Understanding the prize of pairs of pool Uniswap V3
The UNISWAP V3 Fund Prices are aspect of blockchain trafficking Ethereum. However, navigating pair calculations can be difficult. In this article, we will examine how to determine the correct plots from the Uniswap V3 funds and the common problems of DDDRESS that have token.
Ethereum 2.x update: Calculation of prices **
In November 2021, the Ethereum 2.0 update introduced a new model for UNISWAP V3 funds. The updated formula calculates this change in the “Uniswapv3Router” contraction.
Problem: inconsistent formatting of tokens price
When calculating pair prices, you can get the Incunter InconSist to format for problems with tokens prices. Specifically:
- Price token is not displayed correctly :
- Unusual negative Walues : Inconsistent or unusual negative Walues are token.
troubleshooting
To solve the problems you can follow the steps of Thees:
Step 1: Get the “Uniswapv3RouterPair” contract
First, get “Uniswapv3Router” a contracted address from the Uniswap V3 or BI by causing decentralized (Dex) as OpenSE.
Step 2: Get a token price in the expected format
Use the_getbalance feature to get you to calculate the information
`Solidity
Pragma of solidity ^0.8.0;
Contract from UniswapV3ROUTERPAIR {
// … (the rest of the contraction remains soam)
Functione Getbalance () Public view returns (balance Uint256) {
// … (Get the Token Balance)
uint256 price = 1 ether;
repayable balance * Price; // Assuming a fixed price for simplicity
}
Function Calculation PriceinusDC (Balance Uint256, Delivery Uint256) Internal returns (Uint256 USDCBALANCE) {
// Calculate the price in USDC Use an updated formula
uint256 tokenpriceineth = 1 ether;
UInt256 tokensupply = power supply; // provided it is a fixed van for simplicity
uint256 USDCPRICE = Bilant * tokenpriceineth / tokensupply;
USDCPRICE return;
}
}
`
Step 3: Integrate code without Uniswap V3
You can now integrate “Getbalance” into your fund to load a token for format:
`Solidity
Pragma of solidity ^0.8.0;
Mypool contract {
// … (the rest of the contraction remains soam)
Strokt token {
UINT256 balance; // 1 ether
Delivery Uint256;
}
Token private token;
The Interbalance () function returns public view (Uint256) {
Return token.balancia;
}
Function Calculation PriceinusDC (Balance Uint256, Delivery Uint256) Internal returns (Uint256 USDCBALANCE) {
Return Getbalance () * 1 ether / delivery; // Assuming a fixed price for simplicity
}
}
`
Step 4: Test your code
Test your code by sending tokens tokens tokens to the fund and verify that they are price. You can use a test frame such as OpenZepelin supplier.
By monitoring the flows you should be a) Be sure to replace the “Getbalance” feature for your real implementation, it is an update and for calculating the calculation calculation.
More tips
- Create a recent strength (1.0.0 or later) as repairs related to token calculations.
- Be aware that the solutions have assumed that it is necessary for simplicity, it is time scenarios in the real world.
