Understanding the Shanghai Upgrade
The Ethereum Foundation's protocol support team announced that following a smooth transition on the Goerli testnet, the Shapella upgrade (colloquially known as the "Shanghai Upgrade") will activate on the mainnet. This upgrade combines execution-layer ("Shanghai") and consensus-layer ("Capella") client hard forks.
Key Dates and Functions:
- Activation Time: April 12, 2023, at 22:27:35 UTC.
- Primary Feature: Enables validators to withdraw ETH from the Beacon Chain after over two years of locked staking.
Withdrawal Mechanics
Partial Withdrawals: Validators can claim rewards exceeding 32 ETH while continuing to validate blocks.
- Processing Speed: 16 partial withdrawals per slot (every 12 seconds), with queues potentially taking hours.
- Auto-Scan Feature: Periodically redistributes excess balances (>32 ETH) to designated addresses.
Full Withdrawals: Validators exit the network by withdrawing their entire 32 ETH stake.
- Queue Times: Longer delays expected due to high initial demand. The network processes ~57,000 withdrawals daily, matching staking intake limits.
Service Provider Timelines:
| Provider | Withdrawal Start | Notes |
|---|---|---|
| Coinbase | Upgrade + 24 hours | Immediate release post-chain confirmation. |
| Lido | Mid-May 2023 | Awaiting protocol security upgrades. |
| Rocket Pool | Post-"Atlas" upgrade (April 18) | Requires additional infrastructure updates. |
Post-Upgrade ETH Selling Pressure Breakdown
Liquidity and Stake Distribution
- Liquid Staking Derivatives (LSDs): 60.3% of staked ETH (via Lido, Coinbase, etc.) already has liquidity, reducing immediate sell incentives.
Locked ETH: 40% (non-LSD stakers) may face sell pressure upon unlocking. Nansen estimates:
- Profitable Addresses: 59% (3.62M–4M ETH) could partially or fully withdraw.
- Projected Sales: 1.2M–3M ETH, throttled by daily withdrawal limits.
Three-Phase Sell Pressure Model
Phase 1 (First 27 Hours):
- Partial Withdrawals (Interest): 84,000–125,000 ETH/day.
Phase 2 (Days 3–4):
- Peak Pressure: 136,000 ETH (partial) + 173,000 ETH (full) daily.
Phase 3 (Weeks 3–8):
- Residual Full Withdrawals: 48,000–53,000 ETH/day.
Market Impact: Daily exchange inflows could spike to 15–55% above the 30-day average (313,533 ETH), potentially suppressing prices for 3–8 weeks.
Long-Term Staking Growth
- Current Staking Rate: ~15% (vs. 50–70% for typical PoS coins).
- Post-Upgrade Potential: 2–4x increase as withdrawal certainty attracts new stakers.
