Newsletter #2: Yield Farming is HOT – but Farmers Beware of scams

I’ll keep this week’s newsletter short and sweet. Primary markets (BTC, ETC) have been relatively stable, which an overall trend of recovery after last week’s flash crash on the 2nd of Aug. The crash was primarily targeted at leveraged traders, with over $1 Billion USD worth of contracts being liquidated across multiple exchanges. After this crash, prices quickly recovered nearing previous highs. This goes to show one of the dangers of over-leveraged positions, as there can be sudden volatility in either direction causing positions to be liquidated.

Yield farming is HOT, but farmers Beware!

Personally, I’ve been yield farming quite a lot this week with generally favorable results. Please note that Yield Farming is EXTREMELY dangerous as it involves the use of potentially unverified audited code on smart contracts. Do Your Own Research (honestly this is what’s taking up most of my time)

Starting off, Yearn’s developer Andre Cronje (check this interview summary) launched Yvaults 2. Simply funds saved there will automatically be invested into the best strategy possible to generate more profit. The new system allows for the addition of new strategies too – basically what the founder Andre sees fit. Annual returns can vary – we’ve seen numbers between 50% and 200% APY. However, there isn’t a good way to calculate for the time being.

One of the biggest trends this week is the emergence of $YFI clones. $YFI farming was extremely popular 2 weeks ago as it has extremely high yields. However – this has since paused as there is no new distribution of $YFI. Many opportunistic developers sought to create forks for $YFI that would distribute new coins such as $YFII, $YFFI, $YFT, and $WIFEY (just to name a few) in a similar fashion. One of the biggest risks with these $YFI clones is that the use un-audited code  – so they are extremely vulnerable to smart contract bugs (such as this one ).

BEWARE: $ASUKA & YYFI exit scams

Two infamous projects pulled of exit scams in the past month, with developers minting a huge number of tokens and trading it into DAI. Both $ASUKA and $YYFI preyed on farmers who added liquidity to balancer pools that are required to farm the tokens. These pools are dangerous because the funds are directly used as a counter-party to trades, meaning that the pool’s DAI will directly be used to buy up the corresponding token. The $YFFI developer minted 1,000,000 $YFFI and sold it immediately, making off with $70,000 in the process (could have been more if he understood how balancer works).

For the time being, I’m staying away from any yield farming involves liquidity pools.


This week I’m testing out CREAM mining. CREAM is a project inspired by Compound and they are offering airdrops of CREAM token to those supply / borrowing from the protocol. Currently, the project’s code is up on GitHub but is pending formal audits. This means there will be potential smart contract risks with farming here.
