“Seamless, automated cross-chain Arbitrage"

The problem CrossLink-Arbiter solves

🚩 The Problems

  • Cross-Chain Blindspot
    Arbitrage tools today operate within a single blockchain, leaving larger inter-chain price gaps unexploited.
  • 24/7 Market Surveillance
    Price spreads emerge and vanish in seconds; humans cannot monitor dozens of chains nonstop.
  • Integration Overhead
    Building cross-chain strategies demands stitching together disparate DEXes, bridges, oracles, and messaging layers.
  • Dynamic Risk Management
    Multi-chain gas fees, slippage, and liquidity shifts create moving targets for profit—and risk.
  • Capital Lockup
    Slow bridge finality ties up funds, reducing trade frequency and return on capital.

💡 How CrossLink-Arbiter Solves Them

  • Seamless Cross-Chain Execution
    Leverages Chainlink CCIP for trustless, cryptographically secured asset transfers and message passing between blockchains.
  • AI-Driven Market Intelligence
    Amazon Bedrock models continuously analyze price feeds, fee curves, and liquidity across chains to pinpoint high-alpha opportunities.
  • Fully Automated Workflow
    Chainlink Automation triggers watch-to-trade cycles, removing manual intervention and human error.
  • Real-Time Risk Adjustments
    Integrated gas-and-slippage analytics dynamically optimize trade parameters for maximum net returns.
  • Capital Efficient Cycles
    Sub-minute CCIP finality minimizes bridge lockup, enabling rapid, repeatable arbitrage loops.

By tackling each core barrier with purpose-built Chainlink and AWS AI services, ChainFlow AI transforms cross-chain arbitrage from an unreachable frontier into a high-speed, capital-efficient reality.

Challenges we ran into

🔧 Challenge and How we solved

  • No token pools existed on Sepolia testnets to test cross-chain arbitrage.
    Workaround: Deployed mock Uniswap V2 on both chains with seeded liquidity to create synthetic arbitrage opportunities.
    NOTE: On mainnet we’ll use real DEX pools across chains and feed live prices into Amazon Bedrock for AI-driven analysis and fully automated cross-chain arbitrage.

  • Couldn’t embed our Chainlink Functions JS directly in

    Consumer.sol

    —ran into on-chain RAM and gas limits.
    Workaround: Hosted the JS off-chain (e.g. on Render) and exposed it via a server API, then invoked that endpoint from the contract using Chainlink Functions.
