Shanghai on Ethereum: How staking withdrawals are transforming the network

The Shanghai Ethereum upgrade represents one of the most significant technical changes since the 2022 Merge. Officially implemented in March 2023, this upgrade introduced the staking withdrawal feature, transforming how users interact with Ethereum validators and the cryptocurrency market.

From Proof of Work to Proof of Stake: The Context of the Shanghai Upgrade

To understand the importance of the Shanghai Ethereum upgrade, it is necessary to review the transition that occurred in September 2022. Ethereum abandoned the Proof of Work (PoW) mechanism, the same system used by Bitcoin that requires massive computational resources and significant energy consumption. With the Merge, the network implemented Proof of Stake (PoS), an alternative consensus model that allows participants to lock up their assets to validate transactions.

Before the Shanghai upgrade, those who staked could not access their locked funds. Since the launch of the Beacon Chain in December 2020, staked ETH remained frozen indefinitely, creating a liquidity constraint for validators. This restriction generated market needs that led to the development of alternative solutions.

How Ethereum Staking Works After Shanghai

Ethereum staking allows ETH holders to stake at least 32 tokens to operate as network validators. Validators receive new blocks created by other participants, verify transaction validity, and sign the block itself, thereby attesting to the integrity of the blockchain data structure.

Running a validator node requires temporarily locking up these 32 ETH. In return, participants earn rewards generated by new blocks and transaction fees. Before 2023, this participation involved a significant trade-off: the right to earn incentives in exchange for being unable to access the funds.

The Shanghai Ethereum upgrade overturned this paradigm. Now validators can freely withdraw their locked ETH, transforming staking from a permanent commitment into a more flexible and reversible form of participation.

The EIP-4895 Mechanism and Withdrawal Enablement

The Shanghai upgrade corresponds to Ethereum Improvement Proposal number EIP-4895. Ethereum Improvement Proposals (EIPs) are technical modifications proposed by the Ethereum developer community. Anyone can submit an EIP following specific formatting criteria and subject it to review by core developers and the broader community.

EIP-4895 addresses a specific issue: the lack of a mechanism to withdraw staked funds. Before its implementation, users could not access their assets regardless of circumstances. With the approval and implementation of this EIP as a mainnet hard fork in March 2023, the network added the withdrawal functionality.

Market Impact and Liquidity Dynamics

The impact of the Shanghai Ethereum upgrade on the market involves complex facets. At launch, 13.81% of the total ETH supply was locked in staking. With withdrawals enabled, a significant amount of potential liquidity was unlocked.

As of current data in February 2026, the Ethereum market shows the following parameters:

• Current price: $1,860 USD
• 24-hour change: -5.90%
• 24h trading volume: $262.03 million USD
• Circulating market cap: $224.27 billion USD
• Circulating token supply: 120,692,355 ETH

The opening of withdrawals has generated two contrasting effects. On one side, many validators gained the ability to monetize their staking investments, potentially increasing supply in the market. On the other side, staking has become more attractive to new participants due to increased flexibility, as those previously avoiding permanent fund lock-up can now do so with the option to withdraw.

Impact on Liquid Staking and Price Effects

Before the Shanghai Ethereum upgrade, liquid staking protocols were the only solution for participating in staking incentives while maintaining liquidity. These services allowed users to deposit ETH and receive derivative tokens (like stETH, rETH) usable elsewhere in the ecosystem.

With the implementation of direct withdrawal, the unique value proposition of liquid staking has diminished. Investors have less motivation to entrust their ETH to intermediaries when they can manage staking independently. Consequently, the price of liquid staking tokens might face downward pressure, as some users may redeem their positions.

At the same time, the opening of withdrawals has fostered a more dynamic and free ETH market. Validators can now respond to demand and supply fluctuations, creating natural market balances rather than artificial ones. This mechanism reduces structural constraints and allows participants to optimize their investment strategies based on real market conditions.

An Updated Perspective on Staking Adoption

Three years after its launch, the Shanghai Ethereum upgrade has solidified Ethereum as a fully operational proof-of-stake consensus platform. The withdrawal feature, along with the previous Merge, marks the completion of the transition toward an energy-efficient and scalable validation system.

For ETH holders—whether already staking, planning to stake, or simply investing—understanding the significance and implications of the Shanghai upgrade remains essential. Incentive systems, market dynamics, and earning opportunities are directly affected by this structural change. Transparency around staking mechanisms and liquidity availability enables participants to make informed decisions regarding their portfolios and participation strategies.
