Sandbox
The Developer Sandbox replicates core v2 API functionality with an automated system that uses test fund to simulate normal activities, including a few Sandbox-only endpoints.
To start using the Sandbox environment, create a Developer account.
Sandbox Testnets and Devnets
When you use Create Sandbox Deposit to fund a Profile, the platform creates the asset on the testing network. The asset can then be transferred to any off-platform address that supports the test network. Similarly, when using create a deposit address in Sandbox, the generated address can be used to transfer test assets to the Paxos platform.
| Crypto Network | Supported Testnet/Devnet |
|---|---|
| Arbitrum One | Sepolia |
| Bitcoin | Testnet3 |
| Bitcoin Cash | Testnet |
| Ethereum | Sepolia |
| Litecoin | Testnet |
| Polygon POS | Sepolia |
| Solana | Devnet |
Sandbox Identity Testing
When testing the Identity APIs in Sandbox, you may be blocked by a verification process.
If this is the case, use 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 in Sandbox, the Initiate Sandbox Fiat Deposit endpoint starts test fiat deposit that will be processed based on the memo_id from a previous Fiat Deposit Instructions response.
Learn more in the Fiat Transfer Guide.
When creating API credentials via the Dashboard, the
transfer:write_sandbox_fiat_depositscope may not appear in the UI. Including the scope when authenticating may result in aninvalid_scopeerror. Contact Support if you run into any issues using this scope.
