# What is the LIFT Challenge?
7+
8+
The LIFT Challenge Real Digital was a groundbreaking initiative launched by the Central Bank of Brazil (BC) in partnership with Fenasbac. This special edition of the LIFT (Laboratório de Inovações Financeiras e Tecnológicas) program created a collaborative sandbox environment to explore innovative applications of DREX, Brazil's CBDC.
9+
10+
## Challenge Overview
11+
12+
The initiative invited market participants to develop Minimum Viable Products (MVPs) that would demonstrate practical applications and assess the technological feasibility of a CBDC in Brazil's financial ecosystem.
13+
14+
### Focus Areas
15+
16+
The challenge prioritized four key categories for online use cases:
17+
18+
- **Delivery versus Payment (DvP)**
19+
- Settlement of transactions with digital assets
20+
- Both native and tokenized asset support
21+
22+
- **Payment versus Payment (PvP)**
23+
- Focus on currency exchange facilitation
24+
- Cross-border payment solutions
25+
26+
- **Internet of Things (IoT)**
27+
- Algorithmic settlement
28+
- Machine-to-machine transactions
29+
30+
- **Decentralized Finance (DeFi)**
31+
- CBDC-based protocols
32+
- Regulatory compliance integration
33+
34+
### Key Evaluation Criteria
35+
36+
Projects were assessed based on several critical factors:
37+
38+
- Interoperability with existing payment systems
39+
- Scalability for nationwide retail applications
40+
- Data privacy compliance
41+
- Programmability potential
42+
43+
