Truffle Migration To BSC Testnet Not Working

Hi

Hope youā€™re all well, iā€™m at a stage now where iā€™m trying to migrate this to the BSC Testnet, I have made the following changes in the truffle-config.js file

bscTestnet: {

  provider: () => new HDWalletProvider(mnemonic, `https://speedy-nodes-nyc.moralis.io/bcf0017bb895dcaaa02ec143/bsc/testnet`),

  network_id: 97,       // Ropsten's id

  gas: 5500000,        // Ropsten has a lower block limit than mainnet

  confirmations: 10,    // # of confs to wait between deployments. (default: 0)

  timeoutBlocks: 200,  // # of blocks before a deployment times out  (minimum/default: 50)

  skipDryRun: true     // Skip dry run before migrations? (default: false for public nets )

},

I have used the wallet provider to get an account which I have filled with 1 BNB but when I type truffle migrate or doing the reset all i get back is

Compiling your contractsā€¦

Everything is up to date, there is nothing to compile.

Any advise?

Hi

Ok so in the truffle-config.js I have the following - version: ā€œ^0.8.0ā€ which is uncommented

The reply i get from the terminal is

  • Fetching solc version list from solc-bin. Attempt #1

and thatā€™s it :-/

Hi @Baz

You can use the --reset option to run all your migrations from the beginning

truffle migrate --reset --compile-all --network bscTestnet

Let me know how it will work for you

Hi thanks for the reply i really appreciate it, iā€™ve just tried that and am getting exactly the same issue

@Baz
I think I got it. Please share the full code of truffle-config.js .

Please take a look at and format your code :raised_hands:

/**

 * Use this file to configure your truffle project. It's seeded with some

 * common settings for different networks and features like migrations,

 * compilation and testing. Uncomment the ones you need or modify

 * them to suit your project as necessary.

 *

 * More information about configuration can be found at:

 *

 * trufflesuite.com/docs/advanced/configuration

 *

 * To deploy via Infura you'll need a wallet provider (like @truffle/hdwallet-provider)

 * to sign your transactions before they're sent to a remote public node. Infura accounts

 * are available for free at: infura.io/register.

 *

 * You'll also need a mnemonic - the twelve word phrase the wallet uses to generate

 * public/private key pairs. If you're publishing your code to GitHub make sure you load this

 * phrase from a file you've .gitignored so it doesn't accidentally become public.

That is my truffle-config.js file, thanks for taking the time to look into this

Does it throw you any errors?

Looks like it canā€™t fetch solidity compiler. Try to change code to:

compilers: {

    solc: {},

  },

If it will not help. Try to download it manually:

Follow this tutorial: https://www.trufflesuite.com/docs/truffle/reference/configuration#external-compilers

Have it work correctly when you deployed the contract previously? Or itā€™s a first time?

Hi, it doesnā€™t throw any errors and this is the first time, I honestly thought this would be the easy part lol
