SHROUD · DOSSIER 001 · CONFIDENTIAL

PAY ANYONE.
ON A SCHEDULE.
SEEN BY NOBODY.

Shroud is the first recurring private payment layer on Solana. Shield once. Stream forever. The schedule, the amount, and the payer remain invisible — settlement stays publicly verifiable.

§ 1 · The observation

Every payroll,
every subscription,
every stipend —
leaks who, how much, and how often.

Streaming protocols on Solana publish a transaction to base layer for every tick. A DAO that pays its contributors weekly publishes its contributor list, their cadence, and their rate — forever, publicly, immutably.

Existing privacy tools stop at the single transfer. No shielded pool on Solana lets you schedule private payments without leaking the schedule itself.

Shroud fixes that.

§ 2 · Mechanism
01
SHIELD

You fund a per-stream burner once. It deposits into Loyal's vault and delegates to MagicBlock's Private Ephemeral Rollup.

02
DELEGATE

Account ownership moves into Intel TDX. From here, every balance update is invisible to external observers.

03
TICK

Our scheduler executes transferToUsernameDeposit on cadence — inside the TEE. No base-layer footprint. No trace.

04
UNSHIELD

On completion or cancel, state commits back to base. Remaining funds refund to your wallet. One in, one out.

§ 3 · Field use

Who moves money
through a shroud?

DAOs paying contributors

Stop publishing your full contributor list on-chain every Friday.

Creators on retainer

Monthly payments to your editor, translator, ghostwriter — without doxxing them.

Private treasuries

Fund a public persona from an unlinked shielded pool.

Ghost subscriptions

Tip or subscribe to a creator by @handle only. No wallet ever touches wallet.

§ 4 · The public ledger

What chain watchers see.

A single shield transaction. Then silence — for days, weeks, months. Then a single unshield. That's the entire on-chain trace of a 12-month private payroll.
