Portals - Market Data

[gomesalexandre]

Overview

See this comment: https://github.com/shapeshift/web/issues/6981#issuecomment-2206869446

4. What about market-data?

Historical market data isn't going to be available, but that's nothing different than e.g how we used to do UNI-V2 opportunities - we absolutely can and should upsert the current price of all https://api.portals.fi/v2/tokens tokens in the market-data slice

References and additional details

https://api.portals.fi/v2/tokens which contains spot price

Acceptance Criteria

• Spot price is fetched and upserted for LP tokens JIT with whichever smart pattern we can come up with. There are ~50k assets totals supported by Portals, which we will generate with the generation script in https://github.com/shapeshift/web/issues/7303. We obviously can't afford to run it at runtime. Usefuls patterns could be prefetching on assets scroll with https://tanstack.com/query/v4/docs/framework/react/guides/prefetching, or simply JIT when selecting an asset
• If there is already market data for a token (meaning it's either a token that already had market-data from other sources, not Portals, or is a Portals asset with its spot price already fetched), market data is not refetched JIT and business is as usual here

discussion from grooming on monday: provider vs JIT - JIT much less LOE but not reusable for showing in portfolio / defi positions

@0xApotheosis should have this work done in the custome import token implementation and we can use that for learnings to apply here.

[0xean]

estimates are based on JIT approach, we can improve as we know more

[0xean]

@0xApotheosis working on implementation w custom tokens that can also be leveraged for this

fyi @gomesalexandre historical data is now available https://api.portals.fi/docs#/Supported/SupportedController_getTokenHistory
