Ethereum: Receiving money in Regression Test Mode (Regtest)
When developing an application that interacts with a bitcoin server to obtain details of transactions of transaction ID transactions, it is necessary to consider the use of Ethereum for other features. One such case of use is to receive money through Regtest mode that allows you to test and verify your app without revealing your wallet on the main network. Here is an article on how to get funds in Regtest mode in Ethereum.
What is Regression Test Mode?
The regression mode (Regtest) simulates a transaction with the same transaction ID as used to create it in the main hall, but without actually sending or accepting any means. This will help you verify that your code is behaving correctly and there is no errors that could appear after deployment.
Setting Ethereum for Regtest mode
Before you continue, make sure you have Node.JS, Geth (client Go Ethereum) and truffle package on your computer.
assumptions
- Install the required packages:
– npm install @coarse/core oryarn add tuber Core
– npm install @coarse/compile oryarn add Compile
- Create a new project with
NPX Truffle Init
- Configure your Mainnet and Regtest networks in the
.envfile.
Configuration of your Ethereum network
You will need to update your network configuration in config/contonce.json. Make sure you have the following setting:
`json
{
“Network”: {{
“Mainnet”: True,
“Regtest”: False,
“RPC”: “
“ETH1”: {{
“RPC”: “
},
}
}
`
Replace your_project_id for your actual infura project.
Creating a contract to receive funds
Create a new file called SRC/Contract/Reccipient.sol. Here is an example of a contract:
`Solidity
Pragma of solidity ^0.8.0;
Import “
Import “
The recipient of the contract {
Use Safeerc20 for (ERC20.ierc20);
ERC20 Public Payment;
Constructor (address _Payable) {
Payable = ERC20 (_Payable);
}
The function accepts () public payments (BOOL) {
Return Pravda;
}
}
`
Testing contract with Regtest
If you want to test your contract without actually sending or receiving funds, you can use a combination of commands:
- Run the Geth knot:
`Bash
GO Launch –NODE = 127.0.0.1: 8545 ./SRC/Contract/recip
`
- Build and deploy your intelligent contract to the Ethereum network.
- Use the “Compile” Truffle command to compile and update the contract in the local Regtest.
For example::
`Bash
Composition of truffles NPX
Truffle Migration -siete = Regtest
`
Receiving funds through Regtest Mode
After successful deployment and updating of your intelligent contract, you can test the receipt of funds via Regtest. As follows:
1.
`Bash
GO Launch –NODE = 127.0.0.1: 8545 ./SRC/Contract/recip
`
- Create a new transaction that calls your contract and sends funds:
`Solidity
Pragma of solidity ^0.8.0;
Import “
Import “
The recipient of the contract {
Use Safeerc20 for (ERC20.ierc20);
ERC20 Public Payment;
Constructor (address _Payable) {
Payable = ERC20 (_Payable);
}
The function accepts () public payments (BOOL) {
Return Pravda;
}
}
Pragma of solidity ^0.8.0;
