Ink from Kraken and Base from Coinbase are two Ethereum Layer 2 projects built using OP Stack technology from the Optimism Superchain. Both are designed to onboard retail users from centralized exchanges (CEX) into the DeFi ecosystem with lower fees, faster transactions, and a more seamless user experience. As of April 2026, both continue to attract attention due to scalability, integration with their parent platforms, and the development of their respective ecosystems.

Key Similarities

Underlying Technology:
Both use OP Stack, making them compatible with the Ethereum Virtual Machine (EVM) and using ETH as the gas token.

Primary Objective:
To bridge millions of CEX users into on-chain DeFi without high complexity.

Token Status:
As of now, neither has fully launched a native token for governance or primary utility (although there are discussions and signals regarding potential future tokens).

Backers:
Supported by major exchanges with significant user bases, Kraken for Ink and Coinbase for Base.

Key Differences

1. Scale and Performance Metrics

Base is currently one of the largest Layer 2s in the Ethereum ecosystem. Its Total Value Locked (TVL) stands at around $7.8 billion or higher in early 2026, with a significant share of total Ethereum L2 TVL, roughly 40–60% across certain revenue and activity metrics. Daily active addresses often reach hundreds of thousands, approaching 400,000+, and it dominates in transaction and DEX volume among rollups.

Ink, on the other hand, has shown rapid growth since late 2025. Its TVL has surpassed $500 million and stabilized in the hundreds of millions. This growth is driven by early DeFi activity, though its scale remains smaller compared to Base. Ink reflects an early expansion phase with dynamic growth potential.

2. Ecosystem Focus and Applications

Ink:
More oriented toward pure DeFi. Its ecosystem highlights applications such as Tydro (a lending protocol similar to Aave), Nado (a DEX featuring order books and perpetuals), as well as a meme coin launcher similar to pump.fun. It also includes simple engagement features like daily check-in streaks. The approach is designed to bring Kraken users directly into on-chain yield and trading activities.

Base:
More mature and diverse. Its ecosystem spans DeFi, SocialFi, NFTs, meme coins, and many established third-party protocols. Direct integration with Coinbase Wallet simplifies bridging and fiat on-ramp onboarding, making it suitable for users seeking a comprehensive experience with deep liquidity.

3. Development Strategy and Future Potential

Base has established itself as a leading Layer 2 with strong sequencer revenue and dominance in on-chain activity and volume. Backing from Coinbase provides broad and stable user distribution.

Ink leverages Kraken’s user base of approximately 10 million to drive DeFi adoption. Its focus on early-stage DeFi applications creates opportunities for early participants to contribute to ecosystem growth.

Discussions around potential tokens and user rewards remain ongoing in both projects, with an emphasis on organic activity and genuine usage.

Conclusion

Base offers large scale, high liquidity, and a mature ecosystem, making it suitable for users who prioritize stability and high volume.

Ink, meanwhile, presents opportunities at a more dynamic growth stage with a sharper DeFi focus, which may appeal to those seeking innovation in an emerging chain.

The choice between the two depends on preference: whether you favor an established ecosystem with a massive user base like Base, or a fast-growing DeFi-focused chain like Ink. As with any blockchain project, it is recommended to conduct your own research (DYOR), monitor official updates, and consider the inherent risks of the crypto market.

Both projects represent different approaches by major exchanges to expand access to DeFi. Their future development will largely depend on user adoption, application innovation, and the evolution of the Optimism Superchain ecosystem as a whole.
