Two trader brothers earned 5 million USD thanks to the number 1 arbitrage bot on HyperEVM

In the context of the highly volatile cryptocurrency market in March 2025, when the overall sentiment seemed to be declining, two anonymous traders known as CBB discovered a potential goldmine: the price difference between HyperEVM and the Hyperliquid derivatives trading exchange.

Starting from a simple idea – running an arbitrage bot ( between two platforms to optimize the “farming” of potential rewards, even accepting the risk of initial costs – this strategy quickly turned them into dominant players, earning an astonishing profit of ) million USD along with a trading volume on Hyperliquid reaching $12.5 billion USD in just 8 months.

Delay Mining Strategy: The Foundation of Profit

The price discrepancy opportunity arises from the technical mechanism of HyperEVM. With a block creation time of 2 seconds, the price of token $5 on HyperEVM's DEX $HYPE AMM( updates slower than the spot market on Hyperliquid. This 2-second gap creates a temporary “arbitrage,” allowing their bot to buy HYPE at a low price on one exchange and sell it at a high price on the other.

Initially, the bot only executed trades when the net profit after fees exceeded 0.15%. In just the first few days, the pair achieved a daily trading volume of around $200k–300k on Hyperliquid and began to turn a profit.

Outperforming Competitors Through Fee and Speed Optimization

Intense competition has emerged quickly. To get ahead of its two main rivals, CBB made a strategic move in April: leveraging the staking program ) of Hyperliquid to receive a 30% discount on transaction fees. This move allowed them to reduce the required profit threshold to just 0.05%, putting immense pressure on rivals who cannot compete at such a low profit margin.

This strategy has been a resounding success. In just two weeks, the trading volume of CBB surpassed $HYPE million, forcing competitors to halt operations. At its peak, they recorded a profit of $120,000 USD in just 24 hours.

Addressing the Challenge of Scaling

When the trading volume skyrockets, the bot begins to encounter transaction congestion issues $500 txs( on HyperEVM due to the gas limit per block. To maintain dominance, they have implemented sophisticated improvements:

Major Breakthrough: Transition to Maker and Integration of Perps

Two major upgrades have made a decisive difference, helping CBB's bot maintain its leading position even when “whales” like Wintermute enter the market:

1. Become a Maker on Hyperliquid: Instead of always initiating arbitrage trades as a taker on HyperEVM, they started placing maker orders )liquidity providers( on Hyperliquid. This strategy helps them reduce transaction fees by an additional 0.0245% and seize rare opportunities from “wick candles” )wick candles(. Although the risk of not being able to match counterpart orders on HyperEVM is high, after many days of complex adjustments, they have resolved the asset imbalance issue, achieving a trading volume 20 times that of their competitors.
2. Integrating Perpetual Futures )Perpetual Futures(: Despite having no prior experience with leverage trading, CBB has noticed trading volume and transaction fees better at )0.019% compared to 0.0245%( in the $HYPE perpetual contract market. More importantly, using perps allows them to further exploit price arbitrage opportunities when HYPE perp trades at a premium )higher price( or discount )lower price( compared to the spot price, while also earning an additional $600,000 USD just from the )funding fee(.

With a clearly defined role between the older brother as a programming engineer and the younger brother as a strategy configuration expert, the CBB duo has spent over 2,000 hours developing and improving the bot. They describe this process as a never-ending race, even having to take time off in Istanbul and Bodrum to “lock themselves” in upgrading the bot.

After 8 months of dominance, accounting for 5% of total trading volume on Unit, and having paid $1.2 million USD in gas fees on HyperEVM ), equivalent to 20% of the platform's total gas fees(, CBB has decided to withdraw upon noticing a decline in market share starting in October.

The story of CBB is a typical example of the enormous profitability from combining sharp strategic thinking, continuous technical optimization, and flexible adaptability in the harsh cryptocurrency algorithmic trading market. Their success is not only reflected in the figure ) million USD but also in shaping a new high-speed game in the Hyperliquid and HyperEVM ecosystem.
