# Peg Stability Backings

> Daily backing in USD held by one peg stability facility in one backing token (USDC, USDT and other stablecoins, or the RWA an ilk holds). Each series is one facility backing token, keyed by protocol, chain, facility and token.

One row per peg stability facility backing token, keyed by protocol, chain, facility and token: the parent protocol and product, chain, facility, token and the mapped protocol, project and network records. The id is the series key of the peg-stability-backings timeseries model.

| | |
| - | - |
| Access | Stablecoins-dataset |
| Tabular model | `peg-stability-backings`: primary key `id` |
| Timeseries model | `peg-stability-backings`: intervals `1d`, series key `id` (Peg Stability Backing ID), every series available in one call |

## Endpoints

## 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 |
| - | - | - | - | - |
| `backingUSD` | | | | |

## 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 |
| - | - | - | - | - |
| `chain` | string | | | The short name of the chain (ethereum, base, solana). |
| `facilityID` | string | | | The facility's identifier within its protocol (a Maker-style ilk for Sky and USDD, the PegKeeper address for Curve). |
| `facilityName` | string | | | The facility's display name. |
| `id` | string | | | The series key of the peg-stability-backings timeseries model, the parent slug, chain, facility id and token address, joined with underscores. |
| `name` | string | | | The display name of the series, the facility name and backing token symbol. |
| `networkID` | string | | | The chain's networkID in the blockchains model; null when unmapped. |
| `parentSlug` | string | | | The parent protocol's short name. |
| `productSlug` | string | | | The product or version within the parent protocol. |
| `projectID` | string | | | The identifier of the parent protocol's project record; null when unmapped. |
| `protocolName` | string | | | The name of the protocol record mapped to the product; null when unmapped. |
| `protocolSlug` | string | | | The slug of the protocol record mapped to the product; null when unmapped. |
| `slug` | string | | | The parent protocol's project slug, the slug used for the same protocol across the API; null when unmapped. |
| `tokenAddress` | string | | | The token contract address (the mint address on Solana); null when unlabeled. |
| `tokenSymbol` | string | | | The token's ticker symbol. |
