I want to create a web3 provider on a Node.js application with a specific chainID and URL. How can I do it?

    const chains: Chain[] = await this.chainRepository.find({
      relations: ['currencies'],

    const providers = chains.map((chain) => {
      return new Web3(chain.chainRpc);

Go to chainlist.org/chain/{chain-id}
    e.g. chainlist.org/chain/56 for BNB
Copy the first link under RPC Server Address
Get Web3 object as followin

return new Web3(new Web3.providers.HttpProvider(past-copied-url-here));
