wow got answered in 1min already

2nd question: is there an easy and efficient (cheap) way to get either (i) all fids' connected addresses easily or (ii) changes in connected addresses?

thinking about how to authenticate `msg.sender` on-chain as someone that controls a given `_fid`:
1. query dune for all (fid, verified address) pairs (updated via neynar)
2. generate merkle tree over all w/ keccak256(fid, address)
3. host API and/or publish this somewhere for free

am I missing something

neynar is actually writing this to Base already:

not sure how often it updates, but I checked my warpcast wallet yesterday/just now, and it didn't show up >:(

if this was updated, does it serve your use case/purpose?

if I assume that it stays updated forever, yeah :D

said this in another reply, but for my specific usecase, it seems hard to maintain the registry as # of fids grows vs updating a merkle root
