Filled.
Not seen.
Trade size without showing your hand. Orders go in sealed, nobody sees side, size or price, and every match fills at one fair price. No front-running. No sandwiches. No price impact.
On a normal DEX
- Your swap sits in the public mempool
- Bots buy in front of you and sell right after
- Big orders slide down the AMM curve
- Whale wallets get tracked and copy-traded
On Silent Fill
- Orders are sealed hashes until the batch closes
- Nothing to front-run: everyone gets the same price
- Fills at the oracle midpoint, not along a curve
- Bigger side fills pro-rata; leftovers just unlock
How a batch works
Whisper
Post a sealed order with a small refundable bond. On-chain it’s just a hash: no side, no size, no price.
60 secondsUnseal
The app reveals your order for you. The window is closed to new orders, so there’s nobody left to front-run.
30 secondsThe Fill
Every matching buy and sell settles at one oracle midpoint price. If the price feed breaks, the batch cancels and funds unlock.
one transactionSealed orders
Commit-reveal keeps your intent hidden while orders are being collected.
One fair price
Every fill in a batch clears at the same price. No one gets a better deal for being faster.
Funds never trapped
Bad oracle? The batch cancels and everything unlocks. Withdraw free balance any time.
Your keys
Non-custodial smart contracts. You sign every action from your own wallet.
FAQ
What is a dark pool?
A venue where orders are hidden until they trade. Big traders use them so the market can’t react to their order before it fills.
What’s the bond for?
A small deposit locked when you Whisper and returned when you Unseal. It stops people from posting orders they never intend to reveal.
What price do I get?
The oracle midpoint at the end of the batch, as long as it’s within your limit. If it isn’t, your order simply doesn’t fill and your funds unlock.
Is this real money?
No. Silent Fill is on Robinhood Chain testnet with test tokens from the built-in faucet. It hasn’t been audited yet.
