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 Litedex Subgraph, and descriptions for the available fields.

To see an interactive sandbox of all entities see the Litedex 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.

Prod Factory​

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

Transaction​

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

Field Name	Value Type	Description
id	ID	BSC transaction hash
block	BigInt	block transaction was mined in
timestamp	BigInt	timestamp 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 Litedex 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 Name	Value Type	Description
id	ID	Transaction hash plus index in the transaction mint array
transaction	Transaction	reference to the transaction Mint was included in
timestamp	BigInt	timestamp of Mint, used to sort recent liquidity provisions
pair	Pair	reference to pair
to	Bytes	recipient of liquidity tokens
liquidity	BigDecimal	amount of liquidity tokens minted
sender	Bytes	address that initiated the liquidity provision
amount0	BigDecimal	amount of token0 provided
amount1	BigDecimal	amount of token1 provided
logIndex	BigInt	index in the transaction event was emitted
amountUSD	BigDecimal	derived USD value of token0 amount plus token1 amount
feeTo	Bytes	address of fee recipient (if fee is on)
feeLiquidity	BigDecimal	amount of liquidity sent to fee recipient (if fee is on)

Burn​

Burn entities are created for every emitted Burn event on the Litedex 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 Name	Value Type	Description
id	ID	Transaction hash plus index in the transaction burn array
transaction	Transaction	reference to the transaction Burn was included in
timestamp	BigInt	timestamp of Burn, used to sort recent liquidity removals
pair	Pair	reference to pair
to	Bytes	recipient of tokens
liquidity	BigDecimal	amount of liquidity tokens burned
sender	Bytes	address that initiated the liquidity removal
amount0	BigDecimal	amount of token0 removed
amount1	BigDecimal	amount of token1 removed
logIndex	BigInt	index in the transaction event was emitted
amountUSD	BigDecimal	derived USD value of token0 amount plus token1 amount
feeTo	Bytes	address of fee recipient (if fee is on)
feeLiquidity	BigDecimal	amount 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 Name	Value Type	Description
id	ID	transaction hash plus index in Transaction swap array
transaction	Transaction	reference to transaction swap was included in

logIndex	BigInt	event index within transaction
amountUSD	BigDecimal	derived amount of tokens sold in USD

Bundle​

The Bundle is used as a global store of derived BNB 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 BNB<->Stablecoin pair prices. This provides a strong estimate for the USD price of BNB that can be used in other places in the subgraph.

Field Name	Value Type	Description
id	ID	constant 1
bnbPrice	BigDecimal	derived price of BNB in USD based on stablecoin pairs

Historical Entities​

The subgraph tracks aggregated information grouped by days to provide insights to daily activity on BNB. 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.
