API Keys

Block #87670
The Syscoin block explorer indicated more than a billion SYS coins under the “Value Out” parameter. Several users and news outlets have speculated over a possible exploitation of the Syscoin protocol to mint new coins, given the maximum supply is currently capped at 800M, and a connection to the subsequent trading activity on binance.
However, on further review, it was clear that it wasn’t an exploit but simply a user moving 45M coins multiple times within the same block. In a tweet, Syscoin made clear that “After investigating the #Syscoin blockchain is safe. We are asking exchanges to reopen.”
In a statement, Keyare, Syscoin team developer, stated “We saw suspicious activity and to mitigate risk, asked exchanges to halt trading while we investigated. Bittrex and Poloniex took immediate action and Binance launched their own investigation. Our tweet was accurate but misinterpreted as a “hack” by media.”
“There was no exploitation of the Syscoin blockchain. There was no minting of coins. The blockchain shows this. It was a series of events that coincided with extremely odd movements in Binance. We will have an official report later today.” he further stated.
SAFU Fund
In an official post-incident , Binance stated:
“To protect the future interests of all users, Binance will create a Secure Asset Fund for Users (SAFU). Starting from 2018/07/14, we will allocate 10% of all trading fees received into SAFU to offer protection to our users and their funds in extreme cases. This fund will be stored in a separate cold wallet.”
Binance also announced that it has rolled back irregular trades. They also stated that they would provide zero fee trading on their platform between 5th and 14th july for all the users who were negatively affected during the unusual SYS trading activity. The company would also compensate all the users with a 70% rebate on trading fees between 5th and 14th july in the form of BNB for the downtime.
