“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.
