A place for talking about the Ethereum Virtual Machine on Farcaster.

How Login in with Farcaster works

- Farcaster relies on a root ECDSA <> FID mapping onchain; this can be stored in any Ethereum wallet

- You use the ECDSA pair to create EdDSA keypairs for each app; this FID <> EdDSA mapping also lives onchain

- Hubs natively understand this

What are the properties of EdDSA keys that make them useful here?

EdDSA keys are my goto for generic signing - here's the rationale from when we designed Farcaster v1.
