I still think a lot of people are underestimating how many new users Coinbase is going to bring onchain with Base.

I like to think of Base as Coinbase's (better) version of Binance Smart Chain (BSC) and we all know how much activity BSC saw during the bull & how that activity has sustained itself in the bear as well.

Have there been any signs of a CB->Base onboarding funnel yet?

Not yet but Coinbase has been quick to add direct bridges from their platform to other L2's (OP Mainnet and Arbitrum One) so I'm willing to bet that on launch day (August 9th) or near it, there will be native bridging from Coinbase to Base.

Too soon to tell. Base mainnet only recently went live and in a pretty limited way (for developers mainly) so you won’t see users flow in yet. No real/normal people use testnets.

In a couple months as the mainnet ecosystem develops this will be more a more valid question.
