What Is EIP-1559? Definition & Background
Ethereum EIP-1559, formally known as Ethereum Improvement Proposal 1559, introduced a major redesign to Ethereum’s transaction fee market in 2021. An "EIP" is simply a suggestion for network improvements, discussed and (sometimes) adopted by the Ethereum community and developers. EIP-1559 specifically set out to overhaul how users pay for Ethereum transactions, and how those fees impact the network and its monetary policy.
Previously, Ethereum faced notorious issues: transaction fees would surge during network congestion, creating nasty surprises for users and degrading the experience. EIP-1559 was crafted to bring fairness, predictability, and transparency to Ethereum’s fee market.
Ethereum needed this upgrade because unpredictable transaction fees made it challenging for everyday users and developers to plan ahead. During high demand, fees could skyrocket, pricing out smaller users or leaving them guessing what to pay. By introducing a new fee structure (including the novel burn mechanism), EIP-1559 aimed to smooth out these spikes and provide a less stressful, more reliable transaction experience.

Why Did Ethereum Introduce EIP-1559?
Before EIP-1559, users often faced a confusing and stressful process when sending ETH or tokens. Imagine competing in a delivery service auction for a package slot: only the highest bidder’s transaction would go through quickly, while everyone else risked delays or overpaying. This led to wild fee swings and wasted money. By introducing a transparent, algorithm-driven fee structure, EIP-1559 aimed to end these chaotic bidding wars and support Ethereum’s growing ecosystem.
How Did Ethereum Gas Fees Work Before EIP-1559?
Before EIP-1559, Ethereum relied on a simple but often problematic system called the "first-price auction" for handling transaction fees. Users would choose how much gas (a unit of computational work) they were willing to pay (the gas price), and those willing to pay the most would be prioritized by miners. This meant you often had to bid higher than others just to ensure your transaction was included promptly.
This auction model became notoriously volatile. If congestion spiked—due to a hot NFT launch or popular token sale—transaction fees (gas prices) soared, hitting $50, $100, or even more for routine transfers. Many users were forced to either overpay dramatically or risk having their transactions stuck for hours, sometimes with no refund if the transaction eventually failed.
This unpredictability led to a frustrating, often opaque user experience. You never quite knew how much to pay for a transaction—or whether your transaction would succeed at all. The network felt unpredictable, which slowed adoption and eroded trust among new users. Platforms like OKX provided detailed historical ETH fee data to help showcase just how wild these swings could get.
The Auction Model Explained
In the old model, miners prioritized transactions offering the highest fees—a bidding war. Imagine 1,000 people vying for 100 seats on a flight: only those who bid the most got on. Others waited, paid more, or missed out. Users routinely overbid just to avoid being left behind. This meant massive swings in transaction costs from one moment to the next.
| Fee Model | User Experience | Typical Cost (High Congestion) |
|---|---|---|
| First-Price Auction | Chaotic, unpredictable | $50–$200+ |
| Post-EIP-1559 | Predictable, fairer | ~$10–$50 |
The EIP-1559 Fee Mechanism: Base Fee, Tips & Fee Burn
With EIP-1559 explained, let’s look at the core fee mechanism that revolutionized Ethereum: the introduction of the base fee, priority tips, and the fee burn process.
How the Base Fee Works
Under EIP-1559, each Ethereum block now includes a base fee—an algorithmically set minimum fee that everyone must pay. This base fee rises or falls automatically based on how full recent blocks are. If demand increases, the base fee rises by up to 12.5% per block; if demand drops, the fee falls at the same rate. This ensures fees adjust smoothly to network conditions, not just user guesses.
On top of the base fee, users can add a priority tip to incentivize miners or validators to include their transaction sooner, especially when they need rapid confirmation. The base fee, however, is not paid to miners—it is now burned, permanently removing it from Ethereum’s supply and making ETH scarcer over time.
OKX incorporates this model in its ETH withdrawal process, showing users a detailed EIP-1559 breakdown of base fees and tips.
Worked Example: Old vs. New Fee Calculation
Suppose you want to send a token during medium network demand:
| Scenario | Total Fee Paid | Fee to Miners | Fee Burned | Notes |
|---|---|---|---|---|
| Pre-EIP-1559 | 0.025 ETH | 0.025 ETH | 0 ETH | All fee goes to miner |
| Post-EIP-1559 | 0.018 ETH | 0.002 ETH¹ | 0.016 ETH | Base fee burned; tip only |
¹Only the tip (priority fee) goes to the miner/validator; the larger base fee is burned every block.
In summary, the new model makes transaction fees both more predictable for users and deflationary for ETH supply.
Impact on Ethereum Users: Cheaper, Predictable Fees?
For most Ethereum users, the biggest impact of EIP-1559 was greater predictability and fairness in gas fees. Since the base fee is set algorithmically based on block demand, users no longer need to second-guess or overbid just to secure a transaction. The oscillations in gas fees have been dampened, making it much easier to estimate costs before hitting send.
On average, while transaction fees have not always been drastically cheaper, surprise spikes are far less common. For example, sending ETH might have cost anywhere from $20 to $150 pre-upgrade; now, costs are more likely to fluctuate between $10 and $40 depending on congestion.
In edge cases, like high-traffic NFT drops, fees can still rise if many transactions compete for limited block space, but the increases are more predictable and less prone to extreme outliers. Users can also utilize the priority tip for urgent transactions, paying a bit extra for speed.
OKX integrates a fee preview tool in all swap and send ETH screens, giving users clear insight into EIP-1559 fees and helping them set realistic expectations for transaction costs.

ETH Burn & Monetary Policy: Does EIP-1559 Make ETH Deflationary?
A core component of EIP-1559 is the fee burn mechanism. Every block, the base fee portion from all included transactions is burned—effectively destroyed—reducing the total circulating supply of ETH in real time. Since launch, more than 3 million ETH (worth billions of USD) has been burned and permanently removed from the network.
The question of deflation comes down to whether more ETH is burned through fees than is newly issued as block rewards (to validators or miners). If network activity is high and many transactions are paying large base fees, more ETH is burned than is being created, and ETH becomes net deflationary for that period.
This has had a notable effect on ETH’s economic narrative, bolstering its reputation as a "store of value" or even "ultrasound money." When the burn outpaces new supply, holders see their relative ownership of ETH increase over time.
OKX provides real-time ETH burn trackers and supply charts, helping users monitor how EIP-1559 is shaping ETH’s monetary policy minute by minute.
Impact on Ethereum Miners: Rewards, Incentives & Network Security
EIP-1559 brought significant changes for miners (and, after the Merge, validators). Before the upgrade, miners received all transaction fees as well as block rewards. After EIP-1559, miners receive only the tips; the much larger base fee portion is burned.
This shift drew some opposition among mining pools, who argued it reduced their earnings and could harm network security by weakening incentives. For a period, miner revenue from fees dropped, increasing reliance on block rewards and tips, especially during periods of low congestion.
Nevertheless, after EIP-1559—and subsequently, ETH’s transition to proof-of-stake—the network adjusted. Fees became more predictable, average miner/validator earnings stabilized (though with lower peaks), and network security remained robust.
OKX actively publishes guides and resources to help both users and miners understand evolving reward structures after major Ethereum upgrades like EIP-1559.
Rollout Timeline & The London Hard Fork
EIP-1559 was deployed as part of Ethereum’s much-anticipated London Hard Fork at block 12,965,000 on August 5, 2021. The London upgrade bundled several key improvements—notably EIP-1559—meant to make the network more user- and developer-friendly ahead of its merge to proof-of-stake.
Other major proposals in the London Hard Fork included EIP-3198 (base fee access for contracts) and EIP-3529 (gas refund changes). Adoption was rapid: nearly all major clients, wallets, and exchanges supported the change right away, and the consistency of block inclusion improved noticeably post-upgrade.

Comparing EIP-1559 to Other Blockchains & Fee Models
While EIP-1559 is unique to Ethereum, similar fee models have started appearing on other blockchains. For instance, Bitcoin still uses a simple first-price auction: you outbid everyone else, and your payment goes to miners, with no burn or base fee mechanism. As a result, Bitcoin fees can be harder to predict during periods of congestion.
Other EVM-compatible chains like Polygon and BNB Chain have implemented EIP-1559-style fee structures, including base fees and token burns, to improve fee predictability and reduce supply inflation.
Layer 2 networks (like Arbitrum or Optimism) sometimes integrate EIP-1559 logic, but fees are generally much lower and do not always contribute to the ETH mainnet burn. OKX offers robust support for EIP-1559-compatible assets across multiple chains, making gas management more consistent for users.
| Chain | Base Fee? | Token Burn? | Fee Predictability | EIP-1559 Adopted |
|---|---|---|---|---|
| Ethereum | Yes | Yes | High | Yes |
| Bitcoin | No | No | Low | No |
| Polygon | Yes | Yes | High | Yes |
Advanced: EIP-1559 Simulations & Visuals
To really grasp EIP-1559’s behavior, let’s simulate how the base fee responds to changing network congestion. Imagine a sequence of five blocks, starting with a moderate base fee:
| Block | Usage (%) | Base Fee (Gwei) | Adjustment (%) | New Base Fee |
|---|---|---|---|---|
| 1 | 50 | 30 | — | 30 |
| 2 | 100 | 30 | +12.5% | 33.75 |
| 3 | 120 | 33.75 | +12.5% | 37.89 |
| 4 | 60 | 37.89 | –12.5% | 33.20 |
| 5 | 50 | 33.20 | –12.5% | 29.05 |
In this scenario, heavy congestion quickly lifts the base fee, discouraging spam and helping the network stabilize. As congestion falls off, the base fee drops, making transactions cheaper in quieter periods.
