A place for talking about the Ethereum Virtual Machine on Farcaster.

What are the best ways to keep (offchain) profile/metadata in sync with a smart contract? Like a tokenuri with metadata.json on IPFS..

The data could get updated frequently tho and I'd like to avoid updating the hash every time. Any suggestions?

I just store the block number since my last cache and replay the log events since then to catch up. I even do that on the client side, since it's one query and pretty quick if cache is recent enough.

Ah thought you meant you need to track onchain updates for offchain stuff, not the other way around.

Not sure I understand. You store the block nr client side to fetch latest log updates? But that still means you're relying on onchain actions, right?

I'm building a project registry, where it's mainly the project Id that is important on chain. Owners should be able to edit, post updates/milestones, etc. (offchain)
