Solidity to Rust/Anchor: Guided Translations of Core Patterns — Forge College

Why translate common Solidity patterns to Rust/Anchor now? As projects migrate from EVM chains to Solana, having concise, catalog-ready translations lets teams preserve security and intent while adopting Solana's account model and Anchor conventions.

What you'll learn
This lesson walks through three concrete, annotated translations: an Ownable/access-control contract, a mapping(address =⟩ uint256) state pattern, and Solidity events plus custom errors converted into Anchor events and Rust Result-based error types. You will see side-by-side Solidity and idiomatic Rust/Anchor snippets with 2–3 sentence rationales that cite specific mapping rules (ownership =⟩ explicit owner accounts; mappings =⟩ PDA or account-backed storage; events =⟩ Anchor events; errors =⟩ Rust enums). The lesson shows serialization choices (Borsh vs manual), PDA design tradeoffs for storage density and compute, and how to validate examples with cargo build or anchor build.

Who this is for
Intermediate developers who already know Solidity and basic Rust/Anchor concepts. Ideal for engineers migrating smart contracts from EVM to Solana who need reproducible translation patterns.

Key topics covered
- Ownable/access-control: owner accounts, #[access_control]-style guards, and manual checks
- Mapping to storage: mapping(address =⟩ uint256) translated to PDA-backed accounts and account layouts
- Events and errors: Solidity events and custom errors into Anchor events and Rust enum Result types
- Serialization and storage tradeoffs: Borsh, packing, and compute/gas analogs on Solana
- Side-by-side code entries and 2–3 sentence rationales per pattern
- Local validation: cargo build and anchor build to type-check translations
