JPMorgan froze the accounts of two YC-backed stablecoin startups — BlindPay and Kontigo — over exposure to sanctioned jurisdictions (Venezuela). Their banking access disappeared.
At-execution sanctions enforcement for stablecoin payments
Block sanctioned transfers before they ever send.
Stablecoin Sentry screens every outbound USDC transfer against OFAC, UN, and EU sanctions lists in under 500ms — then automatically blocks, flags, or allows it, and writes an immutable audit trail your sponsor bank can inspect. A flag without a block is not a control.
Pre-product. We're working with a small number of design partners. 30-minute call, no obligation.

OFAC is strict liability. You can be penalized even for an unknowing violation — up to $377,700 per violation, or twice the transaction value, whichever is greater.
The joint FinCEN/OFAC GENIUS Act rule (published April 10, 2026) would, for the first time, require stablecoin issuers to maintain an effective sanctions compliance program and the technical ability to block, freeze, and reject transactions. Comment period closes June 9, 2026.
If your sponsor bank decides you're a liability, you don't get a warning. You get de-banked.
An enforcement layer that lives in the payment path.
Stablecoin Sentry is synchronous middleware that sits inside your outbound payment flow. Every transfer is screened and adjudicated before it leaves — block, flag, or allow — in under 500ms. Every decision is written to a tamper-evident, bank-inspectable audit trail.
A flag without a block is not a control.
How it works.
One synchronous API call in your outbound payment flow.
01
Screen
Each outbound transfer hits our API synchronously and is checked against OFAC SDN, UN, and EU sanctions lists plus risk intelligence.
02
Decide
< 500 msSentry returns block / flag / allow before the transaction sends. No async alert that arrives after the money is gone.
03
Prove
Every decision is recorded in an immutable, tamper-evident audit trail your sponsor bank and examiners can inspect on demand.
Monitoring tells you what happened. Enforcement stops it from happening.

The capability gap
No team of analysts can do synchronous sub-500ms block-before-send with a bank-grade audit trail. This is an infrastructure problem, not a headcount problem.
This is a risk-transfer product. We move the strict-liability exposure off your desk and into the payment path.
We're recruiting a small group of design partners.
What you get
- Early access and influence over the roadmap
- A direct line to the founder
- Preferential early pricing
- A sanctions-enforcement layer built around your exact corridors and sponsor-bank requirements
What we ask
- Weekly feedback during the build
- Your real-world corridors, edge cases, and sponsor-bank screening requirements
- Willingness to pilot
We're intentionally keeping this cohort small so each partner gets real engineering attention.
Built by people who've lived this problem.

LinkedInWhy we're building this
The GENIUS Act rulemaking makes a sanctions-compliance program with the technical ability to block, freeze, and reject transactions a regulatory requirement for stablecoin issuers — not an aspiration. OFAC is strict liability, sponsor banks are already de-risking high-corridor stablecoin startups, and monitoring tools alert after the money is gone. Enforcement-at-execution is the layer the industry doesn't have. We're building it with the operators who will depend on it.
Security & posture
Built to bank-examination standards. We map to OFAC, BSA/AML, and the GENIUS Act sanctions-compliance requirements. Security architecture and SOC 2 roadmap available to design partners under NDA.
Questions, answered.
If a sanctioned transfer left your platform tomorrow, would you catch it before it sent?
Book a 30-minute discovery call. We'll walk your corridors and sponsor-bank requirements and show you what enforcement-at-execution looks like.
