The results propose that there are 1000’s of supplemental wallets that have cryptocurrency tokens and could at present be susceptible to added attacks from the however-unknown hacker.
Homeowners of a Slope wallet are strongly recommended to transfer all tokens into a different system of storage as before long as achievable, this kind of as a hardware ledger or centralised exchange.

“We are operating with developers, security gurus, and protocols from all through the ecosystem to work to discover and rectify [the situation].
“We are however actively diagnosing, and are committed to publishing a whole write-up-mortem, earning again your believe in, and generating this as suitable as we can.”
As of Wednesday, extra than 9,000 wallets experienced been drained, with the selection expanding.
