I now basically use the mainnet like a vault and L2 like an everyday wallet—saving gas and, frankly, saving my peace of mind. For small interactions, I go to L2. If I really need to use the mainnet, I only do two things: bridge back, or transfer large amounts to a cold wallet. In plain terms, don’t try to have both the best experience and the lowest fees at the same time—ordinary people can’t carry that burden.

Yesterday, I swapped tokens on Arbitrum and saw an approve for address 0x9c…dE1 with an infinite allowance. I changed it manually to use only as much as needed in each batch—I'd rather confirm a few more times at once. Lately, the narrative around AI Agents and automated trading has been quite hot, but the more “automatic” it is, the more you have to watch permissions: where the private key is stored, whether a contract can freely take money, and whether failed rollbacks still charge fees… I’ve been fined before, so I really don’t dare to hand my wallet over to a “smart program.” For now, that’s it—move less, live more.
