Bootstrapping a vault whose balances are encrypted

Results

Data as of October 8, 2026; the campaign runs until November 5. APY is the live APY shown on the page at that time; the reward pool steps down daily and the APY moves with deposits.

The brief

Zama keeps on-chain balances private with fully homomorphic encryption, and Flowdesk curates the underlying USDT vault. Depositing a confidential asset means wrapping first and settling in batches — a few more steps than a regular vault, so the yield had to be clear and the flow had to be guided.

What Barker ran

1. 1

   The campaign page and comments opened a day early, an in-app notice went out 2 hours before start, and the campaign was pinned on the home page.

2. 2

   Barker's boost stacks on the vault's base yield and ZAMA token incentives; the reward pool steps down day by day, so earlier deposits earn a higher APY, with daily payouts.

3. 3

   Confidential deposits are tracked batch by batch — queued, settled and counted toward the boost, each step visible — so encrypted balances still get wallet-level attribution and daily payouts.

On-chain attribution

Every routed deposit is attributed wallet-by-wallet: deposits are verified on-chain, rewards stream through Merkle distributor contracts, and anti-sybil accounting uses time-weighted min(deposit, live balance). Partners get a live dashboard; users claim rewards directly from the contract. Barker never takes custody of principal.
