Zama: Merkl confidential incentive rewards are now available for collection

On October 19, the team from the fully homomorphic encryption company Zama announced that users participating in the incentive distribution platform Merkl on the Zama confidential vault can now directly receive cZAMA rewards in the Zama app. The rewards are settled through confidential transfers, and both the positions and the reward amounts remain confidential from deposit to distribution.

In September 2026, Zama launched confidential access to 16 selected vaults on the lending protocol Morpho and initiated the first batch of confidential incentives with Merkl, where rewards are calculated based on encrypted balances. When depositing into eligible vaults, users can activate additional incentive options, granting viewing permissions for Merkl to read encrypted balances to calculate rewards without disclosing personal positions. This permission is enabled by default on the deposit interface, and deposits not shared with Merkl do not qualify for incentives.

Confidential vaults accumulate based on the user's confidential vault shares and can be claimed during the ongoing activity; existing public vaults with confidential access have rewards collectively obtained by the vault packaging contracts, which are distributed after the activity ends. Zama recommends claiming confidential activities at the end to reduce multiple on-chain fees. Taking the Flowdesk Confidential High Yield USDT vault on Morpho as an example, the related activity ended on October 12, and eligible depositors can now claim their rewards. Users need to check their earnings in Merkl using their wallet and complete the claim in the Zama app by connecting the same wallet; the amount received will not be publicly disclosed on-chain.
