Rewards have always been at the heart of the Usual ecosystem, ensuring that users who engage with USD0++, provide liquidity, or participate in key DeFi platforms receive yield in $USUAL.

Now, we’re taking it a step further. Thanks to our collaboration with Brevis, the Continuous Protocol Incentivization (CPI) system enables trustless, verifiable, and secured rewards with Zero-Knowledge Proofs (ZKPs), bringing unmatched transparency and security to distribution.

With CPI, users can now independently verify their rewards on-chain and claim them: just pure DeFi.

What is Continuous Protocol Incentivization (CPI)?

CPI is a decentralized, on-chain rewards system designed to ensure fair, transparent, and scalable token distribution. Instead of relying on opaque calculations, Brevis’ ZK Coprocessor allows users to verify their on-chain contributions and claim their rewards with ZK Proofs ensuring accuracy.

Key Benefits of CPI:

• Fully Transparent: Rewards logic is open and verifiable—no hidden rules.

• Secure & Trustless: ZK Proofs eliminate the need for trust in a central party.

• Scalable & Efficient: Parallel off-chain computation significantly reduces costs and latency.

• Aligns Long-Term Growth: Rewards are distributed based on continuous engagement with the Usual ecosystem.

• Full Composability: Users continue receiving USUAL distributions even when going through complex looping strategies.

By leveraging ZK Proofs and decentralized computation, CPI ensures that rewards are accurate, fair, and seamlessly distributed to active contributors, without compromising on security or scalability.

How to Earn and Claim Rewards

The way you earn and claim $USUAL rewards remains unchanged: you still accumulate rewards daily and claim them via the Usual dApp in a single transaction.

Every day, Brevis fetches position data from integrated platforms, calculates the exact reward amounts, and generates cryptographic ZK Proofs that attest to the accuracy of the calculations. The proofs are then verified on-chain, ensuring that only eligible users receive their rightful rewards.

The result? Same seamless claiming experience, but now fully secured, trustless, and publicly verifiable.

How Positions Are Tracked and Rewarded

CPI ensures that every eligible position across the Usual ecosystem is accurately tracked and rewarded. Whether you’re holding USD0++, providing liquidity, or participating in lending markets, your contributions are recognized and rewarded daily.

Here’s a breakdown of how each position is tracked and rewarded under the upgraded system:

Daily Rewards Distribution to Usual USD0++ Holders

Rewards are distributed daily based on USD0++ balances on Ethereum and Arbitrum. If USD0++ is transferred, the new holder will receive the corresponding rewards.

Daily Rewards Distribution to Curve LPs

Users providing liquidity to USD0/USD0++ and USD0/USDC pools on Curve (Ethereum) receive rewards based on their LP token holdings. Transferred LP tokens inherit future rewards.

Daily Rewards Distribution to Pendle LPs and YT Holders 

LP and YT holders for USD0++ on Pendle (Ethereum) earn rewards daily. LP/YT token transfers ensure the new holder continues receiving incentives.

Daily Rewards Distribution to Morpho Depositors

Users supplying USD0++ as collateral (and optionally borrowing USDC) on Morpho (Ethereum) accumulate rewards. If liquidation occurs, the liquidator receives both the collateral and its associated future rewards.

Daily Rewards Distribution to Origami LPs

Usual will distribute daily rewards to LPs who deposit USD0++ into the Origami vault (i.e., holders of lov-USD0++ tokens) based on their position holdings on Ethereum mainnet.

Daily Rewards Distribution to Level Depositors

Users backing lvlUSD with USD0++ on Level (Ethereum) earn daily rewards proportional to their deposits.

Daily Rewards Distribution to Penpie Depositors

Users depositing Pendle USD0++ LP tokens into Penpie (Ethereum) receive rewards based on the USD0++ portion of their LP token. Penpie LP receipt tokens ensure future rewards transfer upon resale.

Daily Rewards Distribution to Equilibria Depositors

Users depositing Pendle USD0++ LP tokens into the Equilibria PendleBooster contract (Ethereum) earn rewards based on the receipt token. Like Penpie, receipt tokens ensure future rewards transfer if the stake is sold.

Why CPI is a Game-Changer for DeFi Rewards

By integrating Brevis ZK Coprocessor, Usual ensures that rewards distribution is not just decentralized, but provably fair, scalable, and efficient.

This enhanced incentive structure strengthens the Usual ecosystem by:

• Removing opacity: Users can independently verify rewards.

• Reducing reliance on intermediaries.

• Enhancing scalability: Efficient off-chain computations reduce costs and latency.

• Rewarding real, sustained engagement: Ensuring $USUAL is fairly distributed to active participants.

With CPI now live on mainnet, Usual has taken a major leap toward a fully transparent, decentralized incentive model. This is just the beginning: we plan to expand CPI to even more DeFi integrations and refine the system for maximum efficiency.
