Absinthe Protect is the interoperable web3 standard for bot detection and multi-accounting. It leverages dozens of signals in a privacy-preserving way with 99.5% detection accuracy.


Questing platforms use Absinthe Protect as a proof-of-humanity quest action.

They use this information to give bots more tasks/on-chain actions, filter them out, and for analytics when preparing for an airdrop.

Zeekaptcha is the world's first web3 captcha. It is an open-sourced public good used to create on-chain reputation and on-chain Sybil protection through a proof-of-captcha.
