### Currencies

These currencies support both onramp (fiat to crypto) and offramp (crypto to fiat) for Business-to-Business (B2B), Business-to-Individual (B2C), and Individual-to-Individual (I2I) transactions.

| Currency | Payment Method                          | Average Delivery Speed                |
| -------- | --------------------------------------- | ------------------------------------- |
| **USD**  | ACH, FedWire                            | Same Day (T+1 if outside cutoff time) |
| **EUR**  | SEPA Instant (SEPA Credit if 100k+ EUR) | Real-time                             |

{% hint style="info" %}
Settlement timelines may not be
&#x20;instant. (This is due to the applicable jurisdiction, payment rail used, cross-border nature
&#x20;of a transaction, settlement protocols, processing windows, and banking infrastructure
&#x20;involved, and may take up to seven days).
{% endhint %}

### Payment Rails

The following table outlines our supported payment methods.

<table data-header-hidden><thead><tr><th></th><th width="432.199951171875"></th><th align="center"></th></tr></thead><tbody><tr><td><strong>Payment Method</strong></td><td><strong>Description</strong></td><td align="center"><strong>Availability</strong></td></tr><tr><td><strong>SEPA (Instant)</strong></td><td>Instant EEA transactions sub €100k</td><td align="center">✅</td></tr><tr><td><strong>SEPA (Credit)</strong></td><td>Usually 24 hours for transactions greater than €100k</td><td align="center">✅</td></tr><tr><td><strong>ACH</strong></td><td>Common for domestic transfers within the US</td><td align="center">✅</td></tr><tr><td><strong>Wire</strong></td><td>Common for domestic transfers within the US</td><td align="center">✅</td></tr></tbody></table>

#### Third Party Payments

**Use Case**

* **Onramp**: Accept fiat payments from external bank accounts as a third-party source.
* **Offramp:** Disburse fiat payouts to external bank accounts that are not owned by the initiating end customer (e.g., vendor, beneficiary, or third party).

Key use case is for users to be able to **offramp / send stablecoins into third party bank accounts**:

* Crypto companies paying suppliers (USDC to EURO)
* Payroll originating in USDC to get delivered as USD or EUR into bank accounts
* Companies pay with stablecoins, freelancers receive fiat.
* Cross border payments

{% hint style="info" %}
Customers from the USA can’t enable EURO 3rd party accounts.
