You still have a bit of time for DeFi Training Grounds - Week 3.
ONLY 13.569 members did it!!
The task is a bit more complicated than before, but here’s some help.
Create a deploy contract using Owlto, then verify it on Ink Explorer.
Stake some iETH on the network here:

You can use your Ink network to avoid the mainnet gas fees.
As for the questions, you'll find the solutions in the related group on Discord.

Good luck!
