The NIP defines the interoperability of Bitcoin Tokens, such as BRC20 tokens, among different DEXs (Decentralized Exchanges). DEXs utilizing this protocol enable the circulation of user order data among other DEXs using the same protocol, allowing for public display and cross-platform transactions. This enhances trading efficiency by increasing the exposure of user orders. The protocol was authored by the Orders.Exchange team.
