Zentro

Zentro digitizes the entire credit process still handled on paper from loan applications to signed contracts. We tokenize those promissory notes so they can sell their portfolio and get liquidity

Inspiration

Small retailers across Latin America still approve credit on paper, manage risk manually, and struggle with cash flow because they must wait months to recover their money. After speaking with dozens of merchants, we realized the problem wasn’t lack of willingness — it was lack of tools. Zentro was born from the idea of giving these merchants trust, speed, and liquidity through technology.

What it does

Zentro digitizes the entire credit workflow for small retailers — from the loan application to approval, contract generation, and identity validation. Once the credit is issued, Zentro converts the promissory note into a digital asset secured on blockchain, allowing merchants to sell their receivables and access instant liquidity.

In simple terms: Zentro turns paper-based credit into a fully digital, trustworthy, and liquid asset.

How we built it

• Built the core platform using Lovable for rapid no-code/low-code development.
• Integrated smart contract signing and anchoring using blockchain (testnet).
• Automated identity validation and contract flow using APIs.
• Created a lightweight workflow engine to guide merchants from credit application to finalized contract.
• Designed a modular system that can later evolve into a full appchain or DAS (Decentralized Autonomous System).

⸻

Challenges we ran into

• Building a functional solution without a development background meant learning by doing — and breaking many things.
• Streamlining a process that varies widely between merchants.
• Integrating blockchain in a way that feels invisible and simple for non-technical users.
• Designing a smooth experience despite limited time and resources.
• Ensuring contracts and flows were legally aligned while keeping the UX frictionless.

⸻

Accomplishments that we’re proud of

• Shipping a working version 1.0 in just a few months from scratch.
• Digitizing a full credit process that was originally done entirely on paper.
• Successfully anchoring contracts and credit data on blockchain.
• Creating a system that real merchants said they would use.
• Building everything through vibe-coding, AI assistance, and determination.

⸻

What we learned

• You don’t need to be a developer to build powerful tools — you need clarity, iteration, and AI.
• Blockchain is incredibly impactful when used for trust, not hype.
• Merchants want simpler solutions, not more complicated tech.
• Real problems are solved by listening, not just coding.
• Moving fast with no-code + smart contracts is possible — and effective.

⸻

What’s next for Zentro

• Deploy the credit contracts and asset tokenization on a dedicated appchain.
• Build the liquidity marketplace where investors can buy tokenized receivables.
• Integrate more automated risk scoring for credit approvals.
• Expand Zentro into a full DAS (Decentralized Autonomous System) for credit operations.
• Pilot with real retailers across Colombia and then scale to Latin America.
• Launch Zentro as a SaaS platform for merchants, lenders, and financial operators.
