Chain abstraction (ChA) is a term that has gained substantial usage since 2024. It helps make apps more attractive to the end user and helps developers create more efficient apps that allow cross-chain interaction. In fact, ChA is more of a user experience rather than a technology.

Since blockchain interaction can be relatively complex, this guide will explain the meaning and basics of chain abstraction.

What Is Chain Abstraction?

ChA is an emerging trend, prioritized by NEAR, that facilitates users’ interactions with blockchain technology by separating it from the UX (user experience). The goal is for users to be unaware of the particular blockchain they are interacting with or even that they’re using a blockchain at all.

Chain abstraction aspires to unite the fragmented blockchain landscape, facilitating seamless interactions throughout networks without the need for users to navigate the complexities of the chains. This addresses two common problems in blockchain’s adoption: fragmentation and complexity. It also represents a crucial transfer towards interoperability and user-friendliness in the blockchain sphere, improving accessibility and usability for both developers and users.

What does on-chain mean? It refers to transactions on a blockchain that have been authenticated and verified.

The Basics of Chain Abstraction and How Chain Abstraction Works

Now that you know what blockchain abstraction is, let’s discuss its basics. These pillar value prepositions solve the UX and liquidity/fragmentation issues. They all have substantial power and widespread application to revolutionize the blockchain space.

An Optimized UX

Nowadays, users who interact with decentralized applications throughout a multi-chain ecosystem need to manage several balances, wallets, and addresses and stay aware of the technical differences of blockchains. This issue is one of the primary reasons why dApp adoption is still limited globally.

Chain abstraction makes Web3 much easier by eliminating inter-chain barriers. This allows users to seamlessly use applications without being concerned about the origin chain of their funds or the base chain of their chosen application, as these details become insignificant to them. Ultimately, users are no longer burdened with the complexities of navigating the Web3 environment.

ChA separates blockchain infrastructure from the UX, allowing for seamless interaction with dApps throughout many chains via one interface. This benefits users as they don’t have to switch networks, manage several wallets, or handle multiple chain-specific gas fee denominations. ChA aspires to achieve such a user experience.

Defragmenting Users and Liquidity

Fragmentation is another factor that impedes dApp development, frequently forcing developers to pick a blockchain depending on its co-marketing opportunities, liquidity, and user access instead of technical needs.

ChA enables developers to build using the latest available technology with no need to feel forced to pick a single blockchain or a small set of blockchains. It facilitates the transition of users and liquidity in Web3 from being confined to a specific ecosystem to becoming a globally traded commodity among applications.

The need for chain abstraction increases as Web3 shifts from a closed ecosystem of general chains to a modular one with multiple specialized chains. Lately, developers have begun building application-specific blockchains instead of settling for apps built on larger and generalized blockchains. Without ChA, this road to scaling would face substantial fragmentation to the ecosystem.

Simplified Development

ChA allows developers to have the flexibility to develop dApps with no limitations to a specific blockchain’s constraints. A developer can use Polygon for cost efficiency while using Ethereum for its smart contracts. For example, Decentraland uses Polygon to enable its users to buy, claim, trade, and sell avatar wearables without transaction fees.

Chain Abstraction Examples

If you are looking for ChA in action, let’s take a look at some examples:

  • Multi-chain NFT platforms: Some marketplaces support NFTs from several blockchains, enabling users to sell, buy, and monitor NFTs throughout different networks via one platform interface. So, users don’t have to navigate numerous blockchain-specific NFT marketplaces.
  • Cross-chain DeFi platforms: These platforms allow users to use different blockchains to swap tokens without the need to use separate bridges or exchanges. There’s only interaction with one interface, and the platform is responsible for the cross-chain mechanics.
  • Blockchain-agnostic dApps: Some dApps are specifically developed to operate on several blockchains at the same time. For instance, a gaming platform can enable players to use assets from Binance Smart Chain, Ethereum, and Polygon without caring which blockchain the assets are on. The game simplifies the chain-specific details and focuses on in-game and gameplay economics.
  • Protocol-level abstraction: Projects like Polkadot and Cosmos enable different blockchains to interoperate seamlessly, simplifying chain abstraction crypto at the protocol level. They allow assets and data to move freely across chains through their inter-blockchain communication protocols, simplifying the complexities for users and developers.

Conclusion

Chain abstraction is a trend that facilitates users’ interactions with blockchain technology by separating it from the UX. It aspires to unite the fragmented blockchain landscape, facilitating seamless interactions throughout networks without requiring users to navigate the complexities of the chains.

The basics of ChA are an optimized UX, defragmenting users and liquidity, and simplified development. Some examples of ChA include multi-chain NFT platforms, cross-chain DeFi platforms, blockchain-agnostic dApps, and protocol-level abstraction.
