First Digital USD (FDUSD) API and Price Oracle

The First Digital USD price API returns real-time FDUSD market price data aggregated from trades across multiple on-chain and off-chain exchanges. Developers integrate this endpoint into applications to display current FDUSD valuations, execute price-dependent logic in smart contracts, or feed data into trading algorithms and dashboards.

FDUSD is a stablecoin pegged to the US dollar, and price feeds for it serve applications across DeFi, trading platforms, and risk management systems. DIA provides a First Digital USD price API by aggregating individual trade data from 100+ exchanges covering 3,000+ assets including FDUSD.

A free API endpoint is available on this page for testing and evaluation. For production deployments or custom requirements, DIA builds dedicated feeds configurable by data sources, pricing methodology, and update frequency through DIA's Discord or Telegram.

DIA publishes a free First Digital USD price API endpoint on this asset page, available for developers to test and evaluate without cost. The free endpoint is designed for testing and evaluation purposes only, not for production use.

For production deployments or customized First Digital USD feeds, DIA builds dedicated price oracles configurable by data sources, pricing methodology, and update frequency. These production feeds are requested via DIA's Discord or Telegram channels, where developers can specify their requirements and integrate verified price data into their applications across supported blockchains.

A blockchain price oracle is an external information provider that supplies verified data from outside the blockchain to smart contracts, enabling them to access real-world market prices and other information on-chain.

DIA can deploy a First Digital USD (FDUSD) price oracle on any of its 60+ supported blockchains, delivering verified on-chain FDUSD price data that smart contracts can consume. DIA's oracle infrastructure runs on Lasernet, DIA's Ethereum layer-2 rollup, which makes each feed independently verifiable. This architecture ensures that FDUSD price feeds remain trustworthy and transparent across applications.

Custom price oracles are fully configurable by data sources, pricing methodology, and update frequency. Teams requiring production-grade feeds or tailored specifications can request a dedicated oracle via DIA's Discord or Telegram channels.

First Digital USD (FDUSD) price calculation aggregates individual trade data from on-chain and off-chain sources across multiple exchanges rather than relying on a single exchange or liquidity pool. DIA sources FDUSD trades from numerous venues and combines them using a transparent methodology to produce a single price feed.

The data sources and pricing methodology used in DIA's FDUSD feed are transparent and publicly documented. For production deployments, the feed itself is configurable: developers can request a dedicated feed tailored to specific data sources, pricing rules, and update frequency through DIA's Discord or Telegram channels. This approach allows applications integrating FDUSD price data to align the feed parameters with their own requirements and risk tolerance.

First Digital USD (FDUSD) is a stablecoin, so price feeds serve primarily to verify its peg and detect deviations from $1 USD. Developers building on-chain applications can consume FDUSD price data for several concrete purposes.

Lending protocols use FDUSD price feeds to calculate collateral ratios and trigger liquidations when borrowers' positions weaken relative to stablecoin reserves.
Decentralized exchanges and automated market makers monitor FDUSD price feeds to detect and correct arbitrage opportunities when the stablecoin trades away from parity.
Cross-chain bridge operators use price feeds to validate FDUSD peg health before processing transfers between blockchains, preventing users from depositing depeg'd tokens on destination chains.

Developers sourcing First Digital USD price data benefit from DIA's transparent aggregation across 100+ exchanges and on-chain sources. Since First Digital USD operates as a stablecoin across multiple blockchains, having configurable price feeds tailored to specific data sources and update frequencies reduces reliance on single-source price feeds and improves resilience for applications integrating FDUSD.

DIA's infrastructure supports deployment across 60+ blockchains, enabling consistent FDUSD pricing regardless of which chain an application operates on. Each feed remains independently verifiable through Lasernet, DIA's Ethereum layer-2 rollup, providing cryptographic proof of data integrity.

Developers can evaluate DIA's FDUSD pricing using the free API endpoint available on this page. For production requirements, custom feeds configured by source selection, methodology, and update cadence are available through DIA's Discord or Telegram channels.
