LI.FI Introduces LI.FI 2.0
LI.FI, a bridge aggregation protocol, introduced LI.FI 2.0, an upgrade that enhances its liquidity aggregation by integrating an intents protocol and supporting any interop token standard. LI.FI 2.0 incorporates Catalyst, an intents protocol that streamlines order execution across various virtual machines through an open marketplace of solvers. LI.FI also developed Pioneer, an in-house solver capable of supporting any chain, regardless of the virtual machine used. The upgrade will facilitate permissionless participation and incorporate Glacis to assist interop token standards, enabling smooth asset transfers across different chains without compromising liquidity.
Abstract Post Mortem On Cardex Incident
Abstract, a consumer-oriented rollup built on ZKsync's ZK Stack, released a post-mortem regarding a breach involving a private key leak at Cardex, a gaming app featured on the Abstract Portal, resulting in over $400k in user funds being compromised. The issue stemmed from Cardex exposing the private key on their website front end. Using a single session signer shared across all users, an attacker managed to siphon ETH from approximately 9,000 wallets. Notably, ERC-20s and NFTs remained unaffected due to their exclusion from the session keys' permissions. Abstract is advising all users to revoke any open session keys via a dedicated portal and is currently working with security teams on fund recovery efforts.
