Cardstack will use Chainlink Price Feeds to establish accurate and tamper-proof exchange rates on the platform. Exchange rates are extremely important in payment use cases, as they ensure that customers and merchants are able to find a path from the token the customer holds to the currencies the merchant accepts. The Chainlink oracle network provides many types of exchange rates—from native tokens like ETH to stablecoins like DAI and fiat currencies like USD, as well as emerging community and governance tokens. Used in conjunction with decentralized exchanges like Uniswap, Chainlink enables Cardstack to provide seamless one-click payments from the customer’s wallet. The latest Chainlink price feed update will be used to calculate the right amount of tokens to transfer from the customer to the merchant, without requiring a separate step to swap before the payment can be processed.

By going beyond data delivery and providing secure off-chain computation, Chainlink oracle networks enable hybrid smart contracts that benefit from the deterministic transparency of on-chain logic and the high-throughput efficiency of off-chain services.

Decentralized Oracle Networks (DONs) and Blockchains have distinctly different but very complementary goals. Blockchains create immutable on-chain state and computations, while oracle networks provide them with key off-chain inputs, without creating a blockchain.

Join us on Chainlink Live for a video Q&A with Upshot. We cover how Upshot uses a decentralized crowdsourcing method to determine fair prices for NFTs, the role of appraisal in digital art and collectibles, and how Upshot is using Chainlink VRF to ensure fair appraisal valuations.

VRF in NFT Appraisals

Upshot will use Chainlink’s VRF to randomly select committees of appraisers who will have their appraisals considered when pricing NFTs. This use of Chainlink’s VRF both increases the cost of manipulating NFT appraisals and makes the system more efficient by only requiring a small, fixed number of appraisers’ responses to be considered and/or scored.

"I am amazed by what Chainlink has already been used to create and am deeply grateful to all the people working on it. Thank you for all the various support, long nights, and hard work. We are all building the smart contract industry into something truly world-changing, together."
Sergey Nazarov, Co-founder of Chainlink

In this Chainlink User Roundtable, technical leads from Aave, Polygon, Instadapp, and Gelato discuss a recent debt financing bridge that automates moving a debt position from Aave on Ethereum L1 to Polygon L2. This allows Aave users to keep their debt positions and migrate the debt to Polygon's high-throughput L2 Ethereum sidechain.

The discussants cover the implications for DeFi as more solutions leverage composability between scaling platforms and layer one. Namely, how smart contract automation and dApps with high transaction volume will take advantage of scaling and find homes on layer two, and how scaling enables greater developer innovation.

Speakers:
-Marc Zeller from Aave
-Luis Schliesske from Gelato
-Samyak Jain from Instadapp
-Pranav Maheshwari from Polygon

Host: Andy Boyan from Chainlink Labs
