ContractScan

Foundry Business-Logic Preflight Pack

One-time download · Local Foundry / CLI · Early bird $99 (regular $149 later)

Checklist + 10 pattern cards + 5 Foundry test stubs to accelerate business-logic pre-checks before you ship or start a review.

Not an audit. Not an automatic exploit finder. Not ContractScan the web scanner. Does not claim to scan business-logic vulnerabilities end-to-end.

Who it’s for

If you want a free first-pass on common static issues, use the ContractScan web scanner separately — it is not this product and does not claim to find business-logic bugs.

What’s inside

ItemDetail
CHECKLIST.mdThreat model → invariants → Foundry tests → config residual risk → sign-off
patterns/10 short cards: when to apply, what to look for, Foundry action sketch, invariant ideas
foundry-stubs/5 copy-paste .t.sol skeletons (TODOs to bind your vault/router/token)
CI.mdMinimal GitHub Actions wiring for one stub
README.md + LICENSE-BUYER.txtEnglish quick start; personal/team use; no resale; as-is

Public sample card titles (full text of 2 cards ships as free preview in the product materials; the other 8 cards and all stubs are in the paid zip only): FirstDepositDonation, PairSkimSync.

How it works (about 15 minutes)

  1. Fill a short threat model from the checklist (assets, actors, value exits).
  2. Mark matching pattern cards against your codebase.
  3. Copy 1–2 stubs into test/preflight/, replace TODOs.
  4. Run forge test --match-path test/preflight -vv.
  5. Optionally add the CI snippet so the same harness runs on every PR.

You leave with: a written asset/actor list, named invariants, and at least one fuzz/invariant harness you own.

What’s NOT included

FAQ

Is this the ContractScan web scanner?

No. The pack is a local Foundry preflight kit. The free web scanner is a separate facade for common static issues with honest limitations.

Do I need to upload my code?

No. Everything runs on your machine with Foundry.

Will the stubs compile out of the box against my protocol?

No. They are skeletons with TODOs. You bind your interfaces and addresses.

Can I share or resell the zip?

No. Buyer license is personal/team use only; no redistribution or resale. See LICENSE-BUYER.txt in the zip.

What if my download is corrupt?

7-day file replacement if files are missing or corrupt after purchase. Email support@contract-scan.dev.

Do you answer “is my contract safe?”

No. Support is documentation + file reissue only.

Refunds?

Digital download; policy is set by Creem / seller at checkout. Prefer reviewing the public sample card titles and this page before buying. See also Terms.
