If you're working on a Farcaster client, esp. if it does write actions, and I didn't include it here, please reply to this cast. https://warpcast.com/dwr.eth/0x23c330
Working on casterscan.com which will have write actions(in addition to some other features from early feedback) soon 🫡
I'm planning to spend some more time on this in the near future: https://codeberg.org/aerique/MulTiPos#multipos But compared to the others you mentioned this is a really immature project.
