字节编码工具化

解码 CBOR 编码数据 在Ethereum合同的字节码结尾.

安装

yarn add @ethereum-sourcify/bytecode-utils

使用量

团结合同

import { decode, AuxdataStyle } from "@ethereum-sourcify/bytecode-utils";

const bytecodeRaw = "0x60806040526004361061003f5760003560e01...7265206c656e677468a2646970667358221220dceca8706b29e917dacf25fceef95acac8d90d765ac926663ce4096195952b6164736f6c634300060b0033"

// For Solidity contracts
decode(bytecodeRaw, AuxdataStyle.SOLIDITY);

结果实例

{
  "ipfs": "QmdD3hpMj6mEFVy9DP4QqjHaoeYbhKsYvApX1YZNfjTVWp",
  "solcVersion": "0.6.11",
  "experimental": true,
  "bzzr0": "...",
  "bzzr1": "..."
}

维珀合同

import { decode, getAuxdataStyle } from "@ethereum-sourcify/bytecode-utils";

const vyperBytecodeRaw = "0x..."; // Your Vyper contract bytecode

// For Vyper contracts
decode(vyperBytecodeRaw, getAuxdataStyle("Vyper", "0.4.1"));

结果实例

{
  "integrity": "...",
  "runtimeSize": 1234,
  "dataSizes": [32, 64, 128],
  "immutableSize": 256,
  "vyperVersion": "0.3.10"
}

Vyper 版本相容性说明

不同的 Vyper 编译器版本使用不同的 auxdata 格式:

• <0.3.4: 无 CBOR auxdata
• 0.3.4: CBOR 地图 {"vyper": [0, 3, 4]} 无长度页脚
• 0.3.5-0.3.9: CBOR 地图 {"vyper": [...]} 加长页脚
• 0.3.10-0.4.0: CBOR 阵列 [runtimeSize, dataSizes, immutableSize, {"vyper": [...]}]
• >=0.4.1: CBOR 阵列 [integrity, runtimeSize, dataSizes, immutableSize, {"vyper": [...]}]
