• (Reccomended) deployment with auto-deploy configuration for an NFT auction contract, verify etherscan and write addresses to the addresses.json.
  • auto-deploy sets gas info automatically. Deployment without auto-deploy requires to configure gas info manually.

yarn task:deploy-and-configure --network [network] --auto-deploy

# ex.) for goerli
yarn task:deploy-and-configure --network goerli --auto-deploy

• deployment with manual configuration for an NFT auction contract, verify etherscan and write addresses to the addresses.json.

yarn task:deploy-and-configure --network [network]

# ex.) for goerli
yarn task:deploy-and-configure --network goerli

Use Remix to deploy.

In case you only want to verify a contract for block explorer.

yarn task:verify --contract [path:contractName] [contractAddress] --network [network]

# ex.) contract on goerli
yarn task:verify --contract contracts/proxies/AuctionProxy.sol:AuctionProxy 0xF99a8b2DF498bc3ea2044f1943C210A4fd946b2E --network goerli

This smart contract follows various gas optimization methods. Some of the methods can be found here.
