Hi, great video. I have one question regarding executing any specific function in the contract that is deployed in the Arbitrum network. How do you call a function on the smart contract that is deployed in the Arbitrum network and how can you see the execution outcome? Thanks

Great video I'm having a problem though, can't import contract addresses from Dextools into Uniswap or depo.io on Arb Layer 2. Never had this problem in Layer 1....any ideas?
