Powering Onchain Arbitrage Across Arbitrum
Bancor deploys the Arb Fast Lane Protocol on Arbitrum, bringing DeFi’s most advanced arbitrage infrastructure to one of the industry’s most active ecosystems! The result? A chain-wide upgrade to how liquidity flows, how capital moves, and how market equilibrium is maintained.
The Arb Fast Lane continuously scans Arbitrum’s leading DEXes, aligning prices and sustaining liquidity across venues. It doesn’t compete with other protocols– it supports them.
With 200x faster execution and extreme precision, Bancor’s arbitrage infrastructure is helping maintain a faster, healthier ecosystem– onchain, around the clock.
What Is the Arb Fast Lane Protocol?
It’s a high-performance, onchain execution engine built to resolve fragmented pricing across decentralized markets.
Designed for speed, precision, and chain-wide scope, it actively restores price equilibrium by scanning and executing arbitrage opportunities across major DEXes on the network — with precision down to the quadrillionths.
It serves two essential roles:
1. A Built-in Solver System for Carbon DeFi
Though Carbon DeFi, Bancor’s flagship DEX, isn’t yet deployed on Arbitrum, the groundwork is being laid. Once a Carbon DeFi deployment goes live on Arbitrum, every strategy created will be supported by the Arb Fast Lane’s built-in solver system. That means real-time, onchain execution.
It works like this:
• Once a strategy is created on Carbon DeFi, it becomes instantly visible to the Arb Fast Lane, which scans Arbitrum for available liquidity and profitable execution paths.
• From there, trades are fulfilled with precision — using chain-wide liquidity.
Together, Carbon DeFi and the Arb Fast Lane form a uniquely powerful system:
Makers get the exact price they quote.
No surprises.
No reliance on external takers.
No third-party dependencies.
2. A Chain-Wide Arbitrage Framework
Independently, the Arb Fast Lane plays a critical role in keeping Arbitrum’s markets healthy.
By executing trades across fragmented liquidity, the Arb Fast Lane:
• Aligns token prices across Arbitrum
• Keeps capital in motion
• Sustains activity across all major DEXes
It’s infrastructure that works behind the scenes– but powers everything in front of it.
The Technology Behind It
Most arbitrage models used in DeFi today struggle with speed and scale. They rely on outdated optimization models that were never designed for the fragmented, nonlinear dynamics of modern AMMs– especially concentrated liquidity environments and Carbon DeFi’s Asymmetric Liquidity.
Bancor’s approach — Marginal Price Optimization — zeroes in on the marginal price frontier, where optimal trades naturally occur. It skips the unnecessary complexity that bogs down traditional models, allowing for faster, more scalable execution.
The result?
• 200x faster execution
• Scalability across any AMM model
• Unmatched computational efficiency
It’s not just faster. It’s more precise, more stable, and more suited to the demands of modern DeFi.
Why Arbitrum?
Since its launch in 2021, Arbitrum has consistently ranked as a leading Layer 2 scaling solution and remains one of the most actively developed ecosystems in Ethereum’s rollup-centric roadmap.
Accoring to Messari, at the time of writing, Arbitrum boasts:
• Over $2.11 billion in TVL — 2nd largest Ethereum L2
• More than 2.2 million daily transactions
• Over 270,000 daily active addresses
• Nearly 800 dApps deployed
It’s the kind of high-throughput, high-liquidity environment where Bancor’s Arb Fast Lane thrives.
Where It’s Live
Upon launch, the Arb Fast Lane is already operating across many of Arbitrum’s top DEXes, including:
Uniswap v2, v3, and v4
PancakeSwap v2 and v3
SushiSwap v2 and v3
Arbswap v2
Smardex v2
Kaleido Cube v2
Spartadex v2
Zyberswap v2
And with more integrations on the way, the Arb Fast Lane will continue to adapt — ensuring every opportunity to trade against Carbon DeFi positions or optimize prices across the chain is captured.
What’s Next?
The Arb Fast Lane often arrives before Carbon DeFi– and for good reason.
Carbon DeFi is an onchain orderbook-style DEX that gives users the ability to build custom trading strategies with advanced control over how and when their assets move.
Behind the scenes, the Arb Fast Lane sources liquidity from across all major sources of liquidity on Arbitrum to help efficiently fill these strategies– bringing performance and efficiency to every execution.
Whether you’re a token project or market maker, liquidity provider or trader, you’ll benefit from Carbon DeFi’s features:
• Limit Orders for exact price execution
• Range Orders for strategic scaling
• Recurring Orders for automated buy-low, sell-high strategies
• Auto-compounding Liquidity for custom profit margins
The infrastructure is live. The groundwork is set. Carbon DeFi is next– built for users who demand control, not complexity.
