NYDFS Part 504 for crypto trusts: building a defensible monitoring record
Part 504 is a program rule with an annual signature attached. The hard part is not running a transaction-monitoring tool. It is proving, a year later, that the program operated as designed. Here is what Part 504 expects, and how one record makes the certification a query.
What Part 504 requires
3 NYCRR Part 504 requires NYDFS-regulated institutions to maintain two programs. A transaction-monitoring program, risk-based and reasonably designed to monitor for potential Bank Secrecy Act and anti-money-laundering violations and to support suspicious-activity reporting; and a watchlist-filtering program, reasonably designed to screen against sanctions and other lists. Both must be validated, governed, and built on inputs whose integrity you can stand behind.
On top of the programs sits the part that makes Part 504 distinctive: an annual certification that the programs comply. A senior officer or the board attests to it. Confirm the current certification format and timing with your counsel, since DFS has revised how the attestation is made.
The hard part is the evidence, not the monitoring
Most crypto trusts already run a capable monitoring vendor and a case tool. The strain shows up at certification time, because the certification is a statement about the whole year. To stand behind it you need to show the alerts and how they were dispositioned, the tuning and validation behind the rules and filters, the change control on detection logic, the data-integrity controls on the inputs, and the governance trail. When those records live across a monitoring console, a case system, a spreadsheet of tuning decisions, and email approvals, assembling them is a project, and the project repeats every year.
One record per customer: the certification becomes a query
FinQub is the single source of truth for fintech risk decisions. It sits alongside your monitoring, screening, and case tools and lands every signal each one produces on one record per customer, with the decision it informed.
Every alert keeps its lineage. The rule and threshold that fired, the watchlist screen and its result, the disposition, who reached it, and the policy version in force are on the record together, so the question "show me how this was handled" is one retrieval.
FinQub aggregates, your tools still run. Your monitoring vendor generates the alerts and your analysts work them in the case tool. A vendor score is a signal, not a decision. FinQub records the decision and the evidence beneath it, so the program leaves a continuous, queryable trail rather than a year-end reconstruction.
The look-back is point in time. Because each decision is pinned to the policy version that applied, you can show what the program decided, on what evidence, under which rules, as of any past date. That is the posture a certification asks for.
A checklist for a certification-ready program
- Confirm your charter is in Part 504 scope and which programs it covers.
- Keep each alert's disposition, rationale, and decider attached to the alert, not in a side log.
- Hold tuning and validation records for your rules and filters with the versions they applied to.
- Log change control on detection logic with the version diff and the approver.
- Confirm you can reproduce the program's decisions, with evidence, as of any past date on one query.
Frequently asked questions
Does Part 504 apply to crypto trusts?
Part 504 (3 NYCRR Part 504) applies to institutions regulated under the New York Banking Law and the DFS financial-services rules, which includes NY limited-purpose trust companies and DFS-regulated virtual-currency businesses. If your charter or license is supervised by NYDFS, map your transaction-monitoring and watchlist-filtering programs to Part 504 and confirm the current scope with your counsel.
What does the annual certification actually attest to?
It attests that your transaction-monitoring program and your watchlist-filtering program are reasonably designed and operating, with the governance, validation, and data integrity Part 504 expects. It is a statement about how the program ran all year, which is exactly why the evidence behind it has to be reproducible, not reconstructed each spring.
Does FinQub replace my transaction-monitoring vendor?
No. Your monitoring vendor still generates alerts and your case tool still works them. FinQub is the record they land on: every alert, the rule and threshold that fired it, the disposition and who reached it, the watchlist screen and its result, and the policy version in force are on one record per customer. The certification look-back becomes a query against that record.
What evidence supports a Part 504 program?
Alerts and their dispositions, the tuning and validation records for your rules and filters, change control on detection logic, data-integrity controls on the inputs, and the governance trail. When all of that is attached to the decisions it produced, demonstrating the program operated as designed is a retrieval, not a rebuild.
The monitoring and certification record runs on your own vendor stack. FinQub is the single source of truth for fintech risk decisions underneath it. See the Travel Rule applied the same way, or book a short walkthrough below.
