Ethereum gas wars: the hidden filter for loyal NFT holders

Whoever that wallet belonged to paid eight times the cost of the asset just to acquire it. They were far from alone: gas prices rose into triple-digit Gwei territory during the event, and a meaningful share of pending transactions failed without minting a single NFT.

We do not talk about that hour enough. The cultural memory of Otherside has been compressed into the floor-price chart and the eventual post-mint cooldown. But the gas war was the moment the filter engaged. It separated, in real time, wallets that could absorb a four-figure loss on a failed transaction from wallets that could not click confirm without sweating. Whatever a collection looked like six, twelve, or eighteen months after launch, its holder distribution and its concentration of committed collectors were already being shaped in those blocks.

A gas war is not chaos. It is a brutal, mechanical filter that runs before the first holder ever appears on the leaderboard.

This is not a defense of gas wars. Burning through hundreds of dollars in priority fees to mint a JPEG is a perverse user experience. But pretending the filter does not exist — or pretending every wallet that survives it is automatically a real collector — is the kind of cope this column exists to dismantle.

How an Ethereum gas war actually works

Strip away the hype and a gas war is an auction for scarce block space. During a popular NFT mint, more transactions are trying to enter the chain than the next blocks can accommodate. The project’s contract may be ready to process thousands of claims, but Ethereum still has a limited amount of gas available per block. Everyone cannot be first.

Under EIP-1559, introduced with the London hard fork in August 2021, an Ethereum transaction has two important fee components. The base fee is determined by the protocol and is burned. The priority fee, often called the tip, is chosen by the sender and paid to the validator or block-building flow that includes the transaction. A user also sets a maximum fee, which caps what the transaction is willing to pay.

When demand rises, the base fee adjusts upward from block to block. Users who need priority compete by offering higher effective fees. The result is not merely an expensive transaction. It is a moving target. A bid that looked aggressive when the transaction was signed can become uncompetitive seconds later.

The terminology matters here. Gwei measures a gas price, not total gas spend. Total transaction cost depends on the gas price and the amount of gas the transaction uses. A simple ETH transfer may consume far less gas than a mint interaction that invokes a complicated contract, checks allowlists, assigns token IDs, and writes several storage values. Two users can therefore pay very different amounts even when their transactions carry a similar price per unit of gas.

That distinction is easy to lose when a mint is moving too quickly to follow. The practical version is simple:

• Gas price is the amount offered per unit of gas, commonly expressed in Gwei.
• Gas used is the computational work the transaction consumes.
• Total gas cost is the gas used multiplied by the applicable fee.
• A failed transaction can still consume gas and cost money if the transaction was executed and then reverted.

The last point is where the emotional damage comes from. A failed mint does not necessarily mean the wallet did nothing. The network may have processed the transaction far enough to consume computational resources before the contract rejected it, the supply ran out, or another condition caused it to revert. Ethereum does not refund the user simply because the desired NFT was not delivered.

During a mint, bots monitor pending transactions, estimate the next block’s likely base fee, and adjust their bids quickly. Human users are working with browser extensions, wallet confirmations, hardware devices, and ordinary reaction times. By the time a person notices that the transaction is stuck and tries to speed it up, the auction may have moved several blocks ahead.

The competition is also not determined by headline gas price alone. Validators and builders consider the revenue a transaction can generate and the space it occupies. A transaction with a high effective tip and a relatively modest gas footprint can be attractive compared with a more expensive contract call offering less compensation per unit of block space. The exact ordering depends on the block-building environment, but the economic pressure is consistent: transactions that pay more for scarce capacity are more likely to move forward.

When a project mints at 0.08 ETH with a hard cap of 10,000 pieces and a much larger crowd trying to claim, the auction can spiral. Gas prices can climb well beyond normal network conditions. A transaction that would ordinarily require a few dollars in fees can end up costing $50, $500, or several thousand dollars. In the Otherside case, the cost for some successful transactions rose above $40,000.

That is the gas war in its most concentrated form: not a single fee, but a feedback loop. More demand pushes the base fee higher. Higher base fees raise the cost of every competing transaction. Users increase their priority fees to protect their position. Bots resubmit and replace transactions. The mempool becomes a battlefield where speed, capital, and technical execution matter more than enthusiasm.

FCFS mints priced below market-clearing levels do not create demand. They create a tax on the desperate, funneled directly into the cost of block space.

Why projects keep creating the conditions for a war

Here is the part Discord does not want to discuss. Many high-profile drops do not accidentally create gas wars. Their launch mechanics make one likely.

The familiar pattern is straightforward. A team sets a mint price below what the market is expected to pay, announces a First-Come-First-Served model, limits the supply, and gives the community a precise launch time. The underpricing is presented as access. The market interprets it as immediate upside. A large number of wallets then tries to capture the same discount in the same few blocks.

From a project’s perspective, the attraction is obvious. A low mint price makes the collection feel accessible and creates a strong secondary-market narrative if demand appears immediately. It can also produce a memorable launch event. A chaotic mint fills social feeds, drives screenshots, and gives holders a shared origin story.

The costs are distributed less evenly.

The project may receive its intended mint revenue. Validators and builders collect more from the increase in network activity. Professional bots treat the fees as an operating expense. The casual collector pays for failed attempts, misses the supply, or decides that the entire experience is not worth repeating. The person who loses most is often the person with the least infrastructure and the least room for error.

A gas war can therefore screen wallets by more than interest. It screens for:

• available capital at the exact moment of the mint;
• willingness to risk that capital on a failed transaction;
• familiarity with fee settings and transaction replacement;
• access to fast RPC infrastructure and reliable tooling;
• the ability to keep resubmitting while the auction changes;
• tolerance for uncertainty when the final cost is not known in advance.

Those traits overlap with conviction, but they are not the same thing. A collector can care deeply about a project and still be unable to justify a $300 failed transaction. A flipper can care nothing about the community and still win several mints because the expected resale value makes the fee rational.

This is why optimized standards such as ERC-721A entered the conversation. Batch minting can reduce the gas required per token in some contract designs, particularly when one wallet mints several NFTs in a single transaction. That can improve the economics for successful users. It can also reduce the cost advantage of ordinary users relative to bots and make it easier for sophisticated participants to claim larger batches. Lower per-token gas does not remove competition for block space. It can simply allow more competition to fit into the same event.

The contract design is only one part of the equation. A project can reduce the pressure with a allowlist, a staged mint, a Dutch auction, a per-wallet cap, a queue, a claim window, or a mechanism that lets users mint over time rather than in one block. None of these approaches is automatically fair. Each moves the burden somewhere else. But a launch that treats FCFS as neutral is usually pretending not to understand its own infrastructure.

The filter thesis — and where it breaks

The clean version of the thesis says that gas wars filter for committed, capital-resilient holders. I find that thesis directionally plausible and fundamentally incomplete.

What a gas war visibly filters for is a combination of capital, wallet sophistication, and risk tolerance. Those qualities can support long-term holding, but they do not prove it. A well-funded sniper bot operated by a professional flipper will happily absorb a $500 priority fee if the post-mint floor appears likely to cover it. The wallet wins the mint. The operator sells into the first wave of demand. Provenance and community sentiment never enter the calculation.

The opposite mistake is just as common: assuming that every wallet priced out by the gas war would have become a loyal holder. Some excluded wallets would have flipped immediately. Some would have panic-sold at the first red candle. Some were only there for the discount. The gas war does not reveal a hidden population of perfect community members. It removes access from a group whose future behavior cannot be observed.

What may survive more reliably is a middle tier: collectors with enough disposable capital to absorb elevated fees without financial stress, but without the tooling or appetite to deploy industrial bot infrastructure. They mint, pay the tax, sit through the first cooldown, and become part of the cultural core that Discord later mythologizes.

That group is real, but it is not guaranteed to dominate every collection. A project’s reputation, art, roadmap, treasury management, distribution mechanics, and broader market conditions matter after the mint. So does the behavior of the wallets that won. A collection can begin with relatively patient holders and still lose them if the team misses milestones or liquidity dries up. Conversely, a chaotic mint does not make a collection incapable of developing a durable base.

The more defensible claim is narrower: mint-day mechanics influence who gets a seat at the table. That distribution can affect later floor-price behavior, but it is one input among several rather than a reliable forecast.

There is a plausible retention hypothesis here. Projects whose mint-day distribution includes fewer large bot-driven allocations, more ordinary-sized claims, and a less punishing fee environment may have a better chance of retaining engaged holders over longer periods. But that pattern should be tested collection by collection. It should not be presented as a confirmed law of NFT markets.

Wallet labels are also imperfect. One person can control multiple addresses. A single wallet can be used by a team, a syndicate, or a bot. A large batch does not automatically identify a professional flipper, and a one-token wallet does not automatically identify a loyal collector. On-chain data can show transaction behavior. It cannot read intent.

The same caution applies to failed transactions. A high failure rate may indicate that users were submitting uncompetitive bids, that the contract was poorly designed, that the supply vanished quickly, or that the launch itself was unstable. It does not, by itself, tell us that the excluded users would have held longer than the successful ones.

Still, the distributional effect is difficult to ignore. Small wallets and first-time minters are more exposed to failed attempts because one transaction can represent a meaningful share of their available capital. A professional operator may regard the same fee as a tolerable cost of inventory acquisition. The market calls both participants “holders” only after the mint. Before that, they were competing under very different constraints.

What to watch while the gas war is live

If you are deciding whether to participate — and I will assume you have already decided that the project deserves your attention — the useful data points are blunt and quantifiable.

1. The current base fee in Gwei and its direction over the last few blocks. A single high number is less informative than the trend. If the base fee is still climbing, your estimate may be obsolete before the transaction reaches a block.

2. Priority-fee bids for comparable contract interactions. A transfer and an NFT mint are not identical transactions. Compare bids for the same contract or a similar mint call where possible. If the bids required for inclusion are already several times higher than your planned setting, the auction has moved beyond your original assumptions.

3. The contract’s gas footprint. The mint price is only one part of the entry cost. A contract that uses substantially more gas per successful claim can turn an apparently affordable drop into an expensive one even before competition peaks.

4. The behavior of recent successful transactions. Look at how many tokens each wallet is claiming, whether claims are concentrated in a small number of addresses, and whether transactions are being replaced or repeatedly resubmitted. This will not reveal intent with certainty, but it can show whether the launch is being dominated by highly optimized participants.

5. The failure pattern. Failed transactions are not just an emotional anecdote. They show how much demand is colliding with the contract and the available block space. But do not treat a failure percentage as a universal go/no-go threshold. It is context, not a magic number.

6. Your all-in cost at the bid level you can actually afford. Include the possibility of a failed attempt. If you would need several tries to have a realistic chance, calculate the cost of several tries. Do not compare the gas for one transaction with the mint price and call that the entry cost.

A useful decision is not “Can I afford the mint?” It is “Can I afford the mint, the likely gas, and the possibility that the transaction fails without delivering anything?” Those are different questions, and the second one is the only question that matters during a live auction.

The tools can help, but they do not remove the risk. Etherscan and other explorers can show pending activity with varying levels of completeness. Wallet interfaces can suggest fee settings. Specialized dashboards can estimate current competition. None of them can guarantee inclusion, and no dashboard can know whether the next block will contain a sudden wave of replacements from bots or private order flow.

There is also a dangerous psychological shift once a user has submitted the first transaction. After paying for a failed attempt, the next bid can feel like a way to recover the loss. It is not. The loss has already happened. The second transaction should be judged on its own expected cost, not on the emotional need to make the first one feel worthwhile.

When fees cross $50 for a single mint of an asset with a sub-$100 mint price, the asymmetry changes sharply. You are no longer buying an NFT with a small gas tax. You may be buying a gas fee with a small NFT attached. If the secondary-market premium disappears before your transaction confirms, the supposedly obvious discount can vanish.

The floor price does not rescue a bad transaction. A high pre-mint expectation is not the same as executable liquidity after launch. Even if the collection reaches a certain floor, that floor may represent a thin listing, not the price at which a large number of holders can sell. Gas-adjusted entry matters on the way in and on the way out.

Why gas wars can damage the holders projects say they want

A project that wants loyal holders should care about the composition of its first cohort, not merely about filling the supply.

A chaotic FCFS launch tends to reward people who can act quickly under financial pressure. That can produce a technically impressive mint and a weak social result. The wallets that wanted one token may never obtain one. The wallets that obtain many may have no reason to hold them. The collection then begins with a mismatch between the audience the marketing addressed and the audience the mechanism selected.

This mismatch can show up in several ways.

The first is distribution. If a small group of wallets captures a large share of the supply, the apparent number of holders may overstate the number of independent participants. The second is resale pressure. Large minters may sell into the first available liquidity, especially if their strategy was based on a short-lived price premium. The third is community sentiment. People who spent money on failed transactions often remember the launch as a loss even if they later buy on the secondary market.

The fourth is the floor-price narrative. A gas war can push early buyers toward a high effective cost basis. They may refuse to sell below that level, creating a stubborn layer of listings above the market. Or they may capitulate once the collection falls below their combined mint-and-gas cost, adding sudden supply. Neither outcome is a simple measure of conviction.

The project may also mistake technical survival for loyalty. A wallet that successfully navigated a difficult mint is easy to celebrate. It has a transaction hash, a token, and a place in the origin story. But the ability to win a block-space auction says little about whether the owner will participate in governance, attend community calls, use the art, or hold through a bear market.

The reverse is true as well. A wallet that failed to mint may remain one of the project’s strongest supporters. It may buy later, contribute to the community, or hold another collection asset for years. Excluding someone at mint does not prove they lacked commitment. It proves only that they lost an auction under a particular set of technical and financial conditions.

That is why the phrase “loyal holder” needs more discipline. Holder retention should be examined through later wallet behavior, not inferred entirely from mint-day survival. Useful signals include whether wallets continue to hold after the first major liquidity event, whether supply remains concentrated, whether large minters distribute tokens quickly, and whether repeat buyers return for subsequent drops. None is conclusive. Together, they tell a more honest story than a dramatic launch block.

The structural reality

Gas wars are not a bug in the NFT ecosystem. They are a predictable result of underpriced FCFS mechanics interacting with a mempool and a block-space market. Projects know this. Sophisticated participants plan around it. Validators and builders benefit from the additional fee activity. The casual collector who arrived because the community was excited carries much of the downside.

There is no protocol-level refund for a failed mint. There is no retroactive protection for a low bid that did not land. Ethereum did what it was designed to do: process valid transactions within constrained block space and prioritize the economics of inclusion. It does not know that one wallet is a veteran trader and another is a fan using the chain for the first time.

The answer is not to romanticize the filter. A difficult launch does not certify a strong holder base, and an easy launch does not guarantee weak hands. Better distribution methods can reduce the advantage of speed: allowlists with meaningful allocation limits, staged claims, longer windows, Dutch auctions, randomization, and post-mint claims all change the contest. Each has trade-offs, and each can be gamed. But they at least acknowledge that a mint is a market-design problem, not just a marketing moment.

The question worth asking is not whether gas wars build communities. It is whether the community you actually want — the one that holds through a second bear cycle, shows up for a governance vote, and does not dump into the first bid wall — can survive the entry tax the project has imposed.

The Otherside mint showed how extreme that tax can become, even for a project with substantial resources and technical reach. It also showed why mint-day distribution deserves more attention than a single headline floor price. A collection’s first holders are not selected by enthusiasm alone. They are selected by contract design, fee conditions, capital, infrastructure, and timing.

That does not make the outcome predetermined. It makes the starting point visible.

Filter accordingly.
