The current spam problem on Ethereum is real, but it is also easy to describe badly. A lot of people talk about it as if one update broke the network and invited scammers in. That is too simple. What actually happened is that cheaper blockspace and lower-cost execution made nuisance behavior easier to scale. Once it became cheap enough to spray wallets with junk, poison transaction history, and flood users with worthless token transfers, attackers did what attackers always do: they industrialized it.

The good news is that this is not an unsolved mystery. The bad news is that it is not one bug with one patch either. Ethereum and other chains are dealing with three connected problems at once: spam tokens, classic dusting behavior, and address poisoning. They overlap, but they are not identical. If the ecosystem wants to reduce them properly, it has to fix the economics, the wallet interface, and the way users confirm recipients.

What the Problem Actually Is

Spam tokens are unsolicited assets pushed into wallets to lure users toward malicious sites, fake claims, or bad approvals. Address poisoning is a different scam. The attacker sends a worthless or zero-value transfer from an address that visually resembles one the victim already uses, hoping the victim later copies the poisoned address from transaction history. That is not a protocol hack. It is a user-interface trap.

Dust attacks are related, but they are not exactly the same thing. Classic dusting is more naturally associated with UTXO-style chains, where tiny outputs can be used to track wallet behavior and cluster addresses. On Ethereum and similar account-based networks, what most users call “dusting” is often really spam or address poisoning.

That distinction matters, because the fixes are different. You cannot solve a history-copying scam with the same tool you would use to prevent wallet clustering on Bitcoin.

Why the Problem Got Worse When Transactions Got Cheaper

Ethereum’s major scaling upgrades were meant to make the network more usable, and in that sense they worked. The Dencun upgrade sharply reduced rollup data costs, and later roadmap work such as Fusaka continued pushing cheaper data availability for layer-2 systems. Official Ethereum documentation is clear that these upgrades were aimed mostly at lowering L2 costs, not directly rewriting L1 gas economics. Even so, once enough parts of the Ethereum stack become cheap to use, abuse becomes cheap too.

That is the part many people feel in practice. If it costs almost nothing to broadcast junk at scale, then a scammer does not need a high conversion rate. They only need a small number of distracted users to copy the wrong address or click the wrong token. Cheap blockspace is wonderful for honest users, but it also reduces the cost of nuisance behavior unless the rest of the stack becomes much better at filtering it.

So the real question is not whether Ethereum should become expensive again just to inconvenience scammers. It is whether the ecosystem can keep fees low for useful activity while making spam costly, invisible, or both.

What Ethereum and Other Chains Should Fix at the Protocol Level

The first hard truth is that public blockchains cannot fully stop strangers from sending you assets or transfers. That openness is part of the design. So the realistic protocol goal is not “ban spam.” It is “price permanent damage properly and stop subsidizing junk.”

The cleanest long-term direction is stronger repricing of state growth and long-lived garbage. Ethereum’s own roadmap already points toward this logic through state scaling, state expiry, and history expiry. If the network makes it more expensive to leave useless state behind forever, then mass token spraying becomes less attractive. Chains do not need to kill composability to do this. They need to stop treating permanent storage like a free landfill.

A second protocol-level improvement is better economic separation between high-value activity and junk creation. If a token issuer wants to push unsolicited assets into millions of wallets, that should not be as cheap as a normal user making a standard transfer. The exact mechanism can vary by chain, but the principle is simple: permanent wallet clutter should cost more than ordinary use.

A third improvement is standards work. Token standards could move toward clearer metadata rules, issuer attestations, or opt-in display models for unknown assets. That would not stop someone from deploying junk, but it would make it harder for junk to masquerade as something worthy of attention.

Wallets and Explorers Are Where the Biggest Immediate Fixes Live

The fastest improvements do not need a hard fork. They need better wallet defaults.

The first fix is obvious: unknown tokens and unsolicited collectibles should be hidden by default. Not deleted, not censored, not made impossible to inspect, just quarantined. This is already the direction some wallets are taking. Phantom now flags and filters tokens that appear misleading, unsafe, or spammy, and that is closer to the right model than treating every inbound token as worthy of equal screen space.

The second fix is more important for Ethereum specifically: transaction history should stop acting like a trusted address book. Wallets and explorers should visually separate user-saved contacts from unsolicited senders, zero-value transfers, and newly seen addresses. They should make it much harder to copy a poisoned address by accident and much easier to understand whether an address came from a known contact, a verified domain, or a random inbound transfer.

The third fix is defensive display design. A wallet should show more than the first and last few characters when funds are leaving. It should lean on saved contacts, ENS-style naming where appropriate, and explicit recipient confirmation. Ledger Wallet already hides 0-value transactions as a defense against address poisoning, and more wallets should follow that lead.

Block explorers also need to stop presenting poisoned history like normal activity. A zero-value transfer from an unknown token contract should never look as legitimate as a real payment to a saved recipient.

Exchanges, Custodians, and Stablecoin Issuers Can Help Too

A lot of damage happens after a bad address is copied, not when the spam first appears. That means exchanges and custodians can cut risk materially by making withdrawal destinations more deliberate.

The most effective tools already exist. Coinbase’s allowlisting system limits withdrawals to saved addresses. More platforms should treat that as a default posture, not an optional advanced feature. If users are withdrawing to approved destinations only, poisoned transaction history becomes much less dangerous.

Institutional wallets should go even further. They should require named destination books, two-person review for new addresses, and a cooling-off period before a newly added withdrawal address can receive large transfers. None of that is glamorous, but it works.

What Users Can Do Right Now

The user-side fixes are boring, which is exactly why they work.

Do not copy addresses from transaction history. Use saved contacts or verified destination books. Do not touch unsolicited tokens just because they appeared in the wallet. Do not assume a wallet is compromised simply because junk arrived. In many cases, nothing was stolen at all. The attacker is waiting for the victim to make the next mistake.

For larger transfers, send a small test amount first. Use hardware confirmation where possible. Verify more than the first and last characters of an address. Better still, stop relying on raw address fragments as the main identity system in the first place.

Why This Is Not Just an Ethereum Problem

Ethereum gets the most attention because its ecosystem is large, liquid, and full of visible wallets and stablecoin flows. But the problem is broader than Ethereum. Any low-fee chain can attract spam once attackers decide the economics work. In fact, lower-fee chains may be even more vulnerable if their wallet layer is immature or their explorer design is sloppy.

That is why the right lesson is not “Ethereum should raise fees until spam goes away.” The right lesson is that every chain needs a serious anti-spam stack: sane pricing for persistent clutter, wallet quarantine for unknown assets, recipient verification, better address books, and much stronger visual separation between trusted activity and random inbound noise.

Conclusion

Ethereum and other chains are not going to eliminate spam by pretending openness can be rolled back. Public networks will always let strangers send things to public addresses. The real answer is to make that behavior much less useful.

That means pricing persistent junk more honestly at the protocol layer, hiding unknown assets by default at the wallet layer, redesigning transaction history so it cannot double as a phishing tool, and pushing users toward verified destination books instead of copy-paste habits. If the ecosystem does those four things well, spam tokens, dust attacks, and address poisoning will not disappear entirely. They will just stop working often enough to be worth the attacker’s time.
