AltLayer (ALT): What Is It? Definition & Explanation
AltLayer (ALT) is an Ethereum L2 infrastructure protocol that offers rollups-as-a-service (RaaS), secured by EigenLayer restaking. Supporting multiple rollup frameworks including OP Stack, Arbitrum Orbit, and ZK Stack, AltLayer makes it easy for projects to launch their own application chains.

AltLayer is a Rollup-as-a-Service (RaaS) protocol founded in 2021 that entered the token market via Binance Launchpool in January 2024. The project's core innovation is using EigenLayer's restaking mechanism to deliver higher security, decentralization, and faster finality for rollups.
What Is AltLayer? The Restaked Rollup Concept
Traditional rollups inherit most of their security from Ethereum. AltLayer's "Restaked Rollup" approach takes this a step further: restaked ETH via EigenLayer is used to strengthen rollup validation, delivering three core properties:
- Enhanced security (VITAL): EigenLayer AVS for verification and state monitoring
- Fast finality (MACH): Much shorter wait times instead of the 7-day window on optimistic rollups
- Decentralized sequencing (SQUAD): A distributed structure not dependent on a single sequencer
Supported Rollup Frameworks
| Framework | Description |
|---|---|
| OP Stack | Optimism-based rollups (Superchain compatible) |
| Arbitrum Orbit | Arbitrum's application chain framework |
| ZK Stack | ZKsync-based ZK rollups |
| Polygon CDK | Polygon's ZK rollup development kit |
Any of EigenDA, Celestia, Avail, or NEAR DA can be used for data availability — a flexibility that is a key part of the project's layered architecture approach.

ALT Token and Ecosystem
ALT's total supply is fixed at 10 billion. The token is used for governance voting in the protocol, staking for AVS (Actively Validated Service) operators, and as rollup security collateral.
Since 2025, AltLayer has been investing not only in RaaS but also in AI agent infrastructure: the Autonome and Wizard platforms provide infrastructure for AI agents running on-chain.
Ecosystem partnerships: EigenLayer, Celestia, Avail, Connext, Celer, Hyperlane, Transak.
Risks and Considerations
- Crowded RaaS market: Competitors like Conduit, Caldera, Gelato, and Alchemy Superchain offer similar services. Differentiation is critical.
- Value capture uncertainty: ALT's value capture mechanism beyond governance has yet to mature.
COINOTAG Perspective
AltLayer is an infrastructure protocol sitting at the heart of Ethereum's rollup-centric scaling vision. EigenLayer integration provides strong technical differentiation versus traditional RaaS solutions. The 2025 AI agent pivot added an extra narrative layer to the project. The decisive question for mid-term valuation: how many projects are genuinely choosing AltLayer, and what does active user count look like on those chains?
Frequently Asked Questions
What is AltLayer (ALT)?
AltLayer is an Ethereum L2 infrastructure protocol offering rollups-as-a-service (RaaS) secured by EigenLayer restaking. It supports OP Stack, Arbitrum Orbit, ZK Stack, and Polygon CDK rollup frameworks.
What does 'Restaked Rollup' mean?
A Restaked Rollup uses restaked ETH via EigenLayer to strengthen rollup validation. This approach provides three AVS services: VITAL (enhanced security), MACH (fast finality), and SQUAD (decentralized sequencing).
What is the ALT token used for?
ALT has three primary functions: (1) governance voting in the protocol; (2) staking for AVS (Actively Validated Service) operators; (3) rollup security collateral. Total supply is 10 billion ALT.
Who are AltLayer's competitors?
In the RaaS market, Conduit, Caldera, Gelato, and Alchemy Superchain are the main rivals. AltLayer's differentiators are its EigenLayer AVS integration and multi-framework (OP Stack + Arbitrum Orbit + ZK Stack) support.
