How Is Rubic’s Best Rate Finder App Exploring Chain Abstraction?

At Rubic, we are constantly exploring ways to make the cross-chain experience smoother and more accessible. Chain abstraction aligns perfectly with our vision of a borderless and user-centric Web3 future. We are actively researching and implementing solutions that leverage chain abstraction to empower users and developers alike.

Chain Abstraction Principles and Rubic

Chain Abstraction is a hot but still emerging topic. It mainly stays in the realms of theory, but already started to see some real-life solutions. One of the best articles which summarise various theoretical approaches and emerging solutions is the one by Four Pillars.

It provides a comprehensive framework which demonstrates how Rubic’s design goes well in line with the Chain Abstraction Principles.

Chain Abstraction Principles	Rubic
Asset Management Abstraction: Users can manage and interact with their assets across different blockchain networks through a single interface, without needing to understand the technical details of each network.	Rubic’s Best Rate Finder App now features “All Chains”, a powerful addition that enhances the chain abstraction experience. This new category provides a seamless way to explore the most popular tokens across all supported blockchains in a single view.Furthermore, users can now easily locate a specific token on every available chain, simplifying cross-chain asset discovery and trading.
Transaction Abstraction: Users can initiate transactions without needing to understand the underlying blockchain protocols, as the system bundles and processes transactions in batches.	Thanks to Rubic’s smart routing feature, users experience transactions as a one-click action, while all the complex processes are seamlessly managed behind the scenes by Rubic.
Token Bridge Abstraction: Users can seamlessly transfer assets across different blockchain networks without needing to understand the technical details of blockchain bridges or wrapped tokens.	As the Best Rate Finder, Rubic aggregates over 90 blockchains & 360+ DEXs and bridges, enhancing the smart router feature to eliminate the need for users to understand the complexities of trading across different blockchains.Aggregated bridges and DEXs handle all the work for users, whether it’s a cross-chain or on-chain trade.
Multi-Chain Abstraction: Users can interact with smart contracts and applications across multiple blockchain networks through a unified interface, without needing to switch between different wallets or interfaces. This can be done with message bridges, or a solver.	On Rubic, users can seamlessly swap assets to, from, and across EVM, non-EVM, and Layer2 chains, all within a single interface. When swapping to non-EVM chains, for example, one doesn’t need to log in to a non-EVM wallet (like for Bitcoin, Ton, etc.) and simply enter the receiver’s wallet address on a non–EVM chain without needing to log in twice.
