Bando: The On-Chain Spending Protocol

Bando is revolutionizing cryptocurrency spending by enabling users to purchase real-world goods and services using their digital assets. The protocol processes transactions through standardized payment infrastructure that connects to multiple service providers across various blockchain networks. Bando's two flagship products - a customizable Widget for frontend integration and a comprehensive Fulfiller API for backend systems - make it possible for any application to implement crypto spending capabilities. The protocol currently supports gift cards, airtime top-ups, bill payments, in-game items, and various digital goods across multiple chains including Solana.

How Does Bando Work?

Bando operates through a network of smart contracts that register and route user spend requests to verified fulfillers. When a user initiates a purchase, the protocol handles the entire flow from payment verification to order fulfillment, ensuring a seamless experience for both users and integrators.

The protocol's architecture is built around the concept of fulfillable products - items or services that can be delivered through Bando's fulfillment network. Each transaction follows a standardized flow:

1. Users select a product and initiate payment through an integrated application
2. Smart contracts verify and process the cryptocurrency payment
3. Verified fulfillers receive and execute the order
4. Users receive their purchased goods or services

This streamlined process enables near-instant delivery of digital goods while maintaining security and reliability throughout the transaction lifecycle.
