Proving tax residency to open an NRE account, release withheld dividends, or file a DTAA claim means physically handing over your passport history, flight records, bank statements, and employer letters. A compliance officer gets your complete travel biography. They needed one answer: resident or not.
India's DPDP Act 2023. Singapore's PDPA 2012. GDPR Article 5(1)(c). Collecting more personal data than necessary for a stated purpose is not poor practice — it is a regulatory violation. Every document submitted for manual residency review is a liability sitting on an institution's server.
A private bank processing 4,000 NRI and expatriate accounts spends more than 5,000 compliance hours per year on manual residency verification. The FATCA/CRS backlog alone runs to months. This is not an edge case — it is a systemic failure embedded in every institution that handles cross-border wealth.
"UTRLG converts a privacy-invasive, 3-week document process into a 30-second cryptographic verification."
Three banks. Three compliance queues. The same passport pages, boarding pass scans, and employer letters — submitted every year, stored indefinitely, used for a decision that takes 30 seconds to make once someone reads them. UTRLG generates one cryptographic token. All three banks verify it in their systems. Arjun's travel history stays private.
Her team processes 4,000+ residency verifications per year. Each one is 60–90 minutes of manual review, a scanned passport in a compliance folder, and a PDPA liability she cannot quantify. UTRLG gives her a three-line API call that returns a verified residency status in 1.2 seconds — and a clean audit log she can show any regulator.
Every investment decision for every UHNW client turns on residency status. Treaty relief, withholding rates, reporting obligations — all downstream of a question that today requires accumulating documents the clients would rather not share. UTRLG gives him a verifiable, cryptographically-anchored answer he can file in the client record and stand behind.
Zero-Knowledge Proofs allow a computation to be verified as correct without revealing the inputs that produced it. UTRLG's circuit evaluates your travel evidence — counting your days in a jurisdiction against the statutory threshold — and generates a mathematical proof that the count is accurate.
The proof travels to the institution. Your evidence never does. This is not a policy commitment. It is a mathematical guarantee.
"Imagine proving you know the combination to a safe by opening it — without ever speaking the combination aloud."
