📃 Provable pToken ERC777 Smart-Contract

The ETH smart-contract for the Provable pToken! This repo also contains and a bytecode generator for easy bytecode creation with custom constructor arguments.

📯 Note: When using the bytecode generator, for the pToken’s permisionlessness requirements, the default operators constructor argument for this ERC777 Token is provided as a single item array containing the zero ETH address by default.

 


 

👉 Usage

After installing dependencies with npm i, run the tool via:

 node ./bytecode-generator.js      --token-name='pToken'      --token-symbol='PTKN'  

Output of the tool:

 ./example.sh 608060405...00000000  
  • There exists an example.sh script in the ./scripts/ directory you can run to see how the tool works.

  • The tool will compile the smart-contract for you whether the artifact exists or not, so as to ensure it is compiled with the constructor arguments requested.

 


 

💂‍♂️ Smart-Contract Tests:

  1. Install dependencies:
❍ npm install 
  1. Start truffle via:
❍ npx truffle develop 
  1. Run the tests via:
❍ truffle_develop> test 

Test output:

   Contract: pToken/ERC777GSN     ✓ Should transfer via relayer (639ms)     ✓ When transferring via relay, it should pay fee in token (489ms)    Contract: pToken/ERC777OptionalAckOnMint     ✓ Should mint to an externally owned account (95ms)     ✓ Should mint to a contract that does not support ERC1820 (165ms)     ✓ Should mint to a contract that supports ERC1820, and call `tokensReceivedHook` (225ms)    Contract: pToken/ERC777WithAdminOperator     ✓ OWNER cannot change the admin operator (57ms)     ✓ Admin operator can change the admin operator address (44ms)     ✓ adminTransfer() should fail if the caller is not the admin operator (38ms)     ✓ adminTransfer() should transfer tokens (65ms)    Contract: pToken     ✓ `redeem()` function should burn tokens & emit correct events (753ms)     ✓ `operatorRedeem()` should burn tokens & emit correct events (727ms)     ✓ `mint()` w/out data should mint tokens & emit correct events (77ms)     ✓ `mint()` w/out data should return true if successful     ✓ `mint()` cannot mint to zero address (60ms)     ✓ 'mint()' only 0xc49b...2754 can mint (40ms)     ✓ `mint()` w/ data should mint tokens & emit correct events (63ms)     ✓ 0xc49b...2754 can change 'pNetwork' (53ms)     ✓ Only 0xc49b...2754 can change 'pNetwork' (64ms)     ✓ pNetwork cannot be the zero address (51ms)    19 passing (10s)  

 


📋 To Do:

  • Test additions to the standard open-zeppelin ERC777 contract.
  • Bytecode generator.
  • Enforce 0x0000...0000 default operator in bytecode generator.

 


📃 可证明pToken ERC777智能合约👉 用法💂‍♂️ 智能合约测试:

📋 待办事项:

  • 存在示例.sh可以运行./scripts/目录中的脚本来查看工具的工作方式。
  • 无论工件是否存在,该工具都将为您编译智能合约,以确保使用请求的构造函数参数进行编译。
  • 安装依赖项:
  • 启动块菌通过:
  • 运行测试通过:
  • 测试添加到标准open zeppelin ERC777合同。
  • 字节码生成器。
  • 在字节码生成器中强制0x0000…0000默认运算符。你知道吗
  • 可证明的pToken的ETH智能合约!这个repo还包含和一个字节码生成器,用于使用自定义构造函数参数轻松创建字节码。

    📯 注意:在使用字节码生成器时,对于pToken的permissionless要求,默认情况下,此ERC777令牌的default operators构造函数参数作为包含零ETH地址的单项数组提供。

     


     

    📋 待办事项:

    用npm i安装依赖项后,通过:

     node ./bytecode-generator.js      --token-name='pToken'      --token-symbol='PTKN'  

    运行工具的输出:

     ./example.sh 608060405...00000000  
    • 存在示例.sh可以运行./scripts/目录中的脚本来查看工具的工作方式。
    • 无论工件是否存在,该工具都将为您编译智能合约,以确保使用请求的构造函数参数进行编译。
