Zero-SOL withdrawals
The relayer pays the network fee and takes a small cut. Holders pay less, and top tiers pay nothing.

Sepia
Move unseen.
Leave no trace.
Every payment lands on a fresh one-time address that nobody can link to your wallet. Share one link, receive SOL, USDC or any SPL token, withdraw without ever funding the address.
The problem
Your wallet is a public diary. Close it.
Share an address once and anyone can read your salary, your rent, your trades and every person who ever paid you. Flip the switch to see what the same week looks like through Sepia.

How it works
One link. A new address for every payment.
Sepia brings stealth addresses to Solana: the dual-key scheme Ethereum standardized as ERC-5564, rebuilt on ed25519 so every one-time address is a normal Solana account your wallet can sign for. There is no shared pool: funds go straight to addresses only you control.

The token
$SEPIA unlocks the privacy.
The product runs on fees, and every fee buys $SEPIA back from the market and burns it. Holders pay less, get more, and later run the network.
Holder tiers
More $SEPIA in your wallet means more payment links, recurring payments and team cashboxes.
Buyback & burn
All protocol fees buy $SEPIA on the market and burn it with a real SPL burn. Supply is fixed at 1B, so it only goes down.
Relayer staking
Phase 3: stake $SEPIA to run your own relayer and earn part of the fees. Misbehave and the stake is slashed.
Holder tiers
Hold more, hide more.
Your tier is read from your wallet balance. No staking lock-ups, no forms. Thresholds are published at launch.

FAQ
Questions people ask first
Is Sepia a mixer?
No. A mixer pools many people's funds in one shared pool and shuffles them. Sepia never holds or pools anyone's money: each payment goes straight to a one-time address that belongs to the recipient. Privacy comes from the addresses being unlinkable, not from mixing.
What can I receive?
SOL and USDC when the app launches, then any SPL token. The payer uses their normal wallet; the Sepia link tells it which one-time address to send to.
Who can see my payments?
Only the holder of your viewing key, which is you. You can choose to share it with an accountant or auditor, and they will see your Sepia payments without being able to move funds.
Why do I need $SEPIA?
You can use Sepia without it. Holding $SEPIA lowers or removes the relayer fee and unlocks more links, recurring payments and team cashboxes. All fees buy back and burn $SEPIA.
Where and when can I buy $SEPIA?
On pump.fun. When the bonding curve completes, trading moves to PumpSwap and the rest of Solana's DEXs. The mint address appears on this site and on @sepia_sol at launch. Any other address is not ours.
Is it audited?
The scheme is the same dual-key construction behind ERC-5564 and Monero, moved to ed25519. The Sepia program and relayer will be audited before large amounts flow through them; the audit is a gate in the roadmap.
Why Solana?
A fresh address per payment only works if it costs almost nothing, and on Solana it does. Every transaction can name a separate fee payer, so the relayer covers your withdrawal natively, without wrapper contracts. And Solana is where people already pay each other in USDC and memecoins every day, all of it readable on Solscan.
