The official version of the FinNexus Protocol for Options (FPO) v1.0 hits the Ethereum mainnet on November 4th, 2020, followed shortly by its launch on the Wanchain mainnet. Both versions will be accessible at It will be the first DApp in the Wanchain ecosystem to deploy the unique “Dual DApp” strategy where, if you have both Wanmask and Metamask installed in your browser, you can interact with both blockchains from the same web page at the same time!

To use FPO v1.0, you must first move your tokens from FPO WildNet to FPO v1.0. We will release complete instructions about how to do so in the next few days, follow us on Twitter to make sure you don’t miss it.

Notice: FPO v1.0 contracts have not yet been audited. Your funds may be at risk. NEVER provide funds that you can’t afford to lose.

Change #1: Single, Multi Collateral Pool → Multiple, Single Collateral Pools

Single, Multi Collateral MASP Pool → Multiple, Single Collateral MASP Pools

Reasons for changing to single asset collateral pools:

  1. To simplify the liquidity providing process — With the new model, the type of collateral used to underwrite the options written from the liquidity pool and the asset withdrawn from the pool will be the same. Thus, liquidity providers can provide whatever asset they prefer (USDC or FNX) and know that they will receive that same asset, plus or minus the gains from providing liquidity, when they withdraw.
  2. Revamped benefits for FNX token holders — An individual pool exclusively for FNX collateral is necessary for the FNX ecosystem. It will offer unique opportunities available only for FNX holders to earn returns using their FNX tokens, promoting the long term value of the token.


  1. Benefits of the USDC MASP Pool — The USDC MASP pool takes advantage of USDC’s relatively lower volatility. Due to USDC’s low volatility, the USDC MASP pool’s MCR may be set lower than that of a more volatile asset, Which allows for a larger amount of options to be issued with a relatively lower value of collateral.
  2. Benefits of the FNX MASP Pool — While the FNX pool will generate a lower amount of options than the less volatile USDC pool, it will feature a higher level of rewards for pool users. Higher token lock up will also reduce FNX supply, putting upwards pressure on the token price.

Change #2: More Underlying Assets (LINK, MKR, SNX, & more to come)

FPO WildNet offered two underlying assets, BTC and ETH. Users could buy BTC and ETH puts and calls, with different strike prices and expirations according to their needs.

Since FPO is a universal options protocol, it is able to support a theoretically unlimited variety of underlying assets, as long as it has access to an on-chain price feed for that asset.

With the help of Chainlink, LINK, MKR, SNX will be available to FPO v1.0 users on the Ethereum mainnet.

Change #3: Sell-backs Disabled

Extrinsic value is also known as “time value” because the time left until the option contract expires is one of the primary factors affecting the option premium. Under normal circumstances, an option contract loses value as it approaches its expiration date because there is less time for the underlying assets’ prices to move favorably.

As the sell-back price is derived from the B-S model, it is inclusive of the time value (extrinsic value) of the options. While the exercising of options before expiration means the holders give up the remaining time value and realize the gains. However, unlike selling to other buyers in order books, when selling back to the pool, the pool acts as the sole counterparty, closes its position in a passive manner, and the options sold back cease to function. There should be no ‘time value’ left for these options sold back to the pool. So it is unfair to pool liquidity providers to include the time value in pricing. In other words, it is always more profitable for option holders to sell rather than exercise.

Therefore, the option sell-back function will be disabled in FPO v1.0, but option holders may still have the choice to exercise the options at their own discretion before expiration, provided it passes the 1-hour chill time.

FPO v1.0 Token Incentives

A comparison of the three options collateral pools soon to be available in FPO v1.0.

There will be 3 options collateral pools on FPO v1.0 live on both Ethereum and Wanchain. The 3 pools will work independently on-chain. The above FNX mining incentives on the Ethereum mainnet are expected to last for 30 days from 4th Nov. 2020. WAN mining incentives are expected to last for 15 days after its launch. Further incentives will be announced before the end of each period.

On 4th Nov. 2020, the incentives on Ethereum mainnet have been extended for another 30 days.

Note that the WildNet Mining incentives on Ethereum will end after FPO v1.0 is live on 4th Nov. 2020. Liquidity providers will have to withdraw their collateral from the Wildnet smart contract and re-stake their collateral into the FPO v1.0 smart contracts.
