The world of NFTs is fast-paced, competitive, and often unforgiving—especially when it comes to minting high-demand digital collectibles. On May 1, the Otherside mint triggered a massive gas war that lasted nearly three hours, pushing Ethereum gas fees to staggering levels—peaking at over 8,000 Gwei. Many users failed to complete their transactions, while others ended up paying more than 2 ETH in gas fees just to secure a single NFT. In response, Yuga Labs announced it would refund gas fees to users whose transactions failed.
This event wasn’t just a spike in network congestion—it was a full-scale digital battlefield. For those trying to mint NFTs during such high-traffic events, emotions run high: panic, anxiety, and frustration become part of the user experience. But with the right knowledge and tools, you can dramatically increase your chances of success.
Drawing from insights by @thedigitalvee and practical Ethereum mechanics, this guide will walk you through everything you need to know to win a gas war—from understanding transaction fees to optimizing your MetaMask settings for faster confirmations.
What Is a Transaction Fee on Ethereum?
When you interact with the Ethereum blockchain—whether minting an NFT, swapping tokens, or transferring ETH—you must pay a transaction fee. Since the EIP-1559 upgrade, this fee is composed of two key components:
- Base Fee: Automatically set by the network based on congestion.
- Priority Fee (Tip): A voluntary amount you add to incentivize miners (or validators) to prioritize your transaction.
Total Transaction Cost = Base Fee + Priority Fee
The base fee is burned (removed from circulation), while the priority fee goes directly to the validator. Your goal during a gas war is to strategically balance these two components to ensure your transaction gets processed quickly—without overpaying unnecessarily.

How to Optimize Gas Settings During an NFT Mint
Most users rely on default MetaMask suggestions—but during high-demand mints, those defaults are almost guaranteed to fail. To stay ahead, you need to manually adjust your gas settings.
Start by enabling Advanced Gas Controls in MetaMask. This unlocks critical options: Max Fee and Priority Fee.
Here’s what each means:
- Max Fee: The upper limit you’re willing to pay per unit of gas.
- Priority Fee: The tip you offer validators for faster processing.
Now, let’s explore three common strategies—and why only one truly works.
Strategy 1: Only Increase the Max Fee
Raising just the Max Fee does little good. It allows room for rising base fees but caps your priority fee at default levels (often 1.5–2 Gwei). Validators prioritize transactions with higher tips, so if your tip stays low, your transaction lags—no matter how high your max fee is.
This approach fails because it doesn’t properly incentivize validators.
Strategy 2: Only Increase the Priority Fee
Boosting only the priority fee helps—you’re offering validators more incentive. However, there’s a catch: if the base fee spikes after you submit your transaction, the total cost (base + priority) might exceed your max fee.
When that happens, the system automatically reduces your priority fee to stay within limits—defeating the purpose of increasing it in the first place.
Strategy 3: Increase Both Max Fee and Priority Fee
This is the winning strategy.
By raising both values, you:
- Account for potential increases in base fees.
- Guarantee a competitive tip for validators.
- Avoid automatic downgrades due to exceeding your max fee.

How Much Should You Pay? Conservative vs. Aggressive Tactics
Now comes the critical question: How high should you set your fees? There are two proven approaches.
The Conservative Method: Use Blocknative’s Gas Estimator
Blockchain analytics platform Blocknative recommends a smart formula for predictable results:
Max Fee = (2 × Current Base Fee) + Priority Fee
This method assumes base fees could double during peak demand. Using Blocknative’s Gas Estimator with the “99% probability” setting gives you strong odds of confirmation within six consecutive blocks.
For example:
- Base Fee: 300 Gwei
- Priority Fee: 50 Gwei
- Max Fee: (2 × 300) + 50 = 650 Gwei
This approach balances cost and reliability—ideal for cautious minters.
The Aggressive Method: Maximize Speed at Any Cost
If securing the NFT is non-negotiable (e.g., a rare genesis drop), go all-in.
Set both your Max Fee and Priority Fee to the same high value. This ensures that whatever remains after the base fee is deducted goes entirely to the validator as a tip.
Example from a past MAYC airdrop:
- Base Fee: 364 Gwei
- Priority Fee: 700 Gwei
- Max Fee: 700 Gwei
- Result: Instant confirmation, total gas cost = 700 Gwei (~0.12 ETH)
While effective, this method risks overpayment. Use it sparingly—and only when the asset justifies the cost.
What to Do If Your Transaction Is Stuck?
Even with optimized settings, transactions can stall due to sudden network spikes. Here’s how to recover:
Step 1: Check Pending Transactions
Open MetaMask and go to the Activity tab. If your transaction isn’t confirmed within seconds, act fast.
Step 2: Use the “Speed Up” Feature
Click Speed Up to re-submit your transaction with a higher priority fee. MetaMask will create a replacement transaction with the same nonce but increased gas.
Step 3: Manual Acceleration (If Needed)
If the Speed Up button doesn’t appear:
- Click on the pending transaction.
- Look for a secondary Accelerate option at the bottom of the pop-up.
- Repeat as needed until confirmed.
Monitor network conditions using tools like Blocknative or Etherscan to decide how much to increase.
Frequently Asked Questions (FAQ)
Q: What causes gas wars during NFT mints?
A: Gas wars occur when thousands of users try to mint an NFT simultaneously. High demand leads to network congestion, forcing users to outbid each other with higher gas fees to get priority processing.
Q: Can I avoid paying high gas fees entirely?
A: Not completely—but you can reduce risk by minting during off-peak hours (if possible), using Layer 2 solutions, or choosing projects that implement fair-launch mechanisms like queue systems or Dutch auctions.
Q: Does increasing my Max Fee mean I’ll always pay more?
A: No. You only pay the actual base fee plus your set priority fee. The Max Fee is a ceiling—not what you necessarily pay. For example, if you set a Max Fee of 700 Gwei but the actual cost is 400 Gwei, you pay only 400.
Q: Is it safe to set very high gas fees?
A: Technically yes—but financially risky. Overpaying can cost ETH unnecessarily. Always assess whether the NFT’s value justifies potential gas overruns.
Q: Are there tools besides MetaMask for better gas control?
A: Yes. Wallets like Rabby and tools like Blocknative’s simulator offer enhanced gas optimization features. Some platforms also provide real-time alerts for network congestion.
Q: Will Ethereum’s future upgrades reduce gas wars?
A: Yes. Upgrades like proto-danksharding and increased Layer 2 adoption aim to improve scalability and lower transaction costs over time. However, short-term competition during major mints will likely persist.

Final Tips for Winning Future Gas Wars
Success in a gas war isn’t just about spending more—it’s about strategic spending. Understand the mechanics, test your setup before major drops, and use reliable tools to monitor network health.
Remember:
- Always enable Advanced Gas Controls.
- Set both Max Fee and Priority Fee wisely.
- Be ready to accelerate if needed.
- Use data-driven tools like Blocknative for accurate estimates.
With practice and preparation, you can turn chaos into opportunity—and secure coveted NFTs without losing your shirt in gas fees.
