Router Protocol is a cross-chain communication protocol, that can not only enable the transfer of assets but can also support the passing of arbitrary data across chains. Developers can leverage its infra to build diverse cross-chain applications with ease. Router Protocol has built an open-source developer tooling suite that includes a CrossTalk smart contract library, a NodeJS SDK, a cross-chain block explorer, and other tools to help with the continuous integration and development of cross-chain dApps.
