As Web3 continues to scale rapidly across a growing ecosystem of Layer 2s and rollups, the challenge of fragmented user experiences has become more pressing than ever. Users now juggle multiple wallets, gas tokens, and account addresses across chains—creating friction that hinders mainstream adoption. This is where chain abstraction enters the picture: a transformative approach to unify multi-chain asset and account management, effectively dissolving the barriers between blockchains.
Chain abstraction isn’t just about convenience—it’s about redefining how users and developers interact with Web3. It aims to solve core issues like cross-chain communication, gas payment flexibility, and account portability, offering a seamless experience regardless of the underlying infrastructure. While the vision is clear, the path to achieving it varies widely among projects, each bringing unique architectural designs and strategic motivations.
This report explores the diverse approaches to chain abstraction, analyzing how leading projects are shaping the future of interoperability, liquidity, and user experience in Web3.
Comprehensive Chain Abstraction: Leading Projects and Strategies
Chain abstraction represents a meta-solution for Web3’s fragmented landscape. Rather than focusing on a single technical hurdle, comprehensive solutions aim to tackle multiple challenges at once—cross-chain transactions, unified accounts, gas abstraction, and shared liquidity.
Several major players are pioneering this space with distinct strategies:
NEAR Protocol: Unified Account Control via MPC
NEAR offers a live chain abstraction solution built on Multi-Party Computation (MPC) and threshold signature schemes. Its system allows users to generate multiple external accounts (EOAs) across EVM and non-EVM chains—all controlled by a single NEAR account. NEAR nodes participate in collective signature generation, enabling cross-chain transactions without exposing private keys.
This architecture centralizes account control within the NEAR ecosystem. While users can initiate transactions on any chain using their NEAR-based identity, they must still fund each target chain independently. This means gas costs aren't abstracted away entirely—but the ability to manage multiple chains from one interface is a significant UX leap.

Polygon’s AggLayer: ZK-Driven Liquidity Aggregation
Currently in testnet, Polygon’s AggLayer focuses on unifying chains built with its Cross-Chain Development Kit (CDK). It aggregates zero-knowledge proofs (ZKPs) from CDK-based L2s and submits them collectively to Ethereum for settlement.
By bundling proofs and enabling shared liquidity through ETH as an intermediate token, AggLayer addresses the common problem of isolated liquidity on new L2s. However, its scope is currently limited to CDK chains, making it an ecosystem-specific solution rather than a universal one.
Optimism’s Superchain: Interoperability Through OP Stack Unity
Still in the concept stage, Optimism’s Superchain shares AggLayer’s vision but applies it to chains built on the OP Stack. The goal is to create a network of interconnected blockchains that share security, messaging, and bridging capabilities.
Developers benefit from consistent tooling and composability across chains, while users gain seamless access to applications regardless of which OP Stack chain they’re deployed on. Like AggLayer, this is an ecosystem-centric model—designed to strengthen Optimism’s developer network rather than provide cross-ecosystem abstraction.
Particle Network: Universal Accounts & Cross-Chain Liquidity
Particle Network stands out with its testnet-stage modular L1, designed specifically for chain abstraction. Its Universal Account protocol enables users to maintain the same address and balance across all connected chains. Powered by a decentralized bundler and messaging network (built on Hyperlane), Particle automates cross-chain swaps and transactions.
A key innovation is gas abstraction: users can pay transaction fees in any token, with settlements occurring on Particle’s Cosmos SDK-based L1. This eliminates the need to hold native gas tokens on every chain—a major pain point for average users.
Moreover, Particle integrates heterogeneous chains like Bitcoin and Solana, allowing any wallet to act as a controller for a Universal Account. This broad compatibility makes it one of the most inclusive approaches in the space.
Why Different Approaches? Context Shapes Design
The diversity in chain abstraction strategies stems from differing origins and incentives:
- Polygon and Optimism are rooted in Ethereum scaling. Their chain abstraction efforts extend their existing ecosystems, encouraging developers to build CDK or OP Stack chains knowing they’ll benefit from shared liquidity and communication.
- NEAR, originally a high-throughput sharded L1, leverages its node infrastructure to offer cross-chain signing. Its focus is on becoming a central coordination layer for multi-chain identity.
- Particle Network evolved from a Web3 developer services provider—the largest Account Abstraction (AA) infrastructure with over $2B in secured assets. With products like BTC Connect (the first AA layer for Bitcoin L2s), Particle already has a vast base of smart accounts. Its modular L1 is designed to onboard these users into a fully abstracted multi-chain experience seamlessly.
This background explains why Particle prioritizes developer tooling and universal access, while others focus on strengthening their own ecosystems.
Cross-Chain Liquidity & Transaction Execution: The Hidden Engine
For true chain abstraction to work, seamless cross-chain swaps and message passing are essential. Here’s how each project handles liquidity and execution:
- NEAR: Uses its native token as gas; cross-chain swaps occur via signatures generated by MPC nodes.
- AggLayer: Relies on ETH as an intermediate swap token; liquidity is coordinated post-settlement.
- Superchain: Also uses ETH for bridging; low-latency messaging via modular proof systems.
- Particle Network: Features a Universal Liquidity protocol where decentralized solvers and DEX aggregators facilitate swaps across chains. Gas payments in any token are settled on Particle’s L1.
Particle’s use of a decentralized solver network—eventually replacing initial liquidity providers—positions it for long-term scalability and decentralization.
User & Developer Experience: Bridging the Gap
Ultimately, the success of chain abstraction hinges on UX and DevX improvements:
- Polygon & Optimism: Offer strong developer experiences within their ecosystems. New L2s gain instant access to shared liquidity and communication tools, reducing go-to-market friction.
- NEAR: Provides powerful tools for dApp developers—NEAR smart contracts can sign transactions on other chains too—but requires manual funding of target chains, limiting full UX abstraction.
Particle Network: Delivers the most holistic improvement. Developers integrate Universal Accounts via a simple SDK. Users enjoy:
- One account across all chains
- Ability to pay gas in any token
- Instant control over smart accounts on EVMs, Bitcoin L2s, Solana, etc.
- Minimal latency overhead for cross-chain actions
This level of integration dramatically lowers the barrier to entry for non-technical users—a critical step toward mass adoption.

FAQ: Your Chain Abstraction Questions Answered
Q: What is chain abstraction?
A: Chain abstraction is the process of hiding blockchain complexity from users—enabling seamless interactions across multiple chains without requiring them to manage separate wallets, gas tokens, or bridges.
Q: How does gas abstraction work?
A: Gas abstraction allows users to pay transaction fees in any token. The system automatically converts that token into the required native gas (e.g., ETH, MATIC), often via automated cross-chain swaps.
Q: Can chain abstraction work across non-EVM blockchains?
A: Yes—projects like Particle Network support heterogeneous chains including Bitcoin L2s and Solana, proving that true cross-chain interoperability is achievable beyond EVM compatibility.
Q: Is chain abstraction secure?
A: Security depends on implementation. Solutions using MPC (like NEAR) or decentralized messaging layers (like Hyperlane in Particle) reduce trust assumptions and enhance resilience against attacks.
Q: Do developers need to rewrite their dApps for chain abstraction?
A: Not necessarily. Many solutions offer SDKs or middleware (e.g., Particle’s Universal SDK) that allow existing dApps to integrate abstracted features with minimal code changes.
Q: Will chain abstraction eliminate bridges?
A: It won’t eliminate bridges but will make them invisible to users. Underlying cross-chain messaging protocols (LayerZero, Hyperlane) still power these systems—but they operate behind the scenes.
