Solana founder Anatoly Yakovenko has highlighted the risks associated with Layer 2 solutions and cross-chain bridges like Wormhole, noting that both face similar vulnerabilities in worst-case scenarios. Yakovenko pointed out that multisignature setups can upgrade contracts and access bridged assets without user knowledge. He countered Gabriel Shapiro's assertion that multisignature architectures are more complex and harder to coordinate, emphasizing that the real issue lies in whether a set of non-user-controlled keys can directly manipulate funds, rather than the complexity of governance structures.
