Ledger path support

[stupid-boar]

master branch use only first account (path ignored)

Expected:

  namedAccounts: {
    deployer: {
      default: 0,
      5: "ledger://m/44'/60'/0'/0/0",
    },
  },

this format ledger://m/44'/60'/0'/0/0 will not work, hardhat-deploy need to know the address before calling ledger

Maybe we could do something like ledger://m/44'/60'/0'/0/0:<address> ?

@wighawag I made it work) I change the address to 0x0000...0 on config parsing

if (protocolSplit[0].toLowerCase() === 'ledger') {
    address = '0x0000000000000000000000000000000000000000';
    addressesToProtocol[address.toLowerCase()] = spec;

Then (transport init) I take PATH from protocol string (this is true, because hardware level)

ethersSigner = ledgerSignerFactory(
  provider,
  registeredProtocol.substr(9)
);

We have successfully deployed smart contract

The issue is that namedAccounts are also used to references address, if you set it to zero address for all ledger then you cannot use that functionality

I'll fix it soon ledger://m/44'/60'/0'/0/0:<address>

[stupid-boar]

@wighawag fixed)

[wighawag]

Nice! should have mentioned before, but we need to provide backward compatibility for those we put ledger://<address> in this case, the default path should be taken like before

[stupid-boar]

I'll fix it soon

@wighawag done)

@wighawag it's done)

@wighawag i fixed concurrent access to ledger device by using singleton pattern. Now it's work!)
