Ethereum

Mainstream chain success is often determined by its wealth effects; much of this has been user-centric: chains who make their users the richest end up doing very well (obviously). 

But I think we are also  nearing a new form of sustainable wealth effects: 
“making app devs rich without needing them to dump tokens.”

How? 

Things like MEV taxes on OP stack chains (see what 
@MoonwellDeFi
 just did), app chains getting sequencer fees, vertical stacks for apps which enable more room for fees to be charged (eg Jupiter, Uniswap Wallet). 

Excited to see the progression of sustainable and differentiated revenue vehicles in crypto.

 For token holders, under clearer regulations, this can also be powerful because apps can choose to return excess revenue to buybacks or even staking rewards.
