I have WETH on Polygon, but I want to lend MATIC on Aave. How can I do this? And what about fees?

  1. 1.
    Make a 2 cubes combo with a swap cube and a deposit cube.
  2. 2.
    Click the “Approve” button to grant Furucombo access to move your WETH tokens.
  3. 3.
    Click the “Send” button to actually convert your WETH to MATIC and deposit to Aave simultaneously.
For your reference, it costs around US$0.001 (1 gwei) to complete the transaction on Polygon on the day of writing. While it costs about US$1.1 (12 gwei) on Ethereum to complete a similar transaction. That is 1000+ times less using Polygon!
What other advantages?
On top of the fact that the gas fees are significantly lower on Polygon compared to Ethereum, Polygon now offers many incentives to encourage new users onboard. For example, Polygon provides extra MATIC bonuses to Aave lenders and borrowers. So are the liquidity providers on Curve, Quickswap, and Sushiswap!
