Here’s what happened at Quantstamp in April:
DeFi Attacks

Attacks rocked multiple prominent DeFi projects this month, from Uniswap to dForce to recently launched Hegic Options.
Both Uniswap and dForce suffered from re-entrancy attacks. Uniswap, a decentralized token exchange, experienced an attack on imBTC, an ERC277 token which it is not designed to support. By exploiting re-entrancy, the attacker was able to make off with roughly 300K in crypto assets.
That same weekend, Lendf.Me, a collateralized lending platform, suffered a similar re-entrancy attack on its imBTC token. This time the damage was more severe, with $25 million stolen. Thankfully, the story ends happily, as the hacker ended up returning the money.

Crypto against COVID

As COVID-19 spreads, the blockchain industry is standing together to help support frontline workers fighting the disease. CryptoAgainstCOVID is a movement, spearheaded by Binance, to raise funds to support equipment for frontline workers, with donations transparently published on the blockchain.
We were happy to contribute to this. Read more or make a donation. here.
Maker Backstop Auction

On March 12th, the price of ETH crashed over 50%. The resulting drop, along with extremely high network traffic, resulted in the MakerDAO system becoming undercollateralized by falling below its 150% collateral requirement.
To fix the collateral shortfall, MakerDAO arranged an MKR auction, where MKR would be minted and sold. Quantstamp, along with other ecosystem players, formed a backstop syndicate, designed to backstop this auction and make sure it succeeded.
