The Digital Chamber filed an amicus brief urging the dismissal of the New York lawsuit seeking ownership of 39,069 dormant Bitcoin wallets, arguing it would set a dangerous precedent for self-custodial wallets. Blockchain trade association the Digital Chamber filed an amicus brief in the New York lost property case seeking ownership of thousands of dormant Bitcoin addresses.

One crypto trader noted the $2 million loss could have been prevented had the victim read the transaction route before signing the transaction. A trader who swapped $2.01 million worth of Ether on a decentralized exchange has been left with just $14,500 worth of tokens after a router directed the order through a low-liquidity pool, allowing an Ethereum block builder to profit massively from a same-block arbitrage trade. The trader swapped 1,126.44 of Ether (ETH) but only received 5,776 Lighter (LIT) tokens, in a “textbook case of same-block backrun extraction,” according to GoPlus Security. “This was a real, highly imbalanced backrunner arbitrage, not a classic sandwich attack,” GoPlus Security said. Titan Builder was the biggest beneficiary, walking away with $1.8 million from the transaction, which took place on Monday at 1:59 am UTC. Read more
