Mizan

Problem Statement

Mizan is a crypto-powered credit platform that makes it possible to offer zero-interest and uncollateralised credit without banks, overcollateralisation, or reliance on speculative crypto lending.We started with MizanPay, our first product: a Buy Now, Pay Later (BNPL) system that lets people pay over time using stablecoins while merchants receive instant payouts. Unlike traditional BNPLs that charge high fees or DeFi loans that require excess collateral and carry liquidation risk, MizanPay uses a flexible credit scoring engine that combines onchain wallet activity with optional KYC data.But Mizan isn’t just BNPL. It’s a credit infrastructure protocol that turns idle DeFi capital into real-world liquidity by allocating it toward purchases, not speculation. Our long-term goal is to offer credit rails for any kind of transaction—BNPL, recurring subscriptions, tokenized invoices, and more—while giving liquidity providers a sustainable way to earn yield backed by real-world spending.Our alpha build includes:A working BNPL checkout flow using stablecoinsCredit decision engine that integrates onchain wallet scoringLP simulation dashboard showing revenue and credit allocationA “Pay via Link” feature that enables merchants or sellers to request payments with built-in creditSDK prototype for merchants to easily integrate MizanPay into any online store or platformMizan brings credit access to underserved crypto users, opens new revenue streams for DeFi LPs, and empowers merchants to increase sales without risk.
