The super airdrop on SUI is initiated by Bluefin, and in 2025 SUI will retrace the wealth journey of SOL, which is why many people are interacting on SUI.

Recently, while interacting with the SUI ecosystem, I found that @bluefinapp launched the BluefinX feature, which allows for 0 slippage / 0 MEV / 0 Gas fee SWAP on SUI, making Bluefin the strongest trading infrastructure on SUI. Let's see what problems BluefinX solves?

1. What are the pain points of on-chain trading for SWAP?

The problems faced by swaps have existed for a long time, such as: severe slippage, a significant gap between the displayed price and the actual amount received; orders being front-run or sandwich attacked (many projects have made great efforts here, but the solution has not yet appeared); swap quotes being unsatisfactory or gas fees being too high, etc. We have been silently getting exploited by these issues.

This is easy to understand; many people have encountered situations of being sandwiched. For example, if placing an order of 1000U, in default mode, there will be 1M front-running. If the 'Anti-sandwich mode' is enabled, it becomes very difficult to execute trades. These are phenomena of being robbed in trading, which is why many people refer to a certain chain as a 'robbery chain', and this is not an exaggeration. In EVM, situations like these are being addressed by UniversalX, Debot, and BRC1115.

During the peak activity of SOL, almost all BOT tools on the network used Jito's nodes. Jito has performed very well in preventing sandwich attacks, but still cannot avoid issues like malicious nodes and abnormal bundle execution, leading to systemic risks for Jito's anti-sandwich nodes. Recently, there was a case where a user using the OKX wallet suffered a loss of thousands of U due to a low success rate of Jito's nodes in anti-MEV.

The newly launched KAMINO optimizes this aspect, allowing for swaps on Solana to be executed at the best price, achieving zero fees and zero slippage. It is supported by complex bots (searchers) provided by Pyth Express Relay, which ensure that users' transactions are completed at optimal prices.

KAMINO scans 5 routes during the transaction execution process, including Fluxbeam, Autobahn, Dflow, Jupiter, and Pyth Express. If Jupiter offers a better price, the searchers will choose it; if Pyth Express offers a better price, the system will choose it.

Both EVM and SOL have developers addressing industry pain points, but what about the MOVE ecosystem?

2. About BluefinX

BluefinX is a system based on RFQ that achieves 0 slippage / 0 MEV / 0 Gas fee, resulting in true trading fairness. It has already launched SUI / USDC, which is clearly a pilot project, and more trading pairs will be launched in the future.

Like KAMINO, BluefinX will intelligently choose the optimal path for each transaction. Whichever path offers a better price, the system will execute.

🔹Accurate pricing, zero slippage, what you see is what you get

🔹No fee trading

🔹Multiple party bidding, intelligently obtaining the best price across the network

🔹Comprehensive MEV protection

Thanks to Sui's sponsorship trading feature, liquidity providers can confirm final transactions through post-signing, solving issues such as anonymous user 'quote sniping' that RFQs often face, leading to tighter liquidity and better quotes.
From this AMA featuring Sui CTO Sam, Bluefin CTO Ahmad, and Wintermute quantitative trader Geo, it can be seen that in BluefinX anyone can become a quoting party and participate in bidding to acquire trading flow. In the future, it may even expand to on-chain liquidation rights bidding and other more complex scenarios.
