Optimism attacker rejects 18 million stolen OP tokens

 


A bad transfer with serious consequences cost the developers of the Ethereum Layer-2 solution 20 million Optimism tokens (OP) on June 9, with a value of around 35 million US dollars at the time.

As reported, the attacker took advantage of an error made by the liquidity provider Wintermute in synchronizing its Optimism L2 receiving address with the corresponding Ethereum L1 address.

Within 24 hours of Wintermute sharing his research results with the Optimism team, an anonymous hacker stole all 20 million OP tokens from said Ethereum L1 address.

The hacker initially sold 1 million OP tokens for Ether (ETH) and kept the other 19 million.

On Friday, June 10, the Optimism team then announced via Twitter that the attacker sent 17 million OP tokens back to an Optimism Foundation Ethereum address in a total of 17 transfers .

Before returning the 17 million OP tokens, the attacker sent an on-chain message and one million OP tokens to Ethereum co-founder Vitalik Buterin. In the message, the stranger asked Buterin to verify the Optimism receiving address and send the 1 million Optimism tokens to that address. As assured in the message to Buterin, the attacker then sent 17 million Optimism tokens to the previously verified OP receiving address, returning 18 of the 20 million OP tokens.

As a bonus, the attacker keeps a further 1 million OP tokens in addition to the OP tokens already exchanged in Ethereum.

The Optimism team announced that Wintermute will make up for the missing 2 million OP tokens.

After the announcement of the news, the OP price was able to recover by almost 20 percent to USD 0.98 in the meantime, but is now trading 20 percent lower again in the region of USD 0.80 in the course of the current overall market weakness.

From offchain to offchain: Statechains meets Lightning

  Without a doubt, the most significant off-chain Bitcoin solution is the Lightning network. But in its wake, the statechain has emerged as an intriguing replacement. There is currently a proposal to link the two offchain networks. From an ocean, for example, you can see sunbeams glistening in the water, waves rippling, and possibly a jellyfish drifting toward the light. But you only see a small portion of it. The distance from the sea's surface to its bottom is hundreds of meters. It has dozens of different fish species swimming in it, crabs and starfish crawling on the bottom, shells clinging to rocks, and sea plants climbing up. A completely new world starts where your gaze diverges. You can picture a blockchain like Bitcoin, just like the sea. What you see on the outside is only a small portion of what is actually there; the set of UTXOs (coins) and transaction history that full nodes store are just the beginning of a much larger world. It's the plan, at least. With Bitcoin

MSP Recovery and Tokenology aim to optimize healthcare with the help of Polygon

  MSP Recovery LLC, a Miami, US-based healthcare provider with an estimated enterprise value of $32.6 billion, is partnering with Web3 company Tokenology to jointly launch a new blockchain platform called Lifechain.

British financial regulator criticizes cooperation between Binance and Paysafe

  The British financial regulator FCA has expressed concerns about the partnership between market-leading crypto exchange Binance and payment service provider Paysafe. As the British regulator complains, the partnership gives Binance access to the influential British payment network Faster Payments Service (FPS), from which the crypto exchange was previously cut off. Last June, the FCA ordered Binance to stop all business activities in Great Britain. As a result, prominent banks such as Barclays have terminated their cooperation with the leading crypto trading platform . Through the cooperation with Paysafe, Binance can now again offer deposits in British pounds sterling and transactions within the European Payments Area (SEPA). However, this fact is a thorn in the side of the FCA, as it classifies the crypto exchange as a “considerable risk factor”. However, the financial regulator sees little room for maneuver to counteract this, as the Financial Times reports . “ Paysafe understands
