Paradex facilitates record $16M ETH options trade at lower cost than Deribit

A single ETH options trade worth $15.76 million just settled on Paradex, a decentralized derivatives exchange built on Starknet, for a total premium of $45,220. For context, that’s roughly 0.29% of the notional value, and the platform claims the execution cost came in cheaper than what traders would have paid on Deribit, the reigning king of centralized crypto options.

Paradigm’s RFQ engine changes the math

The record trade followed Paradex’s integration of Paradigm’s request-for-quote liquidity network on September 15, 2026. RFQ systems work differently from traditional order books: instead of posting limit orders and hoping someone bites, a trader requests a price from multiple market makers simultaneously, who then compete to fill the order. That mechanism is particularly useful for large trades where slippage on a regular order book would eat into returns. Paradigm’s RFQ network typically supports trades that are 100 times larger and more competitively priced than standard Deribit flows, according to the platform.

The results showed up almost immediately. Daily notional trading volumes on Paradex climbed to between $14.5 million and $17.6 million shortly after the RFQ launch. Open interest, the total value of outstanding derivatives contracts, surged 2.6 times to $202 million.

Before going live publicly, Paradex ran a closed beta for the RFQ functionality. During that testing phase, the platform generated over $50 million in options notional volume, including trades totaling $30 million across 46 blocks.

Why Deribit should be paying attention

Paradex offers zero fees for retail traders. It uses ZK-based encryption on Starknet for trade privacy, meaning participants can execute without broadcasting their positions to the entire blockchain before settlement. By plugging into Paradigm’s network, it’s accessing the same institutional liquidity layer that sophisticated traders already use.

The exchange has also introduced European-style ETH options with cash settlement via time-weighted average price, or TWAP. European options can only be exercised at expiration, unlike American-style options that can be exercised anytime. Cash settlement through TWAP smooths out the price reference over a window rather than using a single snapshot, reducing the risk of manipulation at the settlement moment.

Paradex also operates with unified margin across its trading products, meaning collateral posted for one position can support others.

What this means for DeFi derivatives

Paradex’s approach of partnering with an established off-chain liquidity network rather than trying to bootstrap liquidity natively sidesteps the cold-start problem that has killed many DeFi options protocols before they could gain traction.

The $202 million in open interest, while modest compared to Deribit’s multi-billion-dollar figures, represents a proof of concept. Institutional traders are demonstrably willing to execute large positions on decentralized infrastructure when the execution quality and cost structure justify it.
