HAVAH is a trustless interchain infrastructure that enables people to easily and safely move their digital assets from one blockchain to another. HAVAH utilizes a heterogeneous relayer method for transferring digital assets, making it more secure and scalable compared to other bridges or interchain services. To enhance security and independence, we have developed our own specialized mainnet for interchain and multichain contents. One of our key interchain contents is a game that accepts various NFTs from different blockchains. Our goal is to provide not only the infrastructure for asset movement but also engaging content to encourage asset migration.
