Fireblocks blockchain engineer Oren Yomtov posted on Twitter that the Bitcoin NFT market OpenOrdex has launched the 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, the command line interface of the Bitcoin client (bitcoin-cli) can be used for buying and selling, and the Bitcoin wallet Sparrow can only be used for purchases.

It is reported that OpenOrdex is an open source zero-fee trustless Bitcoin NFT market based on partially signed Bitcoin transactions, launched by Fireblocks blockchain engineer Oren Yomtov.
