frames

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!

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

Nvm https://github.com/pavlovdog/farcaster-solidity, seems like 2m-ish gas? Would be curious to see in a transaction. I wanted to use this in a 4337 wallet, but was a bit concerned because of lack of nonce

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.

I guess moving to ZK can reduce it to 500k. If a multisig quorum or TEE as a coprocessor is acceptable, it can be as low as a single ecdsa verification.
