The highly anticipated Ethereum Shanghai upgrade, also known as Shapella, is set to go live on April 12, 2025, at 22:27:35 UTC. This landmark event marks the first time validators will be able to withdraw their staked ETH and accumulated rewards from the Beacon Chain—ushering in a new era of flexibility and liquidity for the Ethereum ecosystem.
Backed by the Ethereum Foundation’s protocol support team, the upgrade follows a successful transition on the Goerli testnet. With both execution and consensus layer clients aligned, the mainnet activation is now imminent. The upgrade combines “Shanghai” (execution layer) and “Capella” (consensus layer), representing a critical milestone in Ethereum’s post-merge evolution.
Unlocking Staked ETH: How Withdrawals Work
Post-upgrade, validators gain two withdrawal options:
- Partial Withdrawals: Validators can withdraw excess rewards above 32 ETH while continuing to validate blocks. These earnings—accumulated over time—are immediately eligible for withdrawal.
- Full Withdrawals: Validators may exit the network entirely, withdrawing their full balance (including the initial 32 ETH stake). This requires sending an exit message and joining a processing queue.
Each slot (occurring every 12 seconds) allows up to 16 withdrawal requests. While partial withdrawals are processed more swiftly, full exits face delays due to queue dynamics. At current network capacity, Ethereum can handle approximately 57,000 validator exits per day, matching its daily validator entry limit.
For users relying on liquid staking derivatives (LSDs) or centralized platforms like Coinbase or Binance, withdrawal timelines depend on individual service policies:
- Coinbase committed to processing withdrawals within 24 hours post-upgrade.
- Lido requires a follow-up protocol upgrade around mid-May before enabling ETH withdrawals for stETH holders.
- Rocket Pool users must wait for the "Atlas" upgrade scheduled for April 18, 2025.
This staggered rollout helps mitigate sudden network congestion and potential market shocks.
Assessing the Potential ETH Sell-Off
A key concern among investors is whether the unlock will trigger significant sell pressure. To assess this, we must examine who holds staked ETH and their likely behavior post-unlock.
Approximately 60.3% of staked ETH flows through LSD platforms like Lido (33.2%) or centralized exchanges (27.1%). These users already enjoy liquidity via tokens like stETH or cbETH—meaning they’ve had opportunities to trade or leverage their positions long before the upgrade. As such, their incentive to sell upon withdrawal is relatively low.
The real uncertainty lies with the remaining ~40% of stakers who directly deposited into the deposit contract—mostly solo stakers or those using non-custodial services. Their ETH has been locked since inception, creating pent-up supply that could enter markets once accessible.
According to Nansen, about 59% of these non-LSD stakers (roughly 3.6–4 million ETH) are in profit and may consider partial or full withdrawals. However, actual sell pressure is expected to range between 1.2 million and 3 million ETH, spread out over weeks due to daily withdrawal caps.
Three Phases of Post-Upgrade Sell Pressure
Nansen outlines a phased sell-off pattern:
- Phase One (First 27 Hours): Driven by partial withdrawals of accumulated rewards—estimated at 84,000–125,000 ETH per day.
- Phase Two (Days 3–4): Peak pressure emerges as both partial and full withdrawals surge—projecting 136,000 ETH/day in reward withdrawals and 173,000 ETH/day from full exits.
- Phase Three (Days 19–52): Sustained but reduced outflows from full exits—averaging 48,000–53,000 ETH/day.
Compared to the 30-day average exchange inflow of 313,533 ETH, these figures represent 15%–55% increases, potentially dampening price momentum temporarily. Arcana Research estimates 1.3 million ETH could hit markets within 10 days, with peak daily sell pressure reaching $527 million** (assuming $1,800/ETH)—equivalent to 6.4% of daily trading volume**.
However, this impact may be cushioned by structural shifts favoring long-term holding.
Rising Staking Adoption Could Offset Sell Pressure
One often-overlooked counterbalance is the upgrade’s potential to boost staking participation. Currently, only about 15% of circulating ETH is staked—far below other proof-of-stake chains where rates reach 50–70%. The primary deterrent? Uncertain lock-up periods.
With flexible withdrawals now possible, Ethereum becomes significantly more attractive for institutional and retail investors alike. Experts project staking rates could rise 2x to 4x over time.
This transformation turns ETH into a yield-generating asset with predictable exit options—aligning it more closely with traditional financial instruments while preserving decentralization.

Strong On-Chain Demand Signals
Despite fears of a sell-off, broader on-chain metrics suggest strong underlying demand:
- Exchange reserves of ETH have dropped to 10.31% of circulating supply—the lowest since 2015—indicating holders are moving assets off exchanges and into self-custody.
- Over 23.3 million addresses now hold at least 0.01 ETH, an eight-month high.
- Whale activity is rising: addresses holding more than 1,000 or 10,000 ETH have increased recently.
These trends reflect growing confidence in Ethereum’s long-term value proposition—particularly among retail and institutional investors.
Muye Sheng, co-founder of non-custodial staking pool Ebunker, notes that while most staking currently occurs via LSDs or centralized providers, solo and non-custodial staking will gain traction post-upgrade—especially once early withdrawal queues clear.
“True ownership means controlling your keys. As users realize the benefits of self-managed staking, we’ll see a shift toward decentralized participation—the endgame of Ethereum staking.”
Derivatives Market Shows Cautious Optimism
As the upgrade nears, derivatives markets offer insight into trader sentiment.
- Futures Premium: The annualized premium for ETH futures briefly rose to 4% on March 29, nearing the healthy range of 5–10%. Though still neutral, this marks a four-week high—suggesting mild bullish positioning.
- 25% Delta Skew: Since March 22, skew has remained flat around zero, indicating balanced expectations for upside and downside moves.
Notably, despite increased regulatory scrutiny on exchanges, derivatives markets haven’t shown panic or aggressive shorting—a sign of underlying market resilience.
Frequently Asked Questions (FAQ)
Q: What is the Shanghai upgrade?
A: It’s a major Ethereum network upgrade (Shapella) enabling validators to withdraw staked ETH and rewards for the first time since the Merge.
Q: When does the Shanghai upgrade happen?
A: April 12, 2025, at 22:27:35 UTC.
Q: Will all staked ETH be unlocked immediately?
A: No—withdrawals are processed in batches due to per-slot limits. Full exits may take days or weeks depending on queue length.
Q: How could the upgrade affect ETH price?
A: Short-term selling pressure is possible, especially in days 3–4 post-upgrade. However, increased staking adoption and strong holder demand may offset downward momentum over time.
Q: Can I withdraw my stETH after the upgrade?
A: Not immediately—Lido plans to enable withdrawals only after its own protocol upgrade in mid-May 2025.
Q: Is now a good time to start staking ETH?
A: Yes—the ability to withdraw anytime reduces risk. With potential staking yields and rising participation, long-term incentives are stronger than ever.
