During our ongoing formal verification with our partners at @AsymptoticTech, of integer-mate – a core math library used across many Sui protocols – we identified an edge case where signed subtraction could behave incorrectly when the second operand reached its minimum possible value. While the bug had no impact on Bluefin’s systems, the uncertainty around how others might use the library prompted us to act quickly - preparing an improved implementation with our security partners and working closely with Sui Foundation to spread the word to affected DEXs so they could fix this bug. Thank you to everyone involved: @AsymptoticTech for the deep dive and spotting the edge case, @osec_io’s @NotDeGhost for jumping in on verification, and @SuiNetwork for leading a swift and coordinated response. This is the kind of collaboration that sets Sui apart. Security is an ongoing commitment, and this quick identification and solve shows we're in this together. We’ll continue investing in formal verification, architecture reviews, and ecosystem-wide coordination to raise the bar for secure and verifiable DeFi.
