Porting Token Standards: Performance & Security — Forge College

Worried that token logic you wrote for Solidity will behave the same on Solana? This lesson explains why performance and security trade-offs change when you port token standards to Anchor/Rust and what concrete steps to take now. What you'll learn: You'll analyze how Solana's per-transaction compute budget and instruction batching reshape handler design, and how to identify hot execution paths in token flows. The lesson covers practical optimizations such as minimizing cross-account writes to avoid costly CPI and duplicate signing, shrinking on-chain storage to reduce rent and speed up execution, and reordering account mutations (the transfer, check, write pattern) to preserve atomicity while saving compute. You'll also implement security hardenings: authority revocation and recovery patterns, explicit precondition checks, and tests that assert safety properties. Finally, you will gather baseline compute and instruction counts, interpret Anchor test logs, run benchmarks to measure improvements, and document how each change affects future upgradeability and account-layout constraints. Who this is for: Intermediate Rust/Anchor developers who have already implemented transfer semantics, allowance-style mappings, and program-log event notifications. Familiarity with basic Solana accounts, CPIs, and Anchor test harnesses is expected. Key topics covered: - Solana compute budgeting and instruction batching implications for token handlers - Minimizing cross-account writes, CPI costs, and duplicate signers - Reducing storage footprint and rent impact via layout optimizations - Authority revocation, recovery primitives, and explicit precondition checks - Measuring compute/instruction counts and reading Anchor test logs - How optimizations and layout changes affect upgradeability and permissions Ready to apply these patterns to your codebase?
