LAYERK Chain

Discover the future of blockchain with the LAYERK Chain and its revolutionary features. Step into a new era of token trading. Find out What is LAYERK Chain and How does it work

What is LayerK Chain?

LayerK Chain is a next-generation, application-specific blockchain built to harness the power of decentralization with maximum performance. Designed as a Layer 3 (L3) chain on top of Arbitrum one, it delivers high-speed, secure, and scalable solutions tailored to specific use cases.

How LayerK Works

L3 Architecture

LayerK Chain is built on Arbitrum One, operating as a Layer 3 chain that inherits Ethereum’s Proof-of-Stake (PoS) finality and Arbitrum's fraud-proof system. This design ensures rapid transaction processing while maintaining robust data integrity and trustlessness.

LayerK - Arbitrum One - Ethereum Interaction

Transaction & Fee Flow

1. User sends transaction on LayerK (L3)

   • Transactions are executed on LayerK.

   • Fee is paid in LYK

   • Transactions are rolled up into batches and sent to Arbitrum One (L2).

2. Arbitrum One receives batch from LayerK (L3 → L2)

   • Arbitrum processes and verifies the LayerK batch.

   • Arbitrum includes the L3 batch in its own state updates.

   • LayerK pays in arbETH to include its rolled-up data to be included in the Arbitrum as its settlement layer.

3. Arbitrum One posts rollup data to Ethereum (L2 → L1)

   • Arbitrum batches all recent txs (including from LayerK) and posts a rollup of calldata to Ethereum mainnet.

   • Fee is paid to Ethereum in ETH.

Example Flow Summary

Alice sends a tx on LayerK:

1. Tx executed on LayerK (fee in LayerK native token - $LYK).

2. LayerK rolls up txs periodically and submit them to Arbitrum (fee paid to Arbitrum in ETH).

3. Arbitrum batches LayerK data into its rollup and posts to Ethereum (fee in ETH).

Native Bridging

A built-in, bi-directional bridge to the rootchain enables seamless asset and data transfers, allowing LayerK to leverage rootchain security while expanding throughput and scalability.

EVM Compatibility

LayerK is fully EVM-compatible, allowing developers to deploy existing Ethereum smart contracts and dApps without significant code changes. This ensures a smooth migration path and access to the broader Ethereum ecosystem.

On-Chain Governance

Governance is handled transparently through on-chain voting through LayerK DAO platform, enabling token holders and community members to propose, debate, and implement protocol upgrades or changes.

Key Features

• App-Specific Customization Designed for tailored use cases, optimizing functionality for industry/dApp-specific needs.

• Seamless Interoperability Built-in bridge and Ethereum compatibility ensure smooth integration across networks.

• Scalable Infrastructure Layer 3 design significantly improves scalability, supporting faster and cheaper transactions.

• Decentralized Governance Community-led decision-making ensures transparent and inclusive protocol evolution.

• Enhanced Security The architecture incorporates layered consensus and inherited fraud-proof mechanisms, offering a secure environment for assets and data.

Upcoming Upgrade: LayerK + Pectra Features

LayerK is preparing for a major protocol upgrade that incorporates several key innovations from Ethereum’s Pectra upgrade suite. These enhancements aim to improve developer flexibility, dApp efficiency, and cryptographic performance.

Key Upgrade Features

• Native Account Abstraction (EIP-7702) Enables EOAs (Externally Owned Accounts) to execute code directly, allowing for:

  • Delegated transactions

  • Atomic batching (e.g., approve + spend)

  • Gas sponsorship via paymasters

  • Sub-key permissioning for finer access control

• BLS12-381 Precompiles (EIP-2537) (Preview) Precompiled cryptographic support for the BLS12-381 curve to accelerate:

  • zkSNARK verification

  • Cross-chain bridging

  • Randomness beacons

  • Vector commitments (Note: Included in this upgrade, activation coming in the next release)

• Extended Block-Hash Storage (EIP-2935) Adds on-chain access to ~27 hours of past block hashes via a dedicated system contract—enabling stateless clients and deep historical data queries.

• Improved Code Caching Updates to caching logic prevent the return of outdated contract code or size data for non-deployed contracts, ensuring real-time accuracy.

Upgrade Timeline

• Testnet: Full testing by end of August 2025

• Mainnet: Scheduled upgrade on September 16, 2025
