Conversation

@thesimplekid Should we make it clear that wallets should use an ephemeral (one time) key? |

| "19": { | ||
| "supported": <bool>, | ||
| "required": <bool> | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| In addition to signaling optional support, the mint can require a public key for mint quotes and a corresponding signature during minting. If `required` is set to `true` in the NUT-19 settings: | ||
|
|
||
| 1. The wallet **MUST** provide a public key when requesting a mint quote | ||
| 2. The wallet **MUST** provide a valid witness signature when submitting the mint request | ||
|
|
||
| > **Note:** Enabling this setting makes the mint incompatible with wallets that do not support NUT-19 | ||

I wonder if the required flag should be set by specific NUT. For BOLT12 and Onchain NUTs it will be a MUST as it is already specified in the PRs for those but I don't think this should break wallets that don't implement it for NUT-04.

I think we can remove the required flag here. Leaving it up to wallets to choose to use it or not for NUT04 and future nuts that want to require it (eg bolt12) can specify that there.

Is this error still necessary?

For future reference: https://json-schema.org/understanding-json-schema/reference/object#required
This NUT defines a protocol extension that enables signature-based authentication for mint quote redemption. When requesting a mint quote, clients can provide a public key. The mint will then require a valid signature from the corresponding secret key before processing the mint.
This is defined as an optional extension to NUT-04 and the intention is to reuse it and make it mandatory for bolt12 and onchain.
