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, a kind of industry common sense. But the question is, does this common sense help us truly understand chain abstraction or hinder us?

While reading Taleb's bestseller "The Black Swan" on the flight to Bangkok to kill time, the writer, who comes from a trading background, provides numerous personal experiences as examples to prove to readers the harmfulness of "well-known and self-evident" popular common sense. The end of our world is not smooth and evenly distributed; "disruptive innovation" and "exponential growth" arise from the chaos of the time dimension and the fractals of the spatial dimension.

Chain abstraction is the third stage of the evolution of blockchain architecture in the time dimension: merge (monolithic chain) - split (modular public chain) - merge (chain abstraction).

Abstraction is a common construction method in computer engineering, usually referring to simplifying complex systems into forms that are 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 forms that are easy for users to understand and operate. This paradigm shift occurs not only at the UX level but also at the Infra level and the middleware level.

For example, in the field of cross-chain bridges, we see the rise of the Solver Network / Filler Network paradigm, which decouples inter-chain messaging from liquidity provision, beyond the original massage/liquidity pool paradigms. Taking the Uniswap x Across cross-chain solution as an example, it addresses this issue by adopting a standardized cross-chain order structure based on ERC-7683 and a unified Filler Network. Synapse innovatively introduces AI Agents as automated arbitrageurs in the Solver Network, achieving instant settlement intent bridging. EverClear has transformed from a cross-chain bridge to a specialized clearing layer protocol.

In the upcoming Pectra upgrade of Ethereum, EIP-7702 will allow EOA addresses to point to smart contract (account abstraction) addresses after being signed, granting EOA addresses programmability and enabling advanced features such as multi-signature, custom batch transactions, one-click looping staking/borrowing, and automatic yield compounding.

In the wallet domain, Safe wallet has launched a smart contract wallet that creates N EVM chains with one signature, and these wallets share the same address, greatly simplifying the complexity of user management of smart contract wallets.

Overall, as Lydia mentioned in her long tweet, chain abstraction is not only a change in UX but also a comprehensive paradigm shift. These changes are initially not perceived by the public; they are fragmented iterations at the beginning, but will ultimately reshape the architecture of blockchain and the landscape of the Web3 industry rapidly and dramatically.

That's all.
