Ethereum (ETH) had a huge week with the completion of its Shanghai hard fork upgrade. The upgrade on the blockchain, also known as "Shapella" now allows for withdrawals for some who have had their deposit contract locked up since 2020. Within about 30 minutes of completion, users made withdrawals of over 5,400 ETH around $10 million worth. With the successful upgrade, Ethereum completed its multi-year transition to a proof-of-stake network.
