dreamDEX pioneers a yield-subsidized fee model that offers zero trading fees while maintaining protocol sustainability and rewarding liquidity providers.
Trading Fees
dreamDEX charges 0% maker and taker fees. Unlike traditional exchanges that extract value from every trade, dreamDEX monetizes the time-value of collateral.
| Fee Type | Rate |
|---|---|
| Maker Fee | 0% |
| Taker Fee | 0% |
Gas Fees
On-chain actions consume Somnia network gas. dreamDEX pays the gas for:
- placing and cancelling orders on the SOMI ↔ USDso and USDC.e ↔ USDso pairs,
- creating your trading account and withdrawals from it,
- the automatic transactions that keep the account running: moving native token to its signing key for gas, buying SOMI after a deposit, moving funds to a new account, and adding your login wallet as an owner.
Everything else, including stop orders, Event Contracts, perps, lending and other spot pairs, is paid from your account's native balance (SOMI on mainnet, STT on Shannon testnet). If sponsorship is briefly unavailable, a sponsored order is not sent at all, while a withdrawal falls back to paying its own gas.
Gas use and network prices vary, so fixed per-action estimates are not published here. A deposit from your personal wallet is a transaction on the chain you deposit from: from another chain it needs that chain's gas token in the personal wallet, which also pays LayerZero's messaging fee, and from Somnia it needs the network's native token (SOMI on mainnet, STT on Shannon testnet).
Maker Rewards: Collateral Yield
Makers do not receive traditional "rebates." Instead, they earn Collateral Yield on their resting liquidity.
When you place a maker limit order, your margin remains in your control on-chain while being automatically eligible for yield generation. This rewards market makers for providing book depth and maintaining tight spreads.
How it Works
The protocol provides yield to all open interest on the books. To encourage liquidity where it's needed most:
- Proximity Weighting: Orders closer to the mid-price receive a higher weight in the yield distribution.
- Continuous Accrual: Yield is earned for as long as the order remains open on the book.
- Payment: Yield is paid out in USDso to the maker's wallet.
For a technical breakdown of how yield is calculated and distributed, see the Collateral Yield Algorithm.
