Curve Subgraph

==============

This subgraph provides information about the following Curve liquidity pools:

1. Compound pool

2. USDT pool

3. PAX pool, with lending on yearn.finance

4. Y Pool

5. BUSD pool

6. sUSD pool (v2)

7. renBTC pool

8. sBTC pool

9. HBTC pool

10. Tri-pool

11. GUSD metapool

12. HUSD metapool

13. USDK metapool

14. USDN metapool

15. LinkUSD metapool

16. MUSD metapool

17. RSV metapool

18. tBTC metapool

Note: this subgraph doesn't provide transfer data about neither ERC20 nor LP tokens because that would imply indexing 

a lot of events and would cost too much indexing time; it just covers basic token description including address, name,

symbol and decimal precision.
