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.

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.

Understanding Asset IDs

Asset IDs are fixed bytes32 identifiers generated by hashing the asset symbol using keccak256: 
bytes32 assetId = keccak256(abi.encodePacked("USDT/USD"));
This produces a deterministic, collision-resistant key used to query the oracle contract across all supported networks. The same asset ID works on Base Mainnet, Base Sepolia, and AssetChain — no remapping required. Best practice: Always store asset IDs as bytes32 constants in your contracts to avoid runtime computation and save gas. 
bytes32 public constant USDT_ASSET_ID = 0x6ca0cef6107263f3b09a51448617b659278cff744f0e702c24a2f88c91e65a0d;
bytes32 public constant CNGN_ASSET_ID = 0x83a18c73cf75a028a24b79cbedb3b8d8ba363b748a3210ddbcaa95eec3b87b3a;
bytes32 public constant ZARP_ASSET_ID = 0x12373a3b1c4827c84bf6d7b11df100442695d0abfdb7a20d30a41d67d58e75a8;

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: 
// 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 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: 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.
