user100290: Let's say I am spending from a 2-of-2 multisig with this script:

OP_2 <len(pubkey1)> <pubkey1> <len(pubkey2)> <pubkey2> OP_2 OP_CHECKMULTISIG

What would go in the scriptCode according to BIP143? Is it just the script listed above? Here is the relevant part from BIP143.

For P2WSH witness program,
  - if the witnessScript does not contain any OP_CODESEPARATOR, the scriptCode is the witnessScript serialized as scripts inside CTxOut.
  - if the witnessScript contains any OP_CODESEPARATOR, the scriptCode is the witnessScript but removing everything up to and including the last executed OP_CODESEPARATOR before the signature checking opcode being executed, serialized as scripts inside CTxOut. (The exact semantics is demonstrated in the examples below)


user48884: Yes, the scriptCode would be that multisig script.
