Blur:
the trader's marketplace, built on zero fees and a listing loophole that cost one user $240K.
We're opening a new series, NFT Marketplaces, with Blur, the Ethereum-based marketplace and aggregator that overtook OpenSea in 2023 by charging professional traders nothing. Real, disclosed genuinely distinctive positioning: bulk sweeping, collection-level bids, and real-time floor analytics built specifically for high-frequency traders rather than casual collectors, backed by Paradigm and founded by publicly-identified co-founders Tieshun Roquerre ("Pacman") and Anthony Liu ("Galaga"). Real, disclosed headline advantage: a genuine 0% marketplace fee, undercutting OpenSea's 0.5-2.5%. What we want to correct directly: at least one review we found claims Blur has "operated without major security incidents since launch." Our own research found a real, confirmed platform-level exploit in June 2023, where an attacker manipulated Blur's own royalty and listing settings to engineer fraudulent private sales, draining roughly $240,000 in NFTs from a single victim, plus a sustained pattern of serious, repeated phishing campaigns specifically targeting Blur users in December 2023. Real, disclosed unresolved dispute worth naming directly: NFT data aggregator CryptoSlam reportedly revoked $577 million in Blur volume over wash-trading concerns, while a separate independent Dune analysis concluded the volume was legitimate. And real, disclosed governance gap: the BLUR token, down 99.6% from its February 2023 peak, carries no fee accrual, and a proposal to route protocol revenue to holders still hasn't passed; and landed on a score the marketing page won't show you.
Our take, up front: Blur is an Ethereum-based NFT marketplace and aggregator, founded in October 2022 by Tieshun Roquerre ("Pacman," an MIT graduate and Peter Thiel Fellow) and Anthony Liu ("Galaga"), backed by Paradigm, and built specifically for high-volume professional traders rather than casual collectors. Real, disclosed genuinely distinctive positioning: bulk sweeping, collection-level bids, real-time floor and depth analytics, and aggregated listings pulled from multiple marketplaces including OpenSea and Rarible, all built around trader workflows rather than browsing aesthetics. Real, disclosed headline advantage: a genuine 0% marketplace fee, the most competitive fee structure among major NFT platforms, against OpenSea's 0.5-2.5%. What we want to correct directly: several reviews we found describe Blur as having operated "without major security incidents since launch." Our own research found this doesn't hold up. In June 2023, an attacker known as Pink Drainer exploited a genuine loophole in Blur's own listing and royalty system, engineering fraudulent private sales that let them buy six Bored Ape Yacht Club NFTs, 40 Beanz, and three Elementals for one wei each, roughly $239,676 in real value, from a single victim; Blur reportedly did not immediately respond to a request for comment. Separately, December 2023 brought at least two distinct, serious phishing campaigns against Blur users within under two weeks, one netting 185 CryptoPhunks and 7,304 Meebits, a second netting Mutant Ape Yacht Club and Moonbirds pieces, both tracked and disclosed by security firm PeckShield. Real, disclosed unresolved dispute worth naming directly: NFT data aggregator CryptoSlam reportedly revoked $577 million in Blur trading volume over wash-trading concerns tied to the BLUR airdrop, while a separate, independent Dune analysis by data scientist Hildebert Moulié concluded the underlying volume was legitimate; we're not picking a side neither of our sources definitively settles. And a real, disclosed governance gap: the BLUR token, down 99.6% from its February 2023 peak of $5.02 to about $0.02, carries no fee accrual, and a proposal to route protocol revenue to holders still hasn't passed as of our research. We weighted all of it below.
Real, disclosed, confirmed platform-level exploit: in June 2023, an attacker manipulated Blur's own listing and royalty settings to engineer fraudulent private sales, draining roughly $240,000 in NFTs from a single victim. Real, disclosed, sustained pattern of serious phishing campaigns specifically targeting Blur users: at least two distinct incidents in December 2023 alone, tracked by security firm PeckShield, netting thousands of NFTs. Real, disclosed lack of prompt public response to at least one major incident. What tempers this less severely: no confirmed direct hack of user funds held in marketplace escrow itself, and the exploits found were listing-mechanism and social-engineering based rather than a core smart-contract fund drain.
Pros
- No confirmed direct hack of user funds held in marketplace escrow
- The June 2023 listing loophole appears to have been a one-time, disclosed exploit pattern rather than a recurring one
Cons
- Jun 2023: a confirmed $240K exploit of Blur's own listing/royalty mechanism
- Dec 2023: at least two separate, serious phishing campaigns within under two weeks
- At least one "no major security incidents" marketing claim doesn't hold up against our research
Real, disclosed genuinely dominant historical volume, having surpassed OpenSea in 2023, and still described as the dominant marketplace by trader volume per active user within its professional-trader niche as of 2026, per a detailed source. Real, disclosed $1.4B+ in aggregated listings surfaced from multiple marketplaces. What tempers this significantly: a real, disclosed, unresolved wash-trading dispute, NFT data aggregator CryptoSlam reportedly revoked $577 million in Blur volume over manipulation concerns, while a separate independent Dune analysis concluded the volume was legitimate. Real, disclosed dramatic 2025 shift: OpenSea's broader market share jumped from 25% to 71.5% overnight following its own token announcement, meaning Blur's relative dominance has narrowed substantially outside its specific niche.
Pros
- Still the dominant marketplace by trader volume per active user in its niche, per a detailed source
- $1.4B+ in aggregated listings surfaced from across multiple marketplaces
Cons
- A real, disclosed, unresolved dispute over wash-trading inflation of reported volume
- OpenSea's broader market share surged from 25% to 71.5% overnight in 2025, narrowing Blur's relative position
Real, disclosed named founders, Tieshun Roquerre ("Pacman") and Anthony Liu ("Galaga"), both publicly identified after initially operating pseudonymously. Real, disclosed functioning BLUR governance token letting holders vote on protocol decisions. What tempers this significantly: real, disclosed lack of value accrual, BLUR carries no fee-sharing mechanism for holders, and a proposal to route protocol revenue to token holders still hasn't passed, meaning governance rights exist without an accompanying economic claim on the platform's own revenue.
Pros
- Named, publicly-identified founders; backed by Paradigm
- Functioning BLUR governance token with real voting rights
Cons
- No fee accrual or revenue-sharing mechanism for BLUR holders
- A proposal to route protocol revenue to holders still hasn't passed
Real, disclosed aggregation across multiple marketplaces, including OpenSea and Rarible, surfacing broad Ethereum-native collection coverage in one place. What tempers this: real, disclosed Ethereum-only scope as of 2026, no Solana, Polygon, or other multi-chain support, a genuinely narrower footprint than multi-chain competitors.
Pros
- Aggregates listings across multiple marketplaces for broad Ethereum-native coverage
Cons
- Ethereum-only; no Solana, Polygon, or other chain support as of 2026
Real, disclosed genuinely distinctive trader-focused design: bulk/sweep buying, real-time floor and depth analytics, collection-level bidding, and workflow bundling that collapses listing, cancelling, and sweeping into fewer steps, a deliberately different philosophy from collector-oriented browsing.
Pros
- Genuinely distinctive bulk sweeping, collection bids, and real-time depth analytics
- Workflow bundling reduces the steps needed for high-frequency trading
Cons
- Deliberately less suited to casual collectors who prefer simple browsing
Real, disclosed headline 0% marketplace fee, the most competitive structure among major NFT platforms, a genuine, substantial cost advantage for high-volume traders versus OpenSea's 0.5-2.5%. What tempers this: real, disclosed controversial royalty model, only a 0.5% minimum enforced royalty with the remainder optional, a design directly, disclosedly central to the industry-wide 2023 "royalty wars" that reduced creator royalty income across the NFT ecosystem broadly.
Pros
- Genuine 0% marketplace fee, the most competitive among major platforms
Cons
- Only a 0.5% minimum enforced royalty; the rest is optional
- Directly, disclosedly central to the 2023 industry-wide decline in creator royalty income
Real, disclosed Blend lending protocol: peer-to-peer, NFT-collateralized loans with no fixed expiry and refinancing mechanics, a genuinely distinctive integration of trading and lending in one ecosystem. What tempers this: a real, disclosed 2024 stress event where falling floor prices triggered waves of liquidations on leveraged blue-chip positions, demonstrating real, disclosed systemic risk in the lending product specifically.
Pros
- Blend's integrated NFT-collateralized lending is a genuinely distinctive feature
Cons
- 2024: falling floor prices triggered real, disclosed liquidation waves on leveraged positions
Access only through Blur's official site, and double-check royalty and listing settings before signing.
Given the real, disclosed June 2023 listing-loophole exploit and the sustained pattern of phishing campaigns specifically targeting Blur users, verify every listing and signature request directly in your wallet before approving, and never assume a low listing price is a mistake you can safely exploit yourself.
A genuinely useful tool for traders, with a security story that's more complicated than "no major incidents."
We want to give Blur real credit for what it actually built: a genuinely distinctive, trader-first product that legitimately out-competed OpenSea on speed and cost for the specific users it targets, and a 0% fee structure that's a real, substantial saving for anyone trading at volume. That's not nothing, and it's why this doesn't score at the bottom of what we expect this new series to cover. But we can't let a marketing claim of "no major security incidents since launch" stand unchallenged when our own research found a confirmed, real $240,000 exploit of the platform's own listing mechanism, and a distinct, sustained wave of serious phishing campaigns in the same year. Layer on a genuinely unresolved wash-trading dispute that neither side has definitively settled, and a governance token that's lost 99.6% of its value while never gaining the ability to actually capture protocol revenue, and we think a fair score has to sit closer to the middle than the marketing suggests. Blur solved a real problem for traders. It hasn't yet fully solved the trust problem that comes with being the venue where the money moves fastest.
The scorecard above is deliberately general. Whether Blur is right for you depends heavily on which of these you already are.
The high-frequency Ethereum NFT trader who wants zero fees, bulk sweeping, and collection-level bidding
This is exactly where Blur's genuinely distinctive, trader-first design delivers real, demonstrated value.
The user who verifies every listing and signature request directly in their wallet before approving
Given the real, disclosed June 2023 listing-loophole exploit and repeated phishing campaigns, this habit genuinely matters here.
The Blend user who understands leveraged NFT positions can face real liquidation waves when floor prices fall
Given the real, disclosed 2024 stress event, sizing any NFT-collateralized loan conservatively genuinely matters here.
Casual collectors, creators who depend on royalty income, or traders on chains other than Ethereum
OpenSea and Magic Eden, likely to be reviewed later in this series, are built more directly around those specific needs.
The scorecard covers the headline judgment calls. These four tables cover the specifics we didn't want to bury in prose; the June 2023 listing exploit explained step by step, the December 2023 phishing wave compared, Blur's fees weighed directly against OpenSea, and the BLUR/BLAST parallel named precisely.
The June 2023 listing exploit, step by step
| Step | What happened |
|---|---|
| 1. The setup | An attacker known as Pink Drainer manipulated the royalty settings on high-value NFTs to bypass Blur's public-accessibility listing requirement |
| 2. The rule | A rule was set canceling any transaction unless the attacker's own address was the buyer, effectively making the listing private despite Blur not officially offering private listings |
| 3. The bait | The victim was lured via a promised free NFT mint or airdrop, then tricked into approving a transaction on a phony website |
| 4. The listing | Six Bored Ape Yacht Club NFTs, 40 Beanz, and three Elementals were listed at one wei each, effectively zero, without the owner's knowledge |
| 5. The result | Only the attacker's own wallet could fulfill the listings; roughly $239,676 in real value was extracted |
This is a real, confirmed exploit of Blur's own listing and royalty mechanism, not pure social engineering; the victim's NFTs were made purchasable by only one wallet, defeating the platform's own core design principle that listings are open to anyone.
The December 2023 phishing wave, compared
| Date | What was stolen |
|---|---|
| ~Dec 19, 2023 | 185 CryptoPhunks and 7,304 Meebits, tracked to "Fake_Phishing187019" by PeckShield |
| ~Dec 19, 2023 (separate) | 85 0xLBOTS and 152 CypherpunkZero, via a distinct ERC2771 + multicall attack pattern |
| ~Dec 28, 2023 | Mutant Ape Yacht Club #184 and Moonbirds #7931/#8749, same "Fake_Phishing187019" actor |
At least two distinct attack patterns and one repeat actor, active within roughly a two-week window; PeckShield's own headline for this period was "Blur Hit With Another NFT Phishing Attack In Less Than Two Weeks."
Fees and royalties: Blur vs. OpenSea
| Blur | OpenSea | |
|---|---|---|
| Marketplace fee | 0% | 0.5% |
| Minimum enforced royalty | 0.5% (higher defaults possible per collection, e.g. up to 8% on BAYC) | Optional, following Blur's lead after 2023's "royalty wars" |
| Primary user base | Professional, high-frequency traders | Broader, mass-market collectors |
Blur's optional-royalty model was disclosedly central to forcing OpenSea's own royalty policy to shift in 2023, a real, industry-wide second-order effect on creator income that extends well beyond Blur's own platform.
BLUR and BLAST: the same founder, the same pattern
| BLUR token | BLAST (Blur founder's L2) | |
|---|---|---|
| Peak | $5.02 (Feb 2023) | $2.7B TVL at peak |
| Decline | ~99.6% (to ~$0.02 by 2026) | ~97% (to ~$65M TVL) |
| Cross-link | Blur traders received BLAST airdrops, tying the two ecosystems' incentives together | Same |
Both products, built by the same founding team, followed a genuinely similar arc: a massive, incentive-driven launch followed by a steep decline; a detailed source describes this pattern directly rather than treating either decline as an isolated event.
We don't just want to hand you our number; we want to show you how it sits next to what other review desks and comparison sites have published. We're flagging directly that at least one source we found claims Blur "operated without major security incidents since launch," a claim our own research directly contradicts.
Our score lands meaningfully below the aggregated industry average; most general reviews we found focus on Blur's genuine fee advantage and trader-first UX without weighting the confirmed June 2023 exploit, the repeated December 2023 phishing waves, or the token's lack of value accrual as heavily as our methodology does.
| Source | Score | Type |

Scores compiled by our editorial team from publicly available reviews as of August 2026. "Editorial estimate" means the outlet didn't publish a single numeric score, so we converted their published verdict and sentiment into a comparable 100-point figure. Verify current figures directly with each source before citing them elsewhere.
Yes, in a real, disclosed sense. In June 2023, an attacker exploited a genuine loophole in Blur's own listing and royalty system to engineer fraudulent private sales, draining roughly $240,000 in NFTs from a single victim. Separately, December 2023 brought at least two distinct, serious phishing campaigns against Blur users within under two weeks.
This is genuinely disputed. NFT data aggregator CryptoSlam reportedly revoked $577 million in Blur volume over wash-trading concerns tied to the BLUR airdrop, while a separate, independent Dune analysis by data scientist Hildebert Moulié concluded the volume was legitimate. We haven't found a source that definitively settles this either way.
Blur charges a 0% marketplace fee, the most competitive structure among major NFT platforms. You still pay Ethereum gas and a minimum 0.5% enforced creator royalty, though the remainder beyond that minimum is optional.
Blend is Blur's NFT-collateralized, peer-to-peer lending protocol with no fixed expiry and refinancing mechanics. In 2024, falling floor prices triggered waves of liquidations on leveraged blue-chip positions, a real, disclosed demonstration of how quickly borrowing against illiquid NFT collateral can unwind.
BLUR launched at $5.02 in February 2023 and has fallen roughly 99.6% to about $0.02 as of our research. The token is used for governance voting but has no fee accrual, and a proposal to route protocol revenue to holders still hasn't passed.
Tieshun Roquerre, known as "Pacman," an MIT graduate and Peter Thiel Fellow, and Anthony Liu, known as "Galaga," founded Blur in October 2022. Both operated pseudonymously at first before being publicly identified. Blur is backed by Paradigm.
No. As of our research, Blur remains Ethereum-only, with no Solana, Polygon, or other multi-chain support, unlike broader competitors such as OpenSea or Magic Eden.
Blast is a separate Ethereum L2 launched by Blur's founder. It hit $2.7 billion in TVL at its peak before collapsing 97% to roughly $65 million, and Blur traders received BLAST token airdrops, tying the two ecosystems' incentives together.
