Refunds issued for impacted Platypus, Echidna, Vector Depositors
Refunds for depositors in Yield Yak’s Platypus, Echidna, and Vector Pools which were impacted by the Platypus exploit have been delivered via airdrop
Impacted depositors have been distributed their share in the asset they originally deposited. Refunds are worth ~52% of the value of their initial deposit.
Yield Yak has covered the gas costs and slippage to facilitate distributing refunds in the original asset deposited.
As a goodwill gesture for the delays, users have been airdropped 1 $yyAVAX
Any future refunds from the three protocols will be redistributed to users.
Technical Explanation On-chain accounting is done using YRT balances which are 'shares' of a given pool. These pools lost the underlying deposit assets due to an exploit of Platypus' protocol, meaning each YRT 'share' became unbacked. The issue affected three sets of pools, Platypus, Echidna, and Vector (16 pools in total).
We received refunds from all three platforms, and may receive additional refunds in the future pending Platypus' recovery attempts.
Because YRT are transferable, we have taken a historical snapshot for each affected pool. Affected YRT are no longer worth anything and can be burned or transferred without affecting future refunds.
In order to compensate each group of users, we had to make two conversions:
1. Convert YRT 'Shares' to 'Deposit Tokens' (i.e. Stablecoins). For this we use the ratio of 'Deposit Tokens' per 'Share' at the time of snapshot
2. Convert 'Deposit Tokens' to 'Refunds'. For this we use a 1:1 conversion between Stablecoins for simplicity.
All three protocols provided approx. 52% of user deposits in different stablecoins. Yield Yak depositors typically deposit one asset to earn more of that asset. In keeping with that expectation (and because it is feasible with stablecoin), we are refunding the same asset which was deposited. Note: this is different than how the other three protocols have issued refunds. Yield Yak is covering any gas fees and slippage involved in facilitating this for this round of refunds.
