Shapella — staked ETH can finally be withdrawn
The last missing piece of the Merge. Staking became a round-trip, and liquid-staking tokens exploded.
When the Beacon Chain launched (2020) and even after the Merge (2022), staked ETH was a one-way door — you could deposit and validate, but not withdraw. Shapella (Shanghai + Capella) opened the exit.
How exits actually work
Shapella enabled two things: partial withdrawals (rewards accrued above the 32 ETH stake get swept automatically) and full exits (a validator leaves and reclaims its principal). To keep the chain stable, exits flow through a rate-limited queue — only so many validators can leave per epoch — so a stampede can't drain Ethereum's security overnight.

(prevents a same-day mass un-stake)Why it de-risked staking
Once withdrawals worked, staking became a normal round-trip instead of a leap of faith. Counter-intuitively, *enabling* exits made more people comfortable staking — and supercharged liquid staking (stETH and friends), where you stake but hold a liquid, composable receipt token you can use across DeFi.
