If you've been following DeFi or Ethereum over the past few months, you've likely heard the term "flash loan" mentioned again and again.
This new DeFi primitive has been at the core of a number of economic exploits and arbitrages.
A thread on the basics of flash loans - 👇
You can deposit Ethereum into Aave, then withdraw stablecoins for yield farming in Yearn, for instance.
On-chain loans have garnered much traction, with total debt outstanding moving toward $2.5 billion.
If your collateral slips below the threshold, you're liquidated, resulting in a fee anywhere from 5-13%.
Flash loans are non-custodial, take place over the course of one block, and require no collateralization.
That's to say, the coins you borrow never appear in your wallet.
So what the hell? What are flash loans used for?
More often than not, arbitrage.
Here's a simple example I spotted in the mempool a few months back:
https://t.co/hiBHuTerQH
More on what's happening in the next tweet.
- Traded that USDC for 2,028,367 DAI in Curve's Y pool
- Traded that DAI for 2,064,182 USDC in Curve's sUSD pool
- Paid dYdX back + 2 wei
All in one block...
Profit: 16,182 USDC
Cost: $60 in gas
Crazy, right?
There are also advanced arb strategies that enabled the "attacks" on Eminence, Harvest, etc.
Let's take a look.

Bitcoin is resilient around $13k, Ethereum hit $420, and DeFi TVL is at an ATH at $12 billion.

As DeFi continues to grow, decentralized exchanges will remain pivotal.
Here\u2019s a thread on the outlook of the AMM market (Uniswap, Balancer, Sushiswap, LinkSwap, DODO). pic.twitter.com/LPWVkCaKbM
- Borrow 15 million DAI from Uniswap
- Mint EMN
- Burn some EMN for eToken, driving up EMN up the curve
- Sell remaining EMN for DAI
- Make millions
The bug was the bonding curve was steep and could be manipulated.

The bug was that Harvest didn't use the get_virtual_price() function from Curve, allowing for manipulation.
Governance attacks are a good example. They're scary but still kind of sick, to be honest.
On October 26th, a user used flash loans to influence a MakerDAO proposal.
https://t.co/naqLqOi1bS
They
- borrowed $20m worth of WETH from dYdX
- deposited it on Aave to borrow $7m worth of MKR
- Locked MKR in governance
- Voted on a proposal
- Unlocked MKR
- Sent MKR, then ETH back
Flash loans will be similar in concept to flash mints but will involve the minting, then burning of tokens rapidly to accomplish some feat.

So the cryptocurrency industry has basically two products, one which is relatively benign and doesn't have product market fit, and one which is malignant and does. The industry has a weird superposition of understanding this fact and (strategically?) not understanding it.
The benign product is sovereign programmable money, which is historically a niche interest of folks with a relatively clustered set of beliefs about the state, the literary merit of Snow Crash, and the utility of gold to the modern economy.
This product has narrow appeal and, accordingly, is worth about as much as everything else on a 486 sitting in someone's basement is worth.
The other product is investment scams, which have approximately the best product market fit of anything produced by humans. In no age, in no country, in no city, at no level of sophistication do people consistently say "Actually I would prefer not to get money for nothing."
This product needs the exchanges like they need oxygen, because the value of it is directly tied to having payment rails to move real currency into the ecosystem and some jurisdictional and regulatory legerdemain to stay one step ahead of the banhammer.
If everyone was holding bitcoin on the old x86 in their parents basement, we would be finding a price bottom. The problem is the risk is all pooled at a few brokerages and a network of rotten exchanges with counter party risk that makes AIG circa 2008 look like a good credit.

Once upon a time there was a Raja named Uttānapāda born of Svayambhuva Manu,1st man on earth.He had 2 beautiful wives - Suniti & Suruchi & two sons were born of them Dhruva & Uttama respectively.
#talesofkrishna https://t.co/E85MTPkF9W
Now Suniti was the daughter of a tribal chief while Suruchi was the daughter of a rich king. Hence Suruchi was always favored the most by Raja while Suniti was ignored. But while Suniti was gentle & kind hearted by nature Suruchi was venomous inside.
#KrishnaLeela
The story is of a time when ideally the eldest son of the king becomes the heir to the throne. Hence the sinhasan of the Raja belonged to Dhruva.This is why Suruchi who was the 2nd wife nourished poison in her heart for Dhruva as she knew her son will never get the throne.
One day when Dhruva was just 5 years old he went on to sit on his father's lap. Suruchi, the jealous queen, got enraged and shoved him away from Raja as she never wanted Raja to shower Dhruva with his fatherly affection.
Dhruva protested questioning his step mother "why can't i sit on my own father's lap?" A furious Suruchi berated him saying "only God can allow him that privilege. Go ask him"

THREAD: 12 Things Everyone Should Know About IQ
1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE
2. The heritability of IQ *increases* from childhood to adulthood. Meanwhile, the effect of the shared environment largely fades away. In other words, when it comes to IQ, nature becomes more important as we get older, nurture less. https://t.co/UqtS1lpw3n
3. IQ scores have been increasing for the last century or so, a phenomenon known as the Flynn effect. https://t.co/sCZvCst3hw (N ≈ 4 million)
(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)
4. IQ predicts many important real world outcomes.
For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3
5. Higher IQ is associated with a lower risk of death from most causes, including cardiovascular disease, respiratory disease, most forms of cancer, homicide, suicide, and accident. https://t.co/PJjGNyeQRA (N = 728,160)
