Deribit Derivatives Exchange fees are among the lowest fees available and operates a maker-taker model. Futures orders which provide liquidity receive a rebate of 0.02%. Orders that take liquidity are charged a small fee of only 0.05%. The fee is calculated as a percentage of the underlying asset of the contract.

Maker Rebate: 0.02%
Taker Fee: 0.05%

0.04% of underlying or 0.0004 BTC/option contract

Fees can never be higher than 20% of the price of the option. For example if an option is traded at 0.0001 BTC, the taker fee will be 0.00002 BTC (instead of 0.0004 BTC), thus 20% of 0.0001 BTC.

Delivery (settlement at expiration)
For deliveries (expiration) half the fees of taker orders are charged.  Eg: 0.025% for Futures, and 0.02% for Options, where for options the fee can never be more than 20% of the value of the option.

Fees for Liquidation trades.
Liquidations are charged a higher fee than normal. Fees are raised with 0.1% of underlying contractsize. The surplus fees of liquidations will automatically fund the insurance fund.
Futures liquidations trades:
0.15% taker fee,  0.1% goes to the insurance fund.
0.08% maker fee, 0.1% goes to the insurance fund.

Options liquidations trades: 0.14% of underlying or 0.0014BTC/options contract, 0.1% of underlying or 0.001BTC per contract goes to the insurance fund.
So the higher fees of liquidation trades are the income for the insurance fund.
