松露合约验证在BSC测试网络上不工作

Question

我正试图验证我从truffle部署的合约，并获得"Etherscan不支持id为97的网络测试网";错误。所以我正在使用Bscscan，并在bsc测试网上部署了我的合同。

我该如何解决这个问题?

我truffle-config.js

const HDWalletProvider = require('truffle-hdwallet-provider');
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();
const BSCSCANAPIKEY = fs.readFileSync("apikey").toString().trim();
module.exports = {
networks: {
development: {
host: "127.0.0.1",     // Localhost (default: none)
port: 8545,            // Standard BSC port (default: none)
network_id: "*",       // Any network (default: none)
},
testnet: {
provider: () => new HDWalletProvider(mnemonic, `https://data-seed-prebsc-1-s1.binance.org:8545`),
network_id: 97,
confirmations: 1,
timeoutBlocks: 200,
skipDryRun: true
},
bsc: {
provider: () => new HDWalletProvider(mnemonic, `https://bsc-dataseed1.binance.org`),
network_id: 56,
confirmations: 10,
timeoutBlocks: 200,
skipDryRun: true
},
},
// Set default mocha options here, use special reporters etc.
mocha: {
// timeout: 100000
},
// Configure your compilers
compilers: {
solc: {
version: "0.6.12"
}
},
plugins: [
'truffle-plugin-verify'
],
api_keys: {
bscscan: BSCSCANAPIKEY
},
}

结果:

> truffle run verify MyToken@{address}--network testnet
Etherscan has no support for network testnet with id 97

安装最新版本的truffle-plugin-verify

最新版本为0.5.4。

npm install truffle-plugin-verify@^0.5.4 -D

为什么会这样?在这个文件(https://github.com/rkalis/truffle-plugin-verify/blob/32ab0f698b1e151849ab463357cded664c5cffa3/constants.js)

你可以看到最后两个API_URLs (56 &97)。这是添加到上层版本，而不是您安装的版本。

const API_URLS = {
1: 'https://api.etherscan.io/api',
3: 'https://api-ropsten.etherscan.io/api',
4: 'https://api-rinkeby.etherscan.io/api',
5: 'https://api-goerli.etherscan.io/api',
42: 'https://api-kovan.etherscan.io/api',
56: 'https://api.bscscan.com/api',
97: 'https://api-testnet.bscscan.com/api'
}
