Same multi-engine smart-contract audit stack on every paid tier — IR detector, Claude AI, Mythril, Foundry fuzzing, Wake, and on-chain analysis. Volume, bundled compliance attestations, and service level differentiate. No feature-gating tricks.
Below is every detection layer SolSentinel runs. Notice the columns are nearly identical — that's intentional. We don't artificially cripple lower tiers. You're paying for volume, bundled compliance, and service level, not for which engines we let you use.

So Free can stay genuinely free forever (no card, no trial timer). The Free tier runs our deterministic IR + Solhint engines — the same detector that powers our 88.6% recall benchmark on Code4rena HIGH-severity findings. Every paid tier adds Claude AI on top, which catches the novel protocol- specific logic bugs that pattern detectors structurally cannot see.
Yes. We don't artificially cripple lower paid tiers. You get the full multi-engine stack (IR + Claude + Mythril + Foundry + Wake + on-chain) on every paid plan. Tiers differ in: scan volume, overage rate, bundled compliance attestations, team seats, retention, and service level. The one true engine upgrade is dual-AI Claude+Grok consensus, which is reserved for Audit Infrastructure (custom pricing) because it literally costs us 2× the API per scan.
If you exceed your included monthly scans, every extra audit is billed at your tier's overage rate: $69/scan on Pro Builder, $59/scan on Protocol Team. Charges accrue on your next subscription invoice. We don't block you from running audits when you go over — security shouldn't have a "you're over the limit" wall.
Break-even on Pro Builder is 5 PAYG scans/month. If you run 5+ audits per month, Pro saves you money plus gives you GitHub App, projects, and API access. PAYG is best for trying SolSentinel without commitment or for occasional one-off audits.
Yes, anytime from your account. We don't issue refunds for partial months, but you keep full access until your billing period ends. Downgrades take effect at the next renewal; upgrades are prorated immediately.
For comparison: SOC 2 Type I attestation from a CPA firm runs $5,000–$15,000. MiCA gap analysis from a regulatory consultant runs $10,000+. Our AI-assisted attestation produces the structured per-criterion analysis (MiCA Articles 30/50/68/75/76, FIT21 §§202(b)/301/404/501, SOC 2 CC6.1/CC6.6/CC7.1/A1.2/PI1.4) for $499. It's the AI-driven version of the artifact, suitable for internal review or to hand to a CPA who'll sign their version. We're the only product that has this.
Three things separate it from "we matched the word reentrancy":
/api/compliance/verify/{fingerprint}.What we are NOT: a licensed CPA firm. SOC 2 formal reports require CPA signature. We produce the AI-driven artifact + the structured data your CPA can use as input.
