Storage-layout collision risk across upgrades
Marinade Finance's assessment for RD-F-142 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Solana BPF programs do not use EVM-style storage slots. Marinade uses Anchor with explicit typed account structs. The v2 upgrade (2023) maintained backward-compatible state layout; two auditors reviewed the upgrade. Anchor discriminator-based validation prevents account-type confusion across upgrades.
