[Suggestion] Add exotic Cells support in wallets

[yungwine]

I think its important for wallets to support exotic Cells sending. Nowadays we have a lot of special cells implementation in SDKs for popular languages, so its not really a problem to implement that in wallets. However as I checked Tonkeeper and Tonhub do not support that, so I think we can open a bunch of footsteps for this. @delovoyhomie @Gusarich wdyt?

The issue lies more with their SDKs than with the wallets.

@thekiba, @tvorogme, @ProgramCrafter, @howardpen9, how do you view the idea of integrating exotic Cells into wallets? Undoubtedly, it's an intriguing feature, but will it be truly beneficial? Could you share your experience and instances when you felt a need for such an integration?

Wallets, as well as their representatives, @divana, @xtonwallet, @tonflow, @sorokin0andrey, @mytonwalletorg, @tonsafe, @dvlkv, @KuznetsovNikita, are you ready to implement wallet support with Exotic Cells.

Do you mean preview tx or what? SDK prepares tx and wallets just send its to the blockchain. An exotic cell prepares not into wallets. The wallet just can show what type of tx will be sent, but only of it knows abi/tl-b for such tx type. Please clarify more what we have to do...

[ProgramCrafter]

@delovoyhomie it's needed for sending Merkle proofs and updates cells - required, for instance, for Compressed NFTs standard.

@xtonwallet The wallet applications should be able to correctly parse BOCs with exotic cells, wrap them into signed transactions and send them. The task is in place since wallets often use some underlying SDK which may not have support for exotic cells.

[xtonwallet]

Does any place exist where we can collect all BOCs for the parsing and displaying for the end user? For example as here - https://github.com/tonindexer/anton/blob/main/abi/known/tep74_jetton.json

We're not talking about some exact messages or structures here. It's about correctly handling exotic cells in general. As far as I know, at the moment, when you try sending a message containing exotic cells in its body - it fails to parse it and so user can't confirm the transaction.

@delovoyhomie

but will it be truly beneficial?

100% we need this. It'll be cool to have this with v5 wallet release, so plugins can use exotics. Currently, you can sign raw cell, but it's not very user-friendly and simple.

Hey, @xtonwallet! As I know Xtonwallet uses tonweb, but tonweb doesn't support exotic cells. So the Xtonwallet source code needs to be updated to use ton-core package instead.

agreed, but need to create some repository or another place with all BOCs that wallets will be able to parse and show in the user-friendly format. And if some new standard will be appeared, then BOC with a structure will be added and all wallets will support this new format intuitively.

yes, correctly, we are working already on a big update that will fix and this issue.

@xtonwallet there are no new "standards" in BoC format. We just need to make sure wallets work correctly with exotic cells.

@xtonwallet It seems you're missing the point. The feature you're talking about is "attempt to understand what dApp is sending and display that". The feature I'm talking about is "dApp tries to send something with exotic cell, wallet should be able to at least do this even if it can't understand the message structure".

Let's more clarify then. TC2.0 demands that dApp must to prepare tx BOC itself, in this case a wallet just must to send it without any modification and it doesn't rely on any SDK in the wallet. If so, we have only the issue with the displaying of that dApp wants to send to the blockchain behalf of the user. Or, if some moment is missed again, please, provide some test BOC with the exotic cell that we can use to check a behavior among the wallet apps.

@xtonwallet This is an error, since dApp prepares an internal message, and wallet app still has to sign it and pack in an external message to wallet contract. dApp simply can't do that because it doesn't have access to private key.

ok, confirmed, some missed info was from our side. For our wallet needs to migrate on ton-core and it will resolve the issue for deserializeBoc on this step.

Do we have some service that uses exotic cells already? We want to test our solution on the real case.

no such services were created because no wallets supported exotic cells up to this point.
but you can just try sending any message with exotic cell in it. @yungwine can help with checking if it works, I think

[yungwine]

@xtonwallet you can follow this link to send message with exotic cell:

ton://transfer/<address>?amount=10000000&bin=te6ccgEBCAEAqgABAAEJRgNE79D9__qPFSM5oBkd4eHFkB_c_hN5ivRDZAr5lha5dwADAiIGAAB4AwQoSAEB7HwTeWGHA1koBNOjP34SDOvpRvp4pndfbuLijYDdt9wAAiEEAAsFIgGIBgcAQ4AN63jPMNwMhhLDs74AhnJNSZslyy-7sVTAhsi1hBei8FAoSAEBpFi4wNxRapsTfZm3Abtg_iX0H1rP8qVKLKSTZoiIDmQAAA==

Success is 1 by tx that was specified above - https://explorer.toncoin.org/transaction?account=EQAJq2VB-_ivbfnpQfzBk0qT2Tuo8CCYWqJTaHSh_CQuNnC3&lt=42692293000005&hash=31DD911D6B628E82A3C8A130D6CE923D84C659585FFB95732F65149739A1C8DE
