About Santiment Chain

What is Santiment Chain?

The Santiment Chain is an Ethereum OP Stack layer 2 blockchain built to provide an Infrastructure Layer for the Santiment Intelligence Network. The blockchain serves as the foundation for the protocol layer, where smart contracts implementing the platform’s core business logic are deployed. It ensures:

  • reliable and immutable execution of protocol logic,
  • open and accessible interaction for all participants — users, applications, and agents,
  • and acts as a trusted medium for interacting with data and reputation mechanisms of the platform.

Thus, Santiment Chain is essential to ensure that all operations on Santiment Intelligence Network — from submitting predictions to managing reputation — are carried out transparently, without intermediaries, and with full verifiability.

The Santiment Chain seamlessly integrates into the Optimism Superchain and Ethereum ecosystem. By leveraging the OP Stack's modular and open-source architecture, Santiment Chain inherits Ethereum's security and EVM equivalence, ensuring compatibility with existing Ethereum tools and smart contracts.

Its integration into the Superchain enables standardized interoperability, allowing for efficient cross-chain communication. This setup not only facilitates scalable and cost-effective transactions but also promotes a unified developer and user experience across the interconnected network of OP Chains.

Why use Santiment Chain?

Scaling Ethereum​

Santiment Chain is dedicated to scaling Ethereum with a powerful L2 delivering faster, cheaper transactions without compromising security.

EVM Equivalence​

Santiment Chain is EVM equivalent, meaning it runs smart contracts exactly as Ethereum does — no rewrites, no surprises. Developers can deploy existing contracts and use familiar tools like Hardhat, Foundry, and MetaMask with zero friction. It’s Ethereum, just faster and cheaper.

Built Into the Superchain​

Santiment Chain is part of the emerging Superchain — a unified network of interoperable L2s. This means users and developers can move assets, data, and apps across chains with minimal effort, without relying on slow or fragmented bridging solutions.

Lower Fees, Higher Throughput​

Thanks to rollup architecture, Santiment Chain dramatically reduces transaction costs while scaling throughput. Users benefit from a faster, more affordable experience, while Web3 applications can serve a broader audience without being bottlenecked by gas fees.

Ethereum-Grade Security​

Because Santiment Chain posts transactions and proofs to Ethereum L1, it inherits Ethereum’s security model. This ensures that even as you gain speed and scale, you don’t sacrifice trustlessness or decentralization.

What is Santiment Chain built on?

Santiment Chain is built on the OP Stack using Optimism’s open-source, modular rollup framework and is part of the Superchain — a network of closely aligned Layer 2 chains that share security, interoperability, and Ethereum-native infrastructure.
