Introduction to OPN Chain
Overview
OPN Chain represents a new approach to EVM-compatible blockchain technology. Our platform is purpose-built for developers who need the familiarity of Ethereum with significantly improved performance and cost efficiency. We've created a blockchain that delivers enterprise-grade reliability while maintaining complete compatibility with the Ethereum ecosystem.
Key Features
Full EVM Compatibility
Deploy your existing Ethereum smart contracts without any modifications. OPN Chain supports:
Solidity versions up to 0.8.30
All standard EVM opcodes
Ethereum JSON-RPC API
Your favorite development tools
Pectra Support
Stay on the cutting edge with support for Ethereum's latest Pectra upgrade, including:
EIP-7702: Set EOA account code for advanced account abstraction
Enhanced opcodes for more efficient smart contract execution
Gas optimizations that reduce costs for complex operations
Latest security improvements from Ethereum mainnet
High Performance
~1 second block times: Near-instant transaction confirmations
Fast finality: Transactions are final within seconds
High throughput: Handle thousands of transactions per second
Reliable uptime: Built on proven consensus mechanisms
Low Costs
7 Gwei minimum gas price: Among the lowest in the EVM ecosystem
Predictable fees: No gas price spikes during high usage
Efficient operations: Optimized for cost-effective smart contract execution

DeFi Applications
Build decentralized exchanges, lending protocols, yield farms, and more with low transaction costs and fast confirmations.
Gaming & NFTs
Create blockchain games and NFT marketplaces that can handle high transaction volumes without breaking the bank.
Enterprise Solutions
Deploy private or consortium chains using OPN technology for supply chain, identity, and other enterprise use cases.
Web3 Infrastructure
Run nodes, build indexers, create oracles, and provide other infrastructure services on a reliable, high-performance network.
Tokenization
Transform real-world assets into digital tokens - from real estate and commodities to intellectual property and financial instruments. OPN Chain's low costs and high speed make it ideal for tokenizing assets at scale.
DeFAI (Decentralized Finance + AI)
Leverage the intersection of DeFi and AI with smart contracts that can interact with AI models, automated trading strategies, and intelligent financial protocols. Build the next generation of autonomous financial systems.
DePIN (Decentralized Physical Infrastructure)
Deploy decentralized networks for physical infrastructure including IoT devices, sensors, computing resources, and data networks. OPN Chain's efficiency enables cost-effective coordination of distributed hardware networks.
