# On-ramps and off-ramps

> Convert between fiat and stablecoins via OMS or third-party providers on Polygon.

The Open Money Stack provides regulated, enterprise-grade on-ramp and off-ramp infrastructure with KYC, AML, and compliance built in. Third-party providers are also available for teams not using OMS directly.

## OMS on-ramps and off-ramps

OMS handles both directions. The quote-and-execute pattern applies to crypto sends and payouts; cash-in and virtual accounts auto-create their transactions when funds arrive.

>
> Fund a wallet from a bank account or cash at a retail location and deliver stablecoins to a wallet.

> [card] [Crypto to fiat](https://docs.polygon.technology/payments/guides/crypto-to-fiat.md)

> Pay out USDC from a custodial wallet to a bank account, card, or cash pickup, or to any wallet or address.

> [card] [Cash-in](https://docs.polygon.technology/payments/guides/cash-in.md)

> Let a customer deposit physical cash at a retail location and receive USDC in their wallet.

> [card] [Virtual accounts](https://docs.polygon.technology/payments/guides/virtual-accounts.md)
>
> Give a customer a dedicated bank account number that auto-converts incoming fiat to USDC.

Supported bank rails include ACH, same-day ACH, wire, and RTP for US accounts, SWIFT for IBAN accounts, and Canadian bank accounts. Debit card funding and payouts are available, as is cash: deposits at partner retail locations across the US, and cash pickup for payouts (up to \$400 per transaction).
