🦹🏻‍♂️ Poly Network Hacked For Over $600M In Biggest DeFi Exploit Ever

TLDR At 6am ET on August 10, over half a billion dollars worth of crypto assets were stolen from Poly Network, a cross-chain protocol that facilitates token swaps across multiple blockchains including Ethereum, Binance Smart Chain and Polygon.

RECORD With the total drained at $600M, this is the biggest DeFi hack in history, dwarfing the $59M EasyFi exploit that held the unenviable record until now.

STEAL According to the project, the attacker was able to “exploit a vulnerability between contract calls” and steal $270M worth of Ethereum-based assets, $250M of assets on Binance Smart Chain, and nearly $85M USDC on Polygon

🎨 Auction of Monet NFT Spurs Questions About Authenticity and the Future of Art

TLDR Michelangelo drew inspiration from the Greco-Roman statues of Classical antiquity to sculpt his masterpiece David. Van Gogh paid homage to the vibrant colors in the woodblock prints of Hokusai and Hiroshige. Great artworks of the past live beyond their creators to inspire great artworks of the future. Digital art and NFTs are no exception. 

BUNDLED But there’s a difference between drawing inspiration from art history and drawing over historical art. Now, as the NFT market continues to gain traction in the mainstream art world, some people are using the opportunity to create NFTs based on famous works from the past. In some cases, these NFTs are even being bundled with the originals. 

ORIGINAL This brings up a few important questions: Would attaching an NFT to a physical artwork alter the value of the original? Is there any real utility for an NFT linked to a historic artwork? And who has the right to mint an NFT of an artist’s work when the original artist is long-deceased?

👨🏻‍🏫 Defiant Degens: How to Farm Up to 755% APR with Tokemak TOKE Rewards

In this week’s installment, the indomitable DeFi Dad shows us how to use a new protocol called Tokemak.

Background on Protocol: A new DeFi protocol called Tokemak recently launched its “DeGenesis” event to distribute the native token TOKE. This token will govern its protocol devoted to single-sided liquidity provisioning. 

To understand Tokemak, it helps to familiarize yourself with Bancor’s pioneering single-sided LPs, which launched almost a year ago. Single-sided LPs allow liquidity providers to lend a single asset to be paired with other assets in AMM (automated market-maker) liquidity pools, and hence avoid the dilemma of impermanent loss.

📈 Market Maker Flaws Open Door to Middleware Providers in Race for Liquidity

In this week’s Research piece, Kieran Smith examines how automated market makers are turning into “financial zombies” chomping on liquidity to stay active, and how that’s paving the way for a new powerful entrant in DeFi — Middleware providers. Often overlooked as basic infrastructure plays, middleware software makers play a vital role in tech ecosystems.

The yield farming revolution has been one of the biggest  stories in DeFi over the last year, thanks largely to automated market makers (AMM). Operating behind the scenes,  these protocols attracted billions of dollars into smart contracts. Spurred by incentives in the form of newly minted tokens, investors dove into AMM’s liquidity pools and changed the DeFi landscape.

Yet while the trading volume of AMMs almost put them on par with centralized crypto exchanges, they have an inherent flaw: They have to be kept alive artificially like the walking dead.

To navigate fit the bottleneck of blockchain throughput, AMMs reduce the market making mechanism for crypto assets to two liquidity pools and an exchange rate that naturally adjusts based on relative demand. This primitive model is similar to a merchant in an ancient marketplace, swapping grain and beans between two piles on request.
