Stablecoin on-ramp
Stablecoin on-ramp refers to a service that converts fiat currency into stablecoins. A typical example is wiring dollars to an issuer or exchange and receiving the equivalent tokens.
How it works
Institutional on-ramps often run through the issuer. With Circle Mint, a customer wires fiat from a linked bank account and receives USDC at a 1:1 ratio. Domestic wires received before the daily cut-off settle the same business day. International wires take one to three business days.
Other on-ramps include exchanges, brokers and OTC desks. FATF treats intermediaries that exchange stablecoins for fiat as virtual asset service providers. Regulated providers must collect customer information and screen for sanctions. Direct redemption with an issuer is typically limited to its primary customers.
For cross-border firms, the on-ramp sets when a stablecoin leg can start. A late wire can push minting to the next business day. Pitfalls include ignoring bank cut-offs on the fiat side and not checking the provider's licenses. Treat fiat sent to an on-ramp as funds in flight until the tokens arrive.
Example
Illustrative example: A US firm wires $2,000,000 to its on-ramp provider at 14:00 ET, before the provider's daily cut-off. At a 1:1 rate it receives 2,000,000 USDC the same business day. The $2,000,000 counts as funds in flight from wire to token receipt.
Frequently asked questions
Is an on-ramp the same as buying stablecoins on an exchange?
An exchange purchase is one kind of on-ramp. Issuer minting, OTC desks and payment providers are others. Each has different limits, fees, settlement times and compliance checks.
What compliance checks should we expect?
Expect customer due diligence and sanctions screening. FATF says regulated providers exchanging stablecoins for backing assets must collect customer information. Some providers also verify wallet addresses before transfers.
