How to understand chain abstraction? In the eyes of IQ100, chain abstraction = liquidity pool bridge + account abstraction + social account login.

This understanding is actually knowledgeable and, to some extent, common sense in the industry. But the question is, does this common sense help us to truly understand chain abstraction or hinder us?

I killed time by reading Taleb's bestseller The Black Swan on the plane to Bangkok. The writer, who was a trader, cited a lot of personal experiences as cases to prove to readers the harmfulness of popular common sense that is "well-known and self-evident". The end of our world is not smooth and evenly distributed. "Disruptive innovation" and "exponential growth" come from the chaos of time and the fractal of space.

Chain abstraction is the third stage of the evolution of blockchain architecture in the time dimension: integration (monopoly chain) - division (modular public chain) - integration (chain abstraction): integration.

Abstraction is a common construction method in computer engineering, which usually refers to simplifying complex systems into a form that is easy to understand and operate. In terms of chain abstraction, its function is to simplify complex chain operations (mnemonics, GasToken, cross-chain, intent interpretation and execution, etc.) into a form that is easy for users to understand and operate. This paradigm innovation occurs not only at the UX layer, but also at the Infra layer and the middle layer.

For example, in the field of cross-chain bridges, we see that in addition to the original two paradigms of mass/liquidity pools, the Solver Network/Filler Network paradigm that decouples inter-chain messaging from liquidity provision is emerging. Taking the cross-chain solution of Uniswap x Across as an example, this problem is solved by adopting the cross-chain order structure standardized by the ERC-7683 standard and the unified Filler Network. Synapse innovatively introduced AI Agents as automated arbitrageurs of the Solver Network to achieve the intention bridge of instant settlement. EverClear has transformed from a cross-chain bridge to a professional clearing layer protocol.

For example, in Ethereum’s upcoming Pectra upgrade, EIP7702 will allow EOA addresses to point to smart contract (account abstraction) addresses after being signed, giving EOA addresses programmability and the ability to use advanced features such as multi-signatures, custom batch transactions, one-click circular staking/borrowing, and automatic Yiled compounding.

For example, in the wallet field, Safe Wallet creates smart contract wallets for N EVM chains while launching 1 signature, and the addresses of these wallets are the same, which greatly simplifies the complexity of users managing smart contract wallets.

In general, as Lydia mentioned in her long tweet: Chain abstraction is not only a change in UX, but also a comprehensive paradigm shift. These changes were not initially perceived by the public and were small iterations, but they will eventually rapidly reshape the architecture of blockchain and the industry landscape of Web3.
