Set default accounts for truffle like hardhat

Question

I'm using the truffle suite against a custom network. This network returns an empty list in response to eth_accounts. So I need to feed the truffle with default accounts (I mean default private keys) in the configuration file just like hardhat. Is it possible in truffle?

I also set from in networks in truffle-config.js but after that truffle sends an eth_sendTransaction instead of eth_sendRawTransaction and again my custom network doesn't support eth_sendTransacton

You have to configure truffle to use @truffle/hdwallet-provider.

const HDWalletProvider = require("@truffle/hdwallet-provider");

const mnemonicPhrase = "..."; // Use the wallet mnemonic phrase

module.exports = {
  networks: {
    mynetwork: {
      provider: () =>
        new HDWalletProvider({
          mnemonic: {
            phrase: mnemonicPhrase
          },
          providerOrUrl: "https://ropsten.infura.io/v3/YOUR-PROJECT-ID",
        }),
    }
  }
};
