Trade on an order book,
fully on-chain.
Every fill, a price you chose. Iter routes, matches and settles in the open — self-custody the whole way.

One book. Both problems solved.
Settlement, by limit orders. Inventory, by the pool. Together, a real market.
Settlement: solved by limit orders
Every trade is a limit order on one on-chain book: you name your price, the book matches you with the best one available. The price comes from people actually trading, not from a formula, and nothing fills at a price you didn't set.
Inventory: solved by the pool
Anyone can deposit into the pool. Deposits fill the other side of trades, only inside the price range each depositor chose, and earn a fee every time. The assets come from everyone, not from a market-making firm.
Together: an organic market
Orders and pool deposits meet on the same book, so prices come from real trades, averaged over ten minutes so nobody can rig a moment. Real prices, real liquidity, no middleman.
Every fill, at a price you chose. On-chain to check.
A large trade that loses up to 66% of its value to price impact on Uniswap v2 fills near its quoted price here. If the book can't fill you, your money comes back. No fake prices.
A sandwich attack that takes $500,000 from one trade on Uniswap v2 gets $2.55 here. After paying gas, the attacker loses money on every trade size.
When the market moves 25%, Uniswap and Curve's own impermanent loss wipes out their fee income and goes net negative. Iter's loss is capped at the price the LP quoted, so its LPs stay profitable no matter how far the market moves.

LP loss when the market moves
Impermanent loss — how far a position ends up behind simply holding the two assets, once the price has moved — at Iter's widest tolerance vs. passive AMM liquidity.

Iter LPs still profit after the market moves 25%
A pool quotes a stale price until an arbitrageur takes the gap, wiping out Uniswap's and Curve's fees and leaving their LPs negative, while an Iter LP sets their own price — so the worst case is the price they chose, and profit holds even at +100%. CEX makers are counted at gross with inventory cost as zero, and the top tier still trails Iter's thinnest net.

Compare with data.
Every number on this page comes from the same simulation we use to build the product, not a highlight reel: every chart plots the full data grid, including the regimes where Iter doesn't win. We once caught a pricing bug of our own with it, one that was quietly losing money on the safest position, before it touched a dollar, and published that too. We do research in the open, fair and square.
How the fee is actually computedThese are the same three formulas behind the LP charts above, run on your own number instead of a fixed $1M example. Type in how much USDC you'd provide as liquidity and every figure below, and the chart, recomputes live — using the exact rates from the simulation, not rounded estimates.
This is not a yearly or daily rate. Every number below answers one question: once trading volume equal to your own liquidity has matched against it, one time, what fee did you earn? How often that happens in a real day depends on the pair and the market — that turnover rate isn't modeled here. If your liquidity gets matched twice a day, earn this amount twice a day; if it sits untraded, you earn nothing that day.
fee rate × your liquidity
0.30% flat
per matched turn, not per year
fee rate × your liquidity
0.04% flat
per matched turn, not per year
(spread margin + trader's taker fee) × your liquidity — you pay no fee

Fee earned per matched turn, vs. liquidity provided
- Uniswap v2 / v3
- Curve
- Iter
Every line is a straight fee-rate-times-liquidity line; steeper means more fee per dollar deposited. The dashed marker is your current number above.
Liquidity provided (USDC)
Uniswap and Curve charge a protocol-fixed rate, same for every LP, every pair, regardless of how they quote. Iter's LP pays no fee at all — they earn the spread they quoted themselves, plus the fee the trader's own membership tier pays; the rate above is the top tolerance tier on a thin book, the same one behind the “Iter, thin market” row on the charts above. This assumes your liquidity gets matched dollar-for-dollar — real turnover varies by pair and venue, and it's the same simplifying assumption the net-of-price-risk chart above already uses. Open the LP charts above for every tier and book depth, not just this one.
A price that survives someone trying to move it.
Every trade here settles at a price averaged over real trading, not whatever happened in the last block. That price is a primitive other products can build on, not just a number shown to traders.
Lending
A lending market's liquidations are only as safe as the price that triggers them. A flash loan can move a single block's price; it can't move a ten-minute average.
Futures
Already live: Iter's own perpetuals read their mark price straight from this same book, not a separate oracle.
Options
An option settles against whatever price is quoted at expiry. That price should survive someone trying to move it in the last block — this one does.
Stablecoins
A peg holds only as long as the price watching it can't be cheaply lied to. Read from a book that's already built to resist that.
Every product above needs the same thing: a price nobody can cheaply move. This book already is one.
Put an agent on a mandate, not on your wallet.
Research can be probabilistic. Risk cannot. Iter Agent Desk keeps models behind explicit limits, approvals, and a reconstructable execution record.
Limits enforced before execution
Pairs, size, exposure, slippage, cadence, loss and expiry.
A track record with receipts
Every live result links to its strategy version, proposal, transaction, fill, fees and cash flows.
Pause stays with the owner
The agent cannot widen policy, withdraw capital, or hide a rejected action.
Test a frozen strategy against live Iter market data. No wallet authority and no assets at risk.
Whichever seat you take, it’s the same wheel to earn.
Every payout on Iter traces back to one event: someone got filled. Nothing here is funded by issuing tokens against a promise. Pick a seat and follow it round.
- You give
- One taker fee per fill — the same rate on the order book and in the pool, so there is no cheaper door.
- You get
- $ITER rewards on what you trade, and tighter spreads as the fee you paid funds the depth sitting in front of you.
The fee is charged once, on the quote side, and it is the only thing you pay.
Nothing to trust. Everything to verify.
Settlement is verifiable on-chain. The paper, the simulation, and the contracts are public. No token, no pitch: an argument to steal from, not a product to buy.
