Opus Review 2026: Autonomous Credit on Starknet

Opus is a cross-margin autonomous credit protocol on Starknet. It lets users borrow against a portfolio of curated collateral, including yield-bearing assets, and sets interest rates, maximum loan-to-value ratios and liquidation thresholds dynamically for each user.

The pitch is a credit system with minimal human intervention and no fixed parameters. Savers can deposit the synthetic asset and earn interest from borrowers, while credit users can gain leverage on yield-bearing collateral.

DefiLlama lists Opus under CDPs, with about $334,000 in TVL, two listed audits and a listing date of August 2024. It has no token on DefiLlama, though the homepage introduces an $opus token. Some homepage copy carries 2022 and 2023 dates.

Opus is a collateralized debt protocol. A user deposits assets, including yield-bearing ones, and borrows a synthetic asset against them. The homepage describes the synthetic as a tokenized representation of the user's portfolio and the yield it generates.

Instead of fixed rates, the protocol uses an Adaptive Controller. A base rate depends on the collateral mix, and a multiplier moves with the gap between the synthetic's peg target and its market price. When the synthetic trades off peg, borrowing becomes cheaper or costlier to push it back.

If a position becomes undercollateralized, a multilayer liquidation engine steps in. The homepage lists a Stability Pool, MEV searchers and Dutch auctions. Savings users deposit the synthetic and earn interest paid by borrowers.

Opus says on its homepage that there are no high fees, but it does not publish a fee table. The main cost is the borrow interest rate, which combines a collateral-based base rate with a controller-set multiplier and changes over time.

Current rates, any origination or other charges, and Starknet network fees would be visible in the app and the docs before a transaction. Check them live, as nothing here is fixed.

DefiLlama lists two audits for Opus, and the homepage says it is audited and formally verified. The auditors are not named, so check the docs for reports. Audits reduce but do not remove smart-contract risk.

Risks include liquidation if collateral falls, the synthetic losing its peg, and reliance on an autonomous controller and liquidation actors working as intended. The docs list a Risks page, a Recovery Mode and Global Settlement. Small TVL means thinner liquidity. No incidents are mentioned publicly, and no regulatory status is stated.

Opus is for DeFi users already on Starknet who want to borrow against a diversified portfolio or earn savings yield from borrower interest. It suits readers comfortable with liquidation risk, variable rates and synthetic assets, and is a poor fit for anyone wanting fixed terms or deep liquidity.
