Grayscale staked 102,400 ETH, valued at about $237 million, through its Grayscale Ethereum Mini Trust over the past 10 hours, according to blockchain tracker Lookonchain. The move involves staking (locking crypto to help secure a blockchain and earn rewards), a mechanism used on Ethereum’s proof-of-stake network to support validation and generate yield. The transaction highlights how regulated crypto investment vehicles can use on-chain strategies to manage Ether holdings while remaining tied to Ethereum’s network economics.
