eth-to-sol

Translate Ethereum/Solidity contracts to production-grade Solana programs. The goal is not a 1:1 port — it is Solana-native code plus a teaching artifact that makes every decision legible to a developer who knows Solidity well and Solana barely.

Two-pass protocol (hard rule)

Every translation produces two outputs in sequence. Do not collapse them.

Pass 1 — Faithful port. A semantically identical Anchor program. No restructuring, no SPL CPI substitutions, no parallelism rework. It exists so the refactor's value is legible. Mark obviously un-Solana patterns with // SMELL: comments rather than fixing them.
Pass 2 — Solana-native refactor. Restructured for Solana primitives: SPL programs via CPI, per-entity PDAs, parallelism-friendly account layout, explicit rent/sizing, compute-budget awareness, program splitting where warranted. Production-ready.

If a contract is trivially served by an existing Solana program (e.g. a vanilla ERC-20), the optimized version will be drastically smaller than the naive port. That is the lesson.

Output contract

For an input named foo, produce exactly these artifacts:
