Farcaster-solidity 0.1.2 is released 🎉 

- Added Frame Actions support, so you can attest to Frames actions onchain

In layman's terms - each Frame click comes with a signature, which proves that the user indeed clicked the button. Now you can verify this click onchain, creating trustless onchain frames!

Not even close, but still expensive :) Blake3 hashing is 500k-1m gas, and Ed25519 signature verification is also 500k-1m gas, so most of the time it's close to 1.5m gas per message.

How much gas is this? Was worried it might be over the block limit :D

Hi Kevin! Sorry for the late reply, somehow missed the notification. The signing happens in the application (eg Warpcast or Supercast), this is where the private key is stored.

Do you have any documentation or open-source code links on where the signature for each click happens and where the private keys are stored that are doing the signing, stuff like this?  Assuming the user (clicker) is not signing anything per click?
