Ink

Ink (INKCHAIN) is a Layer 2 (L2) blockchain developed by Kraken, designed to provide enhanced scalability and efficiency for decentralised finance (DeFi) applications. Built on the Optimism Superchain, Ink offers faster transaction speeds, significantly lower fees, and an improved user experience compared to the Ethereum mainnet.

InkChain leverages Optimistic Rollup technology, processing transactions off-chain while ensuring the security and decentralisation of Ethereum through periodic data settlements on Layer 1 (Ethereum). This reduces congestion on the Ethereum network while maintaining the same level of security and trust.

The platform also offers one-second block finality, with ongoing development aimed at achieving sub-second transaction speeds. This rapid processing time makes it ideal for high-frequency trading, lending platforms, and other real-time DeFi services.

Additionally, full Ethereum Virtual Machine (EVM) compatibility ensures that existing Solidity-based smart contracts can be deployed on InkChain without modification. This design makes it easy for developers familiar with the Ethereum ecosystem to build on Ink with minimal learning curve.

Ink (INKCHAIN) serves as a high-performance Layer 2 blockchain optimised for DeFi use cases and smart contract execution. Its primary uses include:

• Decentralised Finance (DeFi) Optimisation: By reducing gas fees and transaction times, Ink supports a wide range of DeFi services such as decentralised exchanges (DEXs), yield farming, staking, and lending protocols.
• Smart Contract Deployment: Developers can deploy Solidity-based smart contracts on InkChain seamlessly, as it maintains full EVM compatibility.
• Scalability for dApps: InkChain helps dApp developers scale their applications by moving transaction processing off the Ethereum mainnet, improving throughput while maintaining security.
• User Experience Enhancements: By integrating Kraken’s infrastructure, Ink enables a simplified user experience, from fiat-to-crypto conversions to DeFi engagement, making it more accessible for mainstream users and institutions.
• NFTs and Tokenisation: Ink also supports NFT minting and tokenisation use cases, expanding its utility beyond DeFi.

Ink (INKCHAIN) was developed by Kraken, a globally recognised cryptocurrency exchange founded in 2011, known for its focus on security, innovation, and expanding the blockchain ecosystem.

The development of Ink is led by Andrew Koller, a senior figure at Kraken, who has emphasised the project’s goal of providing a user-friendly blockchain environment with a focus on performance and accessibility. Kraken’s involvement in the project ensures a reliable and compliant platform suitable for both retail and institutional adoption.

Kraken chose to build on Optimism's Superchain due to its modular architecture, which allows for shared security, scalability, and interoperability among Layer 2 networks.
