Development guide

This section helps developers to quickly write, deploy and debug contracts on the Alaya network and develop various DApp applications based on the contracts.

What is DApp?#

A DApp is a decentralized application built on the blockchain. It usually consists of a series of contracts, an interactive front-end and a back-end service.

What a DApp?#

A DApp is a decentralized application build on the blockchain, usually consisting of a series of smart contracts, an interactive interface, and backend services.

Set up local development environment#

  • Private network - Build a private node or cluster network locally, which can help you debug your local application quickly.
  • Join the dev network - Use the development network to test your application in a more open network environment.

How to Write Contracts?#

Tools for development#

  • Alaya-Truffle - A contract development framework that supports WASM and Solidity contracts.
  • IDE - An interface-based development tool that supports WASM and Solidity contracts.

Solidity contract#

  • Getting started - An example of how to deploy, compile, publish, and call contracts on the Alaya network.
  • Best practices - Learn about some of the specifications for writing contracts on trasaction fees.
  • Development costs - Introduces the fee cost about Solidity contract deployment and call, and the comparative analysis of the fee with Ethereum.
  • Contract security - A few writing specifications on how to improve the security of the contract.
  • Migration tutorial - A tutorial on migrating Solidity contracts from Ethereum to the Alaya network.

WASM contract#

WASM currently supports contract development in C++ language, that would be welcome if you want to extend WASM to support contracts in other major languages.

  • Getting started - An example of how to deploy, compile, publish and invoke a WASM contract on the Alaya network.
  • Development costs - Introduction to the fee cost about WASM contract deployment and call.
  • Best practices - Learn about some of the specifications for writing contracts on trasaction fees.
  • Wasm_API - Introduction to WASM's contract library.

Front-end or back-end development#

You can interact directly with the contract through the front-end directly, and the following documentation will help.

  • Samurai API - Introduction to a Web Wallet API that supports the Alaya network.
  • JS SDK - How to use JavaScrip to interact with contracts on the Alaya network.

If you want to interact with the Alaya network by writing back-end services, the following SDKs in different languages can help.

PRC Token#

Since Alaya inherits EVM, the Alaya network is theoretically compatible with all standard Token protocols on Ethereum. Token protocols that are currently explicitly supported are ARC-20和ARC-721.
