FARCAST founder DAN ROMERO stated that when users click the FRAME button, WARPCAST or SUPERCAST will sign on behalf of the users, and FRAME cannot request a signature from the user's $ETH private key. The design of FRAME means that it does not touch Ethereum addresses. FARCAST is trying to link external wallets and use them within its platform. SlowMist Cosmos pointed out that, based on the security model of FARCASTER FRAMES' private keys, FRAME does not touch $ETH private keys or wallet addresses, but instead signs messages using account keys. However, he also mentioned that the implementation of FRAME and how it securely interacts with wallet funds still need further verification and observation.
