Introducing Base

Base is an innovative, secure, and cost-effective Ethereum Layer 2 solution built by Coinbase. By offering an Ethereum Virtual Machine (EVM) environment at a fraction of the cost of Ethereum, Base enables developers to effortlessly onboard and secure user assets from ETH Mainnet and smoothly interoperate with other L2 chains.

Powered by the MIT-licensed, open-source OP Stack and developed in collaboration with Optimism, Base is building towards the vision of bringing the next billion users onchain.

“Reliable data is the lifeblood of the onchain ecosystem — without it, some of the most significant use cases such as NFTs or DeFi couldn’t exist. We’re super excited to collaborate with DIA to make high-quality price feeds available for devs building on Base mainnet, helping them stretch their imaginations and what they can build.” — Jesse Pollak, Base Lead

Providing DIA’s Data Library on Base

We are delighted to announce that DIA’s comprehensive data library is now available on Base mainnet. This deployment makes price feeds for over 3,000+ tokens, 18,000+ NFT collections, and more to become accessible to developers on Base.

Multi-Source, Customisable, and Transparent Oracle Architecture

DIA distinguishes itself in the Web3 data landscape with its transparent, customisable and cross-chain oracle infrastructure. DIA not only provides standard asset price feeds for blue-chip tokens but also allows the creation of fully custom, on-demand oracles for lesser-known tokens to address sophisticated use cases. To accommodate these needs, DIA fetches trade data directly from over 80+ onchain and offchain sources across 30+ L1/L2s and can swiftly integrate new exchanges on demand.

This granular data availability enables highly customisable token and NFT price feeds. All feeds are adjustable in terms of pricing methodologies, source markets and pair pools, oracle update mechanism, and frequency. Additionally, per demand, DIA also develops unique pricing methodologies and oracle logics for the special use cases.

This ensures that the data and oracle remain robust and resilient to the market conditions and provide a global market as well as specific individual or cross-chain market prices. DIA’s battle-tested oracle architecture already powers 100+ dApps, unlocking unique use cases across DeFi, NFTfi and GameFi verticals.

Base DIA Oracle Showcase

For developers looking to test DIA oracles, we have deployed a DIA demo oracle on the Base mainnet. Developers can interact with the following demo oracle smart contract:

Mainnet: 0xB8BF9ba432282F25F56e143641145349ab7c5Bf6
Testnet: 0x1BCBF8AbC9E2784e472548BE680d3f281F212A59

Note: DIA Demo Oracle contracts are not designed for live dApp integration. DIA assigns dedicated contracts for dApps, and we encourage you to request a dedicated oracle. Gain more insights on DIA demo oracles in the DIA documentation.
