Farcaster Devs

Sign in with Farcaster conundrum

1. Currently requires ECDSA key (custody address) signature, which for most users is only on their mobile device with Warpcast app

2. Changing to EdDSA key (signers) would mean any Farcaster app could sign on your behalf -- making it easy for users to SIWF entirely on web -- but also makes the weakest link signer able to impersonate you on any app that has SIWF (note: just using SIWF and not requiring a signer)

3. Changing to a tiered system for EdDSA keys (super write keys vs. basic write keys) requires a bunch of work, adds complexity, requires contract audit, etc.

4. If no change, for most people they will always have to have their phone (which is how WhatsApp works, fwiw).

5. Current approach is grind out the last 10-15% of edge cases on QR code scan / mobile deeplink reliability.

Curious what others think.

I like how it's done on Lens, the NFT profile and the ability to connect via a signature from the wallet.
