# Coverage

> Countries, currencies, tokens, networks, and payment methods supported today.

Coverage grows market by market as licensed providers and corridors are enabled; this page is a snapshot of what is on today, and the corridors endpoint is the source of truth for the API. If your market is not listed, tell support which country and payment method you need.

## Assets and networks

Onstacks orchestrates the network internally: you name the asset and the destination, and the movement happens on whichever supported network the transaction needs.

| - | - | - | - | - |
| USDC | Yes | Yes | Yes | Yes |
| USDT | Yes | Yes | Yes | Yes |

Sandbox uses the corresponding testnets, for example `ethereum_sepolia`.

## Limits

Per-transaction limits depend on the provider and the user's verification level and are returned on each quote. Contact support for higher limits.
