2025 was the year Bluefin became a multi-product ecosystem, serving as a unified platform for onchain markets and liquidity. Today also marks one year since the launch of BLUE, our native protocol token, which stands as a core pillar of the Bluefin ecosystem.

We are excited to share everything we achieved this year with the support of our community, partners, and team.

@zabimx Love to all builders 💙

Security has been a first-class citizen for both Bluefin and Suilend. Suilend was among the first lending protocols to build withdrawal rate limits directly into the protocol at inception, a standard we independently developed across Bluefin's own infrastructure. Their contracts have been audited by @osec_io, one of our long-standing audit partners, and formally verified by @Certora. That foundation is strong and complements our own posture.

We've spent years thinking through and refining our risk models, including liquidation engines, isolated markets, oracle integrity, and black swan event behavior, all of which we'll be leveraging to refine how risk is handled here. It will also draw on our real-time security partners, OtterSec and @AsymptoticTech, which we'll use for all enhancements and to include their verification attestations for contract upgrades.

The same engineering standards we hold at Bluefin will apply across both platforms: defense in depth from the contract layer through operations, institutional multisig custody, timelocked upgrades gated by audit-partner co-signers and a guardian pause, withdrawal limits sized to the real worst-case outflow, among the broader set of controls that make up our security standard.

Bluewater has acquired Suilend, and I'll be stepping in as CEO to help lead its next chapter.

Over the last 6+ years, nearly every waking hour of my life has gone into building Bluefin, and that’s not changing. When we started the company in 2020, we had a belief: financial markets would eventually live onchain, and over time, a new generation of financial infrastructure would emerge that was more open, transparent, and accessible.

Our ambition from day one was to build one of the leading trading venues. Today, that ambition only becomes stronger.

We've gone through multiple market cycles, rebuilt products from the ground up, and learned firsthand how much work still remains. While Bluefin has grown, I continue to view what we've accomplished so far as only the beginning of a much larger journey.

One of the reasons we’re so excited about this next chapter is the opportunity to accelerate what lending on Sui can become. We’re grateful for the trust that @MariusBarnett and @officialSUIG have placed in us, and we’re committed to building on the strong foundation the team has created. Over the coming months, we plan to bring new institutional capital, major RWA integrations, deeper liquidity, and a new generation of retail lending products to the ecosystem - with several institutional partnerships already in the pipeline. Our goal is simple: make Suilend the home for capital on Sui and help expand the role it plays within the broader onchain financial system.

We’ve known the Suilend team for years and have always respected the way they approached building. They focused on creating products that users could trust and took a deliberate approach to growth, security, and execution. Those qualities matter (a lot) when you're building infrastructure that people rely on with their money.

Suilend will continue operating as an independent platform with its own brand, community, and product direction. Bluefin will continue operating independently with the same mission that has guided us from the start. The objective is not to merge two products into one. The objective is to create stronger foundations for both platforms while allowing each team to remain focused on what they do best. I also want to be clear that stepping into this role does not come at the expense of Bluefin. Bluefin remains a core focus for me personally. Our goal of growing Bluefin into one of the leading trading venues in crypto remains unchanged.

Conviction is earned through experience. That’s why after 3 years of building on Sui, our belief in where this ecosystem is heading is stronger than ever.

We see an opportunity to contribute meaningfully to that future. Together, we will bring more users, more liquidity, and increasingly larger pools of institutional capital onto the network.

Much of the work is still ahead of us, but our approach remains the same as it has always been: stay focused, continue building, and never compromise on security.

As we move through this transition, user trust remains at the center of every decision we make.

I'm incredibly excited about what lies ahead for both Bluefin and Suilend, and even more excited about what we can help build on Sui over the coming years. Thank you all for your trust and support.

The work continues.

Bluefin’s formal role as a distribution partner for AlphaLend has concluded effective May 17, 2026.

Over the coming weeks, AlphaLend will continue to remain accessible through the Bluefin interface before being gradually phased out from the platform.

Since the start of the partnership, the Bluefin community contributed more than 40% of AlphaLend’s TVL, helping scale the protocol into one of the leading lending markets on Sui. We’re grateful to the AlphaLend team and community for their partnership and collaboration throughout that growth.

As part of this transition, deposits associated with AlphaLend will no longer be reflected under Bluefin platform metrics.

This transition does not impact user funds, positions, or access to the protocol during the migration period.

Bluefin remains focused on building the leading onchain trading and capital markets platform on Sui, while continuing to expand access to the highest quality products and opportunities for our users.

Silver (XAGm) by @matrixdock is now live for trading on Bluefin Spot!

[Matrixdock @matrixdock]

BREAKING: @Matrixdock Silver $XAGm is now live on @SuiNetwork, the first silver asset natively issued on the network.

Unlike gold, silver's higher volatility and industrial demand make it built for active use: trading, lending, collateralization. And as on-chain silver perps markets grow, institutional spot trade becomes foundational infrastructure — not optional.

XAGm is physically backed by LBMA Good Delivery bars, independently audited, and redeemable for physical silver. One of the few products globally to meet this standard on-chain.

Sui has allocated a portion of its treasury into XAGm, signaling conviction in tokenized silver as reserve-grade infrastructure.

From issuance to execution. $XAGm is live.
