Primarily by giving more options and having more resources working on it. Like Rob said, we simply do not know, and the only way to find out is to test. I don’t have much more to add than what I’ve said in previous responses in this thread: I understand why people see a Statemint DEX as detrimental, but I believe that not having a Statemint DEX is hurting Polkadot.
I quite agree with what @lucasvo wrote in Why not just Statemint needs an AMM but (likely) every parachain and we should do our best to agree on a shared interface. To accomplish this, we need to stop thinking of liquidity as a static value that’s divvied up among some parachains.
Speaking generally, not just about liquidity, but people/projects with a “slice of the pie” mentality will not succeed in the long run. If we only see things in terms of fighting over what value (whether it’s liquidity, number of Substrate developers, etc.) exists at a particular snapshot in time, then as a whole we have already lost. We need to build more and attract more value for Polkadot to succeed. Like @shawntabrizi said in Statemint Update / Roadmap - #35 by shawntabrizi, if you work on a dedicated DEX/DeFi parachain, I really do not see how this is a competitor.
I am not talking about “direct to user” UX here, there is a lot more to UX than that. If you go back to the original post, a lot of the motivation in the roadmap is actually to abstract Statemint away from the end user. The improved UX here comes from:
- Ability to pay fees (securely) in more assets
- → Allows other UIs/wallets to create better UX
- → Creates better UX for parachain devs to interact with Statemint over XCM
- Ability to access parachain native tokens
- → Allows parachains to create better onboarding from DOT into their ecosystem, even if they are not listed on a centralized exchange.
- → Allows centralized exchanges to support more assets within Polkadot without running more infrastructure, and
- → Allows users to “bypass” Statemint by withdrawing direct from a centralized exchange to a parachain.
Well, nothing, it’s another parachain. I don’t understand the “compared to other parachains” part. Having better UX and onboarding in the Polkadot ecosystem is not a mutually exclusive design area. Just because UX on Statemint improves does not mean that UX on other parachains is hurt.
