Description
OP Mainnet provides Layer 2 scaling for Ethereum through optimistic rollup technology, enabling faster and cheaper transactions while maintaining Ethereum security. The network processes transactions off-chain and submits batched data to Ethereum for settlement.Category: L2
OP Stack
Project Links
Description
OP Stack is an open-source software stack for building Layer 2 blockchains and rollups that settle to Ethereum. Developers use OP Stack components to launch custom chains with configurable execution layers, sequencers, and data availability options while inheriting Ethereum security through fraud-proof verification. Chains built on OP Stack natively interoperate within the Superchain ecosystem through shared messaging and bridge protocols.Category: Developer Tooling
Superchain
Project Links
Description
Superchain is an interoperable network of OP Stack-based Layer 2 blockchains that share a common security model, governance framework, and cross-chain messaging protocols. Member chains (including OP Mainnet, Base, Worldchain, and others) settle to Ethereum and interoperate natively through standardized bridge contracts. The framework lets applications operate across multiple L2s as if they were a single chain.Category: Cross-chain Infrastructure
OP Enterprise
Project Links
Description
OP Enterprise is a managed blockchain infrastructure service for organizations building on the OP Stack. It provides tiered deployment options ranging from permissionless access on OP Mainnet to fully managed custom chains with 24/7 monitoring, incident response, and SLA-backed uptime guarantees. The service bundles lifecycle management, compliance tooling, pre-vetted infrastructure partnerships, and dedicated support to consolidate vendor management for enterprise teams.Category: Blockchain-as-a-Service (BaaS)
Actions SDK
Project Links
Description
Actions SDK is a developer toolkit that allows applications to embed DeFi lending, borrowing, and token swap features through a single integration. It connects to established lending and exchange protocols, handles wallet interactions through supported providers, and offers configurable controls for asset allowlists, chain restrictions, and custody models. The SDK targets OP Stack chains and Ethereum mainnet, enabling non-blockchain-native teams to ship DeFi functionality without building separate protocol integrations.Category: Developer Tooling
