EIP-1559 went live on August 5, 2021, as part of the London Hard Fork, and dispelled initial fears—there was no chain split, price crash (ETH actually rose 4%), or miner-led fork. Instead, it revolutionized Ethereum’s fee market by introducing a burn mechanism for base fees and allowing users to specify max fees and priority tips instead of gas prices.
How EIP-1559 Transforms Ethereum’s Fee Structure
Under EIP-1559, transaction fees are calculated as:
Transaction Fee = BaseFee + min(MaxFee - BaseFee, PriorityFee)
| Component | Description |
|---|---|
| BaseFee | Dynamically adjusts based on network congestion. Burned (destroyed) rather than paid to miners. |
| PriorityFee | A "tip" to incentivize miners to prioritize transactions. |
| MaxFee | The maximum fee a user is willing to pay. Excess beyond (BaseFee + PriorityFee) is refunded. |
Pre-EIP-1559: The Auction Model
Before EIP-1559, Ethereum relied on a first-price auction model:
- Users bid gas prices for transactions.
- Miners prioritized higher-paying transactions, often leading to overpayment or long delays.
- Fees were unpredictable during peak demand (e.g., NFT drops, ICOs).
Key Goals of EIP-1559
Predictable Fees:
- Fixed "base fee" per block, adjusted algorithmically.
- Wallets like MetaMask can estimate costs more accurately.
Reduced Latency:
- Blocks can temporarily expand to 200% capacity (e.g., from 12.5M to 25M gas).
- Transactions with fees above the base fee are typically included within a few blocks.
Network Equilibrium:
- Base fee increases if block utilization >50%; decreases if <50%.
- Smooths out demand spikes and prevents overpayment.
Deflationary Pressure:
- Burning the base fee reduces ETH supply, potentially increasing its value.
Common Misconceptions
❌ "EIP-1559 lowers gas fees."
- Truth: It optimizes fee transparency and predictability—not necessarily price.
- ✅ Real solutions for lower fees: ETH 2.0 (PoS) and Layer 2 scaling (e.g., Optimism, Arbitrum).
FAQs
Q: Does EIP-1559 eliminate gas fees entirely?
A: No—it restructures fees to be more efficient and transparent.
Q: How often does the base fee adjust?
A: Every block (~12-15 seconds), responding to real-time demand.
Q: Why burn the base fee instead of paying miners?
A: To align incentives—miners still earn tips, while ETH holders benefit from reduced supply.

Bottom Line: EIP-1559 is a foundational upgrade for Ethereum’s fee market, balancing user experience, miner incentives, and ETH’s economic model. While it doesn’t solve scaling alone, it paves the way for ETH 2.0’s broader vision.
