# Supported Stablecoin Price Feeds

> All stablecoin price feeds currently live on IFÁ Labs, with asset IDs, per-network availability, fiat backing details, and how to request new feeds.

IFÁ Labs provides dedicated on-chain price feeds for a curated set of stablecoins, prioritizing both global liquidity assets and local stablecoins critical to emerging economies. All feeds are USD-denominated and use consistent asset IDs across every supported network.

## Current Price Feeds

| Asset        | Description                   | Category        | Asset ID (bytes32)                                                   |
| ------------ | ----------------------------- | --------------- | -------------------------------------------------------------------- |
| **USDT/USD** | Tether                        | Global          | `0x6ca0cef6107263f3b09a51448617b659278cff744f0e702c24a2f88c91e65a0d` |
| **USDC/USD** | USD Coin                      | Global          | `0xf989296bde68043d307a2bc0e59de3445defc5f292eb390b80d78162c8a6b13d` |
| **CNGN/USD** | Nigerian Naira Stablecoin     | Emerging Market | `0x83a18c73cf75a028a24b79cbedb3b8d8ba363b748a3210ddbcaa95eec3b87b3a` |
| **ZARP/USD** | South African Rand Stablecoin | Emerging Market | `0x12373a3b1c4827c84bf6d7b11df100442695d0abfdb7a20d30a41d67d58e75a8` |
| **BRZ/USD**  | Brazilian Real Stablecoin     | Emerging Market | `0xbc60b55b031dce1ee5679098bf2f35d66a94a566124e2b233324d2bafcc6d5b5` |

<Info>
  ETH/USD is included as a reference asset to enable derived pair calculations between stablecoins and ETH — not as a primary price feed target. IFÁ Labs remains stablecoin-first.

## Network Availability

All feeds listed above are available on every currently supported network:

| Network            | Status | Notes                         |
| ------------------ | ------ | ----------------------------- |
| Base Mainnet       | Live   | Primary production deployment |
| Base Sepolia       | Live   | Recommended for testing       |
| AssetChain Testnet | Live   | RWA-focused ecosystem         |

As IFÁ Labs expands to new chains, all existing feeds will be available on day one of each deployment.

## Derived Pairs

Beyond individual USD feeds, IFÁ Labs supports derived pair calculations — for example, pricing CNGN directly against USDT, or ZARP against USDC, without requiring a dedicated feed for each combination.

Derived pairs are computed on-chain using the `getPairbyId` function:

```solidity theme={null}
// Get CNGN priced in USDT terms
DerivedPair memory pair = oracle.getPairbyId(
    CNGN_ASSET_ID,
    USDT_ASSET_ID,
    PairDirection.Forward
);
```

This enables protocols to work with any combination of supported assets without waiting for a direct feed to be listed. See the [Function Reference](/function-reference) for full derived pair API details.

## Requesting New Feeds

New assets are added based on ecosystem demand. IFÁ Labs prioritizes feeds for stablecoins that meet the following criteria:

* Verified backing and transparent reserves
* Demonstrated on-chain or real-world adoption
* Clear use case from an existing or prospective protocol

To request a new feed, reach out via any of the following:

* **Email:** [support@ifalabs.com](mailto:support@ifalabs.com)
* **Telegram:** [t.me/ifalabs](https://t.me/ifalabs)
* **GitHub:** [IFA-Labs/oracle\_contract/issues](https://github.com/IFA-Labs/oracle_contract/issues)

Include the token contract address, backing proof, and the protocol or use case driving the request. New feeds are reviewed and deployed on a rolling basis.
