Got a question about signatures. If you’re looking to connect a wallet to an account with a signature, what would you use to prevent replay attacks? 

Farcaster uses the blockHash.
OpenSea uses a random cryptographic nonce. 
Transactions use the nonce of the address.

Which is right for linking accounts?

For anything more than a weekend project I’d probs use the SIWE standard https://login.xyz/

It uses a nonce with an optional expiration timestamp

There should be many open source examples of it

Ty! What about if you have a mobile app and a website and you might have a changing domain/bundle identifier that is hard to verify?
