Synthetix, a synthetic asset issuance platform, disclosed a smart contract vulnerability discovered by independent security researcher Sam Sun. Synthetix stated that users’ assets were not lost. The problem comes from the ether mortgage contract that has been deployed to the main network, but because the contract will not be activated until the end of the three-month trial period, there are still two months left. Synthetix said that while the audit of the mortgage contract upgrade was performed by Sigma Prime, there was a misunderstanding of the intent of the liquidation process. Synthetix has launched the bug bounty program since the beginning of 2019. After the incident, it said that it will update the details of the program and will provide four rewards of 100 sUSD, 500 sUSD, 1000 sUSD, and 5000 sUSD.
