# Supported currencies and methods

> Which fiat currencies, stablecoins, networks, and payment methods you can use.

## Fiat currencies

We support a growing list of fiat currencies, including:

| Currency | Onramp: customer pays with | Offramp: customer is paid to |
| - | - | - |
| **NGN** Nigerian naira | Bank transfer (`bank_transfer`) | Bank account (`bank_transfer`) |
| **GHS** Ghanaian cedi | Mobile money (`momo`) | Bank account (`bank_transfer`) or mobile money (`momo`) |

> [!NOTE]
>
> New fiat currencies are added regularly and announced in the [Changelog](https://docs.bridge.linkio.world/changelog.md). To see exactly what your business can use right now, check [Currency pairs](https://docs.bridge.linkio.world/control-app/ramp-pairs.md) in the Bridge app or call [List payment methods](https://docs.bridge.linkio.world/api-reference/lookups/methods.md).

## Stablecoins

| Stablecoin | Onramp | Offramp |
| - | - | - |
| **USDC** | Yes | Yes |
| **USDT** | Yes | Yes |

USDC is the main stablecoin used in these docs. USDT works the same way: send `USDT` wherever the examples show `USDC`.

## Networks

This is our growing list of supported networks.  Your customer's wallet must be on the same network you choose in the quote.

| Network | Value to send |
| - | - |
| Base | `base` |
| Polygon | `polygon` |
| BNB Smart Chain | `bsc` |
| Ethereum | `ethereum` |
| Tron | `tron` |
| Solana | `solana` |

> [!WARNING]
>
> Sending stablecoins on the wrong network can lose the funds. Always check that the wallet address and the `network` match.

We check that wallet addresses look right for the network you choose. A wrong address is rejected before the payment is created.

## Mobile money networks

For GHS:

| Network | Code |
| - | - |
| MTN | `0004` |
| Vodafone | `0006` |
| AirtelTigo (Airtel) | `0005` |
| AirtelTigo (Tigo) | `0009` |

You can also get this list from the API: [List mobile money networks](https://docs.bridge.linkio.world/api-reference/lookups/momo-networks.md).

## Banks

Get the list of banks and their codes from the API: [List banks](https://docs.bridge.linkio.world/api-reference/lookups/banks.md). Use the bank's code when you send payout details.

## Payout account details

When you create an offramp, you send the account that should receive the money. The fields depend on the currency and method.
