Entities

Entities define the schema of the subgraph, and represent the data that can be queried. Within each entity are sets of fields that store useful information related to the entity. Below is a list of the available entities within the Uniswap Subgraph, and descriptions for the available fields.

To see an interactive sandbox of all entities see the Graph Explorer.

Each entity is defined with a value type, which will always be a base AssemblyScript type, or a custom type provided by The Graph's custom TypeScript library. For more information on value types see here.

Uniswap Factory#

The Uniswap Factory entity is responsible for storing aggregate information across all Uniswap pairs. It can be used to view stats about total liquidity, volume, amount of pairs and more. There is only one UniswapFactory entity in the subgraph.

Field NameValue TypeDescription

User#

A user entity is created for any address that provides liquidity to a pool on Uniswap. This entity can be used to track open positions for users. LiquidyPosition entities can be referenced to get specific data about each position.

Field NameValue TypeDescription
idIDuser address
liquidityPositions[LiquidityPosition]array of all liquidity positions user has open

LiquidityPositiion#

This entity is used to store data about a user's liquidity position. This information, along with information from the pair itself can be used to provide position sizes, token deposits, and more.

Field NameValue TypeDescription
idIDuser address and pair address concatenated with a dash
userUserreference to user
pairPairreference to the pair liquidity is being provided on
liquidityTokenBalanceBigDecimalamount of LP tokens minted for this position

Transaction#

Transaction entities are created for each Ethereum transaction that contains an interaction within Uniswap contracts. This subgraph tracks Mint, Burn, and Swap events on the Uniswap core contracts. Each transaction contains 3 arrays, and at least one of these arrays has a length of 1.

Field NameValue TypeDescription
idIDEthereum transaction hash
blockNumberBigIntblock transaction was mined in
timestampBigInttimestamp for transaction
mints[Mint]array of Mint events within the transaction, 0 or greater
burns[Burn]array of Burn events within transaction, 0 or greater
swaps[Swap]array of Swap events within transaction, 0 or greater

Mint#

Mint entities are created for every emitted Mint event on the Uniswap core contracts. The Mint entity stores key data about the event like token amounts, who sent the transaction, who received the liquidity, and more. This entity can be used to track liquidity provisions on pairs.

Field NameValue TypeDescription
idIDTransaction hash plus index in the transaction mint array
transactionTransactionreference to the transaction Mint was included in
timestampBigInttimestamp of Mint, used to sort recent liquidity provisions
pairPairreference to pair
toBytesrecipient of liquidity tokens
liquidityBigDecimalamount of liquidity tokens minted

amount1BigDecimalamount of token1 provided
logIndexBigIntindex in the transaction event was emitted
amountUSDBigDecimalderived USD value of token0 amount plus token1 amount
feeToBytesaddress of fee recipient (if fee is on)
feeLiquidityBigDecimalamount of liquidity sent to fee recipient (if fee is on)

Burn#

Burn entities are created for every emitted Burn event on the Uniswap core contracts. The Burn entity stores key data about the event like token amounts, who burned LP tokens, who received tokens, and more. This entity can be used to track liquidity removals on pairs.

Field NameValue TypeDescription
idIDTransaction hash plus index in the transaction burn array
transactionTransactionreference to the transaction Burn was included in
timestampBigInttimestamp of Burn, used to sort recent liquidity removals
pairPairreference to pair
toBytesrecipient of tokens

feeToBytesaddress of fee recipient (if fee is on)
feeLiquidityBigDecimalamount of tokens sent to fee recipient (if fee is on)

Swap#

Swap entities are created for each token swap within a pair. The Swap entity can be used to get things like swap size (in tokens and USD), sender, recipient and more. See the Swap overview page for more information on amounts.

Field NameValue TypeDescription
idIDtransaction hash plus index in Transaction swap array
transactionTransactionreference to transaction swap was included in

amount0OutBigDecimalamount of token0 received
amount1OutBigDecimalamount of token1 received
toBytesrecipient of output tokens
logIndexBigIntevent index within transaction
amountUSDBigDecimalderived amount of tokens sold in USD

Bundle#

The Bundle is used as a global store of derived ETH price in USD. Because there is no guaranteed common base token across pairs, a global reference of USD price is useful for deriving other USD values. The Bundle entity stores an updated weighted average of ETH<->Stablecoin pair prices. This provides a strong estimate for the USD price of ETH that can be used in other places in the subgraph.

Field NameValue TypeDescription
idIDconstant 1
ethPriceBigDecimalderived price of ETH in USD based on stablecoin pairs

Historical Entities#

The subgraph tracks aggregated information grouped by days to provide insights to daily activity on Uniswap. While time travel queries can be used for direct comparison against values in the past, it is much more expensive to query grouped data. For this reason the subgraph tracks information grouped in daily buckets, using timestamps provided by contract events. These entities can be used to query things like total volume on a given day, price of a token on a given day, etc.

For each DayData type, a new entity is created each day.

UniswapDayData#
