The NFT marketplace landscape has entered a new phase of strategic innovation and competition, with Blur and OpenSea at the center of a high-stakes technological and economic showdown. What began as a battle over creator royalties has evolved into a sophisticated game of protocol-level maneuvering—one that’s reshaping how NFTs are traded, who benefits, and where the future of digital ownership is headed.
This article dives deep into the two pivotal rounds of this rivalry, unpacking how Blur bypassed OpenSea’s blacklist, the implications for creators and traders, and what this means for the broader NFT ecosystem in 2025 and beyond.
The Rise of Two NFT Giants
At the heart of the current NFT market are two dominant platforms: OpenSea and Blur. Together, they account for the vast majority of NFT trading volume across Ethereum and other blockchains.
- OpenSea, the long-standing leader, built its reputation on accessibility, broad collection support, and early adoption.
- Blur, launched in October 2022, quickly gained traction among professional traders by offering advanced tools, zero platform fees, and lucrative token incentives.

While OpenSea focused on mainstream users and creators, Blur targeted speed, efficiency, and volume—ultimately challenging OpenSea’s dominance. By late 2022, Blur’s daily trading volume briefly surpassed OpenSea’s, signaling a shift in market dynamics.
But OpenSea wasn’t going to surrender control without a fight.
Round One: OpenSea’s Defense – The Royalty Blacklist
In November 2022, OpenSea introduced a controversial policy designed to protect creator royalties:
NFT projects that wanted OpenSea to enforce royalties had to block marketplaces that didn't respect them, including Blur.
This meant:
- Any new NFT collection choosing royalty enforcement had to blacklist Blur in their smart contracts.
- As a result, those NFTs could no longer be listed or traded on Blur.
- Projects like Yuga Labs’ Sewer Pass complied, aligning with OpenSea and cutting off Blur access.
This move was widely seen as an attempt to protect OpenSea’s market share under the banner of supporting creators. After all, data showed that 92% of trades on OpenSea honored royalties, compared to just 19% across other platforms.
Blur responded by pledging to enforce royalties on new collections and formally requested removal from the blacklist. However, OpenSea held firm: their policy required universal royalty enforcement, not just for new projects.
Result: Round One – OpenSea wins.
Blur remained blacklisted, unable to list many high-profile new mints. Creators were forced into a difficult choice:
- Choose OpenSea → lose exposure to Blur’s high-volume traders.
- Choose Blur → risk losing royalty income.
This tension placed immense pressure on creators navigating the fragmented marketplace landscape.
Round Two: Blur’s Countermove – Exploiting Seaport Protocol
Enter Seaport, OpenSea’s own open-source, permissionless NFT trading protocol.
Launched to decentralize NFT trading and encourage innovation, Seaport allows any developer to build marketplaces on top of it—without needing approval from OpenSea. Over 20 teams, including Blur, have adopted Seaport to power their trading infrastructure.
Here’s where Blur made its masterstroke.
Instead of trying to get un-blacklisted, Blur built a new trading system using Seaport directly. Because:
- The Seaport protocol itself isn’t blacklisted, even if Blur is.
- NFTs that “block Blur” only restrict direct integrations—not indirect ones via shared protocols.
💡 This workaround allows Blur to now trade previously restricted NFTs through Seaport-based execution—while still enforcing royalties via compliant contracts.
In essence:
- Old System: Handles NFTs that never blacklisted Blur.
- New System: Routes trades through Seaport for blacklisted collections.
- User Experience: Fully seamless—Blur automatically selects the correct path.
As a result:
- All ERC721 NFTs can now be traded on Blur.
- Creators receive full royalties on both OpenSea and Blur.
- Traders enjoy lower friction with zero platform fees.

Result: Round Two – Blur wins.
Why OpenSea Can’t Stop This
You might ask: Can OpenSea block Blur’s new system?
Technically—no.
Because both platforms run on Seaport, any attempt by OpenSea to block Blur would also disrupt its own operations. It’s a classic case of self-undermining defense: the very openness that made Seaport powerful also made it exploitable.
Think of it like the Maginot Line—France’s elaborate WWII defense system. It was strong—but when Germany simply went around it through Belgium, the entire strategy collapsed.
Similarly:
- OpenSea built a “Maginot Line” via blacklists.
- Blur didn’t break through—it went around using Seaport.
- Now, the defensive wall is obsolete.
Impact Across the Ecosystem
For Blur: Regaining Momentum
Blur’s strategic pivot has re-established its position as a major player:
- Already capturing 10% of trading volume from previously restricted NFTs—without public announcement.
- Positioned for growth ahead of the anticipated $BLUR token airdrop, which could drive further user acquisition.
- Reinforced credibility among traders seeking maximum liquidity and minimal fees.
For Creators: Full Royalty Recovery
This is perhaps the biggest win for creators:
- They can now enforce royalties on both platforms.
- New projects: Simply blacklist non-compliant markets in their contract.
- Existing projects: Can upgrade or deploy new contracts to regain royalty control.
No longer forced to choose between visibility and revenue, creators gain flexibility and financial security.
For Traders: Unrestricted Access
Traders benefit from:
- Ability to trade all ERC721 NFTs on a zero-fee platform.
- Improved arbitrage opportunities across markets.
- Note: Currently, blacklisted NFTs can be listed on Blur’s frontend but cannot accept bids—a limitation that may evolve.
For OpenSea: Mixed Outcomes
Despite losing this round strategically, OpenSea isn’t without gains:
- Seaport adoption strengthens its influence as a protocol provider.
- Its push for royalty protection raised industry standards.
- More creators earning consistent royalties may fuel long-term Web3 content creation—benefiting all platforms.
However, the episode highlights a critical lesson: centralized policies clash with decentralized realities.
Frequently Asked Questions (FAQ)
Q: How did Blur bypass OpenSea’s blacklist?
A: Blur used OpenSea’s own open-source Seaport protocol, which isn’t subject to marketplace blacklists. By routing trades through Seaport, Blur can list NFTs even if they explicitly block the Blur platform.
Q: Can creators still earn royalties on Blur?
A: Yes. Thanks to Seaport integration and compliant smart contracts, creators receive full royalties on eligible NFTs traded via Blur’s new system.
Q: Is OpenSea losing relevance?
A: Not yet. OpenSea remains the most widely used NFT marketplace, especially among casual users and new collectors. However, its policy limitations have opened doors for technically agile competitors like Blur.
Q: Does this affect all blockchains?
A: Currently, this primarily impacts Ethereum-based ERC721 NFTs. Other chains may see similar developments if they adopt comparable protocols.
Q: Will other platforms copy Blur’s strategy?
A: Likely. The success of this approach could inspire other marketplaces to build similar workarounds using open protocols—accelerating decentralization across NFT trading layers.
Q: What’s next for NFT marketplace competition?
A: Expect increased innovation in protocol-layer solutions, royalty enforcement mechanisms, and cross-platform interoperability. The focus will shift from platform lock-in to seamless, user-first experiences.
