The Shanghai Upgrade Explained
The Ethereum Foundation's protocol support team recently announced the Shapella upgrade (commonly called the "Shanghai Upgrade") will activate on the mainnet following successful testing on the Goerli testnet. Scheduled for April 13 at approximately 6:27 AM UTC, this upgrade enables validators to withdraw ETH from the Beacon Chain while introducing new execution and consensus layer functionalities.
Post-upgrade, validators running independent nodes can choose between:
- Partial withdrawals: Extracting staking rewards while keeping the 32 ETH validator active (processed automatically via network scanning)
- Full withdrawals: Removing the entire 32 ETH balance to exit validation (requires manual queueing)
Withdrawal processing speeds depend on network demand:
- Partial withdrawals: ~16 requests per slot (12-second intervals)
- Full withdrawals: ~57,000 nodes processed daily (maximum capacity)
Stakeholder Withdrawal Timelines
Major staking providers have established different withdrawal schedules:

ETH Sell Pressure Analysis
Current Staking Distribution
- Liquid Staking Derivatives (LSDs): 60.3% (Lido 33.2%, CEXs 27.1%)
- Direct Stakers: 40% (previously illiquid)
Nansen research indicates:
- 59% of illiquid ETH (3.62-4M ETH) is profitable
- Estimated sell pressure: 1.2-3M ETH (released gradually)
- Three-phase selling timeline:
| Phase | Duration | Daily ETH Unlock | Source |
|---|---|---|---|
| 1 | 27 hours | 84K-125K | Partial withdrawals |
| 2 | Days 3-4 | 309K | Partial + full |
| 3 | 19-52 days | 48K-53K | Full withdrawals |
Arcana Research projects:
- 1.3M ETH potentially sold within 10 days
- Peak daily selling: $527M (at $1800/ETH)
Counterbalancing Factors
- Increased staking participation (current rate: ~15% vs. typical PoS 50-70%)
- Reduced uncertainty for institutional stakers
- Strong holder confidence (exchange supply at 2015 lows)
Market Indicators
Spot Demand
- 23.3M addresses hold ≥0.01 ETH (8-month high)
- Whale wallets (>1K ETH) growing
Derivatives Signals
- Futures premium: 4% (neutral/bullish)
- Options skew: Neutral since March 22
- No significant short buildup pre-upgrade
FAQ: Shanghai Upgrade Concerns
Q: Will unstaked ETH flood the market?
A: Gradual daily limits (57K nodes/day) prevent sudden dumping. Most LSD-held ETH already trades freely.
Q: Should I unstake immediately?
A: Consider gas fees and queues. Solo stakers may wait 1-2 months for smoother withdrawals.
Q: How does this affect ETH's price?
A: Short-term pressure possible, but higher staking participation may provide long-term support.
Q: Are exchanges ready for withdrawals?
A: Major platforms like Coinbase have systems in place, but expect initial congestion.

Conclusion
While the Shanghai Upgrade introduces measurable sell pressure, Ethereum's built-in withdrawal throttling and growing staking demand create natural market balancing mechanisms. The true test lies in ETH's ability to absorb unlocked supply while maintaining its position as the leading smart contract platform.
