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

How does FID creation work now that it’s all mainnet?

Will that get exposed to the hub APIs once it’s fully open?

It's still gated right now, but you register a FID for free (just gas). You need to pay for a storage slot with the storage contract. It's done as a single transaction during sign up.
