# Withdrawal Limits (Server)

> Understand how withdrawal limits work and how to increase them from your server.

## How Withdrawal Limits Work

When the ZBD Earn SDK is active on the client, the device pings the server every 20 seconds. Depending on the reward schedule configured for your app, this automatically increases the player's withdrawal limit every minute by a set amount.

## Increase Withdrawal Limit from Server

You may want to increase a user's withdrawal limit by a fixed amount at any time from your server. For example, if you receive a callback from your MMP or an in-app purchase receipt confirming that a user monetized, you can increase their withdrawal limit accordingly.

### Choosing the right currency

The `currency` field must match the reward currency your game uses:

| Your game                                   | `currency` |
| ------------------------------------------- | ---------- |
| In-game points / soft currency (most games) | `POINT`    |
| Bitcoin-denominated                         | `MSATS`    |

Most games use `POINT`, so that's the default. Only set `MSATS` if your game is Bitcoin-denominated.

<Note>
  If you're not sure which currency applies to your game, reach out to your account manager to clarify before setting withdrawal limits.
