TANGIBLE RESULTS
Business Outcomes for Your Protocol
Our DeFi Cross-Protocol Credit Passport service delivers measurable improvements in user acquisition, capital efficiency, and protocol security.
01
Expand Your Addressable Market
Unlock new user segments by allowing on-chain credit history from other protocols to be used as collateral in your DeFi application, increasing your Total Addressable Market (TAM).
50%+
Potential User Growth
New Segments
Access Uncollateralized Borrowers
02
Increase Capital Efficiency
Enable users to leverage their proven creditworthiness across chains, reducing over-collateralization requirements and freeing up capital for higher-yield opportunities within your ecosystem.
Up to 70%
Lower Collateral Ratios
Higher TVL
From Efficient Capital
03
Reduce User Acquisition Cost (CAC)
Attract high-intent, creditworthy users with lower onboarding friction. Pre-verified users from partner protocols translate to higher lifetime value (LTV) and lower marketing spend.
Lower CAC
Via Pre-Vetted Users
Higher LTV
From Creditworthy Users
04
Enhance Risk Management & Security
Integrate a standardized, audited credit scoring system. Our passport uses on-chain data and zero-knowledge proofs to verify history without exposing sensitive information, reducing your protocol's default risk.

PROVEN METHODOLOGY
Our Development & Integration Process
A structured, four-phase approach designed for technical founders to launch a secure, scalable DeFi Credit Passport with minimal operational overhead.
01
Discovery & Protocol Architecture
We conduct a deep technical analysis of your target DeFi ecosystem (Aave, Compound, Maker, etc.) to design a modular, upgradeable smart contract architecture. This phase defines the data schema, oracle integration points, and on-chain/off-chain logic split.

Frequently Asked Questions
Get clear answers on how our cross-protocol credit passport service works, from development to deployment and ongoing support.
A cross-protocol credit passport is a non-transferable, on-chain identity that aggregates a user's creditworthiness across multiple DeFi protocols. We build it using a combination of on-chain data oracles, zero-knowledge proofs (ZKPs), and a custom scoring algorithm. It creates a unified, portable reputation layer, allowing users to access undercollateralized loans and better rates on platforms like Aave, Compound, and MakerDAO without re-submitting credentials for each one.
