According to BlockBeats, on February 23, the Bitcoin NFT market OpenOrdex has launched its mainnet and testnet. Sellers can create a partially signed Bitcoin transaction (PSBT) to specify the price of the serial number, and then the seller can sign the PSBT and broadcast it to the network. Currently, OpenOrdex is compatible with the Taproot wallet, and the command line interface (bitcoin-cli) of the Bitcoin client can be used for buying and selling. The Bitcoin wallet Sparrow can currently only be used for purchases. OpenOrdex is an open source zero-fee trustless Bitcoin NFT market based on partially signed Bitcoin transactions, launched by Fireblocks blockchain engineer Oren Yomtov.
