The Bitcoin Action Protocol Draft

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. 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.

Before the appearance of the NOTE protocol (https://noteprotocol.org), Bitcoin dApps were very rare and mostly limited to simple payment protocols like BIP21. From now on, with the introduction of smart contracts, there will be a significant increase in the number of dApps. The powerful Action protocol enables peer-to-peer payments between wallets and dApps, while also greatly enhancing the user experience by leveraging social media traffic.
