What are the highlights of Solayer's launch of the SVM native cross-chain bridges?
Seeing that Solayer is about to launch its own SVM native cross-chain bridges. To be honest, in the context of continuous hacks on cross-chain bridges and interoperability among countless chains, talking about "cross-chain bridges" always gives me a feeling of concern. So what different ideas does Solayer have this time? Let me share my understanding:
Unlike traditional cross-chain bridges that rely on multi-signatures or relay nodes, Solayer uses the SVM native proof-based mechanism. In simple terms, it generates cryptographic proofs of asset transfers directly at the Solana virtual machine level, rather than relying on the "honest assumption" of external validators. Specifically: it adopts a no-database architecture + pure PDA (Program Derived Address) logic. Traditional cross-chain bridges typically need to maintain a centralized database to record cross-chain states, which becomes a primary target for hackers. In contrast, PDA is a unique deterministic address generation mechanism in Solana, where all states exist directly on-chain and are derived through program logic. To put it another way, it's like changing the way the safe's password is recorded from paper notes to a mathematical formula derivation — even if hackers obtain some information, they cannot cause harm without the complete on-chain state.
Solayer has introduced the Guardians mechanism, employing stateless operations — Guardians make no assumptions about historical states. More critically, it sets an instance bridge cap limit, allowing for control over the extent of losses even in the event of security issues. In this regard, the Fuzzland team has conducted formal verification of the entire system, equivalent to using mathematical methods to prove the correctness of code logic rather than relying solely on testing. Coupled with on-chain replay protection, 24/7 anomaly monitoring, and real-time alerts, it has at least theoretically established multiple layers of protection.
Solayer supports Cross-Chain Calls and composable Hooks functionality. With Hooks, developers can automatically trigger on-chain operations like arbitrage and liquidation after transactions. If this composability is combined with cross-chain capabilities, it will indeed open up many new possibilities. That said, it is not without challenges; the design of not requiring a whitelist does lower the barrier to entry, theoretically allowing any token to be bridged, which undoubtedly brings security challenges and regulatory risks. At the same time, established cross-chain bridges like Wormhole have been deeply rooted in the Solana ecosystem for a long time, making it difficult for Solayer to gain market share. While there is technological innovation, the cross-chain bridge sector ultimately needs to be validated for security with real money.
