Decentralized USD (USDD) API and Price Oracle

The Decentralized USD price API is a data service that returns real-time price quotes for USDD, the stablecoin issued on the TRON blockchain. The API aggregates individual trade data from on-chain and off-chain sources across multiple exchanges to compute a single market price feed.

Developers integrate the price API into applications that need current USDD valuations for trading interfaces, portfolio trackers, lending protocols, or risk management systems. The API endpoint delivers structured price data that smart contracts or backend services can consume directly.

DIA offers a Decentralized USD price API with a free testing endpoint available on this page. For production deployments or custom requirements, DIA builds dedicated feeds configurable by data sources, pricing methodology, and update frequency. Requests can be submitted via DIA's Discord or Telegram channels.

DIA publishes a free Decentralized USD price API endpoint on this asset page, available for developers to test and evaluate at no cost. The free endpoint is designed for testing and evaluation purposes only, not for production deployment. Developers requiring production-grade feeds or custom configurations for Decentralized USD, such as alternative data sources, pricing methodologies, or update frequencies, can request a dedicated feed through DIA's Discord or Telegram channels. DIA aggregates individual trade data from 100+ exchanges to construct its price feeds across 3,000+ assets.

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

DIA can deploy a Decentralized USD price oracle on any supported chain to deliver on-chain USDD price data that smart contracts can consume. USDD is a decentralized stablecoin, and DIA's market price feeds aggregate individual trade data from on-chain and off-chain sources across 100+ exchanges to calculate accurate pricing.

DIA's oracle infrastructure runs on Lasernet, DIA's own Ethereum layer-2 rollup, which makes each feed independently verifiable. For production deployments or custom requirements, developers can request a dedicated price oracle configured by data sources, pricing methodology, and update frequency via DIA's Discord or Telegram.

DIA's Decentralized USD price is built by aggregating individual trade data for USDD from on-chain and off-chain sources across multiple exchanges. Rather than drawing from a single exchange or liquidity pool, this aggregation approach combines trades across numerous venues to form a composite price. The data sources and pricing methodology underlying the feed are transparent and documented. For production deployments, the methodology is configurable: projects can request a dedicated feed tailored to specific data sources, calculation rules, and update frequencies through DIA's Discord or Telegram channels. This architecture enables price feeds that reflect broader market conditions across USDD's trading venues instead of relying on isolated liquidity.

Decentralized USD (USDD) is a stablecoin issued on the TRON blockchain, pegged to the US dollar. Developers can consume USDD price feeds to build applications that depend on accurate USD valuations.

Lending protocols can use USDD price feeds to calculate collateral ratios and liquidation thresholds when USDD is deposited as collateral or borrowed. Decentralized exchanges and automated market makers require price feeds to maintain accurate swap rates and prevent arbitrage exploitation when USDD trades against other assets. Cross-chain bridge systems use USDD price data to verify peg stability during transfers between TRON and other blockchains, ensuring wrapped USDD representations remain properly valued on destination chains.

DIA aggregates Decentralized USD price data from over 100 exchanges across on-chain and off-chain sources, making the feed composition transparent and auditable. Developers can inspect exactly which sources feed into the price calculation.

For production use, DIA builds custom feeds configurable by data source selection, pricing methodology, and update frequency, tailored to each application's requirements. This flexibility is valuable for projects with specific liquidity or staleness constraints around Decentralized USD.

DIA deploys price oracles across 60+ blockchains, so Decentralized USD feeds reach the chains where the token is used. Each feed is independently verifiable through Lasernet, DIA's Ethereum layer-2 rollup, enabling smart contracts to validate oracle integrity directly.

Developers can test DIA's free price-feed API endpoint on this page. For production deployments or custom Decentralized USD configurations, contact DIA via Discord or Telegram.
