I am trying to build a token that I could airdrop to an account, and not be able to be transferred between accounts.
I had two ideas:TOKEN_2022 Unfreeze Account -> Mint -> Freeze AccountTOKEN_2022 Non Transferable Mint with Metadata
Now when trying to create a Mint account TOKEN_2022_Program in the same instruction with the Non Transferable Mint and createCreateMetadataAccountV3Instruction I get the following error:
'Program metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s invoke [1]'
'Program log: Instruction not supported for ProgrammableNonFungible assets'
This is the code for it:
