> Meanwhile, trades on blockchains are often expensive. This is quickly being solved with modular blockchain architectures. If you haven't read about zkrollups yet I suggest looking into that. While still in early stages transaction throughput on Ethereum has scaled from ~13 tx/s to ~2500 tx/s with rollups.

First you pay hundreds to bridge to a rollup, then you don't get to interact with any defi protocols since they're all on mainnet.

  The "hundreds to bridge" is a worst case figure that most folks would only do if they had to bridge in the midst of a crash and needed to add capital to avoid liquidation on an L2 position. If you time it right it's more like $40-50. Not great, obviously, but it isn't "hundreds". And ultimately, the problem goes away when centralized exchanges provide direct on-ramps to L2's -- which is already happening with some smaller exchanges.

    If you're paying $40-$50 dollars per trade, how is that "solving the problem of expensive transfers"?

      It's a one time bridge. Bridge once, and then the transactions with the funds you have on l2 can be traded or borrowed against for vastly cheaper then mainnet. If you want or have a need to add more funds to trade with, then it's an additional bridging fee, but not every tx is $40-50.

        It seems like there’s an underlying assumption that you’re going to trade often. Paying a one-time fee and making it up in volume doesn’t seem very appealing for people who don’t trade that much anyway? Is this just for day traders?

        If you don't need to make very many transactions then maybe the high fees on L1 aren't an issue anyway.

        You're competing with free trades on the stock market though

  If you are coming from fiat then you can often withdraw to l2 directly from there if you research first. Liquidity is still an issue but alternatively you can use cheaper yet active chains like Sol, Avax or Polygon.

There are also EVM-compatible coins now with better L1 scalability and defi swaps and bridges between ETH and these coins
