solidity - RSK Bridge 智能合约的 Solidity 接口是什么？

Question

RSK 桥通过部署在0x1000006. 我能够在 github 上找到Bridge 的 ABI 文件。

我正在寻找一个 Solidity 接口文件 - 有没有可用的，如果有，我在哪里可以找到它？

Answer 1

由于您有 ABI，请将其放入名为“bridge.json”的文件中。将下面的脚本复制到同一文件夹中的文件中，然后在终端命令行中启动它，如下所示：'node filename.js'。然后在同一文件夹中的“Bridge.sol”文件中找到您的 Solidity 桥接接口。您需要在系统中安装 node.js 才能运行此脚本。

const fs = require('fs')
/** Name of the bridge ABI file */
const bridgeABI = require('./bridge.json')
/** Filename for the generated Solidity bridge interface file */
const BRIDGE_SOL = 'Bridge.sol'
​
const functions = bridgeABI.filter((element) => element.type === 'function')
const stream = fs.createWriteStream(BRIDGE_SOL)
stream.write(`// SPDX-License-Identifier: GPL-3.0
pragma solidity >=0.7.0 <0.9.0;
​
interface Bridge {
`)
functions.forEach((f) => {
  // function parameters
  const inputs = f.inputs
    .map((i) => {
      // add 'calldata' to the following types
      const type = ['bytes', 'bytes[]', 'bytes32[]', 'string'].includes(i.type)
        ? `${i.type} calldata`
        : i.type
      return `${type} _${i.name}`
    })
    .join(', ')
  // function return values
  const outputs = f.outputs
    .map((o) => {
      // add 'memory' to the following types
      const type = ['bytes', 'string'].includes(o.type)
        ? `${o.type} memory`
        : o.type
      return `${type}${o.name ? ` ${o.name}` : ''}`
    })
    .join(', ')
  // record a single function signature
  stream.write(
    `    ${f.type} ${f.name}(${inputs}) external${f.constant ? ' view' : ''}${
      outputs ? ` returns (${outputs})` : ''
    };\n`,
  )
})
stream.write('}\n')
stream.end()
console.log(`The bridge was generated. Find it in the file ${BRIDGE_SOL}`)

这是由上面的脚本生成的界面：
