Recent developments across major blockchain networks are shaping the landscape this week. Solana rolled out Kora, enabling zero-fee transactions with support for custom fee tokens—a significant move toward cost-efficient blockchain operations. Meanwhile, Trust Wallet users faced a security scare as a browser extension breach resulted in over $6 million being drained from affected wallets, prompting immediate security reviews. On the recovery front, Gnosis chain executed a hard fork to reclaim $9.4 million lost in the Balancer exploit, demonstrating community-driven remediation efforts. These updates reflect ongoing innovation, security challenges, and resilience mechanisms across the Web3 ecosystem.
