The SushiSwap decentralized exchange has narrowly avoided becoming the latest DeFi hack victim thanks to assistance from a white hat hacker. A security researcher from venture capital firm Paradigm known on Twitter as “samczsun” has managed to save SushiSwap and its MISO platform from a potential loss of as much as 109,000 ETH. In a blog post published on Aug. 17, the programmer described how he began examining the smart contract code for the BitDAO token sale at SushiSwap’s token launchpad platform, MISO.
