly in the production environment.
