Overview We’re excited to announce the successful conclusion of our audit by Zellic (auditors of Pyth, 1inch, LayerZero & more). This audit was conducted on a much improved codebase since the last major upgrade of Empiric: We’re excited to finally release changes that make Empiric much easier to use (improved interface…

If you‘re familiar with traditional web2 development you must be used to how easy it is to get a server response provided in a callback to the frontend, and you’d probably expect that we can do the same with our smart contracts — only to be disappointed… But thanks to…

In collaboration with CurveZero, a fixed-rate lending/borrowing protocol on StarkNet. TL;DR StarkNet ecosystem has opened the door to the next wave of innovation in DeFi, by providing an infrastructure for cheap, verifiable computation on-chain. Empiric Network, the native oracle on StarkNet, has been developing essential computational feeds for the DeFi ecosystem to mature. In collaboration with CurveZero and using our high-quality…

We are excited to welcome Gemini, one of the leading cryptocurrency exchanges, to the Empiric Network! With this partnership, Gemini will contribute their proprietary crypto market data and thereby support Empiric Network in accelerating innovation in DeFi. Gemini sends its signed and timestamped data directly on-chain to Empiric’s smart contracts…

In the next few weeks we’ll be open sourcing a few of the tools we’ve developed to ensure we are able to quickly and safely develop Cairo smart contracts. We hope they help you do the same! …

Compound and Coinbase were tired with the status quo of black box off-chain oracles on Ethereum so they collaborated to create the open oracle standard. …

Bringing Proprietary, High-Quality Data to StarkNet CMT Digital and Empiric Network are excited to announce their data partnership. CMT Digital contributes proprietary, high quality data from its trading and market making operations to Empiric Network. CMT signs and timestamps its data before sending it directly on-chain. From there, Empiric’s smart contracts verify the signature and aggregate…

First vs Third-Party Oracles Broadly, there are two types of oracles (entities that connect blockchains with the real world): First-party oracles enable data sources themselves to bring data on-chain, whereas third-party oracles work with aggregators and other middlemen. The majority of oracles today are third-party oracles that pull data from APIs and use a…

This guide will cover how to use a proxy to write upgradable contracts on StarkNet. The proxy pattern consists of the proxy contract and the (upgradable) implementation contract. We will discuss a hands-on example of OpenZeppelin’s proxy guidelines. Along the way you will gain some practice using starknet.py. You should…
