Gasless withdrawals
Relayer withdrawals cost a small fee. Holders pay less, and top tiers pay nothing.

Sepia
Get paid.
Leave no trace.
Every payment lands on a fresh one-time address that nobody can link to your wallet. Share one link, receive in ETH, USDC or any Pons token, withdraw without gas.
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 is built on ERC-5564, the Ethereum standard for stealth addresses. It runs on any EVM chain, Robinhood Chain included. 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. Supply on Pons is fixed, 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 contract 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?
ETH and USDC at launch of the app, then any token traded on Pons. 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 Pons, the main launchpad on Robinhood Chain. The contract address appears on this site and on @sepia_rbh at launch. Any other address is not ours.
Is it audited?
Stealth addresses follow a public Ethereum standard. The Sepia relayer and announcement contracts will be audited before large amounts flow through them; the audit is a gate in the roadmap.
Why Robinhood Chain?
It is an Ethereum layer 2 built on Arbitrum Orbit, so ERC-5564 works as is, fees are low, and the chain already has the busiest memecoin launchpad scene. Its users trade in public; Sepia gives them a private way to get paid.
