Part I. About Y2K

Back in May, UST severely deviated from $1 and went into a death spiral with Luna, causing huge losses to both institutional and retail investors. The UST depeg gives crypto newbies their first lesson about extreme events. But how can you protect yourself from them? Here is our potential problem solver: Y2K Finance.


Y2K Finance is a suite of structured products designed for exotic peg derivatives, which will allow market participants the ability to robustly hedge or speculate on the risk of a particular pegged asset (or a basket of pegged assets). The main goal is to provide a market where buyers can hedge their exposure to depeg events, whilst others sell ‘insurance’ to bet against depeg events. Y2K has three main products:

  • Earthquake — A flagship product where users can use these vaults to hedge, speculate, and underwrite the volatility risk associated with various pegged assets.
  • Wildfire — An on-chain RFQ order book where users can trade Y2K risk tokens.
  • Tsunami — A Collateralized Debt Obligation (CDO) powered lending market for pegged assets with MEV-proof liquidations.

Currently, Y2K provides Earthquake only. Wildfire and Tsunami will be launched in the future.

How Earthquake Works

The core of Earthquake vaults is catastrophe bonds (CAT), a traditional financial product that pays the issuer when a predefined disaster risk is realized, such as a hurricane or an earthquake. In the case of Earthquake, it applies the CAT bond concept to de-peg events, liquid wrappers and, other derivative products in DeFi. Now, Y2K allows users to hedge against FRAX, USDC, USDT, MIM, and DAI de-pegging with weekly and monthly periods. Users can deposit ETH in one of two types of vaults: hedge vaults and risk vaults:

  • Hedge Vaults: Hedge vaults are for users who want to purchase ‘insurance’ on a depeg event by depositing ETH to corresponding hedge vaults. When users deposit into hedge vaults, it represents betting on a depeg event. If a depeg event happens, users who deposited in hedge vaults get the payoff.
  • Risk vaults: Risk vaults are for users who want to get exposure to the depeg risk market. They act as an underwriter of depeg insurance, which means they sell insurance and bet on not depegging. They collect a pro-rata share of the premiums from the hedge vault deposits.

After depositing into either hedge vaults or risk vaults, users mint an ERC-1155 Y2K token which represents their position in the vault.


For each pair of vaults, it has three properties:

  • Asset: The specific pegged asset the vault is trading. Now Y2K supports five stablecoins.
  • Epoch: The start and end date of the vault. Now Y2K supports weekly and monthly periods.
  • Strike: How far the price needs to deviate to trigger a liquidation event and hence a payout to the “Hedge” vault depositors. The Y2K team determines the appropriate strike by calculating the standard deviations, daily deviations, etc.


Users deposit into the vaults during the deposit period of each epoch. The funds are locked for the duration (one week or one month). During this time, the price of the stablecoin is monitored with Chainlink price oracle. If the strike prices for a given vault hits, the epoch will end and the vault will be closed. This will initiate a transfer of Risk vault deposits to the Hedge vault.

If the asset does not depeg:

  • Risk vault depositors receive a pro-rata share of Hedge vault deposits (premiums)
  • Hedge vault depositors transfer their paid-up premiums to the Risk vault depositors
No Depeg

If asset depegs:

  • Risk vault depositors receive a pro-rata share of Hedge vault deposits (premiums)
  • Risk vault depositors transfer their principal to Hedge vault depositors
  • Hedge vault depositors transfer their paid-up premiums to the Risk vault depositors
  • Hedge vault depositors receive a pro-rata share of Risk vault deposits


The protocol collects a 5% fee in the following scenarios:

  • 5% of Hedge Vault deposits
  • 5% of Risk Vault deposits upon a depeg event (no fee is charged if the peg is maintained)



Final Thoughts

  • Y2K is a PvP protocol based on pegged assets — stablecoins. The protocol acts as a casino charging a 5% fee as revenue. The revenue stream is relatively stable and profitable compared to other protocols because the protocol itself doesn’t take a risk to operate.
  • The high APY can attract users and form a flywheel effect attracting more liquidity for both vaults.
  • As the pool size of Y2K is relatively small compared with the size of major stablecoins like USDT and USDC, price manipulation on them is nearly impossible. However, as Y2K continues to develop, its stablecoin markets will extend to other exotic stablecoins like NEAR (USN), Arbitrum (VST), etc. Those exotic stablecoins involved a certain level of price manipulation risk as the market is quite small.
  • I am doubtful about the upcoming Wildfire product. Although it provides flexibility to users to enter or exit their position during the vault cycle and more ways to hedge their risk. From the document, we can see the model of the order book type secondary market is based on sellers and buyers placing orders. The problem with this model in this context is low liquidity and hence, a large spread between the bid and the ask. In addition, derivatives on stablecoins are exotic, it is difficult to price the fair value of it, you might see it as an option as it has a strike price and end date.
  • Although those derivatives can be used as insurance to hedge depeg risk, it is not easy to exactly hedge as the payoff depends on the strike price while stablecoin can completely depeg. If that is the case, users can still suffer from extreme depeg events.
  • Overall it is still an interesting protocol as it allows people to hedge stablecoins risk. It was built on Arbitrum which also enriches the Arbitrum DeFi ecosystem.
