Thinking of moving an Ethereum contract to Solana? Porting smart contracts is a strategic decision that changes security assumptions, upgradeability, costs, and user experience — and getting it wrong can break both functionality and economic intent. What you'll learn This lesson explains the core motivations and tradeoffs behind porting an EVM contract to Solana and gives a practical framework to plan a migration. You will learn three primary business and technical drivers that typically motivate a port (performance and throughput, cost and UX, and access to Solana-native composability) and how each should shape migration priorities. The lesson shows how to classify high-level migration risks as behavioral, structural, or dependency risks, and how those categories map to testing and mitigation. You will produce a minimal contract-surface inventory (external entry points, persistent state items, cross-contract integrations), audit an EVM dependency and library graph to flag items that need replacement or redesign, and follow a short migration checklist that sequences discovery, mapping, prototype porting, testing, and risk mitigation. A function-level walkthrough uses a typical ERC-20 transfer to illustrate differences in entry points, storage layout, event/log mapping, return semantics, and upgrade patterns (for example, delegatecall-based upgradeability versus Solana program immutability or distinct upgrade paths). Who this is for Intermediate smart-contract engineers and auditors who already know Solidity, common EVM vulnerabilities (reentrancy, unchecked math, delegatecall patterns), and basic security audit artifacts like entry-point maps and state diagrams. Key topics covered - Business and technical motivations for porting (performance, costs, composability) - Classification of migration risks: behavioral, structural, dependency - Minimal contract-surface inventory: entry points, state, integrations - Dependency and library audit: replace, redesign, or reimplement - Function-level porting example: Solidity transfer to Solana (Anchor) mapping - Practical migration planning checklist: discovery → prototype → test → mitigate Ready to apply this to a real project?
