What Is a Test Network?

Many blockchains provide separate testing environments known as “testnets,” which allow developers to test applications using test assets before deploying to the main network (“mainnet”). The Sandbox environment operates on testnets only and supports test assets only. Please review the supported chains, currencies, and capabilities below before initiating any deposit or withdrawal tests.

Notes

All listed assets are testnet assets only and have no real-world value.

Support status may vary by chain (for example, address generation or withdrawals may not be available on all testnets).

Attempting to deposit unsupported assets or use unsupported chains may result in failed or unrecognized transactions.

Getting Test USDC

To test deposits and withdrawals in the Sandbox, you must use testnet USDC. You can obtain test USDC from the following faucet: https://usdcfaucet.com/

After receiving the USDC test, connect your wallet to the correct test network and confirm the USDC contract address matches the one listed in the table above. Then, use the generated deposit address (if supported) to complete your test transaction.
