On-chain credit, for most of its short history, has meant one thing: lock up $150 of ether to borrow $100 of stablecoin. That arithmetic works for traders. It does not work for anyone who actually needs credit.
Fuero is trying to break that pattern. The company is building an undercollateralized credit line aimed at US prime borrowers, with funds delivered directly in crypto and underwriting tied to a borrower's traditional credit score [fuero.xyz]. The pitch: if you have the FICO of someone a bank would lend to unsecured, you should be able to draw a crypto-denominated line without posting 150% of it in volatile assets first.
The second piece is identity. Fuero says borrowers carry a privacy-preserving identity profile they own, rather than re-submitting documents to every protocol they touch [fuero.xyz]. The company frames it under a tagline of "Your Credit, Your Rights. On-Chain."
The bet
Fuero is led by CEO Alejandro Losa and CTO Paul Arbic, who were introduced publicly in a post by token-engineering firm Protofire describing the company's wedge as "undercollateralized credit lines for US prime borrowers that land directly in crypto and build a privacy-preserving identity profile you own".
The target customer matters. Prime borrowers are the segment traditional lenders fight hardest over. They are also the segment most underserved by existing DeFi credit, which has largely been built for the opposite profile: anonymous users with crypto collateral and no credit history to speak of.
Why it could matter
The undercollateralized lending category in crypto has been a graveyard of good intentions. Goldfinch, Maple, TrueFi and others have each taken a swing, mostly by routing capital to institutional borrowers or emerging-market funds. Consumer-facing undercollateralized credit, tied to a real-world credit bureau score, is a thinner field.
If Fuero can underwrite to FICO and enforce repayment well enough to keep loss rates inside a sustainable spread, the addressable pool is large. US revolving consumer credit sits north of $1 trillion. The privacy-preserving identity component, if it actually travels between protocols, could become the more durable asset over time.
The team and what is shipping
Losa and Arbic are positioning Fuero squarely inside the US regulatory perimeter. Underwriting American consumers against their credit score means engaging with the Fair Credit Reporting Act, state lending licenses, and the patchwork of consumer-protection rules that have tripped up earlier crypto-credit attempts.
The product, as described on the company's site, is live in concept: a credit line, denominated and delivered in crypto, drawn against a borrower's score, paired with an identity profile the borrower retains [fuero.xyz].
What bears say, what bulls answer
The credible bear case is straightforward. Undercollateralized consumer lending in crypto has a poor track record because there is no effective recourse: a borrower who defaults on a wallet-based loan can simply walk, and the lender's only lever is a credit-bureau report the borrower may not care about.
The bull answer, embedded in Fuero's design, is that prime borrowers are the wrong population to assume will walk. The entire premise of a 750-plus FICO is that the borrower has spent years protecting it and will continue to. If Fuero reports defaults to the bureaus the same way a bank does, the recourse is real.
What to watch
The next twelve months should answer three things. First, a disclosed funding round. Second, a published loss curve on the first cohort of borrowers. Third, whether the privacy-preserving identity layer gets adopted by any protocol outside Fuero itself.
