I need a view function that checks if a user owns a Paras NFT without scanning all tokens. For example:
near view paras-collectible.testnet get_owner_info '{"user_key": "USER123"}'
Is there a direct method?
hey, i guess paras doesnt have a builtin direct view func yet. u might need to use offchain indexing or check the contract code for internal mappings. hope that clears things up a bit, cheers
In working on verifying NFT ownership on Paras, I found that direct querying of on-chain state for ownership information tends to be inefficient due to the lack of a dedicated view function. An approach that worked well for me involved leveraging offchain indexing to capture state changes through event logs, which then allowed quicker lookups. This method introduces some complexities in terms of keeping data synchronized, but it offers a workable compromise until more optimized on-chain methods or improved native support becomes available.
hey, i’ve been poking around this nft ownership verify thing too and honestly it’s a bit of a wild ride. i was trying out a few view functions and ended up wondering if there’s maybe a shorter or more direct path to check ownership without dusting through every token. for me, i think the key might be working with some kind of built-in mapping or index in the smart contract that tracks user holdings, but i’m not 100% on how paras has implemented that lately. has anyone seen recent updates or experiments on using a more targeted query? also, i’m a bit curious how performance scales as collections grow - has anyone tested the response time when using these kinds of direct lookups? i’d love to hear more about others’ experiences or if there are alternative ways to optimize this process. cheers!
hey folks, i’ve been mulling over this query and was wondering if someone ever looked into a custom workaround. like, if paras’ native functions dont directly support checking user ownership without looping through tokens, maybe try setting up a tiny proxy contract that updates an indexed map on every transfer? i mean, i get that its a bit of extra overhead and could potentially add some gas usage, but it might offer a clean view function to just point at a user and say what nfts they own. anyone else juggled this option or perhaps found another creative hack? also, what do you guys think about using a hybrid approach with some offchain caching to keep the data fresh without scanning the whole collection every time? would love some feedback and any new ideas as paras and nft contracts keep evolving, cheers!
