Glass boxes leak.
On chain, a fund shows everything. Every position and every holder's balance is public, so anyone can trade ahead of the manager or read what each client owns.

A blind trust, turned inside out
A city of machines, no people. A rule set sealed for Arcium's encrypted network decides; a Solana program holds the pool and enforces the walls.

On chain, a fund shows everything. Every position and every holder's balance is public, so anyone can trade ahead of the manager or read what each client owns.
Off chain, a fund shows nothing. The strategy stays private because a person holds the money, and you are asked to trust that person with both.
The rule set is encrypted for Arcium. Its nodes compute the next order without seeing the rules, and the program accepts only orders carrying their signature.
The limits are code anyone can read. No instruction pays the pool to an address. Trades go through Orca or Jupiter, at most 20% of the pool a day and 0.5% from the oracle price.
How the machine runs
Public, then sealed
USDC goes into the USDC vault. Shares are minted at the pool's value per share, priced by Pyth, and moved in the same instruction into your pending confidential balance.
What does the chain see when you deposit?
... at the USDC price on Jupiter
25,000.00 USDC in, 24,975.00 shares minted
Both numbers sit in the deposit instruction for anyone to read. The 0.1% deposit fee stays in the pool. Seconds later the shares are in your confidential balance, and the public balance reads zero.
Sixty-four bytes of twisted ElGamal over ristretto255, the construction of a Token-2022 confidential balance. Every encryption draws fresh randomness, so the same balance never prints the same way twice.
The manager
The rule set is encrypted for Arcium's network, a multi-party computation on Solana. Its inputs are split across the nodes, so no single machine, ours included, holds them in the clear. What comes out is an order, and the order is public.
Blackthorn, Arcium's encrypted AI inference, is not open yet. Until it is, the manager is an encrypted rule set: target weights and a band, hidden; the logic that compares them, public.

Under the Office of Government Ethics rules, a qualified blind trust hides the trustee's choices from the official who owns the assets. UNLIT keeps the manager's rules from everyone and shows everyone what the manager did.

In UNLITOnly the holder's key. The deposit itself is public; the balance after it is not.
