ARCx Review 2026: Credit-Score Lending on ETH Collateral

ARCx is a decentralized scoring protocol that issues an on-chain DeFi Credit Score, described as the first part of a wider DeFi Passport for on-chain identity. Its lending product, ARCx Credit, is a credit market that the docs place on Polygon. It offers ETH-collateralized loans with a maximum loan-to-value ratio that depends on the borrower's score.

The problem it targets is that most DeFi lenders give every borrower the same terms regardless of track record. ARCx argues that a reputation layer could let careful borrowers take more debt against the same collateral and let lenders price risk by borrower.

The protocol is tracked on Ethereum and has its own governance token, ARCx. The documentation pages are dated 2022, and the token's listed market volume is currently zero. Treat it as a niche, possibly dormant project and verify its status before using it. DeFi trackers file it under insurance, but the docs describe a credit and lending product.

ARCx calculates a credit risk score for each wallet address from historical on-chain borrowing activity. The scores are published on-chain through an oracle, and the app fetches them from an API and verifies them against that oracle.

Borrowers deposit ETH as collateral in ARCx Credit vaults. The protocol offers each borrower a personal maximum LTV based on their score. A higher score means more debt against the same collateral. The aim is to reward reliable borrowers with better capital efficiency, which a plain pool treats the same as everyone else.

Scores come from three rules. A daily reward looks at your borrow usage over 120 days and pays most near 60% usage. A survival reward looks at how well the wallet avoids liquidations on third-party platforms over its lifetime. A liquidation penalty removes points for each day a liquidation occurs, for 120 days. The team controls the reward curve and growth speed.

Borrowing rates, protocol fees and any score-related charges are not given in the material reviewed. The docs have separate Borrowing and Supplying pages, which is where users would look for current terms. Polygon or Ethereum network gas costs would apply on top of any protocol fees.

The docs say the team manages control parameters to refine its risk exposure and profit model over time. That suggests terms can change, so check the app before borrowing.

No audits are listed for ARCx in the tracking data, and the docs excerpt reviewed does not name an auditor. Check the Risk management and Contracts pages for current audit and contract information. Team identities and any bug bounty are not stated in the material reviewed.

Users face smart-contract risk, oracle and API risk, and liquidation risk on ETH collateral. Because the team manages score parameters and control settings, rule changes are possible. The docs are dated 2022 and token listings show zero 24-hour trading volume, so users should confirm the protocol is still operating before depositing funds. Nothing points to a hack or shutdown.

ARCx is for DeFi users and builders interested in on-chain reputation and credit scoring. It suits borrowers who already hold ETH and would accept a collateralized loan to build a score. Anyone wanting audited, high-liquidity lending with published fees will need to check carefully first.
