Minted Tokens via Contract not showing in Wallet (findLikelyTokens)

const findLikelyTokens = async (ctx) => {

REQUEST: Rename and extend the mintedWithBridge query or to create another query to cover contracts that mint tokens.

USECASE: Users accumulate tokens and the accumulated tokens are only minted when claimed. Therefore the minting occurs first in the contract and the ft_transfer occurs in a callback.

REASON: Save on the number of calls, transactions, and gas.

we're minting tokens for the user, can you add ft_mint_to to the possible fn names?

const received = 
        select distinct receipt_receiver_account_id as receiver_account_id
        from action_receipt_actions
        where args->'args_json'->>'receiver_id' = $1
            and action_kind = 'FUNCTION_CALL'
            and args->>'args_json' is not null
            and args->>'method_name' in ('ft_transfer', 'ft_transfer_call', 'ft_mint_to')
    ;

@htafolla @luciotato Thanks for the submission, we appreciate it! Can you tell me where ft_mint_to came from as the method name to use? Is this part of an NEP somewhere that I could reference?

Hey Daryl, I've pinged @mikedotexe as he worked on the spec with @luciotato and others. There is not presently a spec for "mint" that I am aware of. It was listed as "future"

Future possibilities
Support for multiple token types
Minting and burning

We have an implementation for it in Cheddar.

@htafolla @luciotato i think it’s best to create draft NEP at least for minting functionality.

[robert-zaremba]

OK, we will create a NEP for NEP-141 extension.

[htafolla]

@mikedotexe @vgrichina Robert has put together the mint extension, this now also need for MetaPool as stNEAR is now showing in the wallet. Can we expedite this? We plan to launch Cheddar soon as well.
