Voulti

Problem Statement

Voulti Payouts solves the broken system of cross-border payments from U.S. companies to Latin America.Today, platforms like Viagogo, Fiverr, and Upwork struggle to pay users in countries like Colombia, Mexico, or Brazil, facing long delays, high fees, and poor exchange rates.With Voulti, any business can pay a recipient instantly using PayPal USD (PYUSD). Recipients automatically receive their local stablecoin (like cCOP, MXNB, or BRLA) within seconds, even if they don’t have a wallet. They simply receive an email and can claim their funds securely.The goal is to make sending money as easy as sending an email: simple, fast, and global.PYUSD acts as the source of truth and settlement layer, while Voulti abstracts the blockchain complexity into a human experience.Voulti empowers companies to pay global contributors, sellers, and partners instantly and at a fraction of traditional costs, without requiring any crypto knowledge from the end user.
