Facing error on deploying contract in Binance Smart Chain - blockchain

Question

I am trying to deploy a test contract on Binance Smart Chain network. I am using metamask, and truffle to create and test the contract. My folder structure looks like this
const HDWalletProvider = require('truffle-hdwallet-provider-privkey');
const privateKeys = process.env.PRIVATE_KEYS || ""
module.exports = {
networks: {
development: {
host: "127.0.0.1",
port: 7545,
network_id: "*"
},
binancetestnet: {
provider: function() {
return new HDWalletProvider(
privateKeys.split(','), // Array of account private keys
`https://data-seed-prebsc-1-s1.binance.org:8545/${process.env.INFURA_API_KEY}`// Url to an Ethereum Node
)
},
gas: 5000000,
gasPrice: 25000000000,
network_id: 97
}
},
// Set default mocha options here, use special reporters etc.
mocha: {
// timeout: 100000
},
// Configure your compilers
compilers: {
solc: {
version: "0.7.3", // Fetch exact version from solc-bin (default: truffle's version)
// docker: true, // Use "0.5.1" you've installed locally with docker (default: false)
// settings: { // See the solidity docs for advice about optimization and evmVersion
// optimizer: {
// enabled: false,
// runs: 200
// },
// evmVersion: "byzantium"
// }
}
}
};

I have attached all the code with errors I am facing. Can anyone help me with it?
I have also Installed the HD Wallet provider as well. Truffle compile worked successfully.

Answer 2

I faced similar problem, and found the solution to use private key instead of mnemonic:
in your .env :
API_URL = "https://ropsten.infura.io/v3/your project id" # note: put your node url here
PRIVATE_KEY = "your account private key"
and in your truffle-config.js:
module.exports= {
....
rospten: {
provider: () => new HDWalletProvider(
process.env.PRIVATE_KEY,
process.env.API_URL),
network_id: 3,
gas: 1000000,
gasPrice: 20000000000,
confirmations: 2,
timeoutBlocks: 200000,
}
....
}
