Solana co-founder: There are currently no engineering technical barriers to building a cross-chain bridge aimed at Ethereum L1 on Solana.

Golden Finance reported that Solana co-founder toly published on the X platform stating, “All existing Layer 2 networks (L2) have a required authorization multisignature mechanism that can overturn cross-chain bridges contracts without prior notice.” The “escape passage” (referring to the emergency withdrawal mechanism for cross-chain assets in extreme cases) is not a characteristic of layer two networks, but rather a characteristic of cross-chain bridges. Currently, there are no engineering technical barriers preventing the construction of cross-chain bridges on the Solana blockchain that are oriented towards the Ethereum Layer 1 network. In other words, it allows Ethereum L1 to become a “Layer 2 network” for Solana, while providing complete withdrawal guarantees for cross-chain assets. Achieving this does not require any modifications to Ethereum, and as the implementation difficulty of Ethereum L1 zero-knowledge proof (Zk proving) technology decreases, the difficulty of building the aforementioned cross-chain bridges will also decrease.
