Community clanks combine mechanisms from the existing Clanker v4 dev buy and presale extensions to give early supporters and existing communities access to newly launched tokens at the best possible price, while establishing a liquid pool for trading.

How it works

Participants contribute ETH to a “group dev buy” and make the first swap in a newly created pool, guaranteeing the best possible price.

Setup

Before launching, the deployer chooses:

• A target goal amount. For example, 10 ETH.
• A contribution cap per participant For example, 0.1 ETH.
• An optional allowlist with individual contribution caps per participant.
• A lockup and vesting schedule for participants.
• A portion of the goal amount to reserve as ETH to deployer, up to 50%.

The Community Clank extension collects first-come first-served contributions for a period of time. If it fails to meet the minimum goal, participants can withdraw their contributions. Projects may use allowlisting to ensure fair distribution to specific participants, and use the rich data available from the Farcaster social graph to select them.

Launch

If the goal is met, the token is deployed. A portion of the raised ETH is sent to the deployer and the remainder is used to perform the first swap into a new pool. Tokens vest to participants over time.

Projects get the ability to allowlist early believers and existing communities and collect a portion of the ETH raised. Participants get guaranteed access at the best possible price. Traders get a trustworthy liquid pool at launch that works just like other Clanker launches.

Who is this for?

We think this is a good way to raise up to ~10 ETH from 100-1000 participants, distributing 10-25% of token supply. It’s best for projects with a small community of early supporters who prefer the Clanker v4 fair launch model.

How is this different than a regular Clanker fair launch?

Sniping is the main challenge in any fair launch: the earliest to act can purchase a large share of supply, which rewards bots, not believers. Clanker’s anti-sniping mechanisms slow down snipers and redistribute fees to projects, but they don’t guarantee early access. In a Community Clank, participants buy before snipers.
