### Wallet Reference

| Key    | Currency          | Notes                                                                     |
| ------ | ----------------- | ------------------------------------------------------------------------- |
| `sol`  | USDC on Solana    | Primary deposit chain — send USDC here                                    |
| `xdc`  | USDC on XDC       | Alternative deposit chain — `null` if XDC is not enabled for your program |
| `usdc` | USD spend balance | Available for funding USD-denomination cards                              |
| `eur`  | EUR spend balance | Available for funding EUR-denomination cards                              |
| `gbp`  | GBP spend balance | Available for funding GBP-denomination cards                              |

`usdc`, `eur`, and `gbp` balances have no `address` field — they are settlement balances managed internally. `sol` and `xdc` include an `address` field for depositing USDC.

Use [Swap Token](/api-reference/issuer/swap-token) to convert between `usdc`, `eur`, and `gbp` balances.
