Bitcoin/NOTE Actions is a standardized interaction process. It allows for token transfers and PSBT transaction signing on the Bitcoin blockchain without the need for third-party services like Wallet Connect or wallet-embedded browsers for web script injection.
The thing is, you could already sign PSBT transactions without any special software or protocols.
By integrating with the [Open Graph protocol](
https://ogp.me), it enables transaction previews on social media platforms like X, Discord, and Telegram. It is also compatible with the BIP21 Bitcoin payment protocol.
This is something that I think would be pretty cool. It would be like how you can just post an email address to send someone a PayPal payment. Although we would have some work to do if we want to make a Bitcoin payment URI that concise (without the amount) AND preserve privacy by utilizing a different address each time.
Maybe we don't see eye-to-eye on this but I think this would be nice to make requesting for payments better, instead of just more dApps.
