Your address reads empty
Deposit and the balance leaves your account for the pool program. Anyone reading your address sees a wallet with nothing in it.
Built on Solana · SOL and SPL tokensHold everything.
Hold everything.
Show nothing.
Deposit into the Exovia pool program and the balance leaves your address for a pool shared with everyone else's. Send it on with a proof that names no sender, or lock it behind a passphrase only you know. From the outside it reads as ordinary settlement.

Two vaults
Pick the kind of quiet you need
One breaks the link between who paid and who was paid. The other keeps what you hold off the record. They are separate vaults and you can use both.
Shielded Vault Anonymous transfers | Guarded Vault Hidden holdings | |
|---|---|---|
| What it is for | Paying someone without naming yourself | Holding a balance nobody can read |
| How privacy is won | A zero-knowledge proof stands in for your identity | Funds sit in the pool program; your address reads zero |
| What the chain shows | The depositor is never named | The depositor is visible; the amount is not |
| Crowd to hide in | Grows with every deposit of the same size | None — this one hides the amount, not the sender |
| Exit without a fee balance | through a relayer | — |
| Send inside the vault | — | to any address |
| If your key leaks | — | Funds hold — the passphrase is a second lock |
| Getting funds out | Present the ticket, prove it, withdraw | Sign, then enter the passphrase |
| Open Shielded Vault | Open Guarded Vault |
How it works
Three moves, start to end
- 01
Deposit
Send SOL or any SPL token to the vault. It lands inside the pool program as an internal balance, and only a commitment — a one-way fingerprint — is written on chain. No amount, no name.
- 02
Let it sit
Keep your ticket somewhere safe. Every deposit of the same size that arrives after yours widens the crowd you are standing in, and narrowing it back down gets harder by the day.
- 03
Withdraw
Build a proof from the ticket and withdraw to an address that has never touched the first one. What the chain records is a pool settlement, and nothing points back.
Architecture
What the design actually buys you
One shared pool
Every deposit joins the same program-owned pool. Yours is not a separate box with your name on it — it is one entry among all of them.
SOL and any SPL token
Native SOL, stablecoins, or a token minted this morning. There is no list of approved mints to be on.
Move funds inside
Send a balance to another address without either side leaving the vault, so nothing about the pair is written down.
Proofs, not passwords
A withdrawal is settled against a zero-knowledge proof. The program learns that a valid deposit exists and nothing else about which one.
Looks like plain settlement
Withdrawals leave the same trace as any other pool payout — there is no distinctive shape for an observer to filter on.
Arrive without fees
A relayer pays the network fee and takes 0.30% out of the withdrawal, so a fresh address never has to be funded first.
A second lock
A passphrase-derived guardian key sits over the Guarded Vault. A stolen private key on its own moves nothing.
Nobody holds a master key
No admin, no upgrade path, no pause switch. A spent deposit is recorded once and can never be spent twice.
Your funds. Your business.
Connect a Solana wallet and look around. Nothing moves until the vault programs are live.
