Over the past year, we have witnessed the exponential growth of Layer2 ecosystem, such as Polygon, Avalanche, Optimism, and Arbitrum. Although, there are official cross-chain bridges, however, it takes long time (7 days) to cross back to the mainnet. To solve this problem, there are few cross-chain platforms, that provide instant liquidity to users to cross among different chains. Based on my research and hands-on experience, I have found the following cross-chain platforms, that are safe, us...
