EVM Compatibility

While Sophon is EVM compatible and you can use familiar development tools from the Ethereum ecosystem, it provides two ways to deploy contracts:
  • Native zkEVM contracts (optimized for performance and lower gas costs)
  • Standard EVM contracts (through the EVM Bytecode Interpreter)

​
Key Benefits

  • EVM Compatibility: Most Ethereum smart contracts will work on Sophon
  • Familiar Development Tools: Use the same development tools like Hardhat and Foundry
  • Extended Functionality: Access to additional features like Paymasters
  • Dual Execution Models: Support for both zkEVM native contracts and EVM bytecode contracts
When developing for Sophon, consider the following:
  1. Test thoroughly on Sophon testnet before deploying to mainnet
  2. Be aware of gas model differences between Ethereum and Sophon
  3. Understand limitations in contract interactions between EVM and zkEVM contracts
  4. Take advantage of zkEVM-specific features like paymasters and account abstraction
