200x Faster. Seamlessly Efficient. Precision-Built for High-Performance Chains.
Bancor’s Arb Fast Lane, the most advanced arbitrage framework in decentralized finance, is now live on Sonic– 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 $1Billion in DeFi TVL.
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.
What Is the Arb Fast Lane?
The Arb Fast Lane 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:
1. A De-Facto Taker on Carbon DeFi
While a Carbon DeFi 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:
Zero slippage
Liquidity aggregation across all major DEXes
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.
2. A Chain-Wide Arbitrage Framework
With real-time scanning and execution, the Arb Fast Lane continuously optimizes market conditions by:
Identifying mispriced assets
Rebalancing liquidity
Keeping capital in constant motion
It’s the invisible infrastructure that sustains healthy, active markets.
The Breakthrough Behind the Speed
Most arbitrage systems rely on outdated optimization models that can’t keep up with modern market structures like concentrated liquidity AMMs.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.
Bancor’s solution?
Marginal Price Optimization
This proprietary approach bypasses the inefficiencies of convex optimization by focusing on the marginal price frontier — where optimal trades naturally occur.
The result?
200x faster execution
Scalability across any AMM model
Reliable performance under pressure
As Dr. Mark Richardson, Bancor’s Project Lead, explains:
“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.”

A new framework for arbitrage and routing in AMM driven markets v1.0”
Already Live Across Sonic’s Ecosystem
Upon launch, the Arb Fast Lane is integrated with:
SpookySwap (v2 & v3)
Shadow
DeFive
Oku
WAGMI
Graphene- VelocimeterDEX’s Carbon DeFi deployment
These integrations allow the Arb Fast Lane to execute trades across Sonic’s top liquidity sources, amplifying market efficiency and trading volume from day one.
Why It Matters for Sonic
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 from:
Liquidity fragmentation
Mispriced assets
Reduced execution quality
The Arb Fast Lane addresses these head-on by ensuring:
Price equilibrium across all major DEXes
Sustained trading activity
Efficient capital utilization

What’s Next?
The next major step is the full deployment of Carbon DeFi 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 Carbon DeFi is built for.
Carbon DeFi is a next-generation, orderbook-style DEX that empowers everyone from liquidity providers and traders to token projects and market makers, to design custom strategies with unparalleled precision. Whether executing a simple onchain limit order or creating automating recurring trades, Carbon DeFi unlocks:
Custom profit margins via Auto-compounding Concentrated Liquidity
Exact price execution through Limit Orders
Strategic scaling with Range Orders
Volatility capture through Automated Recurring Buy-Low, Sell-High Orders
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 outcome.
