TopChain (TOPC) API and Price Oracle

The TopChain price API is a data service that returns real-time TOPC token prices calculated from aggregated trades across multiple exchanges and blockchain sources. Developers integrate this API into applications that need current market pricing for TopChain, such as trading dashboards, portfolio trackers, DeFi protocols, or automated market-making systems.

DIA provides a TopChain price API endpoint available on this page for testing and evaluation purposes. The free endpoint allows developers to assess data accuracy and latency before committing to production infrastructure.

For production deployments, DIA builds custom TopChain price feeds configurable by data sources, pricing methodology, and update frequency. Teams with specific requirements can request a dedicated feed through DIA's Discord or Telegram channels.

DIA publishes a free TopChain price API endpoint on this asset page for developers to test and evaluate without charge. The free endpoint is designed for testing and evaluation purposes only, not for production deployment.

For production use or custom TopChain feeds, developers should contact DIA via Discord or Telegram to request a dedicated feed. DIA can configure dedicated feeds by data sources, pricing methodology, and update frequency to match specific application requirements.

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

DIA can deploy a TopChain price oracle on any supported chain, delivering onchain TOPC price data that smart contracts can consume. DIA aggregates individual trade data from on-chain and offchain sources across 100+ exchanges to construct its price feeds. DIA's oracle infrastructure runs on Lasernet, DIA's own Ethereum layer-2 rollup, which makes each feed independently verifiable by design.

For production deployments or custom requirements, DIA builds dedicated price oracles configurable by data sources, pricing methodology, and update frequency. These are requested via DIA's Discord or Telegram channels.

TopChain price calculation aggregates individual trade data for TOPC from both on-chain and off-chain sources across multiple exchanges, rather than relying on a single exchange or liquidity pool. This approach draws from a broad dataset of transactions to compute the price feed.

The data sources and pricing methodology used in the feed are transparent. For production deployments, the methodology and update frequency are configurable to match specific requirements. Custom feeds can be tailored by selecting which sources to include, how to weight them, and how often prices update.

Requests for dedicated TopChain feeds can be submitted through DIA's Discord or Telegram channels.

TopChain (TOPC) is a layer-1 blockchain, so price feeds enable applications that depend on accurate valuation of the network's native asset for security and economic functions.

Developers can build staking reward calculators that reference real-time TOPC prices to show validators and delegators their returns in fiat terms. Decentralized exchanges on TopChain require accurate price feeds to prevent arbitrage manipulation during token swaps. Bridge protocols linking TopChain to other chains use TOPC pricing to calculate fair exchange rates for wrapped tokens and determine collateral adequacy when locking assets across networks.

DIA's price feed aggregates trade data from multiple sources, enabling these applications to access verifiable TOPC valuations without building their own data infrastructure.

DIA aggregates trade data from 100+ exchanges to construct price feeds covering 3,000+ assets, including TopChain. Developers can inspect exactly which sources and methodology feed into TopChain pricing, rather than relying on opaque aggregation. DIA deploys custom feeds across 60+ blockchains, configurable by data source selection, pricing logic, and update frequency to match TopChain's liquidity patterns and the requirements of consuming applications.

Each feed runs on Lasernet, DIA's Ethereum layer-2 rollup, enabling independent verification of TopChain price data on-chain. This architecture eliminates the need to trust a centralized oracle operator.

Developers can test DIA's TopChain pricing using the free API endpoint available on this page. For production deployments or custom configurations, teams submit requests through DIA's Discord or Telegram to specify data sources, methodology, and update cadence.
