Cross-chain interoperability has been gaining steam as a solution which allows users to enjoy the benefits of multiple protocols simultaneously. Prior to the popularisation of cross-chain interoperability, most blockchain protocols were walled gardens, isolated from access to the assets and data of others. Cross-chain interoperability kills two birds with one stone; it is also a powerful Layer Two scaling solution which will help the Centaur Chain avoid the kind of congestion which has besieged Ethereum.
With the ever increasing number of protocols and their varying niches, crypto enthusiasts are often required to work with multiple wallet applications. This would extend to various sets of seed phrases and public/private keypairs and result in confusion at scale.
One primary reason contributing to this problem is that wallets are built with a specific protocol or technology in mind. For instance, Metamask was designed for Ethereum and is currently cross-compatible with EVM chains such as the Binance Smart Chain and Polygon. However, it is not inter-operable with protocols that are built on different underlying technologies such as Bitcoin, Polkadot and Solana, all of which have achieved non-neglectable levels of adoption.
As such, the key goal of Hadar was to be a wallet that directly addresses this flaw by being built for the blockchain industry as a whole, instead of focusing on a specific protocol or technology. This means that users can login with one set of credentials and gain access to their entire portfolio across all the integrated protocols. At present, Hadar supports Bitcoin and Ethereum (including all ERC20 tokens). Beyond this, the plan is to onboard EVM compatible chains and move on to other technology stacks such as Tendermint Core and Substrate based chains.
