The Shanghai upgrade is the Ethereum network update that enabled validators to withdraw staked ETH for the first time, completing the network's multi-year move to proof of stake and turning staked ETH from a locked position into a liquid, redeemable asset.
Completing the proof-of-stake transition
Before Shanghai, anyone who staked ETH to help secure the network had no way to get their 32 ETH principal or accumulated rewards back out. That changed with the Shanghai and Capella hard fork, which activated withdrawal functionality on both the execution and consensus layers. Removing that lockup risk mattered because it let institutional and retail stakers treat staked ETH as a normal, exit-able yield position rather than a one-way commitment, which in turn made staking far more attractive as a baseline digital yield asset.
How liquid staking derivatives work
Not everyone wants to run their own validator or wait in a queue to unstake, so liquid staking protocols such as Lido and Rocket Pool issue receipt tokens, stETH and rETH being the best known examples, that represent a claim on staked ETH. These tokens accrue staking rewards automatically in the background while remaining freely tradable, so a holder can deposit them into lending markets or liquidity pools as collateral without ever unstaking the underlying ETH. That combination of yield plus liquidity is what pushed liquid staking tokens into a central role across decentralized finance.
Weighing the risks before staking
Holding a derivative token instead of raw ETH introduces a layer of smart contract risk, since a bug in the staking pool's code could put deposited funds at risk regardless of how sound the underlying protocol is. Validator downtime or double signing can also trigger slashing penalties that quietly reduce yield over time. And because liquid staking tokens trade on secondary markets rather than redeeming instantly one for one, a spike in withdrawal demand during a volatile period can cause the token to trade at a temporary discount to the spot price of ETH, even though it remains fully backed underneath.
What this means for traders
For active traders, the practical takeaway is that liquid staking tokens are not identical to holding ETH outright. Their price can diverge slightly from spot, their yield varies with network-wide staking participation, and their risk profile depends on which protocol issued them. Comparing the peg tightness and audit history across providers is worth doing before parking capital in any single derivative token for an extended period.
