CAP Integrates Chainlink Price Feeds to Help Power cUSD

Apr 17, 2025

We’re excited to announce that Cap—a decentralized stablecoin protocol for covered yield at scale—has integrated Chainlink Price Feeds on Ethereum mainnet. By integrating the Chainlink standard, Cap has access to high-quality, tamper-proof price feeds needed to accurately price ETH and stETH-based restaking delegations that secure operator activity, supporting the minting and solvency of cUSD. This will provide our users with stronger assurances that cUSD minting and delegation mechanisms operate securely under volatile market conditions.

Our initial integration involves the use of the ETH/USD Chainlink Price Feed. We chose Chainlink as our preferred oracle solution because its infrastructure is seamless to integrate and time-tested in production. As the most widely adopted price data standard in Web3, Chainlink already helps secure leading DeFi protocols responsible for tens of billions of dollars in smart contract value, maintaining robust security and high availability even amidst unexpected events, such as exchange downtime, flash crashes, and data manipulation attacks via flash loans.

Cap is a decentralized, interest-bearing stablecoin protocol that enables institutions and onchain actors alike to mint cUSD with USDT & USDC. Cap allows whitelisted institutional operators to borrow cUSD’s underlying collateral and perform yield strategies, secured by ETH and stETH delegations from restakers.

In order to help secure our cUSD minting mechanism, we needed access to fresh asset prices that are supplied directly onchain in a highly reliable manner. Fair market asset prices should reflect a volume-weighted average from all trading environments. Thus, we needed to make use of an oracle network to fetch aggregated price data offchain and deliver it onchain to be consumed by our application.

“Chainlink Price Feeds provide the secure and reliable data backbone Cap needs to support institutional-grade stablecoin infrastructure. Through the use of the Chainlink standard, we will help advance institutional adoption of blockchain technologies.”— Benjamin.lens, Founder of Cap

About Cap

Cap is a stablecoin engine for covered yield. It leverages a collective of operators with specialized skills in yield generation to democratize yield previously untapped by the masses. This yield does not solely rely on crypto-native sources like funding rate arbitrage and token farming, but also on the expertise of traditional institutions like HFT firms, private credit funds, and other companies able to capture large-scale yield. Thanks to shared security markets, Cap is able to cover the risk of operator activity via cryptocurrency restaking. Restakers receive a premium for this coverage. Learn more by visiting cap.app.

Type III Stablecoins

Benjamin and Jae from Cap Labs Thanks to Carson, Ekram and Ishaan for their thoughtful feedback on this piece. With more than $200B in circulating supply, stablecoins have undoubtedly become the most significant sector within crypto today. One could even argue that the stablecoin sector has decoupled itself from the volatile crypto market—stablecoins have proved resiliency despite the crypto market's downturn in 2025, with more TradFi institutions actively integrating DeFi into their solutions

What is CAP: A Gentle Introduction to cUSD

The online platform economy has enabled small startups to scale to large tech giants, based on one counterintuitive dynamic: they do not own any of the inventory that makes up their networks. The most classic examples are Uber, which does not own any of the vehicles in its fleet, and Airbnb, which does not own any of the rooms that dot the platform. Using the power of the market, these companies are able to match those offerings with those in need of a service, whether it be a ride downtown or a

Productivity-Based Incentives on EigenLayer

X: @jaeyongp1, @Benjamin918_ Thanks to @ishaan0x and EigenLayer members for their review and discussions. TL;DR: A new mental model to understand EigenLayer is to view it as a productivity-based incentives platform where operators can take a more active role, building on the following assumptions: 1. An Actively Validated Service (AVS) on EigenLayer is not inherently a validation network. 2. As such, operators are not bound to perform validation tasks and can instead complete individual tas
