Binance had alt trading for 12hr due to irregular syscoin transactions from a number of API users. Syscoin’s blockchain was supposedly hacked yesterday as abnormal activity took place at block 87670.
More than one billion coins were mined at block 87670. This triggered a red flag because the total supply of the coin is set to be only 888 million.
After the vulnerability was announced, a single SYS coin $0.250221 -0.98% was traded for 96 BTC $6579.77 +0.71% on Binance. Binance removed all existing API keys and asked API users to generate new ones, and alt all transactions. As for right now, the exchange reopened all their service.
