Crypto Teller: QvaPay's AI-Optimized Crypto Processor
Crypto Teller, our in-house crypto processor, records the address and hash on every deposit and withdrawal, and Sentinel clears addresses before a coin moves.

A lot of dollars reach Cuba as stablecoins. Most compliance programs lose sight of them at the processor: an amount comes through, the sender doesn't. We built our own processor so that never happens on QvaPay.
What it does
Crypto Teller, built in-house, gives each deposit its own address, writes the transaction hash to the record at execution, and broadcasts no withdrawal until Sentinel clears the destination address. It runs on the same AI stack as Sentinel and Bouncer, and every case goes to our compliance officer.
| Flow | Legitimate | Bad actor, and what happens |
|---|---|---|
| Remittance | A nephew in Miami sends USDC to his aunt in Camagüey. | The deposit comes from a wallet on the SDN list. Never credited: blocked and reported to OFAC. |
| Business funding | A workshop's buyer abroad pays an invoice in USDC. | Dozens of small deposits from fresh wallets to stay under thresholds. Every address is on the record; Bouncer sees the pattern the same day. |
| Withdrawal | A developer moves her earnings to her own wallet. | A withdrawal to an address tied to a blocked party. Never broadcast; rejected and reported to OFAC. |
At Uphold and Airtm, crypto compliance meant stitching vendors together and asking analysts to reconcile what each one saw. The risk lived in the gaps. Erich built Crypto Teller so the record is complete by construction.
Every stablecoin dollar on the record is a dollar a U.S. bank can stand behind, and one that can grow with Cuba’s private sector.
Crypto Teller settles every USDC deposit and withdrawal, with both ends screened.
| Flow | How we grow it | U.S. tech meets Cuban talent |
|---|---|---|
| Crypto funding and withdrawals Own funds, screened addresses · withdrawals by persons in Cuba: pending with OFAC | USDC from and to screened wallets, settled by Crypto Teller. | Cubans hold dollars on a phone, the way the rest of the internet does. |
The potential. Remittances into Cuba run an estimated $1.1–2B a year (2024; estimates vary). At the Dominican Republic’s rate per person, Cuba would receive about $9.8B, five to nine times today. That is the market QvaPay is built to serve.
| Market | Cuba today | Cuba at the Dominican Republic’s rate per person |
|---|---|---|
| Remittances received | $1.1–2B 2024 est., estimates vary | $9.8B DR total $11.9B (2025) |
A scenario, not a forecast. The Dominican Republic received $11.9B in remittances in 2025 across 11.4 million people, about $1,040 a person; at that rate Cuba’s 9.43 million people would receive about $9.8B a year, five to nine times today. Method and sources.
