 1 | Curve Subgraph
 2 | ==============
 3 | 
 4 | This subgraph provides information about the following Curve liquidity pools:
 5 | 
 6 | 1. Compound pool
 7 | 2. USDT pool
 8 | 3. PAX pool, with lending on yearn.finance
 9 | 4. Y Pool
10 | 5. BUSD pool
11 | 6. sUSD pool (v2)
12 | 7. renBTC pool
13 | 8. sBTC pool
14 | 9. HBTC pool
15 | 10. Tri-pool
16 | 11. GUSD metapool
17 | 12. HUSD metapool
18 | 13. USDK metapool
19 | 14. USDN metapool
20 | 15. LinkUSD metapool
21 | 16. MUSD metapool
22 | 17. RSV metapool
23 | 18. tBTC metapool
24 | 
25 | 
26 | Note: this subgraph doesn't provide transfer data about neither ERC20 nor LP tokens because that would imply indexing 
27 | a lot of events and would cost too much indexing time; it just covers basic token description including address, name,
28 | symbol and decimal precision.

33 | ## General system summary
34 | 
35 | ```graphql
36 | {
37 |   systemInfo(id: "current") {
38 |     # Total number of pools registered
39 |     poolCount
40 | 
41 |     # Total number of tokens registered as LP, composing or underlying coins
42 |     tokenCount
43 |   }
44 | }
45 | ```
46 | 
47 | 
48 | ## List all supported pools
49 | 
50 | ```graphql
51 | {
52 |   pools(orderBy: addedAt) {
53 |     # StableSwap contract address
54 |     address
55 | 
56 |     # Composing coins
57 |     coinCount
58 | 
59 |     coins {
60 |       address
61 |       name
62 |       symbol
63 |       decimals
64 |     }
65 | 
66 |     # Current balances
67 |     balances
68 | 
69 |     # LP token information
70 |     poolToken {
71 |       name
72 |       symbol
73 |       address
74 |     }
75 | 
76 |     # Pool parameters
77 |     A
78 |     fee
79 |     adminFee
80 |     virtualPrice
81 | 
82 |     # Pool's events
83 |     events {
84 |       # ...
85 |     }
86 |   }
87 | }
88 | ```
89 | 
90 | Note: pool events that are indexed include exchanges, add/remove liquidity, transfer ownership and pool parameters
91 |  changelogs (A coeff, fee and admin fee changes)
