How would one go about adding starknet wallets to Farcaster?

Currently connected wallets are broadcast onhub with a Address Verification message: https://docs.farcaster.xyz/developers/guides/writing/verify-address There's a way to do this for Solana, but it doesn't look like the docs are updated...so perhaps there's an easy way to extend it to Starknet Personally, I would just add another address entry to your ENS profile. Explorers like Zapper could figure it out from there, but not everyone is using an ENS.

Other than the docs do you know if there’s something else written on the process of adding Solana?

@v
you can look at the protocol spec for verifications. i'm not terribly familiar with starknet but if they are ECDSA addresses it should be trivial

Thanks! Digging in. No, Starknet uses the Stark-friendly curve (Secp256k1 alternative) and signatures are Pedersen hash-based. I'd to deploy a custom StarkNet contract that performs the necessary conversion. Or use off-chain cryptographic libraries to emulate ECDSA signatures from a StarkNet private key. Then deploy a smart contract on Ethereum that accepts StarkNet signatures and performs necessary translation and relay operations to Farcaster.
