Bancor's Arb Fast Lane, a cutting-edge arbitrage framework, is now operational on Sonic, a high-performance Layer-1 blockchain. This infrastructure enhances real-time price alignment, capital efficiency, and liquidity movement, boasting a 200x speed improvement. The Arb Fast Lane integrates with Sonic's top trading platforms, optimizing liquidity flow and market conditions. It functions as both a market optimization engine and a chain-wide arbitrage framework, addressing inefficiencies in DeFi ecosystems. The system employs Marginal Price Optimization for faster execution and scalability. Future plans include the deployment of Carbon DeFi on Sonic, offering advanced trading strategies and infrastructure.

Precision-Built for High-Performance Chains.</h3>Bancor’s <a href="http://bancor.network/arbfastlane">Arb Fast Lane</a>, the most advanced arbitrage framework in decentralized finance, is now live on <a href="https://www.soniclabs.com/">Sonic</a>– bringing real-time price alignment, capital efficiency, and continuous liquidity movement to one of the most performant Layer-1 chains in the ecosystem, and it’s nearly <a href="https://defillama.com/chain/Sonic">$1Billion in DeFi&nbsp;TVL</a>.With a 200x improvement in execution speed, unmatched precision, and integrations across Sonic’s top trading platforms, the Arb Fast Lane is already reshaping how liquidity flows.<h3>What Is the Arb Fast&nbsp;Lane?</h3>The <a href="http://bancor.network/arbfastlane">Arb Fast Lane</a> isn’t just an arbitrage bot. It’s an onchain market optimization engine– built to solve real inefficiencies that plague even the most liquid ecosystems.It serves two key functions:<h4>1. A De-Facto Taker on Carbon&nbsp;DeFi</h4>While a <a href="http://carbondefi.xyz">Carbon DeFi</a> deployment on Sonic hasn’t gone live just yet, the Arb Fast Lane is already laying the groundwork. Integrated directly into Carbon DeFi’s architecture, it acts as a solver system — executing trades across Sonic’s leading DEXes, resulting in Carbon DeFi strategy makers benefiting from:<ul><li>Zero slippage</li><li><a href="https://medium.com/bancor/how-to-gain-immunity-from-mev-sandwich-attacks-21d5a572157b">MEV sandwich attack&nbsp;immunity</a></li><li>Liquidity aggregation across all major&nbsp;DEXes</li></ul>Carbon DeFi and the Arb Fast Lane combined ensure orders are not just filled at the exact quoted price, but executed with unmatched precision and efficiency.<h4>2. A Chain-Wide Arbitrage Framework</h4>With real-time scanning and execution, the Arb Fast Lane continuously optimizes market conditions by:<ul><li>Identifying mispriced assets</li><li>Rebalancing liquidity</li><li>Keeping capital in constant&nbsp;motion</li></ul>It’s the <a href="https://medium.com/bancor/arbitrage-as-infrastructure-9fd3629cfc05">invisible infrastructure</a> that sustains healthy, active&nbsp;markets.<h3>The Breakthrough Behind the&nbsp;Speed</h3>Most arbitrage systems rely on outdated optimization models that can’t keep up with modern market structures like concentrated liquidity AMMs. They’re slow, computationally heavy, and prone to failure under real-time conditions.<a href="http://bancor.network">Bancor</a>’s solution?<h4>Marginal Price Optimization</h4>This proprietary approach bypasses the inefficiencies of convex optimization by focusing on the marginal price frontier — where optimal trades naturally occur.The result?<ul><li>200x faster execution</li><li>Scalability across any AMM&nbsp;model</li><li>Reliable performance under&nbsp;pressure</li></ul>As Dr. <a href="http://x.com/MBRichardson87">Mark Richardson</a>, Bancor’s Project Lead, explains:<blockquote>“By refocusing the problem on marginal price optimization, we’ve reduced a complex, high-dimensional task into a manageable root-finding problem– engineered for real-time DeFi.”</blockquote>*See Bancor’s latest Research Paper “Marginal Price Optimization– A new framework for arbitrage and routing in AMM driven markets&nbsp;v1.0”<a href="https://arxiv.org/html/2502.08258v1">Marginal Price Optimization A new framework for arbitrage and routing in AMM driven markets v1.0</a><h3>Already Live Across Sonic’s Ecosystem</h3><img src="https://static.sosovalue.com/sosovalue/2025/04/08/13a32ee4-102c-4147-af5c-28b8a615b106.png">Upon launch, the Arb Fast Lane is integrated with:<ul><li>SpookySwap (v2 &amp;&nbsp;v3)</li><li>Shadow</li><li>DeFive</li><li>Oku</li><li>WAGMI</li><li>Graphene- <a href="https://x.com/VelocimeterDEX">VelocimeterDEX</a>’s Carbon DeFi deployment</li></ul>These integrations allow the <a href="http://bancor.network/arbfastlane">Arb Fast Lane</a> to execute trades across Sonic’s top liquidity sources, amplifying market efficiency and trading volume from day&nbsp;one.<h3>Why It Matters for&nbsp;Sonic</h3>Sonic’s high throughput and developer-friendly design make it an ideal home for active DeFi ecosystems. But speed alone isn’t enough– without coordinated liquidity movement, even the fastest chains suffer&nbsp;from:• Liquidity fragmentation • Mispriced assets • Reduced execution qualityThe Arb Fast Lane addresses these head-on by ensuring:• Price equilibrium across all major DEXes • Sustained trading activity • Efficient capital utilization*See “How Arbitrage and Aggregated Liquidity Enhance Blockchain Ecosystems and Token Projects”<a href="https://blog.bancor.network/how-arbitrage-and-aggregated-liquidity-enhance-blockchain-ecosystems-and-token-projects-8ca6a9c19dac">https://medium.com/bancor/how-arbitrage-and-aggregated-liquidity-enhance-blockchain-ecosystems-and-token-projects-8ca6a9c19dac</a><h3>What’s Next?</h3>The next major step is the full deployment of <a href="http://carbondefi.xyz/trade">Carbon DeFi</a> on Sonic. A blockchain’s ecosystem needs more than fast execution– it needs advanced infrastructure that gives users control– over execution, pricing, and strategy creation.That’s exactly what <a href="http://carbondefi.xyz/trade">Carbon DeFi</a> is built&nbsp;for.Carbon DeFi is a next-generation, orderbook-style DEX that empowers everyone from liquidity providers and traders to <a href="https://bancor.network/use-cases/token-projects">token projects</a> and <a href="https://bancor.network/use-cases/market-makers">market makers</a>, to design custom strategies with unparalleled precision. Whether executing a simple onchain limit order or creating automating recurring trades, Carbon DeFi&nbsp;unlocks:<ul><li>Custom profit margins via Auto-compounding Concentrated Liquidity</li><li>Exact price execution through Limit&nbsp;Orders</li><li>Strategic scaling with Range&nbsp;Orders</li><li>Volatility capture through Automated Recurring Buy-Low, Sell-High Orders</li></ul>With Carbon DeFi and the Arb Fast Lane combined, it’s no longer just about trading– it’s about redefining the infrastructure behind it, and transforming the&nbsp;outcome.Learn more about each of Carbon DeFi’s trading strategy types by checking out the 4-part explainer series:<ul><li>Part 1 — <a href="https://blog.bancor.network/how-to-place-limit-orders-on-carbon-defi-08f39c4e8bb7">How to Place Limit Orders on Carbon&nbsp;DeFi</a></li><li>Part 2 — <a href="https://blog.bancor.network/how-to-scale-in-out-using-range-orders-on-carbon-defi-714f47adb2d9">How to Scale In/Out Using Carbon DeFi Range&nbsp;Orders</a></li><li>Part 3 — <a href="https://blog.bancor.network/how-to-automate-buy-low-sell-high-trades-on-repeat-on-carbon-defi-b4cdfe0a9c49">How to Automate Buy Low, Sell High Trades–on Repeat</a></li><li>Part 4 — <a href="https://blog.bancor.network/how-to-create-custom-liquidity-on-carbon-defi-2be7d1ca05d3">How to Create a Custom Liquidity on Carbon&nbsp;DeFi</a></li></ul>A Carbon DeFi deployment is coming to Sonic.
