Known as Shapella, the latest upgrade to the Ethereum blockchain since its Merge upgrade will enable investors to redeem an offshoot of ether tokens that they have deposited in return for interest on the blockchain network over the past three years.
Such so-called "staked ether" tokens currently account for about 15% of all ether tokens, according to data firm Dune Analytics, and are worth some $31 billion.
Deposits & withdrawals for ETH, OP, ARB and ERC-20 tokens via the Ethereum, Optimism, and Arbitrum networks are now back online," Binance said in a tweet.
The changes will likely lead to heightened volatility for ether, investors have predicted.
In its last significant upgrade, Ethereum in September drastically reduced its energy usage - a move proponents said would give Ethereum an advantage as it seeks to surpass bitcoin.
