How Can Cross-Chain Projects Open Up Growth Opportunities of Layer2 Interaction?

Layer 2 solutions have grown in popularity over the past year due to Ethereum’s network congestion and soaring transaction fees. These solutions help DApps scale by taking transactions off-chain, but whether they can trigger a massive boom in on-chain transactions requires more refinement. This article will focus on the cross-chain solution projects that I have been following for a long time: Celer Network, Hop Protocol and Connext Network. Celer uses its own State Guardian Network (SGN) to ensure cross-chains interoperability and security.
