Fee policy
KAIRO fees
Each KAIRO product has its own fee. Nothing is hidden, nothing is charged on deposits, withdrawals or claims, and Arc network gas is always separate. The section below covers KAIRO Markets; every other product follows further down.
KAIRO Markets
Current trading fee
1.50%
Showing the deployed V1 configuration; live values load once an Arc node responds.
1.00%
Protocol
Funds development, infrastructure and operations.
0.25%
Market creator
Accrues to the wallet that created the market.
0.25%
Liquidity
Stays in the market pool, deepening the market.
100 + 25 + 25 = 150 basis points. The contract enforces this equality, so the split can never silently exceed the advertised total.
Fee examples
| Trade size | Total fee | Protocol | Creator | Liquidity |
|---|---|---|---|---|
| 10 USDC | 0.1500 USDC | 0.1000 USDC | 0.0250 USDC | 0.0250 USDC |
| 100 USDC | 1.5000 USDC | 1.0000 USDC | 0.2500 USDC | 0.2500 USDC |
| 1000 USDC | 15.0000 USDC | 10.0000 USDC | 2.5000 USDC | 2.5000 USDC |
| 10000 USDC | 150.0000 USDC | 100.0000 USDC | 25.0000 USDC | 25.0000 USDC |
A 100 USDC trade pays 1.50 USDC in total: 1.00 to the protocol, 0.25 to the creator and 0.25 to liquidity. USDC has 6 decimals, so amounts are rounded at the sixth decimal place inside the contracts.
Fees by product
Fee models are never shared between products. Where a fee is charged by an external venue or pool rather than by KAIRO, that is stated.
| Product | KAIRO fee | Detail |
|---|---|---|
| KAIRO Markets | 1.50% | 1.00% protocol, 0.25% market creator, 0.25% retained in market liquidity. Read live from the protocol configuration contract. |
| Up or Down | 1.50% | Same contracts and same fee split as KAIRO Markets. |
| KAIRO Launch | 1.50% | On curve buys and sells: 1.00% treasury, 0.25% token creator, 0.25% graduation reserve. Launching a token itself costs gas only. |
| KAIRO Swap | 0.25% | Charged on swaps routed through KAIRO's own router. The pools you route through charge their own fee, which is already included in the quote you see. |
| KAIRO Perps | 0.03% | Builder fee on fills. The trading venue charges its own taker and maker fees, and funding is exchanged between longs and shorts — neither is a KAIRO fee. |
| Create Token | 49 USDC | One-off creation fee paid in USDC before deployment. No fee on the token's later trading, though a token can carry its own optional tax set by its creator. |
| Create Market | No fee | Creation takes a refundable creation bond and your initial liquidity, not a fee. Both are shown in the creation panel before you sign. |
Trading fees
Charged on applicable buys and sells, calculated on the trade notional and deducted at execution. The trade panel shows the exact split before you sign, and the on-chain Trade event records each component.
Creator fees
0.25% of applicable volume accrues to the market's creator and is claimed from the portfolio page in a separate transaction. Earnings depend entirely on real trading and are never guaranteed.
Liquidity allocation
0.25% is retained inside the market's pool rather than paid out. This deepens the market over time and benefits everyone trading it, including liquidity providers.
Network fees
Arc charges its own transaction cost, paid in USDC, for every approval, trade, creation, proposal and claim. That cost goes to the network, not to the protocol, and varies with network conditions.
Fee changes
Fee parameters live in the protocol configuration contract and can be changed by its owner for future activity. Any change is visible on chain and reflected on this page immediately, because these numbers are read from the contract.
What is never charged
No deposit fee, no withdrawal fee, no claim fee, no subscription and no spread added by the interface. The only interface-visible cost is the 1.50% trading fee.
