Blockchain.com has officially integrated support to Optimism, CELO and Arbitrum in a considerable step towards the multichain future. The decision also establishes Blockchain.com as one of the best wallets and exchange platforms enabling users to transact through third-generation blockchain systems not only Bitcoin and Ethereum.
This kind of integration brings even more potentially better, quicker, and more convenient ways of managing one digital assets as adoption of crypto makes a breakthrough in 2025. To simplify this, here is what it means to you, and why it is a big deal.
Why This Integration Matters
The blockchain world is no longer dominates by just Ethereum or Bitcoins. As network get congested and fees rise, the demand for scalable alternatived and Layer 2 solutions has surged. Enter Optimism, CELO, and Arbitrum — networks designed to solve Ethereum’s limitations and enhance user experience.
By bringing these chains into its ecosystem, Blockchain.com is embracing the multi-chain future — one where users can choose the chain that best suits their needs, from low fees to mobile-first financial tools.
Network Overviews
Optimism
Optimism is one of the leading Layer 2 solutions on Ethereum, leveraging Optimistic Rollups to provide faster and cheaper transactions. It’s the foundation for projects like Velodrome, Lyra, and many others in the DeFi and GameFi space.
As of 2025, the OP Stack — Optimism’s modular software — is now powering not only its own network but also other Layer 2s such as Base (by Coinbase) and Mode Network, making it a backbone of Ethereum scaling.
CELO
Originally a stand alone Layer 1 blockchain, with mobile-first access and real-world payments in mind, CELO has suffered a significant shift.
Early in 2025, CELO will go onto Ethereum Layer 2 based on restaking architecture by EigenLayer, significantly enhancing compatibility with the Ethereum ecosystem without changing its financial inclusion and environmental friendliness mission. CELO is still negative carbon emissions, and it fulfills its regenerative finance (ReFi) role.
Arbitrum
Arbitrum is a powerhouse in the Ethereum Layer 2 space, best known for its DeFi dominance and the governance strength of its ARB token. With billions in total value locked and a growing network of protocols, Arbitrum is the most widely used L2 solution today and Improve Crypto Accessibility.
Its Orbit framework, introduced in 2024, allows developers to spin up custom Layer 3 chains (appchains) on top of Arbitrum, opening new frontiers for scaling and modular design.
