What is Anoncast?
Anoncast is a zk-proof-powered anonymous posting tool that allows users to post anonymously to Farcaster and X (Twitter) by holding a certain amount of $ANON tokens. The ability to post and delete messages is governed by token requirements, ensuring onchain verification of anonymity.
How Anoncast Works
To use Anoncast, users must hold $ANON tokens:
Post to Farcaster: 5000 $ANON
Post to X (Twitter): 2,000,000 $ANON
Delete from X: 2,000,000 $ANON
The zk-proof integration ensures that identity is protected, while onchain token verification guarantees that only those meeting the requirements can post.
The Backstory of Anoncast
Anoncast was inspired by Superanon, a tool originally built by Woj, the creator of Super (a Farcaster client like Warpcast). Superanon was first used anonymously to summon @clanker, an autonomous memecoin creator, leading to the launch of a viral token that quickly caught the attention of the Farcaster community and Ethereum co-founder Vitalik Buterin.

Does this require a server? Is there a way to build it without a server, by making the farcaster account itself a smart contract that accepts a zk proof as its signature scheme?
At this time, @slokh expanded the concept into Anoncast as part of anonworld, bringing the idea of anonymous, onchain social interactions to life in a more structured way.
In a full-circle moment, both Woj and Slokh recently accepted roles at Merkle, the company building both Farcaster and the Warpcast client. What started as anon-driven experiments has now brought them together to work at the core of the ecosystem they helped shape.
Why I Find Anoncast Interesting
I was a long-time user of Super, created by Woj, long before Anoncast existed. One day, I was surprised to learn that a large amount of $ANON was donated to Woj by the community, and he distributed it to Super users. I watched the value rise (and fall) significantly, but I never tried Anoncast until recently with the v2 Frame.
For testing, I started by swapping ETH to $ANON inside the Warpcast Wallet. Then, within the Frame, I verified my 5000 $ANON minimum by creating a verifiable credential proof, which then unlocked my ability to post anonymously. The entire process was smooth from start to finish, and I was pleasantly surprised to see verifiable credentials in action.
As a company founder focused on building public goods around decentralized identity, I think I'll be using this a lot more often. The ability to interact anonymously yet verifiably is a compelling use case for zk proofs and could set a precedent for future anonymous social interactions. Decentralized anonymity is always a fascinating yet polarizing topic. While anonymity can protect free speech, it also comes with risks of misuse. Anoncast is one of the early experiments in token-gated, zk-powered anonymous posting, and I’m curious to see how this evolves.

Would I Use It Again?
Most likely. Anoncast is still an experiment, and I’m watching to see how developers respond to the open source resources, how users engage with it, and how moderation challenges are handled.
The big question: Can zk-based anonymous posting work at scale without being exploited? If so, Anoncast could set a precedent for future onchain social anonymity tools.
If you’re interested in privacy, zk-proof applications, or experimenting with anonymous posting, Anoncast is worth exploring. Let me know your thoughts!
