Using the Exchange
Fee Structure
Transparency is a core value at Open Mandi. We believe you should know exactly what you're paying, why you're paying it, and where that money goes. Here's a complete breakdown of every fee on the platform.
Our Fee Philosophy
Fees on Open Mandi serve two purposes: they sustain the platform and they teach you how fees work on real exchanges. Every fee collected is visible on the Transparency Dashboard, so you can see exactly how much revenue the exchange generates.
Trading Fees (Futures)
When you trade gold or silver futures, you pay a small fee based on the trade value. Fees differ depending on whether you're a maker or a taker:
- Maker — you place a limit order that adds liquidity to the order book (your order sits on the book waiting to be matched)
- Taker — you place an order that immediately matches with an existing order, removing liquidity from the book
| Fee Type | Rate | Description |
|---|---|---|
| Maker Fee | 0.02% | Paid when your limit order is filled by another trader |
| Taker Fee | 0.05% | Paid when you fill an existing order on the book |
Makers get lower fees because they provide liquidity, which makes the market healthier for everyone.
Exchange Fees (USDT/USDC)
The same maker/taker model applies to the stablecoin exchange:
| Fee Type | Rate | Description |
|---|---|---|
| Maker Fee | 0.01% | Limit orders that add liquidity to the USDT/USDC book |
| Taker Fee | 0.03% | Orders that immediately match on the USDT/USDC book |
Exchange fees are slightly lower than futures trading fees because stablecoin swaps are simpler transactions.
Deposit Fees
No fees. Deposits are free on Open Mandi. You may pay network transaction fees (gas fees) on the blockchain side, but the platform itself does not charge for deposits.
Withdrawal Fees
A small flat fee is charged to cover blockchain transaction costs:
| Currency | Fee |
|---|---|
| USDT | $0.10 |
| USDC | $0.10 |
