The Web3 ecosystem in 2025 is defined by its relentless push for scalability, modularity, and seamless user experience.

At the heart of this transformation are Rollup-as-a-Service (RaaS) platforms, which provide turnkey solutions that let projects launch custom Layer 2 and Layer 3 chains without the headaches of deep protocol engineering.

1. Caldera: The Modular Powerhouse

Caldera has quickly become a cornerstone for Web3 teams seeking reliability, flexibility, and composability.

  • Multi-Framework Support: Caldera supports OP Stack, Arbitrum Orbit, Polygon CDK, and zkSync, making it a versatile choice for a wide range of Web3 applications.
  • Metalayer Interoperability: Its Metalayer protocol connects all Caldera-based rollups, enabling shared liquidity and intent-based bridging, crucial for cross-chain DeFi, NFT, and social dApps.
  • Token Launch & Governance: The recent launch of the ERA token brings omnichain gas payments, validator staking, and decentralised governance to the ecosystem.
  • Reliability: With the majority of uptime and robust technical support, Caldera is trusted by over 50 rollups.

Caldera’s modularity and ecosystem-first approach make it a top pick for Web3 projects that demand both flexibility and future-proof infrastructure.

2. Conduit: The No-Code Web3 Enabler

Conduit is about making rollup deployment as simple and accessible as possible.

  • Self-Service Deployment: Launch mainnet or testnet rollups in minutes, no code or sales calls required.
  • Market Share: Powers more than 30% of mainnet rollups, serving DeFi, DAOs, NFT marketplaces, and consumer apps.
  • Comprehensive Tooling: Offers high-availability sequencers, customizable configurations, native gas tokens, decentralised sequencing, and a suite of integrations for account abstraction, payments, and analytics.
  • Transparent Pricing: Clear, upfront pricing and 99.999% SLAs provide peace of mind for Web3 teams.

Conduit’s zero-code, all-in-one approach is ideal for Web3 builders who want to focus on product, not DevOps.

3. Gelato: Automation Meets Web3 Infrastructure

Gelato brings its automation to the RaaS space, offering a deeply integrated Web3 development environment.

  • Turnkey L2 Deployment: Supports Optimism OP Stack, Arbitrum, and Polygon zkEVM, allowing rapid launch of production-ready L2s.
  • Web3 Middleware Integration: Native support for automation, off-chain data, account abstraction, oracles, bridges, and data indexers.
  • High Availability: Explorer-as-a-service for custom branding and transparency.
  • Customisation: Developers can tailor rollups for DeFi, social, gaming, and enterprise use cases, with built-in revenue dashboards and cost optimisation.

Gelato’s automation-first, middleware-rich platform is a standout for Web3 projects needing sophisticated, scalable infrastructure.

4. AltLayer: Restaked Rollups and Interoperability

AltLayer is pushing the boundaries of modularity and security in the RaaS.

  • Restaked Rollups: Leverages EigenLayer’s restaking to provide crypto-economic security across OP Stack, Arbitrum Orbit, Polygon CDK, and ZK Stack.
  • Rapid Customisation: Developers can spin up interoperable, decentralised rollups in minutes, with support for both optimistic and ZK rollups.
  • AVS-as-a-Service: Offers rapid deployment and management of Actively Validated Services (AVS) for the EigenLayer ecosystem.
  • Ecosystem Partnerships: Backed by Binance Labs and powering high-profile projects like T-Rex Chain and B3’s TGE, AltLayer is at the centre of Web3’s expansion.

AltLayer’s focus on security, interoperability, and developer accessibility makes it a compelling choice for ambitious Web3 projects.

5. Saga: Infinite Scalability for Web3

Saga is reimagining scalability and interoperability for the next generation of decentralised applications.

  • Chainlets: Developers can launch VM-agnostic, parallelised, and interoperable dedicated chains (“Chainlets”) with a click, each inheriting security from the Saga mainnet.
  • Liquidity Integration Layer: Saga’s LIL connects all Chainlets and external ecosystems, solving liquidity fragmentation and enabling seamless asset movement.
  • Flexible Monetisation: Chainlet fees are set by daily validator auctions, allowing for cost-effective and customizable monetisation models.
  • Ecosystem Growth: In under two years, Saga has powered 350+ projects across DeFi, NFTs, entertainment, and more.

Saga’s infinite horizontal scalability and liquidity-centric model position it as a foundational layer for the Web3 multiverse.

The 2025 RaaS

RaaS platforms are democratizing access to scalable, customizable blockspace, enabling projects of all sizes to launch and iterate quickly.

The shift toward modular, interoperable infrastructure is breaking down silos and accelerating innovation across DeFi, NFTs, social, and beyond.
