The purpose of this repository is to enable smart contract interchain communication within a Cosmos chain. The gate contract serves as a core component and offers a range of functionalities to facilitate seamless communication between interconnected chains.
The gate contract allows contracts within the same chain to send messages to remote contracts in other Cosmos chains or perform queries on remote chains. It achieves this by leveraging IBC packets to securely transfer information between chains. Additionally, the gate contract provides support for transferring up to one native token within the requests, allowing the seamless exchange of assets across chains. Multiple requests can send different amount of native token, but the channel used to transfer and the denom must be the same.
One notable feature of the gate contract is its ability to process multiple requests within a single transaction. Developers can include multiple requests in a single transaction sent to the gate contract, and all these requests will be consolidated into a single IBC packet. This enables multiple executions on the remote chain in an atomic manner, ensuring consistent and reliable interchain interactions.
In situations where a native token needs to pass through an intermediate chain to obtain the correct denomination on the destination chain, the gate contract supports packet forwarding. This feature ensures that native tokens can be routed through intermediate chains as needed to ensure the successful transfer of assets to the desired destination chain.
Within the request sent through the gate contract, it is possible to include a fee for the relayer. This fee can be provided from the sender contract as native token. The fee serves as an incentive for relayers to process and forward the request to the destination chain.
The overall goal of the gate contract is to provide a robust and flexible solution for interchain communication for smart contract, enabling developers to build complex and interconnected applications within the Cosmos ecosystem.
