Most exchanges quietly take a cut at every step — a fee here, a little slippage there, gas on top. Trade Koinos is built so the price you see is the price you get.
No maker fee, no taker fee, no spread markup. The contract charges nothing to place, fill, or cancel an order.
Koinos is feeless. Transactions run on mana that regenerates over time — and a mana sharer covers it, so you can trade with zero KOIN in your wallet.
A true limit orderbook — not an AMM curve. Your order fills at the exact price you set. No price impact, no sandwich, no surprises.
Makers and takers both trade at 0%. There's no protocol fee baked into the price and no hidden spread — the orderbook matches you at the resting order's price, exactly.
Koinos replaced gas with mana — a resource that recharges on its own. With the network's free mana sharer, your orders cost nothing to submit even if you hold no KOIN.
An AMM prices you along a bonding curve, so size moves the price against you and bots front-run the difference. An orderbook just fills your limit at the price you chose.
Funds are locked in the contract only while your order rests, and released the instant it fills or you cancel. The contract has no withdrawal or admin function — no one can touch your balance.
Depth-aware orderbook, live candlestick and volume charts built from real on-chain trades, limit and market orders with time-in-force. Everything you'd expect from a centralized exchange, with none of the custody.
