## What it is
PicPay's public backend technical hiring challenge, a specification for building a simplified payments platform with user and merchant wallets, transfers, and unique CPF/email registration rules. It is not a working product but a challenge brief that candidates implement in any framework or language.

## Use cases
- practice building a payments transfer API
- prepare for a backend technical interview
- find a take-home coding challenge to sharpen backend skills
- build a simplified wallet system with users and merchants
- compare community solutions to the PicPay backend challenge
- learn how to structure a small REST API with business rules

## When to choose
- you want a realistic, well-scoped backend exercise for practice or portfolio
- you are preparing to interview with PicPay or a similar fintech
- you want a reference spec for teaching REST API design and transactional business rules

## When to avoid
- you need production-ready payment processing software
- you expect runnable code rather than a challenge specification
- you need a maintained library with a license and releases for integration
