The transaction version number must be set to at least 2. <ref>'''Why does the transaction version number need to be at least 2?''' The transaction version number is part of the validation rules for some features such as OP_CHECKSEQUENCEVERIFY. Since it is backwards compatible, and there are other ways to disable those features (e.g. through sequence numbers), it is easier to require transactions be able to support these features than to try to negotiate the transaction version number.</ref> -The Creator should also set PSBT_GLOBAL_PREFERRED_LOCKTIME. +The Creator should also set PSBT_GLOBAL_FALLBACK_LOCKTIME.
