Ethereum core developers have confirmed in a recent call that the highly anticipated "Shanghai Upgrade," the first major hard fork since The Merge, is scheduled for implementation in March. A key feature of this upgrade is the activation of staking withdrawals from the Beacon Chain, which has been prioritized by developers. With ETH's price significantly higher than the $400 level it was at when staking first began over two years ago, many are questioning whether this unlock could create substantial selling pressure.
What is the Shanghai Upgrade?
The Shanghai Upgrade is a critical hard fork for the Ethereum network, focusing on several core improvements. Based on developer discussions, a few key points have emerged.
Scheduled for March Implementation
While a specific date for the Shanghai hard fork had remained uncertain, developers have now solidified the priority of features to be included. This has allowed them to set a target release window for March.
Staking Withdrawals Are the Top Priority
The introduction of EIP 4895, which will enable staking withdrawals from the Beacon Chain, has been designated as the highest-priority item for this upgrade. The Ethereum mainnet deposit contract originally went live on November 4, 2020, but users have been unable to withdraw their staked ETH or rewards for over two years. This upgrade will finally change that.
Inclusion of EVM Object Format (EOF)
Developers have tentatively agreed to include the EVM Object Format (EOF) in the Shanghai Upgrade. This constitutes a major upgrade to the Ethereum Virtual Machine (EVM) and includes the following proposals:
- EIP 3540
- EIP 3670
- EIP 4200
- EIP 4570
- EIP 5450
Features Postponed to a Fall Upgrade
The developer community has noted that if the EVM Object Format proves too complex and consensus cannot be reached, its implementation will be delayed until a major upgrade planned for the fall.
Similarly, EIP-4844, also known as proto-danksharding, which is viewed as a crucial step for massively improving scalability, has been postponed to this autumn upgrade. In November, Liam Horne, CEO of OP Labs, emphasized that EIP-4844 had undergone over nine months of iteration and could potentially reduce Ethereum fees by 100x. Ethereum co-founder Vitalik Buterin has stated that EIP-4844 is the first step toward drastically lowering Layer 2 fees, making DApps more affordable and accessible for a broader user base.
Analyzing the Potential for Selling Pressure
The Beacon Chain deposit contract currently holds a massive 15.58 million ETH. At current valuations, this equates to nearly $20 billion in staked assets.
Given that ETH was trading around $400 when staking initially opened, a portion of these stakers are sitting on significant unrealized profits, in some cases exceeding 200%. This has led to market concerns about a potential sell-off once withdrawals are enabled.
However, several factors may mitigate immediate selling pressure. The rise of liquid staking has become a dominant trend. Data indicates that Lido alone operates nearly a third of all Ethereum validator nodes. Furthermore, major exchanges like Coinbase and Binance offer their own staking services with liquid tokens like cbETH and BETH. This means a large number of users already have the ability to gain liquidity and exit their staked positions without waiting for the official unlock, as these tokens are traded on the open market.
Additionally, the Ethereum protocol has a built-in mechanism that prevents a sudden, mass exodus of validators. The withdrawal process is gradual and orderly. The network processes exits in sequences called epochs, which occur every 6.4 minutes. In each epoch, only 4 to 6 validators can fully exit, depending on the total number of active validators. Even if every validator decided to exit simultaneously, it would take several months for the process to complete, preventing a sudden flood of ETH onto the market.

Frequently Asked Questions
What is the single most important feature of the Shanghai Upgrade?
The foremost feature is the activation of staked ETH withdrawals via EIP-4895. This allows users and validators who have locked their ETH in the Beacon Chain since 2020 to finally withdraw their assets and accrued rewards.
Could the Shanghai Upgrade cause the price of ETH to drop?
While there is concern that unlocked ETH could be sold, the actual market impact is likely tempered by the gradual withdrawal process and the pre-existing liquidity provided by liquid staking tokens. Many stakers are long-term believers who may not sell immediately.
How long will it take to withdraw staked ETH after the upgrade?
Withdrawals are not instantaneous. They are processed slowly over time by the protocol. If you initiate a withdrawal, it will be queued. The time it takes to complete depends on how many others are in the queue ahead of you, but the system is designed to handle exits over months, not days.
What is EIP-4844 and why was it delayed?
EIP-4844, or proto-danksharding, is an upgrade designed to significantly reduce transaction fees on Layer 2 networks. It was delayed to ensure the Shanghai Upgrade could focus on the critical withdrawal functionality without overcomplicating the hard fork.
Do I need to do anything if I am staking?
If you are staking directly as a solo validator, you will need to initiate a withdrawal. If you are using a liquid staking service or a centralized exchange, they will manage the process for you, and you should follow their specific instructions.
Is my staked ETH safe during the upgrade?
The upgrade is a carefully coordinated hard fork. While all upgrades carry some inherent risk, the Ethereum developer community conducts extensive testing to ensure the security and smooth transition of the network.
