The buyer creates a PSBT, filling in the transaction information (such as input address, output address, amount, etc.) in the PSBT.\n2. The buyer signs the PSBT but intentionally leaves part of the signature (such as hash prefix).\n3. The seller receives the PSBT and completes the remaining signature (such as hash suffix).\n4.
