Open source zero-fee trustless Bitcoin NFT marketplace
OpenOrdex is an open source zero-fee trustless Bitcoin NFT marketplace based on partially signed bitcoin transactions

The seller creates a partially signed bitcoin transaction (PSBT) specifying the price of the ordinal.
The buyer can then sign the PSBT and broadcast it to the network.
