This is another quest from the Arbitrum Hub on Layer3, now on Camelot DEX. 💱 

https://app.layer3.xyz/quests/arbitrum-hub-camelot?ref=misternorris.eth

You need to have more than 100 CUBEs to access this quest. Then, you need to add liquidity to the USDe/USDC pair (I used some ARBs gained in the last quest to do this). 😉 

After you complete it, you will earn a CUBE, 0.4 ARB, and 100 XP. 🤑 

Hurry, there are only 10,000 available spots! 💪

I added liquidity but still can't validate the quest

Crypto, DeFi and NFT's.

If you follow me I follow you fren!

I did it the same way as you, in AUTO mode and with GAMMA as the provider. I added approximately $1 USD of liquidity and I was able to validate the quest. I don't think the issue is the amount of liquidity you added, since according to Layer3, there is no minimum.

Maybe you should wait a few minutes and update the Camelot page as well as Layer 3, which often have errors that are fixed by updating.
