Dual Virtual Machine Support - On Phase 1

Ethereum Virtual Machine (EVM) Integration Arichain provides full EVM compatibility, ensuring existing Ethereum applications can migrate seamlessly:

• Complete Protocol Compatibility: Support for all Ethereum Improvement Proposals (EIPs) including the latest protocol upgrades

• Familiar Developer Tools: Native integration with MetaMask, Hardhat, Truffle, Remix, and other Ethereum development tools

• Existing dApp Migration: Ethereum dApps can deploy on Arichain without code modifications

• JSON-RPC API: Full support for standard Ethereum APIs (eth_, net_, web3_*)

Solana Virtual Machine (SVM) Integration Arichain maintains full compatibility with Solana's high-performance execution environment:

• Account Model Support: Native implementation of Solana's account-based architecture

• BPF Program Execution: Full Berkeley Packet Filter (BPF) program support for maximum performance

• Solana Tooling: Compatible with Solana CLI, Anchor framework, and existing development tools

• Program Derived Addresses: Native support for PDAs and cross-program invocations

Single Wallet Multi-VM Architecture

Unified Wallet Experience Arichain provides a seamless user experience through a single wallet that can interact with both VM environments:

• Single Private Key: One private key pair works across all supported virtual machines

• VM-Specific Calls: Users specify target VM through transaction flags or parameters

• Consistent Address Format: Unified address format with VM-specific derivation

• Native Token Access: Same wallet can hold and manage tokens from both EVM and SVM ecosystems

VM Selection Mechanism Transactions are routed to the appropriate VM based on explicit user selection:

// EVM transaction with VM flag
const evmTransaction = {
  to: contractAddress,
  data: contractData,
  targetVM: 'EVM',
  gasLimit: 21000
};

// SVM transaction with VM flag
const svmTransaction = {
  instructions: [instruction],
  targetVM: 'SVM',
  computeLimit: 200000
};

Execution Performance

The Multi-VM architecture is designed for optimal performance across both execution environments:

Parallel Execution

• EVM and SVM transactions can execute simultaneously when there are no state conflicts

• Intelligent dependency analysis ensures correct ordering of interdependent transactions

• Resource isolation prevents one VM from impacting the other's performance

Optimized State Management

• Shared global state database enables efficient cross-VM data access

• Merkle trie optimization for fast state verification

• Atomic commitment protocols ensure consistency across all VMs

Real-World Benefits

For Developers

• Use familiar tools and languages from both ecosystems

• No need to learn new programming paradigms or tools

• Access to the combined liquidity and user base of both ecosystems

For Users

• Single wallet works across all applications regardless of underlying VM

• Consistent user experience across different dApp types

• Lower transaction costs through optimized execution paths

For dApp Projects

• Access to broader developer talent pool (both Ethereum and Solana developers)

• Ability to optimize different parts of applications for specific VM strengths

• Reduced technical debt from maintaining multiple chain deployments
