Across is an interoperability protocol using an intents-based architecture to enable fast, low-cost, and secure cross-chain transactions. Unlike traditional message-passing solutions, Across relies on relayers to fulfill user-defined outcomes instantly, with a separate settlement layer ensuring secure and verifiable fund transfers.
Blockscout is an open-source blockchain explorer designed for Ethereum Virtual Machine (EVM)-based networks. It provides users with a comprehensive interface to search transactions, view account balances, verify and interact with smart contracts, and engage with decentralized applications across various Ethereum networks, including mainnets, testnets, sidechains, and Layer 2 solutions. Unlike centralized, closed-source explorers, Blockscout offers transparency and flexibility, supporting hundreds of chains and rollups within the broader blockchain ecosystem, such as Ethereum, Cosmos, Polkadot, Avalanche, and Near.
Orbiter Finance is a decentralized cross-rollup bridge facilitating rapid, secure, and cost-effective transfers of Ethereum-native assets across various Layer 2 networks and Ethereum Virtual Machine (EVM)-compatible chains. By enabling seamless interoperability between these networks, it enhances the efficiency and scalability of decentralized applications (dApps) within the Ethereum ecosystem.
Layerswap provides a fast and cost-effective solution for transferring crypto assets across multiple networks and exchanges, reducing fees and transaction times while simplifying the bridging process. It operates without a formal governance structure or a native token. Layerswap has raised a total of $4 million across three funding rounds, with the latest being a $2.5 million seed investment on November 10, 2022.
Token Terminal, founded in 2020 and based in Helsinki, Finland, is a data analytics platform that standardizes financial and alternative data from blockchains and decentralized applications.
Brid.gg is a user-friendly platform that enables seamless asset transfers across Ethereum and Superchain networks, offering a secure and efficient transaction experience. It simplifies cross-chain transfers with a straightforward interface that supports Ethereum and Layer 2 solutions. Brid.gg operates without a formal governance structure, does not have a native token, and has no public funding records.
Foundation Missions are Optimism-funded initiatives designed to make measurable progress toward the Season 7 Intent, establishing interoperable Stage 1 chains handling $250M in cross-chain asset transfers per month.
The Retro Funding: Dev Tooling program rewards open-source toolchain software that supports onchain application development on the Superchain, with a budget of up to 8M OP and monthly rewards from March to July 2025.
OP Mainnet, previously known as Optimism, is a Layer 2 scaling solution built on top of Ethereum. It utilizes optimistic rollups to provide faster and cheaper transactions while maintaining the security of the Ethereum mainnet.
Ink is a Layer 2 blockchain built by Kraken powered by the OP Stack. It connects Kraken’s 10+ million users to decentralized finance (DeFi), offering easy access to DEXs, lending, and yield protocols. By joining the Superchain, Inkchain combines Ethereum’s security with Layer 2 scalability for a streamlined DeFi experience.
Unichain is an L2 purpose-built for DeFi, exclusively on the OP Stack. Unichain is part of the Superchain’s path to interoperability, and will support ERC20s that are Superchain interop compatible. Uniswap Labs is also working with Flashbots to develop a new TEE-based block builder that reduces Unichain confirmation times from 1 second to 250 milliseconds.
Soneium is a Layer 2 blockchain developed by Sony Block Solutions Labs, a joint venture between Sony Group and Startale. Designed to bridge Web2 and Web3, Soneium aims to create a versatile, developer-friendly ecosystem that empowers creativity and innovation. It provides a scalable, accessible platform for developers, creators, and communities, enabling them to build and deploy applications that blend entertainment, gaming, finance, and more.
