As Web3 adoption accelerates across a rapidly expanding ecosystem of Layer 2s and rollups, the user experience remains fragmented. Navigating multiple chains, managing disparate wallets, and handling gas in different tokens create friction that hinders mainstream onboarding. This growing complexity makes chain abstraction—a foundational infrastructure that unifies multi-chain asset and account management—not just a convenience, but a necessity.
Chain abstraction aims to dissolve the visible boundaries between blockchains, offering users and developers a seamless, unified experience regardless of underlying network differences. While the vision is clear, the path to achieving it is multifaceted, with various projects pursuing distinct architectural and strategic approaches. This report explores the current landscape of chain abstraction, analyzing leading solutions, their design philosophies, and their impact on user and developer experience.
Comprehensive Approaches to Chain Abstraction
Chain abstraction is not a single technology but an overarching goal achieved through multiple technical layers. Several projects are developing end-to-end solutions that tackle cross-chain communication, gas abstraction, identity unification, and liquidity aggregation simultaneously.
NEAR: Multi-Chain Account Orchestration via MPC
NEAR’s approach centers on account abstraction through Multi-Party Computation (MPC). By integrating threshold signature schemes into its node infrastructure, NEAR enables users to generate and manage multiple external accounts (EOAs) across EVM and non-EVM chains—all controlled by a single NEAR account.
This system allows users to initiate transactions on any connected chain without switching wallets or managing separate private keys. NEAR nodes collectively compute digital signatures for cross-chain operations, ensuring security while abstracting complexity. The NEAR token serves as the primary gas unit within this framework, capturing value through direct usage.

While powerful, this model requires users to fund each target chain independently. Although transaction signing is unified, asset portability isn’t fully automated—meaning users still face some manual overhead when moving liquidity across chains.
Polygon AggLayer: Unified Settlement for CDK Chains
Polygon’s AggLayer focuses on aggregating zk-proofs from Layer 2s built using its Cross-Chain Development Kit (CDK). These proofs are compressed and submitted collectively to Ethereum for final settlement, creating a unified security and liquidity layer for CDK-based chains.
The AggLayer functions as a "Unified Bridge," addressing the common issue of liquidity fragmentation among new L2s. By enabling seamless asset transfers between CDK chains and leveraging ETH as an intermediate swap token, it enhances capital efficiency across the ecosystem.
Although currently limited to CDK chains, Polygon has expressed ambitions to expand AggLayer’s reach to non-CDK networks. However, such expansion depends on external chain participation, making its near-term impact most significant within Polygon’s own ecosystem.
Optimism Superchain: Interoperable OP Stack Networks
Optimism’s Superchain vision mirrors AggLayer in principle but is built on the OP Stack—a modular framework for creating interoperable optimistic rollups. The Superchain aims to unify security, communication, and bridging across all OP Stack chains, allowing developers to deploy application-specific blockchains that can interact natively.
By standardizing infrastructure across rollups, Optimism reduces fragmentation and lowers entry barriers for new chains. Cross-chain messaging occurs with low latency thanks to modular proof systems combining fault proofs and ZK validity proofs.
Like Polygon, Optimism does not directly capture value from cross-chain swaps—its economic model relies on ecosystem growth rather than transaction fees from abstraction layers.
Particle Network: Universal Accounts and Shared Liquidity
Particle Network takes a holistic approach with its Universal Account protocol, designed to deliver true chain abstraction at the user level. Every user gets a single smart account address that maintains consistent balances and functionality across all supported chains.
This is powered by two core components:
- Universal Liquidity Protocol: Enables users to pay gas in any token, which is automatically swapped and settled on Particle’s Cosmos SDK-based L1.
- Decentralized Bundler & Messaging Network (DMN): Automates cross-chain UserOperations using Hyperlane for message passing and leading DEXs for swaps.
Unlike other models, Particle’s design supports heterogeneous chains like Bitcoin L2s and Solana, allowing any wallet to act as a controller for a Universal Account. This inclusivity broadens its potential user base and strengthens interoperability.

Contextual Drivers Behind Different Architectures
The strategic direction of each project reflects its origins and ecosystem goals.
- Polygon and Optimism evolved as Ethereum scaling solutions. Their chain abstraction efforts aim to strengthen their respective ecosystems by solving liquidity bootstrapping for new rollups.
- NEAR, starting as a high-throughput sharded L1, leverages its native account system to position itself as a central coordination layer for multi-chain identity.
- Particle Network began as a Wallet-as-a-Service (WaaS) provider and now serves over $2B in secured assets. Its transition into chain abstraction builds directly on its existing developer tools and large user base—especially through innovations like BTC Connect, the first account abstraction layer for Bitcoin L2s.
These differing starting points result in varied priorities: ecosystem lock-in versus open interoperability, gas abstraction versus full UX unification.
Cross-Chain Liquidity and Execution Models
Seamless cross-chain UX depends on robust liquidity and reliable message relaying.
| Project | Cross-Chain Mechanism | Gas Abstraction | Value Capture |
|---|---|---|---|
| NEAR | Node-based signature generation | NEAR token only | Direct (gas payments) |
| AggLayer | ZKP aggregation + ETH bridging | No | Indirect (ecosystem growth) |
| Superchain | OP Stack messaging + ETH swaps | No | Indirect |
| Particle Network | Decentralized Bundler + DMN | Any token → settled in native token | Direct (settlement layer) |
Particle stands out by enabling gas payments in any token while settling transactions on its L1—creating a closed-loop economy where its native token accrues utility.
Impact on User and Developer Experience
For Developers
- Polygon & Optimism: Offer familiar tooling within their ecosystems. Ideal for teams building within CDK or OP Stack environments.
- NEAR: Provides powerful smart contract capabilities for cross-chain logic but demands deeper integration effort.
- Particle Network: Delivers a developer-first SDK that simplifies omnichain dApp development. Existing WaaS users can onboard instantly into the chain abstraction model.
For Users
- Current UX across most platforms still requires managing multiple wallets and pre-funding chains.
- Particle’s Universal Accounts offer the most seamless experience: one identity, one balance, cross-chain transactions with minimal delay.
- NEAR improves key management but stops short of full liquidity automation.
FAQ: Understanding Chain Abstraction
Q: What is chain abstraction?
A: Chain abstraction hides the complexity of interacting with multiple blockchains. It allows users to operate across chains with a single account, balance, and gas token—similar to how the internet works regardless of underlying hardware.
Q: How does account abstraction relate to chain abstraction?
A: Account abstraction (e.g., ERC-4337) enables smart contract wallets with advanced features. Chain abstraction builds on this by extending those capabilities across chains—unifying identity, liquidity, and execution.
Q: Can chain abstraction work across non-EVM chains?
A: Yes—projects like Particle Network support Bitcoin L2s and Solana, proving that chain abstraction can transcend consensus mechanisms and virtual machines.
Q: Is chain abstraction secure?
A: Security depends on implementation. Solutions using proven cryptography (like MPC) or established messaging protocols (like Hyperlane) reduce risk. Decentralized bundlers and verifiable relayers further enhance trustlessness.
Q: Will chain abstraction eliminate bridges?
A: Not eliminate—but render them invisible. Instead of manual bridging, swaps and transfers happen automatically under the hood during regular transactions.
Q: Which project offers the most complete chain abstraction today?
A: While no solution is fully mature, Particle Network presents the most comprehensive current model with Universal Accounts, shared liquidity, and heterogeneous chain support—all in testnet deployment.
