The identity oracle project Clique tweeted that its attestations are now available on the PolygonID App, and the first iteration will be Sybil proofs based on the user's Twitter credentials. Clique said that some future partners can use these credentials, including Guild. These initial credentials will be used for anti-Sybil attacks and proof of humanity in Dapps supported by PolygonID.

In October last year, Clique completed a US$3 million seed round of financing, with participation from GGV Capital, Qiming Venture Partners, Alliance DAO, SevenX Ventures, Infinity Ventures Crypto (IVC), SNZ Holding, Sky9 Capital, smrti lab, Mirana Ventures, DWeb3, Formless Capital, Redline DAO, Mask Network, Puzzle Ventures and others.
