March was a standout month for Bancor’s Arb Fast Lane — setting new transaction records, climbing the gas utilization charts, and cementing its role as DeFi’s most advanced arbitrage infrastructure and one of the most active, efficient systems onchain.
Recently, Primal Glenn, Business Development at Bancor, shared a detailed update on X highlighting the Arb Fast Lane’s accelerating performance and growing role in strengthening blockchain ecosystem health.
Doubled Transactions, Doubled Gas Consumption
March set a new benchmark for Bancor’s Arb Fast Lane on Sei:
169,515 transactions executed
Over 81 billion gas units consumed
This surge represents nearly double the monthly transactions and gas utilization compared to previous averages, where the Arb Fast Lane processed around 91,000 transactions and consumed approximately 40 billion gas per month between July and December 2024.
In March alone, the Arb Fast Lane ranked #34 in total transactions and #7 in gas utilization, reinforcing its growing role as critical infrastructure for the network.
5.55x More Transactions Than the Competition
In a highly competitive environment, the Arb Fast Lane undoubtedly stands out.
While Vertex Protocol led March’s gas usage, the Arb Fast Lane processed 5.55x more transactions during the same period — demonstrating its impressive operational efficiency.
The Arb Fast Lane’s continued expansion across decentralized exchanges (DEXs) reflects its growing influence, strengthening liquidity flows and price stability across the Sei ecosystem.
Behind the Numbers: What Is the Arb Fast Lane?
Behind these results is DeFi’s most advanced arbitrage infrastructure — a system purpose-built for efficiency, precision, and impact.
The Arb Fast Lane is Bancor’s arbitrage and routing system, seamlessly integrated into Carbon DeFi and operating across more than 10 blockchain ecosystems, including Sei, Celo, Sonic, Base, Ethereum, and COTI, to name a few.
It acts as a high-frequency taker, identifying and executing arbitrage opportunities across onchain liquidity venues with speed and accuracy.
While deeply connected to Carbon DeFi, the Arb Fast Lane also functions independently — helping synchronize prices across all major decentralized exchanges (DEXs) on each chain where it operates.
Strengthening Markets, One Block at a Time
Carbon DeFi isn’t the only system the Arb Fast Lane benefits. Its role extends beyond a single platform: strengthening liquidity flows, narrowing spreads, and driving healthier trading environments across entire ecosystems.
Efficient markets are critical for the long-term health of any blockchain ecosystem, and the Arb Fast Lane helps build healthier, more resilient ecosystems across every chain it touches.
Its impact can be seen in three major areas:
Price Stability: By arbitraging across DEXs, the Arb Fast Lane helps align prices, reducing gaps and minimizing volatility.
Higher Trading Volume: Stable pricing encourages more trading activity, which deepens liquidity and supports stronger token markets.
Network Growth: Sustained transaction flow and consistent gas utilization are signals
of a thriving blockchain — strengthening user confidence and attracting new projects.
By continuously identifying price discrepancies and executing trades, the Arb Fast Lane plays a vital role in maintaining stability, liquidity, and growth across the networks it operates on.

Accelerating Transaction Volumes and Execution Speed
Beyond March’s record-breaking transaction counts, cumulative data reveals a broader trend of steady growth in the Arb Fast Lane’s trading activity.
One notable pattern is the high volume of wrapping and unwrapping between SEI and WSEI — reflecting the structure of liquidity pools across the Sei ecosystem, where some venues require SEI while others operate with wrapped assets, creating a continuous flow of transactions to maintain price alignment.
March also marked a significant leap forward in the Arb Fast Lane’s capabilities.
Bancor researchers recently introduced:
“Marginal Price Optimization: A New Framework for Arbitrage and Routing in AMM-Driven Markets v1.0.”
The Arb Fast Lane demonstrates a 200x speed improvement compared to previously published algorithms — and continues to receive ongoing upgrades and advancements to further enhance its performance.
With both transaction volumes and execution speed accelerating, the Arb Fast Lane is not only keeping pace with growing DeFi activity — it’s setting a new benchmark for performance.
The Road Ahead
With its latest upgrades now fully integrated, the Arb Fast Lane is capturing arbitrage opportunities faster and more efficiently than ever before.
Additional articles and technical resources will soon offer a deeper look into the research behind these advancements — providing insight into how Bancor’s arbitrage infrastructure is setting a new standard for onchain market performance.
Closing Note
For blockchains and token projects looking to strengthen liquidity efficiency, price stability, and trading depth, the Arb Fast Lane’s impact on Sei offers a powerful proof point — and a glimpse into what’s possible when arbitrage evolves beyond a trading technique and becomes a core pillar of blockchain infrastructure— stronger, more efficient markets, one transaction at a time.
