Hopper
WhatsApp + Your bank = Instant .eth payments -- We leverage Pix in Brazil to allow instant and free on-ramp
Project Description
Hopper allows users to make crypto payments from fiat using Whatsapp.
The amazing thing about this solution is that WhatsApp and Pix (fiat rails) have incredibly deep penetration in Brazil (~98.5% of working population) and are part of the daily routine of most people.
In practice this unlocks the ability for businesses (in or out Brazil) to accept crypto payments from any Brazilian person.
How it's Made
The tech stack is composed of:
- WhatsApp business API
- ChatGPT API
- Biconomy for smart accounts
- Stablecoin on-ramp via brla.digital on Polygon
- Li.Fi for swaps
- ENS for human readable addresses
The way it works, is when the user shows the intent to do a payment, the AI agent (ChatGPT) converts that into a swap. It understands the ENS, transforms the ticker into an address, gets the decimals, and build the corresponding transaction.
It will always start on a BRL on-ramp using BRLA, which is done via instant and free payments on the Brazilian Pix payment network and immediatly connect that to the swap to the .eth address.
