Bluefin Is a Decentralized Exchange on Sui

Bluefin is a decentralized exchange for spot, derivatives, and other onchain markets. Since 2023 it has been built on Sui. Its official site is bluefin.io, and its official account on X is @bluefinapp.

The homepage headline is “Global Markets, Rebuilt Onchain.” The page describes the product as “Spot, derivatives, crypto, and more — executed on a decentralized engine built for speed and scale.”

On that page, Bluefin says: “Since 2023, we’ve built on Sui with long term conviction. Its architecture uniquely enables the speed, scale, and reliability required for onchain markets.”

The official trading app at trade.bluefin.io is titled “Bluefin: Powering the New Financial Stack on Sui.”

The homepage links to twitter.com/bluefinapp. The account @bluefinapp is named Bluefin, and its profile links to trade.bluefin.io.

Bluefin’s learn page describes it as “a decentralized orderbook-based exchange built for both professional and first-time traders.” The page says the exchange “is backed by Polychain, SIG, Brevan Howard Digital, Tower Research and other leading firms.” It also says: “Our partnership with Sui, a team that originated at Facebook, is driven by our mutual mission to redefine the on-chain user experience.”

On October 10, 2026, @bluefinapp said “Sui DeFi continues to scale. On Bluefin, our lending markets cover digital assets and RWAs…”

On October 7, 2026, the same account posted “Day 1 of Sui Basecamp in the books!” That post is about attending an event. The site and the app are what identify Bluefin as a decentralized exchange built on Sui since 2023.
