The functionality described below will be available in Q1 2026.
Zama is a Web3 privacy technology provider focused on enabling confidential assets and smart contracts.
On Bron, Zama technology makes it possible to:
Hide transaction amounts on public blockchains
Keep transactions verifiable without revealing balances
Convert assets between public and confidential formats
Zama does not custody funds and cannot access user balances. All actions are initiated and confirmed by you in Bron.
1. How Shielding Works
When you shield a supported token:
The public token is converted into its confidential version
The transaction is recorded on-chain
The amount is hidden from public view
The confidential balance is visible only inside Bron
You can unshield the token at any time to return it to its standard, publicly visible form.
2. How to Shield a Token
Open Bron and go to Holdings
Select a supported token
Tap Shield
Enter the amount
Confirm the transaction
When shielding tokens, make sure to sign twice: once to approve the transaction, and once to approve the shielding.
Once completed:
Your asset appears in its confidential form
Your confidential balance updates in Bron
The transaction amount is not publicly visible on-chain
3. What Is Visible On-Chain
When you send or receive a shielded token:
Visible:
Transaction hash
Sender and receiver addresses
Transaction status
Hidden:
Transaction amount
Shielded balance changes
Observers can verify that a transaction occurred — without seeing how much was transferred.
4. How to Unshield a Token
You can convert a shielded token back to its public version at any time.
Step-by-step
Open the shielded token in your holdings
Tap Unshield
Enter the amount
Confirm the transaction
After unshielding:
The asset returns to its public form
Amounts become visible on-chain again
Funds remain fully usable and transferable
There is no lock-up period.
5. Fees & Network
Shielding and unshielding are on-chain transactions
Standard network (gas) fees apply
Fees depend on the selected network and network conditions
