Reactive x DIA: Bringing Price Feeds to Reactive Network

Reactive Network

Mar 2, 2026 — 2 min read

DIA price oracles will be integrated with Reactive Network on March 2, 2026. The integration introduces an on-chain price feed for REACT/USD, available on Base Mainnet and accessible to Reactive Contracts and other smart contracts.

This integration provides a publicly accessible price reference for REACT that can be used by automated on-chain applications.

On-Chain Price Data

Blockchains can’t directly access external data such as market prices. Oracles provide this information on-chain. In this case, the oracle publishes the price of REACT in USD so that smart contracts can use it as an input for automated logic.

For example, a smart contract may:

trigger an action when REACT reaches a target price
compare REACT prices across chains
track price movements over time
use REACT price data in DeFi applications

DIA Oracle Architecture

The DIA system collects price data from centralized and decentralized exchanges. These trade prices are processed and combined into a single value. The final price is written on-chain where it can be read by smart contracts.

The process consists of several steps:

Sources – Market data is collected from exchanges where REACT is traded.
Feeders – Nodes submit price data to the DIA network.
Aggregation – Submitted prices are combined using a median calculation.
On-chain update – The resulting price is stored in an oracle contract.

The oracle updates when the price moves by more than 1%, or at least once every 24 hours.

Price Feed Details

Network: Base Mainnet

Oracle Contract: `0x5612599CF48032d7428399d5Fcb99eDcc75c06A7`

Feed: REACT/USD

The oracle provides:

REACT price in USD
Timestamp of the last update

This information is stored on-chain and can be accessed by any application.

With the DIA integration, price data becomes one of the conditions Reactive Contracts (RCs) can monitor. This allows RCs to react to price movements without relying on external bots or manual input. Typical uses include:

price-triggered actions
automated portfolio logic
liquidation monitoring
cross-chain automation

About Reactive Network

Reactive Network is an EVM automation layer built around Reactive Contracts, event-driven smart contracts for cross-chain, on-chain automation.

Reactive Contracts monitor event logs across EVM chains and execute Solidity logic when subscribed events occur, autonomously deciding when to send cross-chain callback transactions. This model supports conditional cross-chain state changes and continuous cross-chain workflows.

Build once — react everywhere!

Liquidation Protection: Building Continuity Into DeFi Lending

For many users, liquidation doesn’t feel like a design flaw. It feels like a shock. A position rarely collapses out of nowhere. It weakens first. Health factor drops. Buffers thin out. Prices move against you. Then one transaction closes everything. That disconnect or sudden enforcement is what soft liquidation

Liquidation Protection: Designing Around the MEV Funnel

The first phase of DeFi lending broke under speed: systems that assumed human attention and reaction time were overtaken by markets that moved faster than users could respond. The second broke under incentives: liquidation began rewarding those who could trigger and capture it, not those who reduced risk. As liquidation

Liquidation Protection: Correcting DeFi’s Cliff Edge

DeFi promised a financial system that runs on code rather than intermediaries. Anyone could lend, borrow, and build positions without permission. That openness opened the door to rapid experimentation, but it also surfaced a risk that traditional finance hides behind desks and phone calls: liquidation. Liquidation isn’t a flaw.

Prediction Markets: From Signal to Action

By the time prediction markets moved on-chain, belief had become legible. Trust was minimized. Participation was permissionless. Prices updated continuously. Signals could be read by anyone, at any moment. But legibility is not agency. Markets could tell us what people believed while it still mattered, yet nothing on-chain responded to
