You stake the token, the app flips to “earning,” and the APY starts ticking up in real time. The screen leaves out the part that actually binds you: your coins just joined an exit line, and the length of that line depends on everyone else trying to leave the same week. At the protocol level, proof of stake is simple: you lock coins to secure the network and get paid for it. The lock part deserves a receipt.
The exit queue is the real lockup
Ethereum stopped being a one-way door in April 2023, when the Shapella upgrade switched on withdrawals. The door is still rate-limited. Validators exit through a churn limit of roughly 8 to 10 per epoch, and an epoch lasts about 6.4 minutes, so a calm week clears your unstake request in under a day.
Calm weeks aren’t the ones that matter. In July 2025 the exit queue went from 1,920 ETH to over 475,000 ETH in about six days, pushing the wait past eight days, according to Galaxy Research. By August 15, 2025, a record 816,000 ETH (around $3.6 billion) sat waiting to leave and queue time crossed 13 days, per validatorqueue.com data CoinDesk reported. Then the protocol adds roughly a 27-hour delay after your validator actually exits before the funds land in your wallet.
“Unstake anytime” really means “join the queue anytime.” In a crash, everyone joins at once.
Cosmos wrote the wait into the code
Cosmos Hub chains are more upfront about it. The staking module’s unbonding_time parameter is 504 hours: 21 days, fixed, and readable on-chain before you delegate a single ATOM. Delegate today, hit unbond, and the coins come back in exactly three weeks. No queue dynamics, no surprise backlog.
Those 21 days are risk days too. Your stake stays slashable the whole unbonding period, and the Cosmos Hub documentation is blunt about the penalties: double signing burns 5% of the validator’s entire stake, yours included, and extended downtime costs 0.01%. If your validator misbehaves in week two of your exit, the cut comes out of your coins.
Exchange staking runs the same clock and adds a toll
Exchange products look friendlier because the button says “unstake” instead of “send exit message.” Underneath, the same network rules apply. Coinbase says it adds no lockup of its own, but each network’s exit time still runs, and converting a pending unstake to an instant one costs a fee. Some exchange products add their own fixed term on top, and redeeming early typically forfeits the rewards you already earned.
Then the commission. Coinbase’s standard cut is 35% of staking rewards across ETH, SOL, ATOM, DOT, and a handful of others (Coinbase One tiers drop it to 31.75%, 28.5%, or 25.25%). A 3% gross network rate lands near 1.95% in your account. The APY on the screen is already net of that cut, which is exactly why the gross number never appears.
Liquid staking trades the lockup for a price gap
Lido hands you stETH the same day: liquid, usable as collateral, sellable whenever you want. The escape hatch is a market, and markets price panic. In June 2022, with Celsius and Three Arrows unwinding, stETH traded at 0.94 ETH on Curve and the 1:1 ratio took months to recover. Nansen’s post-mortem traced the break to the Terra collapse flooding the pool with sellers. Anyone who needed out that week took roughly 6% less than the ETH sitting behind their token.
Lido also skims 10% of staking rewards, split between node operators and the DAO treasury. And redeeming stETH for real ETH routes through the same validator exit queue we started with. The token is liquid. The asset underneath is not.
The short version
Staking commits three things: an exit wait you don’t control, a validator’s behavior you don’t control, and a fee off the top. Ethereum’s queue ran past 13 days at its August 2025 record. Cosmos prints 21 days in the protocol parameters. Exchange commissions reach 35% of your rewards, and liquid staking adds a market price that can drift below the asset inside. Before you stake, check the unstaking window in days, the commission percentage, and the slashing record of whoever holds the keys. The APY is the last number that matters, and the first one everyone reads.
