The Ethereum Merge stands as one of the most pivotal developments in the evolution of blockchain technology. Long anticipated and meticulously planned, this transition marks a fundamental shift in how the Ethereum network operates—moving from an energy-intensive proof-of-work (PoW) model to a more efficient and sustainable proof-of-stake (PoS) consensus mechanism. While the change is profound behind the scenes, its immediate impact on everyday users may be subtle. However, understanding what the Merge entails—and how to stay secure during and after the transition—is essential for every Ethereum holder, especially those using hardware wallets like Ledger.
This guide breaks down everything you need to know about the Ethereum Merge, from its technical foundation to practical safety tips and long-term implications.
Understanding the Ethereum Merge
At its core, the Ethereum Merge refers to the integration of Ethereum’s existing mainnet with the Beacon Chain, a parallel PoS blockchain launched in December 2020. The result? A unified Ethereum network that secures transactions through staking rather than mining.

Ending the Era of Proof-of-Work
Ethereum previously relied on proof-of-work (PoW), a consensus model where miners compete to solve complex mathematical problems to validate blocks. While secure, PoW demands massive computational power and electricity, leading to environmental concerns and scalability limitations.
As more users joined the network, transaction fees spiked and processing times slowed—highlighting Ethereum’s struggle to balance decentralization, security, and scalability, often referred to as the blockchain trilemma.
Welcoming Proof-of-Stake
With the Merge, Ethereum transitioned fully to proof-of-stake (PoS). In this model, validators are chosen to propose and attest to new blocks based on the amount of ETH they stake—typically 32 ETH to run a full node. This eliminates the need for energy-guzzling mining rigs and drastically reduces the network’s carbon footprint.
More importantly, PoS lays the groundwork for future upgrades aimed at improving speed, reducing costs, and enhancing overall network performance. Though these enhancements won’t arrive immediately post-Merge, they represent a critical step toward Ethereum’s vision of becoming a scalable, secure, and sustainable platform for decentralized applications.
When Did the Merge Happen?
The Merge officially occurred on September 15, 2022. It was triggered automatically once the network reached a predetermined total difficulty threshold—approximately 58,750,000,000,000,000,000,000 hashes—marking the final block produced under PoW.
From that point forward, Ethereum began operating exclusively under PoS. Users could track the exact timing via real-time tools that monitored network difficulty growth.
What Does the Merge Mean for You?
For most users, the transition was seamless. There was no need to take action, migrate funds, or upgrade wallets. Your ETH, tokens, and NFTs remained safe and fully functional throughout the process.
However, while the user experience remained unchanged, awareness and caution became more important than ever—especially in light of rising scam attempts exploiting confusion around the event.
Key Security Reminders
To protect yourself during major network transitions like the Merge:
- Never share your 24-word recovery phrase. No legitimate service, including Ledger, will ever ask for it.
- No migration is required. Your funds do not need to be transferred, synchronized, or upgraded.
- Ignore “ETH2” airdrop offers. The Merge was not an airdrop. Any promise of free coins is likely a scam.
- Keep assets in your Ledger wallet. It is completely safe to store ETH, ERC-20 tokens, and NFTs in your Ledger device.
- Avoid high-value transactions during transition periods. As a precaution, delay large transfers or trades until network stability is confirmed.

Can You Stake ETH After the Merge?
Yes—after the Merge, users who hold 32 ETH or more can become solo validators by staking their funds directly on the network. Validators play a crucial role in securing Ethereum by proposing new blocks and verifying others’ work. In return, they earn passive rewards in ETH.
However, solo staking comes with responsibilities:
- Validators must maintain constant uptime.
- They must keep software updated.
- Misbehavior or downtime can lead to penalties—a process known as slashing, which results in partial loss of staked ETH.
While Ledger Live did not support direct solo staking immediately after the Merge, comprehensive guides are available through official sources like ethereum.org for those interested in setting up their own validator node.
Staking Without 32 ETH
Don’t have enough ETH to run a full node? No problem. Platforms like Lido and Rocket Pool allow users to participate in staking with smaller amounts. These services pool user funds and issue liquid staking derivatives—such as stETH—that represent staked value while remaining tradable.
If you hold stETH tokens in your Ledger wallet:
- You do not need to take any action.
- The Merge does not affect Lido or stETH functionality.
- Rewards continue accruing daily.
- The price of stETH remains pegged to ETH.
What Happened After the Merge?
The Merge was not an endpoint—it was a foundation. Since 2022, Ethereum has continued evolving through a series of upgrades designed to improve scalability, security, and usability.
One of the most significant post-Merge upgrades came in May 2025 with Pectra, a comprehensive hard fork that implemented 11 Ethereum Improvement Proposals (EIPs). These changes enhanced wallet interoperability, improved validator operations, and streamlined user interactions across dApps.
While the Merge enabled PoS, upgrades like Pectra build upon that foundation—bringing Ethereum closer to its goal of becoming a high-performance blockchain capable of supporting global-scale decentralized applications.
Frequently Asked Questions (FAQ)
Q: Do I need to do anything to prepare for the Ethereum Merge?
A: No action was required. The transition was automatic and seamless for users. Your funds remained safe without any need for migration or updates.
Q: Did I receive new coins or tokens after the Merge?
A: No. The Merge was not a fork or airdrop. There is no new “ETH2” token. If someone claims otherwise, it’s likely a scam.
Q: Can I stake my ETH using my Ledger device?
A: Yes—through third-party liquid staking services like Lido or Rocket Pool available in Ledger Live. Direct solo staking (32+ ETH) requires running your own validator node.
Q: Is my stETH affected by the Merge?
A: No. stETH holdings were unaffected. You continue earning rewards as before, and the token remains fully usable.
Q: Was the Merge safe for my crypto?
A: Yes—the network transition was thoroughly tested. As long as you kept your private keys secure and avoided scams, your assets were never at risk.
Q: What comes next for Ethereum after the Merge?
A: Future upgrades focus on scalability (e.g., sharding), faster transaction finality, and improved developer tools—all built on the PoS foundation established by the Merge.
