Fee Schedule
How Kyron's fees work
You always pay the price you see on the trade ticket. Fees come out of the share count you receive (on a buy) or the USDC you receive (on a sell), so a 30¢ ask is still a 30¢ ask — your share count is just slightly smaller.

Kyron's fee#
Kyron charges a variance-weighted fee on every trade. The formula is:
fee_usdc = trade_size_usdc × 0.02 × p × (1 − p)
The fee peaks at 0.500% when the price is 50¢ and tapers to zero at both 0¢ and 100¢. This protects long-shot bettors from disproportionate fees and keeps Kyron's effective rate materially below the routed-liquidity rate used on Sports and Crypto markets.
Aggregated-liquidity fee (when routed)#
When Kyron fills a trade through aggregated liquidity, an underlying venue fee can apply on top of Kyron's, following a similar variance-weighted shape:
liquidity_fee_usdc = shares × p × rate × p × (1 − p)
The rate depends on the market's category. Today the routed-liquidity rates are:
| Category | Rate | Peak effective |
|---|---|---|
| free | 0.00% | 0.000% |
| sports | 3.00% | 0.750% |
| crypto | 3.00% | 0.750% |
| finance | 0.00% | 0.000% |
| politics | 0.00% | 0.000% |
| tech | 0.00% | 0.000% |
| culture | 0.00% | 0.000% |
| economics | 0.00% | 0.000% |
| weather | 0.00% | 0.000% |
Categories that currently carry no routed-liquidity fee are shown at 0.00%. Kyron reflects the active aggregated-liquidity schedule here so the example math stays aligned with trade-ticket projections.
Worked examples#
Below is a $100 buy at each price point on a routed Sports market. Effective price is the USDC you actually pay per share after both fees come out.
| Quoted price | Shares | Effective price | Kyron fee | Liquidity fee |
|---|---|---|---|---|
| 1¢ | 9995.05 | 1.000¢ | $0.0198 | $0.0297 |
| 5¢ | 1995.25 | 5.012¢ | $0.0950 | $0.1424 |
| 10¢ | 995.50 | 10.045¢ | $0.1800 | $0.2695 |
| 20¢ | 496.01 | 20.161¢ | $0.3200 | $0.4785 |
| 30¢ | 329.84 | 30.318¢ | $0.4200 | $0.6274 |
| 50¢ | 197.51 | 50.631¢ | $0.5000 | $0.7462 |
| 70¢ | 141.36 | 70.741¢ | $0.4200 | $0.6274 |
| 90¢ | 110.61 | 90.406¢ | $0.1800 | $0.2695 |
| 99¢ | 100.96 | 99.049¢ | $0.0198 | $0.0297 |
Sells#
Routed-liquidity venues currently charge no taker fee on the sell side, so the only fee on a sell is Kyron's, computed off the gross USDC proceeds at the same variance-weighted rate. The user receives the gross proceeds minus Kyron's USDC skim.
