SafeDollar DeFi protocol on Polygon suffers exploit, loses $250k


The Polygon blockchain is experiencing a series of exploits and rug pulls, with another DeFi project losing some of its funds a few hours ago.

SafeDollar DeFi project suffers exploit

The SafeDollar stablecoin project on the Polygon blockchain has reportedly suffered an exploit. The initial losses were estimated to be around $248 million, which could have caused the project to crash to zero. However, it now appears that the project lost $250k.

The earlier reports from DeFi analytics websites DeFiPrime and RugDoc indicated that the attack wiped out $248 million from the project. This would have caused it to crash to zero. However, the SafeDollar development team didn’t issue an announcement via its official Twitter handle.

Instead, the protocol’s Telegram channel issued a warning of the attack to its users, urging them to suspend the trading of the SDO token. The team didn’t specify how much was lost in the attack. The developers said they would announce a post-mortem once they conclude investigations. They also intend to compensate the liquidity providers.

The losses were later realised to be $250k. Popular cryptocurrency analyst Michaël van de Poppe made this known in his tweet. Mudit Gupta, a core developer at Sushiswap, also confirmed that it was $250k, and not the $248 million initially thought.

SafeDollar was exploited today and dumped on the open market for ~$250k. It was an infinite mint exploit. The market cap of $SDO was ~$248mm but there was just $250k in exit liquidity,. The attack happened because SafeDollar incentivized a token that has a fee on transfer. 🧵👇

This is the second time SafeDollar is experiencing an exploit in less than ten days. The protocol detailed a post mortem on June 22, in an attack where it lost 9,959 SDS tokens, worth around $95,000 at the time.

Polygon DeFi protocols suffer exploits and rug pulls

The Polygon blockchain is in the spotlight following a series of exploits and rug pulls of DeFi protocols on its network. Earlier this month, the Malt Protocol experienced a collapse of its elastic supply algorithmic stablecoin. Although not related, the Polywhale project on Polygon shut down, with the developers dumping $1 million of their tokens and pulling an exit scam.

The Binance Smart Chain suffered similar attacks on a few DeFi protocols. According to a Cryptonary report last month, BurgerSwap and Julswap experienced flash loan attacks, resulting in the loss of approximately $7.2 million in altcoins.

The Polygon blockchain remains home to some leading projects. Recently, popular digital artist Beeple opted to launch his new NFT platform on the Polygon blockchain.
