How this service works
Compare Aave v3 across all supported chains (Base, Ethereum, Arbitrum, Optimism, Polygon) for one token: where you earn the most supplying it, or pay the least borrowing it. Returns the best chain and the deposit/borrow APY on every chain. Live on-chain data.
Output
Returns the best chain for the requested comparison type, the token symbol, the protocol name, the best APY percentage, a per-chain breakdown of deposit and borrow APYs, and any relevant notes. Data is sourced live from on-chain Aave v3 markets.
Example use cases
Best yield chain for stablecoin lending
“I want to supply USDC on Aave v3 — which chain is currently paying the highest deposit APY, and what are the rates on each chain?”
Cheapest chain to borrow WETH
“I need to borrow WETH on Aave v3. Which chain has the lowest borrow APY right now, and what are the rates across Base, Ethereum, Arbitrum, Optimism, and Polygon?”
Multi-chain DAI yield optimization
“Compare the Aave v3 lending rates for DAI across all supported chains so I can move my funds to wherever I'll earn the most.”
Technical details
Endpoint
POSThttps://api.vextorium.com/aave-comparar-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a real-time, cross-chain comparison of Aave v3 lending or borrowing rates for a specific token. It aggregates live on-chain data from five chains in a single call, making it ideal for yield optimization, cost-of-capital analysis, or routing decisions without needing to query each chain separately.
Side effects
- Unsupported or misspelled token symbol returns empty or null markets
- Token not listed on a specific chain returns null APY for that chain
- On-chain RPC errors may cause stale or missing data for one or more chains
- Missing required 'token' field returns a validation error
- Invalid 'tipo' enum value causes request rejection
