+# Uniswap V2 Subgraph
+
+[Uniswap](https://uniswap.org/) is a decentralized protocol for automated token exchange on Ethereum.
+
+This subgraph dynamically tracks any pair created by the uniswap factory. It tracks of the current state of Uniswap contracts, and contains derived stats for things like historical data and USD prices.
+
+- aggregated data across pairs and tokens,
+- data on individual pairs and tokens,
+- data on transactions
+- data on liquidity providers
+- historical data on Uniswap, pairs or tokens, aggregated by day
+
+## Running Locally
+
+Make sure to update package.json settings to point to your own graph account.
+
+## Queries
+
+Below are a few ways to show how to query the uniswap-subgraph for data. The queries show most of the information that is queryable, but there are many other filtering options that can be used, just check out the [querying api](https://thegraph.com/docs/graphql-api). These queries can be used locally or in The Graph Explorer playground.
+
+## Key Entity Overviews
+
+#### UniswapFactory
+
+Contains data across all of Uniswap V2. This entity tracks important things like total liquidity (in ETH and USD, see below), all time volume, transaction count, number of pairs and more.
+
+#### Token
+
+Contains data on a specific token. This token specific data is aggregated across all pairs, and is updated whenever there is a transaction involving that token.
+
+#### Pair
+
+Contains data on a specific pair.
+
+#### Transaction
+
+Every transaction on Uniswap is stored. Each transaction contains an array of mints, burns, and swaps that occured within it.
+
+#### Mint, Burn, Swap
+
+These contain specifc information about a transaction. Things like which pair triggered the transaction, amounts, sender, recipient, and more. Each is linked to a parent Transaction entity.
+
+## Example Queries
+
+### Querying Aggregated Uniswap Data
+
+This query fetches aggredated data from all uniswap pairs and tokens, to give a view into how much activity is happening within the whole protocol.
+
+```graphql
+{
+  uniswapFactories(first: 1) {
+    pairCount
+    totalVolumeUSD
+    totalLiquidityUSD
+  }
+}
+```
+
+subgraph.yaml
+  修改factory地址和开始区块，如果开始区块距今不满足7天，explorer info前端会报错
+这个subgraph主要是为了获取区块基本信息，部署完swap的subgraph后，可以使用任意一个factory地址替换
+
+部署完成后可以供usd1swap movaswap同时使用，也可以部署两个分开用
+
+部署

+yarn codegen
