Abstract Network Snapshot
Consumer-focused Ethereum L2 built on ZKsync's ZK Stack with EigenDA for data availability, developed by Igloo Inc. — the parent company of Pudgy Penguins. Abstract targets mainstream consumer apps like gaming, streaming, and social, with the Abstract Global Wallet onboarding users through passkeys and social login instead of seed phrases.
