@EoinMcQuinn What wallets normally allow you to do, that is receive and send transactions.

Presumably HWI on github.com is to do with creating a hardware wallet interface with Bitcoin Core. Am I correct?

What stage is development at presently?

Will one be able to connect a hardware wallet to Bitcoin Core with this interface?

Yes, you can connect an external signer to Bitcoin Core. You can either use HWI (Hardware Wallet Interface), which is developed by Bitcoin Core developers but currently considered experimental, or use a compatible script if one is provided by your hardware wallet vendor.

To use the external signer feature, start bitcoind with the parameter:

```
$ bitcoind -signer=<path/to/hwi.py>

```

Or if you use the Bitcoin Core GUI, you can fill in the "External signer script path" field in the "Wallet" tab.
