Description

😀 What is Batua...? Batua (बटुआ) is an end-to-end "concept" for cryptocurrency in India. 🇮🇳 The word Batua is the phonetic spelling of the word for "wallet" in the Hindi language. 👛 Users of Batua transact entirely in Rupaysa, a decentralised non-custodial stablecoin pegged to the Indian Rupee. ⛓️ The project's key objective was to clearly demonstrate what is technically possible today, combining... - well-understood crypto primitives 📜, - an emerging Layer 2 solution 📈, - some bespoke development 🔢. ...to make a robust and usable wallet, ready for adoption. 👨‍👩‍👧‍👦 The solution comprises: - a decentrally-governed and non-custodial mechanism for a stablecoin, pegged to the Indian Rupee, based on MakerDAO SCD, using a Chainlink Oracle populated from CryptoCompare. ⚖️ - a minimalist web-wallet user-interface for sending and receiving Rupaysa, using Biconomy's gasless meta-transactions to pay fees on Matic L2, for a simplified user experience. 😺 The result is a concept to help introduce users to crypto, for making everyday payments in India. 📅 🧐 Why Batua...? India is an incredibly diverse country... but it is united in its use of the Indian Rupee. 🇮🇳 Digital payments for everyday spending are already common, where users scan QR codes with their smartphones, and pay using real money. 🤳 With a population of 1.3bn, and ~700m smartphones, it may be reasonable to expect Batua to find product-market fit in India. 🥳
