Ronin, an Ethereum-linked sidechain made by Sky Mavis specifically for Axie Infinity suffered a major security breach.
The breach led to the theft of about $620 million in cryptocurrency compromising 173,600 Ethereum ETH/USD and 25.5 million USD Coin USDC/USD that were drained from the Ronin bridge in two transaction.
The Ronin bridge and Katana Dex have been halted and the crypto exchange platform Binance also disabled its bridge to/from Ronin as a precautionary measure.
