Multi-Chain Node Infrastructure & RPC Tools

LimeChain provides production-ready node infrastructure and RPC tooling across Hedera, Polkadot, and NEAR blockchain ecosystems, enabling developers to build, test, and deploy applications with enhanced compatibility and network diversity.

Product Overview

LimeChain's node infrastructure suite includes JSON RPC relays, local development environments, alternative client implementations, and comprehensive API libraries. These tools bridge different blockchain ecosystems, provide local testing capabilities, and contribute to network resilience through client diversity. Each product is designed to lower barriers for developers entering new blockchain ecosystems while maintaining production-grade reliability.

Key Products

Hedera JSON RPC Relay - Implementation of Ethereum JSON RPC APIs for Hedera, enabling Ethereum developers to deploy and interact with smart contracts on Hedera using familiar Ethereum tooling like MetaMask, Hardhat, and Truffle. This relay provides seamless compatibility between the Ethereum development ecosystem and the Hedera network.

Hedera Local Node - Complete local Hedera network environment for development and testing, including consensus nodes, mirror nodes, and all necessary services. Developers can test Hedera applications locally without using the public testnet, significantly improving development velocity and reducing costs.

Fruzhin - Java implementation of the Polkadot Host, providing an alternative client for the Polkadot network. This contributes to client diversity and network resilience while enabling Java developers to run Polkadot nodes and participate in network consensus. Fruzhin serves as an important backup implementation enhancing protocol security.

NEAR JavaScript API - Official JavaScript/TypeScript library for comprehensive NEAR blockchain interaction. LimeChain maintains and contributes to this SDK, providing developers with tools for wallet integration, smart contract interactions, account management, and transaction handling.

Use Cases

Developers use these tools to build cross-chain applications, test blockchain implementations locally, run alternative node clients for network participation, and integrate blockchain functionality into JavaScript/TypeScript applications. The infrastructure supports everything from initial prototyping to production deployment across multiple major blockchain ecosystems.
