Hi Fireblocks team,

Our Developer Sandbox workspace is showing the banner “There are **3 days remaining** before your sandbox environment expires. Upgrade now to get access to a mainnet workspace."

We’re actively developing and testing our integration and would appreciate an extension of the sandbox environment.

Workspace: **Hengbao International - Herman Santoso**  
Account email: [herman@hengbao.com](mailto:herman@hengbao.com)  
Use case: Integration of fireblocks vault across multiple chains`

Thank you.
