DegenRocket added support for Nostr private keys via browser extensions like nos2x and Flamingo, becoming the first social media platform to simultaneously support different protocols (Nostr and DMP) and different private keys (Nostr and Ethereum) in accordance with the Signer and Protocol Agnostic Social Media (SPASM) specification.

Since the 'nostr-tools' npm library doesn't allow signing of arbitrary messages, extra values were added as tags to make Nostr events compatible with the DMP protocol such as the MIT license, spasm_version, spasm_target, and spasm_action.

The new Nostr functionality can be tested at two instances:
