The Great Change in ETH Gas Fees in 2025: The Truth Behind the Drop from 86 USD to 0.39 USD

Why has Ethereum suddenly become cheaper?

If you have recently been trading on Ethereum, you may have noticed a crazy phenomenon: the gas fees in your wallet have dropped exponentially. A simple swap that used to cost $86 now only costs $0.39. NFT minting fees have dropped from $145 to $0.65. This is not an illusion — the Dencun upgrade has caused seismic changes in the Ethereum ecosystem this year.

Data Speaks: 2024 vs 2025

The most intuitive comparison:

• Average gas price: It plummeted from 72 gwei in 2024 to 2.7 gwei in 2025.
• Decline: An astonishing drop of 95%
• Simple transfer cost: Cut off a zero from the historical high.

What does this mean? Users can finally stop hesitating for half a day over a transaction of 0.01.

What is Gas? Why do we have to spend money?

Think of gas as the "energy value" of Ethereum. Every operation - transfer, contract interaction, minting NFTs - consumes computing power, and this computing power needs to be compensated with money for the validators.

Why set this threshold?

• Anti-spam: No cost, miners might be overwhelmed by spam transactions.
• Incentive Mechanism: Encourage validators to maintain network security
• Market Pricing: During network congestion, transactions willing to pay higher gas fees are prioritized for inclusion on the blockchain.

What is Gwei? Gwei = one billionth of an ETH (0.000000001 ETH). This unit name comes from the cryptographer Wei Dai—one of the founding theorists of Bitcoin.

How EIP-1559 Changed the Game Rules

The current gas fee consists of two parts:

Base Fee + Tip = Total Cost

Base Fee: The minimum threshold automatically adjusted by the network.

• During congestion ↑, during free time ↓
• Key: The base fee is burned, directly reducing the circulating ETH (inflation offset)

Tip (Priority Fee): The reward you give to the validator

• Want to speed up? Tip more.
• No rush? Just meet the minimum standard.

Actual calculation example

Scenario: Transfer 1 Ether to another wallet

• Gas consumption: 21,000 units (fixed value)
• Base fee: 10 gwei
• Tip: 2 gwei

Calculation: 21,000 × (10 + 2) = 252,000 gwei = 0.000252 ETH ≈ 0.7 USD

Compared to the $15-30 cost for the same operation in 2024, this is indeed a qualitative leap.

When is gas the cheapest? Practical data

Not all time periods are the same. On-chain activities show regularity:

Cheapest Time Period

• Weekend (especially Saturday and Sunday): 25-40% cheaper than weekdays
• 2-6 AM (UTC): Ghost town level low prices
• During a bear market: the base fee maintains the floor price

The most expensive period

• Tuesday to Thursday working hours: DeFi farmers and traders gather
• When major events happen: new projects launch, NFT craze, market surges and plummets
• When a big player sweeps the floor on the chain: a gas bidding war breaks out

Strategy Suggestion: Non-urgent operations should be postponed until the weekend or late at night, which can save more than 50%.

Is there anything cheaper than L1? Yes—Layer 2

Although the Ethereum main chain is already very cheap, the Layer 2 network is the real "free lunch":

| Network | Gas Cost Comparison | Features | |------|----------|------| | Arbitrum | 90-95% cheaper | Most mature ecosystem, most comprehensive DeFi applications | | Optimism | 90-99% cheaper | Officially prioritized support, top-notch security | | Polygon | 95%+ cheaper | Independent sidechain, different security model |

Most mainstream DeFi projects (Uniswap, Aave, Curve) are launched on L2. If you are still farming on the mainnet, it means you are not fully utilizing the ecosystem.

How to reduce Gas fees by another 50%?

1. Time Strategy (Simplest)

Use the real-time dashboard of Etherscan or ETH Gas Station to lock in the green zone (low price period) to execute trades.

2. Batch Operations (Save Most)

Pack multiple operations into a single transaction:

• Swap + Transfer + Authorization → One transaction completed
• Standard method: 3 independent transactions
• Save: 60-70% gas

3. Wallet Optimization

Don't overlook the "Custom Gas" option in wallets like MetaMask:

• Don't rush: select "Slow"
• Normal: Select "Standard"
• Urgent: Select "Fast"

Many people default to clicking "Quick", which is a suicidal premium.

4. Escape the mainnet (fundamental)

For daily operations:

• Small Transactions → Layer 2
• Large amount deposit → Batch cross-chain
• Long-term holding → Consider L1 alternatives like Solana, Sui

Will it continue to be cheap in the future?

Official Roadmap Signal:

• Pectra Upgrade (Postponed): Further optimization of L2 + Mainnet
• Sharding Long-term Plan: Mainnet throughput may increase by more than 10 times.
• Competitive Pressure: Solana and other L1s are eyeing closely, Ethereum must maintain fee competitiveness.

In the short term (2025): It is expected that gas will remain in a comfortable range of 2-5 gwei, unless a black swan event occurs (such as a crazy outbreak of NFTs/DeFi).

Long-term (2026+): The Layer 2 ecosystem further matures, and the mainnet gas may become the choice of "advanced users and large holders."

Summary: What You Should Do

✅ Bookmark Etherscan Gas Tracker and ETH Gas Station ✅ Execute non-urgent transactions on weekends ✅ If it can be done on L2, don't go on the mainnet. ✅ Learn the "Custom Gas" option in the wallet ✅ Follow the subsequent upgrade trends of Dencun

Ethereum has transformed from a "noble network" to a "common network". Now, there's no need to spend an entire afternoon worrying about transactions of 0.5 coins. But this also means more people are flooding in, and the ecosystem is becoming more crowded—an eternal trade-off.
