This template contains everything you need to deploy a basic Open Zeppelin ERC20 contract to the Telos EVM Testnet Network. Follow the steps below to deploy and interact with your own ERC20 token in minutes !
This template requires NodeJS & NPM installed on your machine and a wallet address on the Telos EVM Testnet Network.
Commands used below work on recent Linux or Windows versions but have not been verified for Mac
- Click the "use this template" button in this repository and copy the URL you are redirected to once the generation is finished.
- Change the following configuration values in the
.envfile of your newly created repository:ACCOUNT: MY_TESTNET_EVM_ADDRESSTOKEN_NAME: My TokenTOKEN_SYMBOL: MYTOKTOKEN_INITIAL_SUPPLY: 10000
- Install the repository on your machine with
git clone [PREVIOUSLY COPIED URL](GIT required) or download the code and install it manually - Enter the directory of the project on your machine and install its dependencies by running
npm install
- Use
npx hardhat testto build and launch the tests
- Build & deploy using
npx hardhat --network testnet deploy - Save the contract address returned in the console, ie:
0xe7209d65c5BB05Ddf799b20fF0EC09E691FC3f11, you will need it for the next steps ! - Interact with your contract using the hardhat console, our block explorer, wallets like metamask or by deploying our example wallet repo
- Verify your new token contract with
npx hardhat --network testnet sourcify - You may run into a "gateway timeout" error message, do not worry, the contract will still be verified
- Make sure your contract is verified by running the command again, you should get this message back:
already verified: MyContract (0x2A3b40A59109a84ab82a0Ff1A3910bb595082e09), skipping.
"<html>\r\n<head><title>504 Gateway Time-out</title></head>\r\n<body bgcolor=\"white\">\r\n<center><h1>504 Gateway Time-out</h1></center>\r\n<hr><center>nginx/1.14.2</center>\r\n</body>\r\n</html>\r\n"
The sourcify server connection timed out but your contract is still getting verified, run the npx hardhat --network testnet sourcify command again to make sure, it should tell you it is already verified !
