• Solhint: linter
• Solcover code coverage
• Prettier Plugin Solidity: code formatter

Question

node.js v18 for windows

"deploy": "SET NODE_OPTIONS=--openssl-legacy-provider && yarn build && hardhat run scripts/deploy.js",
"deploy:registry": "SET NODE_OPTIONS=--openssl-legacy-provider && yarn build && hardhat run scripts/deploy-registry.js"

node.js v18 for Linux

"deploy": "export NODE_OPTIONS=--openssl-legacy-provider && yarn build && hardhat run scripts/deploy.js",
"deploy:registry": "export NODE_OPTIONS=--openssl-legacy-provider && yarn build && hardhat run scripts/deploy-registry.js"

npx hardhat verify

#npx hardhat verify --contract contracts/ERC20Token.sol:ERC20Token --network goerli 0xxxx021221212 \"USD Coin\" \"USDC\""

• CMD: npx hardhat verify
• contract: --contract contracts/ERC20Token.sol:ERC20Token
• contract address and parameters: --network goerli 0xxxx021221212 "USD Coin" "USDC""

　The parameters must be the same as those published in the contract
