How to Protect Against Stablecoin Blowups

Dear Bankless nation,

Stablecoins are supposed to be stable, but they aren’t always. If you knew a depeg was incoming, what could you realistically do about it other than dumping your coins?

Y2K Finance is a protocol on Arbitrum that lets you bet on or hedge against these occasional “once in a lifetime” crypto events. It’s the kind of financial product you hope you don’t need but may be very happy you did use. Today, we take you under the hood of Y2K.

As we learned in 2022, stablecoins are not always so stable.

Throughout the year that shall not be named we had full-blown stablecoin collapses (UST), as well as numerous, large de-pegs (MIM and USDT).

Other than by shorting these assets on money markets like Aave, there was no real way for the market to protect themselves or profit from these de-peg events.

Enter Y2K Finance.

Y2K is a new Arbitrum-based protocol that enables users to speculate or hedge on stablecoin de-peggings. Sounds like something that could come in handy? If so, read on to learn how to use Y2K.

Y2K 101 🙃

Before we dive into how to use Y2K, let’s give an overview of how the protocol, known as Earthquake, works under the hood.

Y2K utilizes a model akin to catastrophe bonds in the insurance industry. These instruments let holders protect themselves against, or traders speculate on, and LPs to underwrite the risk of stablecoin de-pegs by depositing into one of two vaults: The “Hedge Vault” or the “Risk Vault.”

The Hedge Vault is intended for users who wish to purchase insurance for, or bet on, a given stablecoin de-pegging to or below a certain threshold known as the strike price. To do so, Hedge Vault depositors will pay premiums to depositors in the Risk Vault, the counterparty that underwrites the de-peg risk.

To see how strike prices and premiums are calculated, check out the Y2K docs.

If the price of a stablecoin does not reach the strike price (i.e. it doesn’t de-peg) during an epoch, the period of time in which coverage is being provided, then the Risk Vault will earn premiums at the expense of Hedge Vault. In this scenario, Risk Vault underwriters will also be able to reclaim their deposits.

Suppose the stablecoin depegs and it reaches (or falls below) the strike price. In this scenario, Risk Vault LPs will still earn premiums. However, depositors in the Hedge Vault will receive a payout in the form of the collateral inside of the Risk Vaults.

There’s a lot of minutiae under the hood of Earthquake. Once again, I’d highly recommend you read their docs and Medium posts. But the tldr is this:

  1. If you think (or fear) a stablecoin is going to de-peg, enter the Hedge Vault
  2. If you think a stablecoin will not de-peg, enter the Risk Vault

How To Enter Risk or Hedge Vaults

Now that we understand the basics, let’s walk through how to actually ape into the risk and hedge vaults. The process for entering both is similar, with users selecting the same parameters for each.

Let’s go through the steps for doing so below:

  1. Go to the Y2K user interface at
  2. Connect your browser wallet and select Arbitrum as your network.
  3. Scroll over and click on the “mint” tab. Once there, select “RISK” or “HEDGE” to begin the process of entering the Risk Vault or Hedge Vault respectively.
  4. Now, it’s time to select risk-parameters. First, select the stablecoin that you wish to either purchase (hedge) or underwrite (risk) insurance for. Y2K currently has active vaults for MIM, USDC, USDT, FRAX, and DAI. mint page
  1. Next, you’ll select a strike price. As discussed above, the Strike Price is the price at which the Risk Vault will payout to the Hedge Vault. As of writing, each supported stablecoin only has one offered strike price.
  2. The penultimate step to aping into either the Hedge or Risk Vault is to select an epoch, which refers to the period of time in which a user will either be purchasing or underwriting insurance for. Epochs currently last six days. It is important to note that your funds will not be accessible for the duration of this period. In the future depositors will be able access liquidity via Wildfire, an exchange for vault tokens that is being developed by the Y2K team.
  3. Finally, select an amount of ETH you wish to deposit into a vault, click “MINT” and confirm the transaction in your wallet. Upon confirmation, you’ll receive an ERC-1155 token representing your Hedge or Risk Vault deposit. Before you ape, be sure to take a look at the display of projected returns in the event of a de-peg or non de-peg, as well as the distribution of deposits between the hedge and risk vaults. Yes, the yields can be quite lucrative 👀.

  1. Upon completion of an epoch, head over to the “CLAIM” tab. If a de-peg did not occur, Risk Vault depositors will be able to redeem their assets and claim the premiums from the Hedge Vault. Should a de-peg have taken place during the epoch, Hedge Vault depositors will be able to claim the capital in the Risk Vault. In addition, Risk Vault depositors will still earn the premiums paid into the Hedge Vault.

We had previously made an error in this section with regards to the mechanics of the Hedge Vault which has since been corrected. Bankless regrets the error.

How To Farm $Y2K

There are opportunities for both hedgooors and riskooors to increase their returns by staking their vault tokens to earn additional rewards in Y2K, the protocol’s native governance token.

Let’s go through how to do so below:

  1. Click on the “FARM” tab on the Y2K UI.
  2. After doing so, head over to the “ELIGIBLE FARMS” tab to see which of your vault tokens are eligible to earn incentives. farming page
  1. Once you determine which vault tokens you’d like to stake, click on the yellow box and arrow icon.
  2. Now, select the amount of your vault tokens that you’d like to stake and click “DEPOSIT.” Before confirming the transaction, you’ll be prompted with the following disclaimer message regarding approvals.
Your MetaMask will also provide a similar disclaimer before you confirm a transaction. It is important to note that by accepting, you are only providing Y2K access to the vault tokens in your wallet. Y2K will not be able to access any NFTs other than the vault tokens.
  1. That’s it! You’ll now be able to earn Y2K rewards on top of premiums or payouts.


Y2K is a valuable new protocol that lets users hedge, speculate, and underwrite the risk of stablecoin de-peggings.

With the exception of opportunistic Hedge Vault depositors, we’re likely all hoping markets stabilize and downside volatility subsides.

But should there be more tumult on the horizon, you can now protect yourself (and profit from) stablecoin Armageddon with Y2K.
