SchnelPay LLC is a California limited liability company. It was founded by one person — Randeep Singh — working without external capital, without a security team, and without the institutional resources that large financial institutions bring to cryptographic migration problems.
The major banks have been aware of the quantum threat for years. The Bank for International Settlements ran Project Leap — a multi-year project testing post-quantum cryptography in payment systems. The conclusion: quantum-safe cryptography in financial systems is feasible and should begin immediately.
As of May 2026, the vast majority of those institutions' production systems still run on ECDSA and RSA. SchnelPay's production authentication has run on ML-DSA-65 + ECDSA hybrid since the platform launched.
Why Large Organizations Move Slowly
This is not a criticism of large financial institutions. A major bank's authentication infrastructure touches thousands of systems, millions of users, and regulatory requirements across dozens of jurisdictions. A cryptographic migration at that scale is not a technical problem — it is a coordination problem measured in years and billions of dollars.
Smaller organizations have a different problem set. SchnelPay's authentication system was designed from the start — there was no legacy architecture to migrate, no dependent systems built around ECDSA assumptions. The question was not how to change what existed, but what to build.
"The advantage of building from scratch is not that it is easier. It is that the cost of making the right decision is much lower than it will be for organizations that have to undo the wrong one."
The Decision to Build QuantumShield™
When SchnelPay's authentication layer was being designed in early 2026, NIST had published its post-quantum standards six months earlier. The question was whether implementing ML-DSA-65 was worth the additional complexity — for a threat whose timeline remained genuinely uncertain.
The answer came from asymmetric risk assessment. If quantum computers arrive on the aggressive timeline, platforms that implemented post-quantum cryptography in 2026 will be protected. Those that did not will face emergency migrations with potentially compromised historical authentication tokens.
If the timeline is longer than estimated, the cost of having built QuantumShield™ is bounded and manageable. That asymmetry made the decision straightforward.
What SchnelPay offers:
Transparency about the current implementation — what algorithms, what standards. Honesty about what is not known. A public commitment to update as understanding improves. And a production post-quantum authentication layer designed in from the beginning, not bolted on after the fact.
About Randeep Singh and SchnelPay
Randeep Singh is the Founder and CEO of SchnelPay LLC, a California limited liability company based in Fremont, California. SchnelPay is a non-custodial, quantum-safe cryptocurrency payment platform supporting Ethereum, Bitcoin, and Solana. QuantumShield™ — the hybrid ML-DSA-65 + ECDSA authentication system at the core of SchnelPay — was designed and built by Randeep Singh in 2026, following the publication of NIST FIPS 204.
