@buffalojoec, can you review the sample TransferFeeExtension schema?

[buffalojoec]

Here's what initializeTransferFeeConfig looks like on the RPC if you just create a token using the CLI on the local validator and then query the transaction.

As you can see, the transaction-status, and therefore the jsonParsed module of the RPC, just treats Token-2022 extension instructions as any old Token-2022 instruction.

Let's do exactly that with GraphQL! Here's an example of what I mean:

type SplToken2022InitializeTransferFeeConfigInstruction implements TransactionInstrucion {
  programId: Address
  maximumFee: BigInt
  mint: Account
  transferFeeConfigAuthority: Account
  withdrawWithheldAuthority: Account
}

What do you think?

[buffalojoec]

TransferFeeExtension actually has its own set of instructions, as each extension does. I think you've globbed together all of them here:

• TransferCheckedWithFee
• WithdrawWithheldTokensFromMint
• WithdrawWithheldTokensFromAccounts
• HarvestWithheldTokensToMint
• SetTransferFee

[buffalojoec]

As I mentioned in my comment here, all Token-2022 extensions actually have their own set of instructions (sometimes just one), and we can just treat each of those instructions as individual Token-2022 instructions!

[buffalojoec]

@Hrushi20 Thanks for taking on this effort. I'm pumped we're going to be adding support for Token-2022 extensions!

I have a few suggestions, if you don't mind.

For starters, maybe let's use the issue to track the overall effort, and then just do one PR per extension, where you add the extension to the schema and add a test? They'll all be super small but it will be easier to track as we go. I can update the issue with a list of all instructions if that's easier?

To start the process off, it might be a huge help to create a token on the CLI that has every single extension possible, and just copy-paste that transaction into the __setup__.ts test module to use for all your tests!

[buffalojoec]

@Hrushi20 I've updated the issue with the big list of all extensions. #2406 (comment)

And I've also added a PR with a mock transaction! #2544

[Hrushi20]

Hey! Thanks a lot for explaining and helping me out. I'll start of by creating a token having all extensions and adding it to __setup.js. Then we add incrementally add schema and test them separately in different PR's.

I did this already! I linked a PR in my previous comment where I laid this up. If you follow the Graphite stack I also did a couple extensions with tests, as reference.

I missed that comment. Too late here in my country. Will work on this tmr. Thanks :)

[buffalojoec]

I think we can close this, since we've rallied around the issue and you've got a few other PR's in flight!
