According to ChainCatcher, on the evening of December 18th (Eastern Time), Circle officially announced that Cygnus has joined the Circle Alliance to promote the large-scale adoption of USDC.
Cygnus drives USDC adoption by bringing Instagram users to on-chain activity through its embedded wallet experience and multi-chain integration. By using USDC as the foundation for its Instagram App Layer, Cygnus enables seamless on-chain login, deeper user engagement, and expanded access across EVM and non-EVM networks.
