In the growing world of blockchain, handling different chains poses a challenge, making it tough for users, especially developers. Cross Chain Messenger Protocols aim to solve this, but face issues with limited chain support, varied fees, syntax differences, and more. To address these challenges, CrossSync Protocol provides a common gateway for multiple interoperability protocols. Users interact with the CrossSync Protocol Gateway, simplifying the process. It converts payloads for different messenger protocols, making it user-friendly and eliminating integration complexities.

Benefits:

A common relayer fee simplifies developer integration. Combining various protocols into one enables cross-chain messaging on almost all chains. Auto Routing ensures the lowest fees for cross-chain calls. Modular design allows easy integration of any protocol. Benefits users and developers in terms of UI, fees, ease of use, integration, etc. Operates on-chain through secure smart contracts.Why We are Novel/Better than alternatives: There is no direct protocol that does this. No one has focused on cross-contract calls. There are dex and bridge aggregators which do this but they don't focus on message/liquidity passing as such and also they are limited to chains due to their architecture. They are also more focused on off-chain decision-making for bridging things whereas we are focusing fully on on-chain decision-making and message passing. Our Focus is to build a protocol that is as simple as connecting to any chain that launches tomorrow and also provides an aggregated gateway to all the messengers in the ecosystem, such that as a developer you are not constrained to use a single messenger on a network. We also provide a unified interface to all messengers so if you are using a single messenger and want to switch to another messenger at any time, you can do it easily by just switching the routeId. All the input parameters will remain the same! For Example: Let's say your dapp is using Axelar and you are available on 10 chains that Axelar supports but suddenly a new super chain comes into the market that has its messenger from optimism to super chain only but is not available to be connected to other chains as axelar is not supporting that. Now how will you do cross-contract calls to this new super chain? You have to find different messengers that do that which is time-consuming and code change is required or maybe it's even not available. But with crosssync, as soon as superchain messenger is deployed we will connect it in crosssync. Now You can send cross-contract calls from polygon to superchain in this way: polygon to Optimism using Axelar and Optimism to Superchain using native messenger. To do all this You don't need to integrate those individual messengers in your code or figure out things on your own as crosssync will handle all this through manual or automatic routing in the contract. I feel we will be the protocol using which others can build their own cross-chain dexes, apps, bridges, etc in the least time which will bring interoperability to a new level in the web3 ecosystem. Also, our focus is a smart contract protocol and not the SDK kind of protocol. We want to give a fully on-chain solution!
