# Lending Market Balances

> Balance in USD for one token in one lending market, split by balance type (deposit or borrow) and subtype (supply, collateral, variable or fixed borrow). Each series is one market token balance, keyed by protocol, product, chain, market, token, balance type and balance subtype. Finer than lending-protocols-by-product-market, with many series per market, so name the balances you need.

One row per lending market balance, the finest grain of the lending data, keyed by protocol, product, chain, market, token, balance type and balance subtype: the market and token, the parent protocol and product, chain and the mapped protocol, project and network records. The id is the series key of the lending-market-balances timeseries model.

| | |
| - | - |
| Access | Lending-protocols-dataset |
| Tabular model | `lending-market-balances`: primary key `id` |
| Timeseries model | `lending-market-balances`: intervals `1d`, series key `id` (Lending Market Balance ID), series must be named (up to 20 per call) |

## Metrics

1 metric. Use the `Field` value in `selections`; every point starts with the timestamp and continues in this order.

| Field | Name | Type | Unit | Description |
| - | - | - | - | - |
| `balanceUSD` | Balance (USD) | float64 | | The balance in USD of the token for this market, balance type and subtype. |

## Columns

Use the `Field` value in `selections`, `sortBy`, and as the base of a filter parameter (`Field` plus one of its `Filters` suffixes).

| Field | Type | Filters | Sort | Description |
| - | - | - | - | - |
| `id` | string | `Eq`, `IsOneOf` | | The series key of the lending-market-balances timeseries model, the parent slug, product slug, chain, market key, token key, balance type and balance subtype, joined with underscores. (primary key) |
| `name` | string | `Eq`, `IsOneOf`, `Contains` | default | The display name of the balance, the market name, token symbol and balance subtype (or type). |
| `slug` | string | `Eq`, `IsOneOf` | yes | The parent protocol's project slug, the slug used for the same protocol across the API. |
| `parentSlug` | string | `Eq`, `IsOneOf` | yes | The parent protocol's short name, the id in lending-protocols (aave). |
| `productSlug` | string | `Eq`, `IsOneOf` | | The product or version within the parent protocol (aave-v3). |
| `chain` | string | `Eq`, `IsOneOf` | | The short name of the chain the market lives on (ethereum, bnb, solana). |
| `marketID` | string | `Eq`, `IsOneOf` | | The market or pool address; null when the protocol does not label markets. |
| `marketName` | string | `Eq`, `IsOneOf`, `Contains` | | The market display name. |
| `marketType` | string | `Eq`, `IsOneOf` | | The market type where the protocol distinguishes one (for example core, pooled or credit\_vault); null otherwise. |
| `tokenAddress` | string | `Eq`, `IsOneOf` | | The token contract address (the mint address on Solana); null when unlabeled. |
| `tokenSymbol` | string | `Eq`, `IsOneOf`, `Contains` | yes | The token's ticker symbol. |
| `balanceType` | string | `Eq`, `IsOneOf` | | Whether the balance is a deposit or a borrow. |
| `balanceSubtype` | string | `Eq`, `IsOneOf` | | The finer balance classification (for example supply, collateral, variable\_borrow or fixed\_borrow); null for protocols that do not distinguish one. |
| `protocolSlug` | string | `Eq`, `IsOneOf` | | The slug of the protocol record mapped to the product; null when unmapped. |
| `protocolName` | string | `Eq`, `IsOneOf` | | The name of the protocol record mapped to the product; null when unmapped. |
| `projectID` | string | `Eq`, `IsOneOf` | | The identifier of the parent protocol's project record. |
| `networkID` | string | `Eq`, `IsOneOf` | | The chain's networkID in the blockchains model; null when unmapped. |
