Ethereum

is there an onchain protocol that lets you verify ownership of multiple addresses similar to farcaster verifications?

you can do this on icebreaker by linking multiple wallets

CEO at Google • co-founder & rectangle mover at /icebreaker • icbk.me/j4ck.fc • /j4ck • /swagcaster • DJ sixsix

profiles are not onchain

but you can equip these linked wallets to a profile and get them via the free and open API

gotcha

so the user needs to be on icebreaker and verify their wallets before it can be queried? is there an API endpoint to update it on behalf of a user if i could get the signature from them?
