What Is Employee Growth Rate & Why Is It Important?

Composable Finance is creating infrastructure to unlock the multi-layer, and multi-chain future of Ethereum, and other layer 1 blockchains. At present, the lack of compatibility between blockchains and layers results in disparity and inefficiency. Developers are very restricted in what they can build with siloed infrastructures, and users are forced to navigate complicated and lengthy processes if they want to utilize multiple chains or layers. With our products, we intend to reduce these barriers that DeFi creators and users face. We first bridge the gap between different Ethereum Layer 2 implementations, and then unlock further interoperability by allowing smart contracts.
