Ethereum stands as one of the most influential blockchain platforms in the world, powering a vast ecosystem of decentralized applications (DApps), smart contracts, and digital assets. As the second-largest cryptocurrency by market capitalization, Ethereum often draws comparisons to Bitcoin—especially when it comes to supply mechanics. But unlike Bitcoin’s hard cap of 21 million coins, Ethereum operates under a different economic model. So, how many Ethereum are actually in circulation? And what mechanisms control its issuance?
This article explores Ethereum's supply dynamics, including current issuance levels, inflation controls, and the long-term impact of network upgrades like the shift to Proof-of-Stake (PoS).
Current Ethereum Circulating Supply
As of early 2025, the total circulating supply of Ethereum (ETH) is approximately 120 million ETH. This number fluctuates slightly due to ongoing issuance from block rewards and network activity. Unlike Bitcoin, which has a predetermined maximum supply, Ethereum does not enforce a fixed upper limit on its total coin count.
Instead, Ethereum's issuance is governed by protocol rules that adjust based on network consensus and upgrades. The supply grows incrementally with each new block added to the blockchain, though recent changes—especially the transition to PoS—have significantly reduced the rate of new ETH creation.

How Ethereum Issuance Works
Ethereum’s supply is primarily influenced by two core mechanisms: block rewards and network usage, particularly through transaction fees (also known as gas fees). Let’s break these down.
Block Rewards and Inflation Control
In the early days of Ethereum, miners received 5 ETH for every successfully mined block under the Proof-of-Work (PoW) consensus mechanism. This generous reward helped bootstrap network security and miner participation.
However, with the Byzantium hard fork in 2017, this reward was reduced to 3 ETH per block. Later adjustments further lowered incentives, especially after Ethereum’s historic shift to Proof-of-Stake (PoS) in September 2022—commonly referred to as "The Merge."
Under PoS:
- Validators (rather than miners) secure the network.
- New ETH is issued as staking rewards.
- Annual issuance dropped dramatically—from over 4% inflation annually under PoW to roughly 0.5% to 1% today.
This makes Ethereum’s monetary policy more deflationary-friendly, especially when combined with fee-burning mechanisms introduced in EIP-1559.
Gas Fees and Supply Dynamics
Another critical factor shaping Ethereum’s economic model is gas fees—the cost users pay to execute transactions or deploy smart contracts.
With the implementation of EIP-1559, a portion of every transaction fee is permanently burned (removed from circulation). This means:
- High network demand leads to more fees burned.
- If fee burn exceeds new ETH issuance, the net supply can actually decrease, resulting in deflationary pressure.
For example, during periods of high activity—such as NFT mints or DeFi launches—thousands of ETH can be burned daily. In several months since 2022, Ethereum has experienced net deflation, making it one of the few major cryptocurrencies with a potentially shrinking supply over time.

Key Factors Influencing Ethereum Supply
While there's no pre-set cap like Bitcoin’s 21 million, Ethereum’s supply is far from uncontrolled. Several built-in mechanisms work together to regulate issuance and promote long-term sustainability:
1. Staking Rewards in PoS
Validators who stake ETH (minimum 32 ETH) earn rewards for proposing and attesting to blocks. However, these rewards are algorithmically adjusted based on:
- Total amount of ETH staked across the network.
- Network efficiency and uptime.
The more ETH that is staked, the lower the individual reward rate—this self-adjusting mechanism prevents runaway inflation.
2. EIP-1559: Fee Burning Mechanism
As mentioned, EIP-1559 introduced a base fee that is burned with every transaction. Users also pay optional priority fees (tips) to validators. This split ensures:
- Predictable pricing for users.
- Continuous removal of ETH from circulation.
- Potential for deflation during peak usage.
Since its activation, over 4 million ETH have been burned—a testament to Ethereum’s robust on-chain economy.
3. Protocol Upgrades and Future Controls
The Ethereum development team continues to refine the network’s economic model through upgrades such as:
- The Merge (2022): Transitioned from energy-intensive mining to eco-friendly staking.
- Surge, Verge, Purge, Splurge: Roadmap phases aimed at improving scalability, data availability, and state management—all of which indirectly influence issuance efficiency.
Future proposals may introduce further refinements, such as dynamic issuance caps or enhanced burning models.
Frequently Asked Questions (FAQs)
Q: Does Ethereum have a maximum supply?
No, Ethereum does not have a fixed maximum supply like Bitcoin. Instead, its supply is managed through dynamic issuance and deflationary mechanisms such as staking rewards and fee burning.
Q: Is Ethereum inflationary or deflationary?
Ethereum can be both. It has an inflationary component through staking rewards but also a deflationary component via EIP-1559 fee burning. When more ETH is burned than issued, the net supply decreases—making Ethereum temporarily deflationary.
Q: How many new ETH are created each day?
Post-Merge, around 1,600 to 1,800 ETH are issued daily as staking rewards. However, this number varies depending on total staked ETH and network conditions.
Q: Can Ethereum become scarce?
Yes. Due to consistent fee burning during high-usage periods and limited new issuance, Ethereum has already entered deflationary phases. If adoption continues growing, scarcity could increase over time.
Q: What happens if I lose my private key?
Lost private keys result in permanently inaccessible funds. Since there’s no central authority to recover access, those ETH remain in limbo—effectively reducing usable supply and contributing to scarcity.
Q: Will Ethereum ever switch back to Proof-of-Work?
No. The transition to Proof-of-Stake was a permanent upgrade. There are no plans to revert to PoW, as PoS offers better energy efficiency, security, and economic alignment.
The Bigger Picture: Supply, Scarcity, and Value
Understanding Ethereum’s supply mechanics isn’t just technical—it directly impacts investor sentiment and long-term value perception.
With Bitcoin often viewed as “digital gold” due to its fixed supply, Ethereum positions itself as “programmable money”—a living financial system where monetary policy evolves with usage. Its blend of moderate inflation and potential deflation creates a unique balance between rewarding participation and preserving value.
For developers, investors, and users alike, monitoring metrics like:
- Net issuance vs. burn rate
- Staking participation
- Daily transaction volume

Conclusion
Ethereum's supply model reflects its adaptive and evolving nature. While it lacks a hardcoded maximum like Bitcoin, it employs sophisticated tools—block rewards, staking economics, and fee burning—to maintain balance and sustainability.
With over 120 million ETH in circulation and a flexible issuance system designed for resilience, Ethereum remains a cornerstone of the decentralized web. As adoption grows and upgrades continue rolling out, its supply dynamics will play a crucial role in shaping its future as both a platform and an asset.
Understanding these mechanisms empowers users to make informed decisions—whether they're building on the network, investing in ETH, or simply exploring the future of digital finance.
