Why It Costs So Little

A venue that holds no inventory and quotes no price has nothing to charge you a spread for.

No Spread

You fill at the pool midpoint, before the pool fee.

No Price Impact

A batch fills everyone at one price, whatever the size.

No Fill, No Fee

Unfilled size and voided batches pay nothing.

No Surprises

Each order keeps the fee in force when it was revealed.

Fee Questions

How the fee is charged, where it goes and how staking pays out.

Both, 0.10 % each on the USDG value that crossed. A buyer's locked USDG includes a fee budget; a seller pays out of the proceeds.

In USDG. Each settlement pays stakers their share of its fees, and collecting a batch's forfeited bonds does the same. Claiming moves them into your vault balance, from where you can withdraw.

No. Stake and unstake whenever you like. Rewards go to whoever is staked when a settlement pays out, so a stake placed just before a big settlement earns its share of it.

If an order is not revealed, its 1 USDG bond is split like a fee once the batch's forfeits are collected: 80 % to stakers, 20 % to the treasury, or all of it to the treasury while nothing is staked.

Only up to 0.50 %, and only 48 hours after being queued. Orders already in a book keep the fee they were revealed with.
