Vault Bidder (Option Buyer)

17min

Options Buyers purchase options to meet their speculative or hedging needs.

  • Speculators

High volatility is one of the key characteristics of long-tail assets. If speculators long or short on such assets by holding perpetual futures, they are highly likely to be liquidated, even with 5x leverage. However, if they use options to long or short on these assets, they will be exempt from liquidation risk. By buying out-of-the-money options, they can leverage their positions up tp 1,000x.

  • Hedgers

Options allow traders to hedge non-linear risks. Typus will integrate AMM Swap and lending protocols to meet the long-term and stable demand for options.



Covered Call Buyer

A Covered Call vault bidder is a covered call buyer. The buyer needs to bid the option when the vault is auctioned and pay premium (depositor's reward) either in underlying tokens (such as $SUI) or stablecoins (such as $USDC) after an auction ends.

If the buyer decides to execute the contract as the call option expires, the underlying asset deposited by the seller will be transferred to the buyer, that is, cash-settled in tokens.

Example

You pay 0.0625 SUI to buy 1 SUI call option.

  • Duration: 7 days
  • Current market price: 1 SUI = 10 USDC
  • Strike price: 1 SUI = 15 USDC
  • Contract Size: 1 SUI Call Option
  • Premium: The seller gets 0.0625 SUI from you before vault settlement

Case 1: When Settle Price > Strike Price, you may gain

If the price of SUI rises strongly to 20 USDC when the call expires, you have the right to execute the call. At this time, you get 0.25 SUI token from the seller. The amount is equal to the difference between the market price and the strike price at expiry. 

  • Market price at expiry: 1 SUI = 20 USDC
  • Strike price: 1 SUI = 15 USDC -> executed by you
  • Vault Settlement: You get [ (20 - 15) / 20 ] =  0.25 SUI from the seller
  • Net PNL in SUI:
    • You get 0.1875 SUI ( 0.25 SU - 0.0625 SUI = 0.1875 SUI )
    • The seller loses 0.1875 SUI

If the price of SUI rises slightly to 16 USDC when the call expires, you have the right to execute the call. At this time, you get 0.0625 SUI token from the seller. The amount is equal to the difference between the market price and the strike price at expiry. 

  • Market price at expiry: 1 SUI = 16 USDC
  • Strike price: 1 SUI = 15 USDC -> executed by you
  • Vault Settlement: You get [ (16 - 15) / 16 ] =  0.0625 SUI from the seller
  • Net PNL in SUI:
    • You are breakeven ( 0.0625 SUI - 0.0625 SUI = 0 SUI )
    • The seller is breakeven too

Case 2: When Settle Price ≦ Strike Price, you lose

If the price of SUI stays below 15 USDC when the call expires, you will not execute the call.

  • Market price at expiry: 1 SUI ≦ 15 USDC
  • Strike price: 1 SUI = 15 USDC -> not executed by you
  • Vault Settlement: The seller doesn’t need to transfer SUI to you
  • Net PNL in SUI:
    • You lose 0.0625 SUI
    • The seller gets 0.0625 SUI
