ProofForge puts financial-code fixes through Lean
A verification harness that presents Lean 4 specifications, counterexamples, and proof results for financial code, including fixes proposed by Meta’s Muse models.
- For
- Formal-methods and financial-software developers
- Worth noticing
- A displayed Compound run is marked incomplete: one lemma remains `sorry`.
Field notes
The page lays out requirements as Lean 4 theorems, with proof lemmas and repaired code shown in layers; visitors can inspect named task runs, Lean source, reports, counterexamples, and Passport records. Its examples span Balancer V2, Compound, Cetus, Euler Finance, Hundred Finance, and Knight Capital. The displayed Compound run A2-topdown-3 is explicitly marked incomplete because one lemma remains `sorry`, making a failed proof visible rather than smoothing it away.
