API3 Brings First-Party Oracle Price Feeds to Arbitrum
What usually goes through your mind when a smart contract pulls in external data?
Most builders assume the price feed is “there,” but don’t always think about where that data actually comes from, who controls it, or how many trust assumptions sit in between. When something breaks, those details suddenly matter a lot.
That’s the gap
@Api3DAO is addressing and it’s now available directly on
@arbitrum.
Why Data Origin Matters More Than Ever
In DeFi, price feeds are foundational. Lending, perps, RWAs, & derivatives all depend on them. Yet many oracle systems still rely on layers of intermediaries, off-chain aggregation, or cross-chain bridges that introduce risk and opacity.
API3 takes a different approach. Instead of relying on third-party node operators, first-party oracle nodes are operated directly by the data providers themselves. This gives developers full on-chain verifiability over where the data originates.
You’re not trusting an abstraction. You’re consuming data from the source.
What API3 dAPIs Actually Are
dAPIs are API3’s decentralized price feeds powered by multiple first-party oracles. These oracles are run by the data providers, not middlemen, and their values are aggregated natively on the chain where they’re used.
On Arbitrum, this means smart contracts can now access decentralized price feeds that are:
✅ Maintained on-chain
✅ Operated by reputable data providers
✅ Aggregated without cross-chain bridges
All of this is delivered as a managed solution, so developers don’t need to run infrastructure or manage oracle updates themselves.
What “Managed” Really Means for Builders
With managed dAPIs, once a feed is deployed and activated, any smart contract in the ecosystem can read the value. There’s no per-project setup or custom integration required.
Developers simply reference the feed and consume the data. Maintenance, updates, & oracle operations are handled by API3 & the first-party providers.
This reduces complexity while improving security.
Who the Data Comes From
The feeds available on
@arbitrum pull data directly from well-known providers, including: dxFeed, Kaiko, Nodary, New Change FX, Coinpaprika, Finage, and Twelve Data.
That means onchain contracts are now consuming price data sourced and signed by the same entities that provide data to traditional finance and large crypto platforms.
Coverage & Feed Specifications
There are currently 120 feeds live across crypto, forex, commodities, & equities, with configurations such as:
🔹0.25% deviation with 2-minute heartbeat
🔹0.25% deviation with 24-hour heartbeat
🔹0.5% deviation with 24-hour heartbeat
🔹1% deviation with 24-hour heartbeat
This gives builders flexibility depending on how sensitive their application is to price movement & update frequency.
Why Native Aggregation on Arbitrum Matters
#dAPIs use native-chain aggregation, meaning data is aggregated directly on Arbitrum itself. There’s no need to rely on bridges to import oracle values from another network.
That design choice removes an entire class of risk and makes dAPIs particularly well-suited for applications that require strong security guarantees.
How Builders Can Get Started
Builders can browse and activate feeds through the API3 Market, where managed dAPIs are listed and maintained:
market.api3.org/dapis
For hands-on guidance, API3 also provides a developer getting-started video & full documentation covering integration & usage:
docs.api3.org
Support is available through the API3 Discord for teams that need technical help.
My View
As
#DeFi matures, oracle design is shifting from speed to provenance and trust minimization. API3’s first-party model fits that shift.
With dAPIs live on Arbitrum, builders get verifiable data without extra trust layers an upgrade not just in tooling, but in how onchain data is treated.
