On-chain options premiums are cheap. Liquidity is part of the story, but the root cause is not simply "nobody is trading." Instead, liquidity is split into many tiny pieces. A low price does not always mean a good deal. It may mean the contract you are looking at has almost no counterparties.
Why Low Liquidity Makes On-Chain Options Look Cheap
In traditional finance and centralized exchanges such as Deribit, all trading demand goes into one unified order book. On-chain options are different. The market is split into many small pools by strike price and expiry date, so each pool has very thin depth.
This creates a situation that looks good for buyers. When an options contract has very poor liquidity, market makers or liquidity providers often protect themselves. Instead of setting a high price to take the other side, they usually quote a very wide bid-ask spread. The "ask" price you see as a buyer may look low, but behind that price, you may struggle to find anyone to take your position when you want to close it.
Platforms Are Trying to Fix This, But It Is Not Easy
As early as 2016, on-chain options tried an order book model. However, on-chain market making costs were too high, and market makers found it hard to update quotes in real time. Later, the market moved to AMM (automated market maker) models, but pricing was easily exploited by arbitrageurs, and liquidity providers often lost money.
The current mainstream approach is "off-chain order book + on-chain settlement." Leading protocols like Derive now account for about 80% of on-chain options trading volume. Yet the entire on-chain options market is only about 0.2% of perpetual contract trading volume. That size shows on-chain options are still a niche market.
The Real Risk Behind "Cheap": The Liquidity Time Trap
If you buy a deep out-of-the-money option cheaply, or a far-dated option with very poor liquidity, the biggest risk is not price. It is time. Options have time value. As expiration approaches, that value decays faster. If poor liquidity stops you from closing the position, or forces you to sell far below your mental price, the "cheap" option turns into a real loss.
How to Check Liquidity Before You Trade
Before placing an order, check the contract's bid-ask spread and recent trade history on the options trading page. If the spread is very wide (for example, bid 1 USDT and ask 5 USDT), or if trading volume in the past 24 hours is extremely low, the "cheap price" you see is only a surface quote, not a fair market price.
