- Only pools with large market caps will be allowed.
- Common router only accepts token combinations, so that's how it will be stored in the contract.
- Each token in pools must have a DIA price symbol associated with it.

- Free and available.
- Can't specify a time so it may have to come down to any user being able to call the record final price function.
- In case there's a problem with the oracle, will need a manual option that can be set after a certain amount of time.
- Will need to have a think about the price of the token in terms of charting and front end.
The NFT is a bonus and separate to this contract.
Was thinking the easiest way to go about it would be to:
- create a collection on artzero.
- Whitelist the competitors.
- Allow free mint for competitors after competition starts.
- Depending on the number of competitors and NFTs, do a public sale for the rest.
During whitelist phase, the price would be 0, then public whatever you reckon.
To show a leaderboard:
- Need all the competitors and a tracking of their token balances.
- Need the price from the DIA oracle.
So that we don't have to start or modify a squid every time a tournament starts, it'd be best to have one contract instance that can control multiple tournaments.
