Arbitrum, Polygon, and More — Cross-Chain Yield Aggregation — Routing Capital Across Ethereum, Arbitrum, Polygon, and More
The highest yield opportunities exist across multiple chains simultaneously. A cross-chain yield aggregator routes capital to the best risk-adjusted opportunity regardless of chain. Here is the architecture. Current yields (illustrative, verify in real time): Aave USDC on Ethereum: 4.2% APY Aave USDC on Arbitrum: 5.8%...

For large capital pools (>$1M): yes — even a 1% APY improvement on $1M is $10,000/year, easily exceeding bridge costs and development overhead. For retail users (under $50,000): transaction costs often exceed yield benefits. The economically sensible minimum for active cross-chain rebalancing is approximately $100,000 per rebalancing operation.
