The Decentralized
Credit Bureau
for Web3
Privacy-preserving reputation scores for DeFi lending, governance, and compliance. Prove your creditworthiness without revealing your history.
Indexing activity from leading protocols
DeFi has a trust problem
Over-collateralization locks up $50B+ because protocols can't assess borrower risk. Every wallet looks the same — whether it's a whale with 5 years of perfect repayment history or a fresh address created yesterday.
Traditional credit scores require surrendering your privacy. CrowdProof changes this. We analyze on-chain behavior across multiple protocols and chains to generate a reputation score — then let you prove it with zero-knowledge proofs.
Score Verified
DeFi Lending: 785 — Confidence: 88%
Everything you need for on-chain trust
A complete reputation infrastructure — from raw blockchain data to verifiable ZK proofs, all accessible via a simple API.
Privacy-Preserving
Zero-knowledge proofs let you prove your score without revealing the underlying data. Your financial history stays yours.
Multi-Chain
Aggregates activity across Ethereum, Polygon, Arbitrum, Base, and Optimism into a single unified reputation.
ML-Powered Scoring
LightGBM models trained on real lending data. Not just transaction counts — we analyze borrowing behavior, governance participation, and more.
8 Score Categories
Overall, DeFi Lending, Governance, Social, Trading, NFT, Developer, and Cannabis Compliance. Each with independent confidence levels.
On-Chain Verification
Scores are committed to an on-chain oracle. Any smart contract can query reputation with a single function call.
Compliance Ready
Purpose-built cannabis compliance module with state-by-state rules, Metrc integration, and ZK age verification.
How it works
Connect Your Wallet
Sign in with Ethereum (SIWE). No email, no password. Your wallet is your identity.
Get Your Score
We index your on-chain activity across 5 chains and 6+ protocols. ML models generate scores in 8 categories.
Prove Without Revealing
Generate a ZK proof that you meet a threshold (e.g., score > 700) without exposing the actual number.
Cannabis compliance, reimagined
Dispensaries spend hours verifying IDs and filing compliance reports. CrowdProof replaces ID scanning with ZK age proofs — verify once, prove forever. No PII stored, ever.
- ✓24 states supported with automatic rule updates
- ✓Metrc & BioTrack integration for seed-to-sale tracking
- ✓ZK age verification — no ID needed after first visit
- ✓Automated compliance reporting and scoring
Build with 3 lines of code
SDKs for every major language. Query scores, generate proofs, and verify identities — in your stack.
import { DecentraID } from '@decentra-id/sdk';
const did = new DecentraID({ apiKey: 'did_live_...' });
const score = await did.reputation.getScore(
'0x1234...abcd',
'DEFI_LENDING'
);
// → { score: 785, confidence: 88, tier: 'High' }Simple, transparent pricing
