Solana Co-Founder: L2 Promises Fall Short as Upgrade Multisig and Cross-Chain Bridge Risks Endanger Users

COINOTAG News reported on Oct 27 that Solana co‑founder Toly joined a social media discussion, warning that Layer 2 promises often outstrip what is deliverable.

He argued that a secure, high‑performing L2 stack remains unlikely given code complexity and large attack surfaces, pushing projects toward an upgrade multisig model that can undermine initial security guarantees.

In a worst‑case scenario, these designs mirror Wormhole, where a multisig could drain funds from a cross‑chain bridge.

By contrast, Sui validators cannot act unilaterally; overnight patches would be rejected by major nodes, potentially pausing the network. For users, this flags elevated cross‑chain risk.

Investors should monitor audits, governance updates, and bridge controls as interoperability remains important but requires disciplined risk management.
