I'm attempting to clone some contracts that are available on mainnet and deploy them to Ghostnet. When trying to deploy the Hic et Nunc Marketplace (https://tzstats.com/KT1HbQepzV1nVGg8QVznG7z4RcHseD5kwqBn), I've been running into the following issue:

failed to deploy contract: tezos: kind=permanent, id=proto.017-PtNairob.michelson_v1.deprecated_instruction, reason=

What's causing the issue?

This script uses the SUB instruction on type mutez. This variant of the SUB instruction has been deprecated in Ithaca and the SUB_MUTEZ instruction should now be used instead.

  • Thank you. After amending the contract code to use the SUB_MUTEZ instruction instead of the deprecated SUB variant, I'm now facing the following error: id=proto.017-PtNairob.michelson_v1.undefined_binop Sep 19, 2023 at 11:41
  • Please open another question and give the original and modified Michelson scripts. Sep 22, 2023 at 7:12
