[Bug] call to getTransaction on a versioned transaction fail

[nazbrok]

Solana introduced versioned transaction

currently Solnet support only LEGACY transaction because the optional parameter maxSupportedTransactionVersion is not set on getBlock and getTransaction

to my understanding we just need to always set this optional parameter to 0 to support both mode.

To Reproduce

Metaplex action house started to use versioned transaction.
Here is a (failed) TX using versioned transaction : X1GTDnoauLQvM7VoZjC492dVY1YRmYCbUDPX7WwyuiWizFyigJfdGJh61Qrkr7hjAqoo8aVWJLWXEeRgqv7JQPp

calling getTransaction for this tx return this json

{"jsonrpc":"2.0","error":{"code":-32015,"message":"Transaction version (0) is not supported by the requesting client. Please try the request again with the following configuration parameter: \"maxSupportedTransactionVersion\": 0"},"id":54}

Added support for versioned transactions. I believe compile message needs a update to write versioned transaction from the client not totally sure so this only covers the reading portion.

indeed this PR only aim to fix the reading portion for the moment.
My knowledge of Solana isn't great so I didn't dive too much into the writing part (yet)

[nazbrok]

Well looks like this PR only fix the call to getTransaction and getBlock and is finally not enough for the reading portion

The transaction format changed so Solnet currently fail to decode the tx because of the table lookup I think.

This PR allows you to get & decode versioned transactions successfully. You will no longer get the client warning that you mentioned above. The response for the TX in your issue was related to requiring permission from the metaplex auction house. Feel free to pull from my fork and test yourself.
Everything is available in typescript in the Solana Javascript SDK. It just needs to be coded in C# and added to solnet. Ill see what needs to be updated to allow versioned txs to be built and sent from solnet

thanks, your implementation is better.

I quickly looked at the typescript implementation, I will try to give a try if I get the time.

Hi @nazbrok have you managed to implement it in C#?

Hi @nazbrok and @BifrostTitan I'm getting this error of this issue in some transactions! I saw that has a commit fixing this eac7430 but seams to be on a on hold PullRequest #428
Did you have some update of this issue? Do you need any help ?

Hello guys ! I don't see any signature for : GetTransaction , that takes maxSupportedTransactionVersion as a parameter.

Did you guys code a new signature for GetTransaction and GetBlock that uses this maxSupportedTransactionVersion parameter ?

Thanks !

Why is it closed? Are you going to merge it? It seems still not fixed.

It already been patched. Compile from source to use the latest version. The nuget package will be updated soon
