Unlike traditional pitch competitions, Sui Tank focused not on equity but on fostering creativity and community engagement. According to Sui Foundation, the event was a platform for builders to test ideas and receive feedback from industry leaders.

Pressure is a Privilege

With the potential to secure up to $30,000 per project, teams approached the stage with unique strategies to stand out. Zac Steele, CEO of Flashback, described the experience as nerve-wracking yet rewarding, emphasizing the privilege of pitching before a large audience and influential judges. Some teams lightened the mood with humor, while others employed creative storytelling to capture attention.

Innovative Pitches and Outcomes

DoubleUp Eats aimed to revolutionize food delivery with social elements and gamification, receiving encouragement to think bigger from the judges. Flashback, awarded the maximum $30,000, impressed with its innovative data management solution that integrates multiple cloud providers.

LockIn addressed the challenge of managing conversations across platforms, earning feedback to expand its reach. Meanwhile, Noodles, with its onchain analytics tool, captivated judges and secured $25,000 in funding thanks to its energetic presentation.

PlaiPin, inspired by gaming and personal expression, showcased a live demo, standing out as the only team to present a real-time product. Despite tough feedback, the team remained optimistic about future developments in the Sui ecosystem.

Beyond the Tank

The Sui Tank event transcended financial rewards, fostering a collaborative atmosphere where feedback and mentorship took precedence. Builders gained invaluable insights into their projects, enhancing their potential impact. As Zac Steele noted, the event’s unique format offered a richer experience than typical conferences, highlighting Sui’s vibrant and supportive community.

Sui Tank 2025 was not merely a competition but a celebration of innovation, collaboration, and community spirit, setting the stage for continued growth within the Sui ecosystem.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

Preliminary analysis of the Balancer V2 attack, which resulted in a loss of $120 million.

On November 3, the Balancer V2 protocol and its fork projects were attacked on multiple chains, resulting in a serious loss of more than $120 million. BlockSec issued an early warning at the first opportunity [1] and gave a preliminary analysis conclusion [2]. This was a highly complex attack. Our preliminary analysis showed that the root cause was that the attacker manipulated the invariant, thereby distorting the calculation of the price of BPT (Balancer Pool Token) -- that is, the LP token of Balancer Pool -- so that it could profit in a stable pool through a batchSwap operation. Background Information 1. Scaling and Rounding To standardize the decimal places of different tokens, the Balancer contract will: upscale: Upscales the balance and amount to a uniform internal precision before performing the calculation; downscale: Reduces the result to its original precision and performs directional rounding (e.g., inputs are usually rounded up to ensure the pool is not under-filled; output paths are often truncated downwards). Conclusion: Within the same transaction, the asymmetrical rounding direction used in different stages can lead to a systematic slight deviation when executed repeatedly in very small steps. 2. Prices of D and BPT The Balancer V2 protocol’s Composable Stable Pool[3] and the fork protocol were affected by this attack. Stable Pool is used for assets that are expected to maintain a close 1:1 exchange ratio (or be exchanged at a known exchange rate), allowing large exchanges without causing significant price shocks, thereby greatly improving the efficiency of capital utilization between similar or related assets. The pool uses the Stable Math (a Curve-based StableSwap model), where the invariant D represents the pool's "virtual total value". The approximate price of BPT (Pool's LP Token) is: The formula above shows that if D is made smaller on paper (even if no funds are actually withdrawn), the price of BPT will be cheaper. BTP represents the pool share and is used to calculate how many pool reserves can be obtained when withdrawing liquidity. Therefore, if an attacker can obtain more BPT, they can profit when withdrawing liquidity. Attack Analysis Taking an attack transaction on Arbitrum as an example, the batchSwap operation can be divided into three stages: Phase 1: The attacker redeems BPT for the underlying asset to precisely adjust the balance of one of the tokens (cbETH) to a critical point (amount = 9) for rounding. This step sets the stage for the precision loss in the next phase. Phase Two: The attacker uses a carefully crafted quantity (= 8) to swap between another underlying asset (wstETH) and cbETH. Due to rounding down when scaling the token quantity, the calculated Δx is slightly smaller (from 8.918 to 8), causing Δy to be underestimated and the invariant D (derived from Curve's StableSwap model) to be smaller. Since BPT price = D / totalSupply, the BPT price is artificially suppressed. Phase 3: The attackers reverse-swap the underlying assets back to BPT, restoring the balance within the pool while profiting from the depressed price of BPT—acquiring more BPT tokens. Finally, the attacker used another profitable transaction to withdraw liquidity, thereby using the extra BPT to acquire other underlying assets (cbETH and wstETH) in the Pool and thus profit.
