Kraken Launches ‘Ink’ Layer-2 Network on Optimism Stack, Joining Ethereum’s Expanding Superchain

Kraken, one of the world’s largest cryptocurrency exchanges, has officially announced the launch of its own Ethereum layer-2 network called Ink, built on the Optimism OP Stack. The move positions the exchange as a direct competitor to Coinbase’s Base network and marks another major milestone in the ongoing expansion of Ethereum’s modular blockchain ecosystem.

TL;DR

• Kraken partners with Optimism to launch Ink, a new Ethereum layer-2 network built on the OP Stack
• Ink joins Coinbase’s Base as a major exchange-backed L2 on the Optimism Superchain
• The network is expected to become operational in early 2025
• The move underscores the growing trend of centralized exchanges building decentralized infrastructure
• Ethereum’s layer-2 ecosystem continues to attract institutional players seeking scalability

Kraken’s Strategic Leap Into Layer-2 Territory

The announcement, made on October 24, 2024, reveals that Kraken has selected Optimism’s technology framework to construct its layer-2 solution. The OP Stack serves as a modular, open-source framework that enables developers to build their own blockchains with enhanced scalability and efficiency. By leveraging this technology, Kraken aims to offer users faster transactions and lower fees while maintaining the security guarantees of the Ethereum mainnet.

Kraken’s entry into the layer-2 space represents a significant strategic shift for the exchange. While primarily known as a centralized trading platform, the company has been steadily expanding its technological footprint across the decentralized ecosystem. The Ink network positions Kraken competitively alongside Coinbase, which launched its own OP Stack-based Base network in August 2023.

The OP Stack and the Superchain Vision

Optimism’s OP Stack has emerged as one of the most widely adopted frameworks for building layer-2 networks on Ethereum. The technology powers a growing number of chains that collectively form the “Superchain” — an interconnected network of L2s that share security, interoperability, and a common technological foundation.

By joining the Superchain, Kraken’s Ink gains access to cross-chain composability with other OP Stack networks, including Base, Zora, and Mode. This interoperability enables users to seamlessly move assets and interact with decentralized applications across multiple chains without relying on bridging solutions that introduce additional security risks.

The Superchain approach reflects Ethereum’s broader roadmap toward a rollup-centric future, where the base layer serves primarily as a data availability and settlement layer while execution happens on layer-2 networks. Kraken’s adoption of this model signals strong institutional validation of Ethereum’s scaling strategy.

Exchange-Backed L2s Reshape the Competitive Landscape

The trend of centralized exchanges building their own layer-2 networks has accelerated throughout 2024. Coinbase’s Base has demonstrated the potential of this approach, quickly becoming one of the most active layer-2 networks by transaction volume and total value locked. With Kraken now entering the space, the competitive dynamics within Ethereum’s L2 ecosystem are shifting significantly.

For exchanges, launching a proprietary layer-2 network offers several strategic advantages. It creates a direct pipeline for onboarding users into decentralized applications, generates revenue through sequencer fees, and strengthens the exchange’s position within the broader Web3 ecosystem. Additionally, these networks can serve as incubators for new DeFi protocols and applications that drive user engagement.

What This Means for Ethereum’s Ecosystem

Kraken’s decision to build on the OP Stack rather than pursuing an independent chain architecture reinforces Ethereum’s dominance as the settlement layer for the crypto industry. The move also validates the modular blockchain thesis, where specialized layers handle different aspects of blockchain operations — from execution to data availability to settlement.

As more major players adopt layer-2 solutions, Ethereum’s network effects continue to strengthen. The growing number of OP Stack chains also contributes to network effects within the Superchain itself, as shared infrastructure and interoperability create compounding advantages for all participants.

Why This Matters

Kraken’s launch of Ink represents a pivotal moment in the maturation of Ethereum’s layer-2 ecosystem. When one of the world’s top exchanges by trading volume commits to building on a specific scaling framework, it sends a powerful signal about the direction of blockchain infrastructure. The OP Stack’s growing dominance as the preferred framework for institutional-grade L2 networks suggests that Ethereum’s modular approach to scaling is winning the battle for developer and enterprise mindshare. For users, the proliferation of exchange-backed L2s means more options for fast, low-cost transactions with the security backing of major financial institutions. As Ink prepares to go live in 2025, all eyes will be on whether it can match or surpass the momentum that Base has built over the past year.
