# Sandbox

> Use the Sandbox environment to mock flows, execute transfers and test integrations.

The Developer Sandbox replicates core [v2 API](/api-reference) functionality with an automated system that uses test funds to simulate normal activities, including a few Sandbox-only endpoints.

> To start using the Sandbox environment, [create a Developer account](https://dashboard.sandbox.paxos.com/).

## Sandbox Testnets and Devnets

When you use [Create Sandbox Deposit](/api-reference/endpoints/sandbox-deposits/create-sandbox-deposit) to fund a Profile, the platform creates the asset on the testing network.
The asset can then be [transferred](/api-reference/endpoints/crypto-withdrawals/create-crypto-withdrawal) to any off-platform address that supports the test network.
Similarly, when using [create a deposit address](/api-reference/endpoints/deposit-addresses/create-deposit-address) in Sandbox, the generated address can be used to transfer test assets to the Paxos platform.

## Sandbox Withdrawal Limits

The Sandbox environment has withdrawal limits per transaction to preserve the limited supply of test coins available for customer testing. While you can execute multiple transactions, each individual withdrawal must stay within these limits:

| Asset  | Maximum Withdrawal per Transaction |
| ------ | ---------------------------------- |
| BTC    | 0.002                              |
| ETH    | 0.05                               |
| BCH    | 0.05                               |

## Sandbox Identity Testing

When testing the [Identity APIs](/api-reference/endpoints/identity) in Sandbox, you may be blocked by a verification process.
If this is the case, use [Sandbox Set Identity Status](/api-reference/endpoints/sandbox-identity/sandbox-set-identity-status) to change `id_verification_status` and `sanctions_verification_status` to "APPROVED"`and enable an individual identity to transact during Sandbox testing.
To enable the Institution to transact during Sandbox testing, set `sanctions\_verification\_status` to \"APPROVED"`.

## Sandbox Fiat Transfer Testing

To test [Fiat Transfers API](/api-reference/endpoints/fiat-transfers) in Sandbox, the [Initiate Sandbox Fiat Deposit](/api-reference/endpoints/sandbox-fiat-transfers) endpoint starts a test fiat deposit that will be processed based on the `memo_id` from a previous [Fiat Deposit Instructions](/api-reference/endpoints/fiat-transfers/list-fiat-deposit-instructions) response.
Learn more in the [Fiat Transfer Guide](/guides/developer/fiat-transfers/quickstart#2-send-fiat-to-paxos).

> When [creating API credentials](/guides/developer/credentials) via the Dashboard, the `transfer:write_sandbox_fiat_deposit` scope may not appear in the UI.
> Including the scope when [authenticating](/guides/developer/authenticate) may result in an `invalid_scope` error.
> Contact [Support](https://support.paxos.com) if you run into any issues using this scope.
