What is a Wallet?
A wallet is a digital tool that allows users to store and manage their private keys, granting full control over their digital assets like USDC. In the context of Qist, the wallet is where users hold their USDC tokens before and after participating in Islamic decentralized finance operations. Unlike centralized custodians, the wallet does not hold the user's funds; instead, it provides a secure interface to interact with smart contracts. The wallet itself does not provide financing or lending-it is a storage and signing medium for transactions.
What is a Platform?
A platform is a user interface that provides access to Islamic decentralized finance products. Qist is an Islamic decentralized finance platform built on Base, offering open-source smart contracts that adhere to Sharia principles such as asset ownership transfer and USDC payment. The platform facilitates lending and borrowing between users in a transparent manner, where assets move from the funder's wallet to the buyer's wallet via smart contracts, with a 2% fee. The platform does not hold funds but directs transactions through smart contracts.
What is an Exchange?
An exchange (or cryptocurrency exchange) is a platform that facilitates trading of digital assets, such as buying or selling USDC or Bitcoin. In the context of Qist, an exchange is used to provide initial liquidity; users can purchase USDC from an external exchange and then send it to their wallet for use on the Qist platform. An exchange differs from a platform in that an exchange enables swaps, while a platform facilitates Islamic finance based on sale and leasing. Qist does not act as an exchange but as an Islamic decentralized finance platform.
How Qist Applies This
In Qist, users need a wallet to interact with the platform: they transfer USDC from their wallet to the smart contract to purchase an asset (Murabaha or Ijara). The platform manages the process automatically, so users pay installments from their wallet and receive the asset after full payment. As for the exchange, it is not required within Qist; all users need is USDC in their wallet. Qist does not buy or sell USDC-it uses it as a payment currency. Under Sharia principles, the seller owns the asset, no riba or gharar, and surplus is returned to the buyer. This clarifies the essential difference among the three tools.
