This dapp implements a "Hello World" style application that echoes a message passed to the contract to the front end. This tutorial is intended to be followed using the online IDE available at Remix IDE.
Remix is an online IDE to develop smart contracts.
You need to choose Solidity Compiler and Deploy and Run Transactions
Go to File Explorers, And Create a new file, Name it MegaCoin.sol
Copy/Paste the Smart contract below into the newly created file MegaCoin.sol
Create new contract ECT20Token.sol and copy contract code from the ECT20 token template here
Modify “name”, “symbol”, “decimals” and “totalSupply” according to your requirements.
The first line, pragma solidity ^0.5.16 specifies that the source code is for a Solidity version greater than 0.5.16. Pragmas are common instructions for compilers about how to treat the source code (e.g., pragma once).
A contract in the sense of Solidity is a collection of code (its functions) and data (its state) that resides at a specific address on the Ethereum blockchain. Learn more about the constructor and memory in the docs.
Step1: Click button to switch to compile page
Step2: Select “ECT20Token” contract
Step3: Enable “Auto compile” and “optimization”
Step4: Click “ABI” to copy the contract abi and save it.
Now, We have to deploy our smart contract on Echain Network Network. For that, we have to connect to web3 world, this can be done my many services like Metamask, Brave, Portis etc. We will be using Metamask. Please follow this tutorial to setup a Metamask Account.
Open Metamask and select Custom RPC from the networks dropdown
Go to setting page
Add a new network
Testnet * RPC URLs * ChainID: 37068 * Symbol: ECT * Block Explorer: https://explorerb.echain.network
Mainnet * RPC URLs * ChainID: 72198 * Symbol: ECT * Block Explorer: https://https://explorer.echain.network
Go ahead and click save
Copy your address from Metamask
Head over to Faucet and request test ECT
Now, let's Deploy the Smart Contract on Echain Network Testnet
Select Injected Web3 in the Environment dropdown and your contract
Accept the Connection Request
Once Metamask is connected to Remix, the ‘Deploy’ transaction would generate another metamask popup that requires transaction confirmation.
Congratulations! You have successfully deployed a ECT20 Contract. Now you can interact with the Smart Contract. Check the deployment status here: https://explorerb.echain.network/
