Building from first principles with LimeChain

Problem

To attract developers, Hedera needs to offer seamless integration with existing EVM tools while preserving its native performance advantages. However, achieving this winning combination isn’t easy as it requires deep expertise across both Hedera and EVM ecosystems.

Solution

LimeChain has become a key development partner for Hedera, contributing major infrastructure such as the JSON-RPC Relay, Java SDK, and local testing environments, while helping author and implement essential EVM-compatibility HIPs. Their EVM expertise enables Hedera to connect with the broader web3 ecosystem while maintaining its strengths in speed, security, and predictable cost.

Hedera’s clear vision, open-mindedness, and commitment to innovation have been instrumental in shaping a more interconnected and efficient web3 ecosystem.

LimeChain & Hedera: Accelerating web3 infrastructure

As blockchain adoption accelerates, developers need reliable expertise to build scalable solutions. Over the past five years, LimeChain has evolved from an early Hedera collaborator into one of its most impactful technical partners, enhancing network interoperability and developer accessibility.

LimeChain’s contributions include the Hedera JSON-RPC Relay, Java SDK, and involvement in the Hiero open-source project under the Linux Foundation’s Decentralized Trust. Their work on numerous HIPs—such as introducing block compatibility and supporting ERC-standard calls—has been central to improving Hedera’s EVM equivalence and tooling.

A philosophy that fits Hedera

Founded in 2017, LimeChain grew methodically, focusing on strong engineering culture and blockchain-agnostic problem solving. Their expertise in EVM, decentralized application development, and advanced cryptography make them an ideal partner for Hedera’s interoperability goals.

From PoC to core network development

The partnership began with a proof-of-concept using HCS to sync data across Google Sheets and Microsoft 365—demonstrating Hedera’s value as a trusted coordination layer. Since then, LimeChain has become deeply embedded in Hedera’s technical roadmap, building infrastructure and shaping standards that improve developer experience and network integration.

Key infrastructure contributions

• Hedera SDK: Foundational tooling enabling developers to build across all Hedera services.
  
• JSON-RPC Relay: A critical bridge connecting Hedera to EVM tools, wallets, and ecosystems.
  
• Local Node Environment: A Hiero-based configuration enabling developers to test Hedera apps locally.
  
• HIP Contributions: Including block organization (HIP-415) and ERC-standard support (HIP-376), enabling compatibility with widely adopted web3 tooling.
  

Driving EVM compatibility & UX improvements

LimeChain has helped reconcile Hedera’s architecture with EVM expectations, ensuring compatibility while preserving Hedera’s performance advantages. Their work on account abstraction and onboarding flows supports better web3 user experiences, while their forward-looking focus on ZK technologies positions Hedera well for the next wave of blockchain innovation.

Why Hedera

LimeChain chose Hedera for its predictable fees, rapid settlement, robust token service, and efficient native features—all of which align with their solution-first philosophy. Hedera’s governance model, backed by global enterprises, adds credibility and stability attractive to enterprise clients.
