Smart contract learning materials

explain

The work of smart contract is mainly divided into 5 A module （ See the secondary directory on the right ）, Of course, the precondition for everything is business orientation .

Because the contract has certain limitations （ E.g. handling charges , On line can not be modified ） Generally, it is necessary to understand the existing business system first , Integrate other tool library code , Just like splicing building blocks to build a set of systems you need , You need to have a certain understanding of the mainstream contracts in the market .

Existing deficiencies

Current contract risk control , Monitor the notification system

Running environment ：

This paper mainly uses eth Of evm Compile for unique 、 Running environment （ apply eth、bsc、heco、matic etc. ）. Language use solidity.（tron and vision Have their own small changes , Available but needs debugging ）

If it is another chain such as solana,polkadot,ckb etc. , You may need to learn something else .

Such as solana Only use rust Write a contract （rust Learning , Address ：Rust Introduction to programming language （Rust Language /Rustlang）【 It's over 】_ Bili, Bili _bilibili）;

3、 Contract interaction

You need to understand the relevant concepts of blockchain , Be familiar with the classification and simple application of tools ,geth、remix、etherscan、web3（ or ethers）、Truffle（ or hardhat）、Ganache( or Ganache CLI) etc.

Compile and deploy ：Truffle

Local debugging ：remix,Ganache,console.log

unit testing （ lack ）

Provide sdk or api （ lack ）

4、 Contract security （ Audit + unit testing + Code scanning ）
