Great article - Code and Kin project is very interesting !!

In your opinion - how much competition is there in the micropayments blockchain landscape?

For example, are micropayments only possible on Solana? Since Code is using an L2 on Solana - could other L2s on Ethereum for instance, also create micropayments infrastructure like Code has? What impact does the rollup versus stream of txs have on developer or user experience?

Is this part of the reason why DePin is built on Solana - need micropayments infra to make it work ?
