Overview
Ink is a Layer 2 blockchain built on Optimism’s OP Stack, developed by Kraken to enhance decentralized finance (DeFi) accessibility and scalability. Launched on December 18, 2024, Ink is integrated into the Optimism Superchain, providing seamless interoperability and robust performance across the Ethereum ecosystem¹.
Technical Architecture
Ink utilizes the OP Stack, a modular and open-source framework developed by Optimism for scalable Ethereum-based blockchains. The OP Stack ensures Ethereum Virtual Machine (EVM) equivalence, allowing developers to deploy Solidity-based smart contracts without requiring modifications².
Network Specifications

Performance and Scalability
Ink offers one-second block times at launch, with plans to reduce this to sub-second intervals. This high-speed performance enhances transaction throughput and improves dApp usability, making Ink a compelling choice for DeFi projects².
Security and Trust
Security is a cornerstone of Ink’s infrastructure. The platform benefits from Kraken’s extensive expertise in digital asset security, alongside sequencer-level safeguards against malicious activities. This ensures user trust and network reliability³.
Tokenomics
Ink utilizes ETH as its native currency for gas fees and other on-chain activities. By aligning with Ethereum’s economic model, the chain simplifies onboarding for users and developers already familiar with Ethereum’s framework. The use of ETH also ensures direct compatibility with Ethereum-based tools and dApps².
Ecosystem and Use Cases
Ink serves as a launchpad for DeFi protocols, fostering the growth of innovative applications. As part of the Optimism Superchain, Ink facilitates seamless asset transfer and interaction between participating chains. Key early integrations include the deployment of Tether’s cross-chain stablecoin, USDT0, on the Ink network, enhancing liquidity and ecosystem utility⁴.
