When building integrations, testing workflows, or experimenting with workspace settings, it’s safer to do so outside of a production environment — without using real assets or risking mainnet operations.
Bron offers sandbox workspaces that support both mainnet and testnet accounts. These workspaces are fully functional and can be used to test:
Transaction flows (inbound, outbound, and internal transactions).
⚠️ Note: Features provided by Bron partners (e.g. Staking, Swaps) are not always compatible with testnets. Please check the documentation for each specific feature to confirm testnet support.
What is a Sandbox Workspace?
A sandbox workspace is a special type of workspace where you can test all major Bron functions using mainnet or testnet networks. It is entirely separate from your production workspace.
You can create testnet or mainnet accounts in sandbox workspaces.
All transactions and settings are fully isolated from your production environment.
Sandbox workspaces are clearly marked with a yellow "Sandbox" banner and a "Sandbox" label in the workspace selector.

How to Create a Sandbox Workspace
Click your current workspace name in the left-hand sidebar.
Select "Create a new workspace".
In the popup:
Enable the "Sandbox workspace" toggle.
Set the workspace name and Bron tag.
Then click Create.
Your sandbox workspace is now ready. You can create accounts, configure policies, and integrate APIs just like in a mainnet workspace.
Switching Between Workspaces
You can switch between mainnet and sandbox workspaces using the workspace selector in the sidebar. Each environment is completely independent: team members, accounts, and settings are not shared between them.
💡 Transfer by Tag is not available in Sandbox workspaces — Bron Tags work on Mainnet only.
Using Testnets
To test transactions on testnets:
Go to your sandbox workspace.
Create a new account.
In the account creation popup, toggle "Testnet" to enable testnet mode.
You can now simulate transactions without using real assets.
