Top Sui DEX Bluefin launches Bluefin7K aggregator for better rates and liquidity

Bluefin is doing more than leading the charts, as it sets the pace. As the number one decentralised exchange on the Sui blockchain, Bluefin is taking a big leap forward. On June 3, 2025, the platform announced the official launch of Bluefin7K, a Sui-native aggregator built to secure the best possible rates and liquidity for users.

This is not just a feature but a turning point.

What Is Bluefin7K?

Bluefin7K is an advanced trade aggregator. It works by routing user trades through multiple decentralised exchanges within the Sui ecosystem. The goal is to provide users with the best price and the deepest available liquidity.

In real-time, Bluefin7K searches across DEXes to find the most favourable match for each trade. That means less slippage, better fills, and more efficiency with every transaction.

Bluefin7K is powered by the aggregator tech stack from 7K Smart Trading. The two teams have now partnered to bring this capability under the Bluefin umbrella. However, both companies will continue to operate independently.

It’s a strategic collaboration because Bluefin gets best-in-class infrastructure while 7K gains a broader user base. Traders are not left behind as well. They get a smoother, smarter, and more optimised trading experience.

Why Aggregators Matter Right Now

The DeFi space is growing fast, and new DEXes are popping up every month. Liquidity is often fragmented across platforms.

For traders, this means missed opportunities.

Without an aggregator, users have to manually compare rates on different platforms. This is time-consuming and risky, as prices can shift within seconds. Aggregators solve this. They automate the process, identify the best trade routes, and help users save money and time on every single trade.

With Bluefin7K, Sui traders now have a native solution designed specifically for their ecosystem. No more relying on Ethereum or cross-chain tools. This is built for Sui from the ground up.

The Bluefin and 7K Smart Trading Partnership

Behind the scenes, the tech that powers Bluefin7K comes from 7K Smart Trading. 7K is known for building robust aggregator stacks that can plug into trading protocols across blockchains. Its infrastructure is fast, precise, and flexible.

By partnering with 7K, Bluefin gains access to a mature aggregation engine. It didn’t have to build one from scratch. Instead, it integrated the technology and rebranded it under the Bluefin name.

This move lets Bluefin stay focused on its core strengths: trading tools, derivatives, and exchange design. Meanwhile, the aggregation engine takes care of routing and optimisation.

Even with the partnership, both companies remain independent. There’s no merge here, just collaboration. Bluefin continues to manage its DEX and roadmap. 7K continues to serve other partners, too.

This clean separation ensures both platforms stay lean, nimble, and focused.

A Big Month for Bluefin

The launch of Bluefin7K is part of a larger wave of updates in the Bluefin ecosystem. Just days earlier, on May 29, Bluefin’s native token, BLUE, got listed on the Backpack exchange. It marked a key moment in Bluefin’s token journey.

BLUE is not just a governance token. It comes with real utility. Holders can get fee discounts, earn staking rewards, and participate in platform incentives. This gives the token more value than just speculation. It’s tied to activity and engagement within the platform.

Before that, on May 27, Bluefin announced a partnership with Asymptotic Technologies. The goal was to formally verify its core math library — the code that handles trade calculations, price discovery, and balances.

This kind of formal verification is rare in DeFi. It’s a highly rigorous process that ensures the system’s math is not just functional but provably correct. 

Why does this matter? Because if the math is wrong, the trades break, prices slip, funds get misallocated, and security gaps open.

By working with Asymptotic, Bluefin is tightening its foundation, making sure the protocol is built on solid ground.

Bluefin Pro Set the Stage

Back in March 2025, Bluefin launched another major initiative: Bluefin Pro. This was a high-performance derivatives exchange aimed at both retail and institutional traders. Bluefin Pro came with features like cross-margining, regulated and permissionless versions, and lightning-fast execution.

It was a move to bring serious trading infrastructure to the Sui blockchain. Now, with Bluefin7K, Bluefin is addressing the other half of the market being spot trading and liquidity optimisation.

Together, these tools create a comprehensive suite for Sui-based trading. Bluefin isn’t just a DEX anymore. It’s becoming a platform ecosystem.

What Bluefin7K Means for Sui Traders

This aggregator unlocks several immediate benefits for users on Sui:

1. Better Trade Execution
Bluefin7K will always route your trade to the best available price. No manual comparison needed.

2. Lower Slippage
Because trades are pulled from deeper liquidity sources, users lose less value to slippage on larger orders.

3. Real-Time Efficiency
The system makes decisions in real-time, based on market conditions. This reduces the risk of sudden price changes ruining trade value.

4. Seamless Integration
All of this happens within the Bluefin interface. Users don’t have to leave the app or connect to multiple protocols.

For new users, this simplicity is game-changing. For advanced users, it saves time and optimises strategies.

The Bigger Picture for Bluefin

Bluefin has been on a steady rise since early 2024. It quickly became the top DEX by trading volume on Sui and has kept that lead ever since. What sets it apart is a focus on performance. Many DEXes chase hype, while Bluefin builds tools.

It didn’t rush its token listing. It formalised its math, launched Bluefin Pro, and now it’s bringing in smart aggregation via Bluefin7K. Each move has been intentional, and each one makes Bluefin more valuable. This is not just a trading platform but a core piece of the Sui DeFi stack.

With Bluefin7K live, users can expect more integrations and optimisations. Bluefin is expected to expand Bluefin7K’s routing coverage to include new DEXes as they emerge in the Sui ecosystem.

What’s Next?

Bluefin7K is more than an aggregator. It’s a reflection of where Bluefin and Sui DeFi are going. Better tools, smarter routing, and more reliability. As the Sui ecosystem grows, competition between DEXes will heat up. Liquidity also gets spread thin, and user expectations rise.

With Bluefin7K, Bluefin is making sure it stays ahead of the curve. It’s not just trying to be the biggest but trying to be the smartest. For traders on Sui, that could make all the difference.
