Gas estimate error in the program Sending 20 ERC chips with dispersion
Ethereum smart agreements have become an important part of every blockchain development project. However, one of the common problems that may occur when implementing and launching smart program contracts is a gas estimation error that can result from sending large amounts of data into the Ethereum network.
In this article, we will discuss how to estimate the cost of intelligent gas implementation using dispersion, a popular decentralized application (DAPP) platform for ETHREUM -based applications. In particular, we will focus on a common scenario, in which many ERC chips are sent programmatically to various portfolios.
Gas estimate error
When sending data to the Ethereum network, such as sending 20 ERC chips from a wallet to many other wallets, a gas estimate error may occur for several reasons:
1.
- Gas prices
: Gas prices are higher than the current market rate, which makes the transaction more gas than necessary.
Distributed Solution: Estimated Gas Cost
In order to estimate the cost of intelligent implementation of the contract using disappears, we can use the “gasestimator” function, which ensures that the estimated cost of the implementation gas and cause a specific function. In our case, we will use it to estimate the costs of sending 20 ERC chips from a wallet to many other wallets.
Code fragment
Here is an example of a fragment of the code that shows how to use the “Gasestimator Disperser” function:
“ Solidity
Pragma solidity ^0.8.0;
The MySmartContract Agreement {
// function of the section of 20 ERC chips for many wallets
The transfertokestopti function (recipient address []) public {
Gasestimator (
“Transferkestopti”,
“MySmartContract”,
“Mytoken”,
(Address (_recicipynt), uint256 (_amount) => _recicipynt,
_Gas, // requested gase estimation for the function
_Maxgas // Maximum gas cost per transaction
).result(
“Move”,
True, // the successful flag
“_Success”, // the message of the results
_Gascost // Gaz costs estimated in Wei
);
// transfer tokens to each recipient
for (uint256 i = 0; i
Transferans (_Tokenaddress, recipient [i], _amount);
}
}
// section of 20 ERC chips from a wallet to many other wallets
Transfertokens function (address source, address destination, UNT256) internal {
// Calculate gas costs for transfer operations
UINT256 GASCOST = calculate races (source, destination, amount);
// Move the chips using the dispersed function “Transfer”
The result of transfersult = dispersrransfer (source, destination, amount);
requires (result.status == 0x00, “unsuccessful transfer”);
}
// function to estimate the cost of intelligent gases by dispersion
Calculated Function Gascost (address source, address destination, UNT256) internal phrases (UNT256) {
// Call the “Gasestimator” function with dispersion
The return of the gasestimator (
“Transferkestopti”,
“MySmartContract”,
“Mytoken”,
(Address (_recicipynt), uint256 (_amount) => _recicipynt,
0, // the desired estimation of the intelligent contract implementation gases
2000000 // Maximum admitted the cost of gas to connect the function
)
