Trong Klaytn, một hợp đồng thông minh được viết bằng Solidity có thể được biên dịch và triển khai thông qua Truffle. Hiện tại, Klaytn hỗ trợ đến Truffle v5.0.26, phiên bản mới nhất vào thời điểm tạo bài viết này. Vui lòng tìm thông tin chi tiết về Truffle trên các trang web bên dưới.
Bạn có thể cài đặt Truffle như sau:
$ sudo npm install -g truffleNếu bạn có EN cục bộ đang chạy, bạn có thể triển khai hợp đồng trực tiếp với khung truffle. Để biết thêm chi tiết, hãy tham khảo này.
Nếu bạn muốn triển khai với nút EN từ xa, bạn nên sử dụng .
truffle-hdwallet-provider-klaytn là một nhà cung cấp ví JavaScript HD được rẽ nhánh từ truffle-hdwallet-provider.
Cài đặt như sau:
$ nvm use 10
$ yarn install truffle-hdwallet-provider-klaytn@1.0.18$ nvm use 12 # for node v12 and higher
$ yarn install truffle-hdwallet-provider-klaytn@1.4.1Thiết lập truffle-config.js như bên dưới.
