1) Would you take a loan with negative interest rate (you are paid for borrowing) with zero risk of liquidation? I would and I did. It's (temporarily) possible on @RulerProtocol on a few collateral types: $BDI, $ibBTC and $NEAR. How does it work? 👇 Image
2) Let's say you have $BDI and want to borrow DAI (you can also choose USDC and USDT). For each BDI deposited as collateral, you are currently able to borrow 150.39 DAI. At the same time, you will only have to repay 150 DAI. You are paid 0.39 DAI which corresponds to -3.34% APR. Image
3) The more you borrow, the higher your borrowing APR becomes. For 100 BDI of collateral, you can borrow 15024 DAI and you will need to repay 15000 only. It's still negative borrowing APR of -2.06%. It becomes positive when you borrow more than 40.5k DAI. ImageImage
4) The best part about loans on @RulerProtocol is that they are never liquidated before expiry date. Sudden market crash can't harm you at all. Temporary price movements of collateral are irrelevant. You only need to repay the loan before expiry. However, not necessarily...
5) Sometimes it makes sense not to repay the loan at all. Look: for 1 $BDI of deposited collateral, you need to repay 150$ (Mint Ratio for BDI = 150). So if at expiry BDI is worth less than 150$, it makes sense to leave it there and keep your borrowed stablecoins.
6) To sum up, you are paid to take a loan which can't be liquidated if you repay before expiry and in case of market crash it may be more profitable for you to not repay it at all. Sounds like magic? Yes, magic Internet money lego called DeFi. Enjoy!

1) I've noticed many people think that Uniswap v3 $UNI solves the problem of impermanent loss (IL). It doesn't. Actually, it's just the opposite. Concentrated liquidity substantially increases the risk of IL. Let's quickly break down why it happens.
2) I think this common misconception may have been unwillingly originated by @haydenzadams. He wrote:

Uniswap v3 provides the only possible "solution" to impermanent loss and price impact

But he didn't use quotation mark ("solution") without a reason.
3) In fact Hayden's long thread (worth reading!) explains exactly the trade-off between IL and price impact. The "solution" he meant is that v3 offers liquidity providers (LPs) a possibility to choose their preferred level of exposure to IL.

1) Almost 90% APR on $BTC with hardly any risk of impermanent loss... This is fully boosted return on mBTC/HBTC pool on @mStable_. Boost requires to lock some $MTA but lock terms are more favorable than trying to get max boost on Curve by locking $CRV. See 🧵 for more details.
2) Let's first explain what mAssets are. They are meta-stablecoins based on baskets of pegged tokens. mUSD is USD stablecoin which can be minted by depositing sUSD, DAI, USDC or USDT into the basket. mBTC is pegged to BTC and is backed by a pool of renBTC, WBTC and sBTC.
3) Feeder Pools are liquidity pools that contain two assets: 50% of mAsset (mUSD or mBTC) and 50% of any other pegged asset (BUSD/GUSD for mUSD, HBTC/TBTC for mBTC). They are similar to pools on Curve which pair "exotic" stables (e.g. $lUSD, $alUSD) with 3pool (USDT+USDC+DAI).

This is a great thread which uses the on-chain data from last weeks to prove that passive LP strategies on $UNI v3 will be substantially outperformed by active LP strategies (e.g. developed by @VisorFinance). Let me add a few comments to emphasize how big this difference can be.
TL;DR:
- Current comparisons of LP strategies in $UNI v3 overoptimistically present performance of passive ones.
- Passive LPing doesn't stand a chance vs active.
- Bullish on active LP strategy providers, i.e. $VISR
1) @fusion_hodl made a great comparison of passive vs active LP strategy for ETH-USDT since v3 launch. These 3 weeks have been very generous for LPs in this pool. Huge market volatility resulted in a lot of fees and relatively low impermanent loss (IL).

1) During this market crash, all the prices dumped heavily. It didn't matter if it was a meme coin like $DOGE or $SHIB or capital asset like $SUSHI or $BNT. I hoped fundamentally strong projects would be more resilient to such violent movements. But maybe they still will be? Image
2) I've been very conservative during this bull market. I didn't buy any meme token and decided to stick to DeFi projects which generated revenues. I was ok with $DOGE, $SHIB and $SAFEMOON substantially outperforming my portfolio. I just wanted to play a safe long term game.
3) I focused on DeFi tokens because they are not "coins" like the majority of vapor projects from the previous cycle. They are more like capital assets - projects generate revenues and, therefore, tokens can be subject to traditional valuation metrics.

Today was a good opportunity to see if high volatility on the market, with stable coins losing their pegs, can impact leveraged farming of $MATIC rewards on $AAVE. Let's see what happened with my position. 🧵👇
The idea of leveraged farming consists in iterative lending and borrowing of the same asset. Using the same asset is supposed to protect the position from liquidation even if debt to collateral ratio (D/C) is very high and close to liquidation ratio.
I assumed earlier that liquidation of such position would not be possible even in case of oracle failure. Today stable coins substantially deviated from their 1$ peg. How did it impact my risky leveraged $USDC farm at 80% D/C (liquidation ratio at 85%)?

1) I've been liquidity provider (LP) on Uniswap v2 long enough to understand that it was never an easy passive yield. If you didn't actively counteract impermanent loss (IL), it would most likely eat all your profits from fees. How does v3 impact life of LPs? Let's explore.
2) V2 didn't offer LPs any options to manage their liquidity pools. Each LP participated in the same market making strategy (x*y=k). To counteract impact of IL, LPs could merely average their entry prices to the pool and try to time their exit correctly.
3) V3 changes this dramatically. Each LP owns a unique market making (MM) strategy by defining a price range on which they wish to provide liquidity to. This way LPs can easily express their opinions on market movements and compete with other LPs.
