Chainlink can be stored anywhere ERC20’s can, even though. It doesn’t have its own blockchain and never will, so you don’t need to worry about a token swap. Chainlink is actively securing value on a number of DeFi platforms via their Feeds. provides a bit more context. Social encountersThis live-stream Q&A features Anthony Sassano of Set Protocol and Johann Eid of Chainlink. They will be discussing the Chainlink integration, Set Protocol as a native DeFi primitive, and what the Set Protocol team is looking to create in the future. Set Protocol is a non-custodial protocol built on Ethereum that allows for the creation, management, and trading of Sets, ERC20 tokens that represent a portfolio or basket of underlying assets. Each Set operates and periodically rebalances its portfolio according to a strategy coded into its smart contract.

The team have redeployed the ETH-USD contract on Ethereum to provide smart contract developers more options and flexibility for gathering data from their Price Reference Contract. Chainlink’s ETH/USD price feed is currently secured by an aggregation of 21 independent, security reviewed, and Sybil Resistant node operators, many of which are run by leading blockchain DevOps and security teams. Each node sources data from high-quality data aggregators such as BraveNewCoin, with at least seven different Aggregators used on the ETH/USD Reference Contract. This architecture ensures that Chainlink’s ETH/USD oracle consistently provides highly accurate and on-time data using a decentralized aggregation of independent nodes and data sources. The DeFi ecosystem now has access to the largest collection of on-chain market data in the entire existence of building open financial products on Ethereum. Use the new to explore and gain access to this growing list of cryptocurrency, fiat currency, and commodity prices available on-chain and secured by Chainlink’s decentralized oracle networks. Collectively, these decentralized oracle networks secure over 100M USD in value for a variety of leading DeFi products across numerous financial markets, such as , , , , and more. Chainlink’s Price Reference Data oracle networks vastly expand the amount of secure and reliable data accessible to Ethereum Dapps, greatly accelerating the rate at which new DeFi products can be successfully launched. Chainlink Decentralized Oracle Networks for Price Reference Data are a shared community resource supported by its users, who pay less for using these oracle networks than it would take for them to broadcast the same data individually, while benefiting from a significant increase in the security created by the decentralization of oracle networks. DeFi requires constant access to real-time market data, especially prices, to reliably execute the logic underpinning applications. For instance, money (), derivatives (), lending (), and decentralized exchange () protocols are all examples of applications that need to quickly know the price of certain assets before performing a core on-chain function. Even if the contract logic is composed of high-quality code, the outputs of the smart contract are fully dependent on the quality of the inputs received. This means that securing accurate market data is as crucial to the security of decentralized finance as the underlying smart contract itself. While a few Dapps can operate solely using on-chain data, conservatively, 90+% of DeFi applications need a steady connection to off-chain data to function in a trusted, robust, and economically sustainable manner. Most price discovery happens outside of blockchain networks (off-chain), such as on major exchanges, and prices vary across these platforms. As a result, obtaining the most reliable price for an asset requires aggregation from multiple off-chain data sources. Chainlink’s decentralized oracle networks are composed of security-reviewed, Sybil-resistant, and fully independent nodes. These nodes are run by leading blockchain DevOps and security teams, many of which have extensive experience running POS nodes that secure millions of dollars in value across multiple blockchain networks. Every time there is a request for an on-chain price update, each node in the network is tasked with retrieving and submitting the current price. The responses are then aggregated together off-chain and pushed on-chain as a single price update. Incorporating decentralization at the node level ensures high availability for all Chainlink-powered price reference data oracle networks. They also maintain data quality via redundancy, by having each node retrieve the price from an API such as , , etc., which aggregates data from many sources. Currently, there are seven data aggregators being used on most networks. Thus, the on-chain price update is a cumulative aggregation of individual nodes that retrieved the price from a trusted data aggregator. This ensures that DeFi applications constantly interact with high-quality market data. Supporting projects can call these reference contracts to access up-to-date price feeds that trigger the execution of core product functions. The on-chain updates can be programmed to occur based on time (hourly, daily, etc.), price deviation (such as every 1% change in price), or a customized combination adapted to the specific user’s needs. RoadmapThe team does not publish a roadmap but you can follow progress on and Partnerships and team membersMCDEX are thrilled to announce that they are using i as the index price for the ETH-PERP contract. MCDEX is a decentralized derivatives exchange that provides top service and experiences. By introducing AMM, MCDEX has become the first project has enabled decentralized perpetual contracts with transparency and unparalleled experiences. MCDEX has closely monitored DeFi’s changing dynamics and identified a large market demand for improved infrastructure in decentralized derivatives. To fill this critical market need, MCDEX set out to build DeFi’s best derivatives trading platform by developing decentralized Perpetual Contracts. MCDEX’s , ETH-PERP, was recently launched live on the Ethereum mainnet with the following features: By running an on-chain AMM and off-chain order book, the Perpetual Contract has two trading pages. Users can trade with the AMM, which is fully decentralized, simple, and intuitive; or trade with the Order book, which is similar to Perpetual Contracts on centralized exchanges. Importantly, by sourcing data from numerous different aggregators, MCDEX gets far better market coverage for its index prices than centralized derivatives platforms, which either don’t disclose their data sources or only use a few exchanges. Not only will the ETH/USD index price reflect the price discovery happening throughout the entire market, but it will better follow rapid volume shifts as they occur across exchanges. With Chainlink having already launched on mainnet, MCDEX can leverage these reference contracts in the future and/or create custom ones to quickly launch Perpetual Contracts for new assets. Thus, MCDEX can expand its product offerings at an accelerated pace while still ensuring the highest security standards and accuracy of MCDEX’s index prices.

ParaSwap provides its users with the best prices.Paraswap’s integrated 15 different liquidity providers since inception. Recently the ParaSwap team have shifted some of their focus towards improving Paraswap’s oracle mechanism. As a DEX aggregator, Paraswap needs to fetch & aggregate the liquidity from all relevant DEXs for a particular trading pair. The best swapping path depends only on the assets themselves. ParaSwap picks the one that returns more of the target assets regardless of its fiat price. Paraswap used to get its prices for ETH and ERC20 tokens directly from APIs, such as CoinGecko and CoinMarketCap. The main benefits of the collaboration: Speed Chainlink’s Price Reference Contracts store prices on-chain for most major ETH and ERC-20 trading pairs. As such, Paraswap’s systems can easily and cheaply read these on-chain prices and use them as the base price for determining which liquidity pools offer the best rates at a given moment in time. Price Accuracy Chainlink’s Price Reference Contracts provide accurate market data sourced from a pool of high-quality data aggregators. While Paraswap was already using aggregators, Chainlink further extends their market coverage by having at least seven aggregators present on each Price Reference Contract. Security Chainlink’s Price Reference Contracts consist of decentralized oracle networks with 7–21 nodes each, which source data from at least seven different sources. Having decentralized aggregation at both the oracle and data levels provides enhanced security and reliability to the delivery and accuracy of Paraswap’s price feeds. Chainlink not only offers that most performant solution, but it’s also decentralized, further aligning Paraswap with the ethos of decentralization permeating throughout DeFi. Paraswap monthly transaction volume skyrocketed since the beginning of the year(Source: ) Having an on-chain price feed will become more and more useful, especially for complex DeFi tokens such as options positions. By integrating with Chainlink now, Paraswap is better set up to offer more advanced products in the future that require Chainlink’s Price Reference Contracts.
