Chain Abstraction
Chain Abstraction powered by Everclear allows users to seamlessly interact with dApps from any chain using any token, without leaving the UI. Let’s explore what Chain Abstraction is.
Chain Abstraction
Streamlining Crosschain Interactions
By abstracting blockchains, Everclear enables dApps to provide their users with seamless crosschain experiences. Chain Abstraction empowers dApp users to access the different functions of an application regardless of which chain they are on and which token they hold.
Why is Chain Abstraction Needed?
Successful dApps ensure that the user experience is as seamless as possible, allowing the greatest number of individuals to use the dApp.
The end users of a given dApp shouldn’t have to deal with the technical complexities of an application, such as the blockchain they are on and the token used. Ideally, interacting with a given dApp is so smooth that end users may not even realize which chain they are operating on and which tokens are used.
To accomplish a seamless user experience across blockchains, tokens, and applications, Chain Abstraction is needed.
The Shortfalls of an Expanding Ecosystem
The continuously expanding blockchain ecosystem requires dApps to expand their functionalities to various blockchains. As a result, their users face a variety of hurdles that result in a poor user experience and often high gas costs.
Unifying the Siloed DeFi Landscape
The DeFi landscape is siloed and spread across multiple blockchains and L2 solutions. Users wishing to access different financial products need to move assets from one provider and/or blockchain to another, incurring high gas costs and potential opportunity costs in the process.
Blockchain agnostic platforms that utilize Chain Abstraction to allow their users to access different DeFi dApps and blockchains from a single application address this challenge.
The Advantages of Chain Abstraction
Abstracting blockchains offers compelling advantages for both end users and developers. Let’s have a look at the benefits.
Seamless UX
End users benefit from seamless UX and can use the app on their preferred chain. Bridging, swapping, and covering gas costs is all done under the hood in a single transaction.
Simplicity
Integrating Chain Abstraction is straightforward thanks to Everclear's lightweight toolkit and does not require contract changes or audits.
Adaptability
Everclear's toolkit for Chain Abstraction is future proof, allowing developers to integrate new chains without engineering overhead.
Your dApp Before & After Chain Abstraction
With Chain Abstraction, you can offer your users a beacon of simplicity and seamlessness in an ecosystem that is heavily fragmented and complex.
Transaction Flow
Let’s have a look how the transaction flow looks like (under the hood). To better illustrate this, we are going to use a scenario in which a dApp user enters a USDC lending position on Polygon with funds from Optimism.
From the perspective of the end user, all that is required is to connect their wallet and begin lending. The underlying processes of the app initiating a crosschain transaction from Optimism to Polygon is not noticeable to the user.
- 1User initiates transaction to deposit into a pool with funds on Optimism
- 2Application forwards relevant data (USDC, calldata, txn details on Polygon) and target on destination chain
- 3Everclear makes transaction to the target, passing the specified USDC and calldata
- 4Calldata is unpacked, supply function of app is called
