I don't know a frame is and by this point I am too afraid to ask.

Onboarding, onchain privacy with accountability, crypto law, and emergent use-cases in Ethereum. Currently on a break.

Thank you very much for the response.

Do frames have any other functions?

Basically, Frames are NFTs you acquire by simply pressing the “Mint” (or equivalent) button on the screen of the Warpast app (or alternative Farcaster client). You don’t even need Warps for this; that 1 click sends the Frame straight to the Ethereum address linked to your Farcaster account.
