@DeFiGod1 @iearnfinance Great breakdown. Note that my diagram doesn't show the fee taken on the farmed coins, which is redistributed to YFI stakers, see https://t.co/eAWdGSQnrz

[Olivier @oli_vdb]

$YFI is about to go full industrial farming against $YFII. A new yCRV yVault was deployed to farm YFII, immediately dump it for DAI and compound the harvest by using the DAI to farm more YFII 👀

@tx_origin That’s indeed the line that reverts. But in exit() this line occurs first in withdraw() and then again in getReward(). It’s the one in getReward() that actually fails. You can verify this using @TenderlyApp

1/4 I found a bug in the staking contracts of $YFII (the fork of $YFI with weekly Bitcoin-style halvings). The bug is causing an issue with at least two YFII clones: $ASUKA (exit scammed) and $WIFEY (active).

[Olivier @oli_vdb]

@dryruner @tx_origin Yes, and the ASUKA-DAI, cryCRV and WIFEY-DAI pools have indeed minted 5000 tokens each.

[Olivier @oli_vdb]

4/4 That's most likely only an issue for that farmer who can't exit his "gains" since these exceed what is held by the staking contract. Note that if the distribution was made to last 50.6+ years instead of 7 days, the farmer could have exited his massive gains 😱.

[Olivier @oli_vdb]

3/4 As a result, lastUpdateTime (seconds between 1/1/1970 and the last time the rewards were updated), isn't set to the current timestamp but instead keeps its default value of 0.

The reward calculation then considers that the first staker has been farming hard since 1970 💪👩‍🌾

@natefalconer @iearnfinance YFFI is the clone currently being farmed by YFI https://t.co/W4ctkVSp3H

[Olivier @oli_vdb]

Update: the fee is now 0.5% https://t.co/BEmH5bNlk5

[Olivier @oli_vdb]

Note that my diagram doesn’t show the 50% fee taken on the yCRV rewards, which is presumably redistributed to YFI stakers.

512 years later, a new (less bloody) type of AZTEC ceremony. Hoping to ignite at least 52 years of Ethereum privacy! @aztecprotocol

[Olivier @oli_vdb]

@offchainfr Yes the gas cost would start to be quite high relative to the deposit size for a 0.1 ETH mixer. Deploying multiple mixers would also reduce the anonymity set. Withdrawing custom amounts is being researched though. In the meantime you can try Hopper on the Ropsten testnet.

Excited to release the open-source project I've been working on in the last few months: Hopper, mobile-friendly private transfers for Ethereum https://t.co/hc4mkYImea

[Olivier @oli_vdb]

@offchainfr Yes the funds can be seen as coming from the mixer contract. But if you receive ETH from a mixer, it could have been sent by anyone without your knowledge, giving you plausible deniability. The relayer is used so that you can withdraw to a brand new address with no ETH.
