Why Agglayer?
Our vision & benefits

Core Principles

User experience matters

Agglayer fixes a broken user experience. Users should experience a blockchain-based Internet like the Internet itself: easy to use, fun, with underlying technology abstracted in favor of the best UX.

Developer sovereignty

With emerging interop solutions, Agglayer offers developers something different: sovereignty and safety. Build wherever you want, build what you want, but don’t build in a silo.

Non-rent seeking

Agglayer does not extract tax or take a % of sequencer revenue from participating chains.

Unity

Agglayer sets a new standard for cross-chain interoperability. Connected chains interop safely in a unified environment. Any blockchain, regardless of consensus mechanism or architecture, can connect to Agglayer and benefit from shared liquidity and interoperability.

Chain agnosticism

Doesn’t matter the tech, Agglayer is designed to be as flexible as possible. That means it imposes no requirements on chains interested in interop. Every chain retains sovereignty.

Decentralized

When it decentralizes, no single entity will own or control Agglayer. It is built to be open, permissionless, and governed by cryptographic proofs, not trust.

Security First

Cryptographic proofs ensure safety for cross-chain transactions. No one chain can rug any other.

Collaboration

Agglayer is the result of contributions from multiple teams across the blockchain ecosystem

Core components
of Agglayer

Fungible tokens

Eliminates the need to wrap and unwrap tokens, providing a unified experience.

Creates security

No chain can withdraw more assets than have been deposited on the unified bridge

Lowers cost

Proofs across all chains are aggregated along with the pessimistic proof to amortize costs.

Lowers latency

Allows for interoperability at a latency lower than Ethereum finality.

Frequently
asked questions

What is Agglayer?

In a sentence: Agglayer is a neutral, cross-chain settlement layer that unifies liquidity, users, and state of aggregated chains, and posts finality to Ethereum. Agglayer solves blockchain fragmentation by enabling any chain to securely share liquidity, users, and state—and not only in the EVM ecosystem. The goal is to unify all web3, regardless of VM or execution environment

How is Agglayer different from bridging?

Bridging typically requires wrapped assets, trust assumptions, and a fragmented UX. Agglayer removes that friction — no wrapping, no multiple hops. Chains share state and liquidity natively, and users interact across chains as if they’re on one.

Is Agglayer a blockchain?

Not exactly. It’s a settlement and routing layer that connects blockchains. It doesn’t have its own VM or execution layer but enables coordination and shared security.

What does it cost to join Agglayer?

Right now, nothing — any chain can join without paying fees or modifying its architecture. Connected chains remain fully sovereign, with no obligation to pay additional tax (such as 15% of sequencer revenue). In the future, Agglayer will charge usage-based fees for premium features like fast interop and atomic execution. Fees can be paid in any token, giving chains full flexibility in how they participate. Core benefits are powered by staked POL, which captures the value created across the ecosystem.

How do I use Agglayer?

Agglayer is currently in development, with user-facing interfaces coming soon. Over time, you won’t need to think about using Agglayer at all — it will just work in the background. Much like you don’t know which Amazon server powers a website, Agglayer will quietly handle cross-chain execution, liquidity, and UX under the hood. The end goal: one-click, seamless interactions across chains, without the complexity.

How can I integrate with Agglayer?

Start by visiting the Agglayer docs to learn more and set up your environment. Developers can integrate through APIs or launch CDK chains that are natively connected to Agglayer via the Agglayer CDK. For direct support or partnership opportunities, feel free to reach out to our team — we’re here to help you get started.

Can other L1s and L2s join Agglayer?

Yes! The final state will be a multichain ecosystem, regardless of L1/L2 status, underlying security models, and VM. Expansion for support of a different variety of chains is forthcoming.

What does unified liquidity really mean?

Unified liquidity means you can access and interact with liquidity across chains using native assets, without wrapping or bridging. From Ethereum’s perspective, there’s a single canonical bridge — even though many chains are connected under the hood.

Do you need to build with CDK to connect to Agglayer?

No. Agglayer CDK chains have built-in support for Agglayer making it the easiest way to connect, but it’s not a requirement. Other chains can connect using alternative mechanisms that align with Agglayer’s settlement model.
