Tandot 🎰

Did your tanda organizer run off with the money? Never again.

Trustless, AI-managed savings circles guaranteeing every payout via Arbitrum smart contracts and Bitso MXNB.

Slide 02 // The Crisis

The $40B Trust Problem

In Mexico, rotating savings circles (tandas) are the backbone of informal finance. But they rely entirely on the honesty of a human organizer.

ERROR: 1 in 3 tandas fail.

The organizer vanishes with the pooled funds. Zero recourse. Zero insurance. Communities lose money and trust.

Slide 03 // The Cure

Math & Machine Intelligence

1. GPT-4 Trust Scoring

We replace the human organizer with an unbiased AI agent. It analyzes behavior, financial history, and referral networks to dynamically score and match members safely.

2. Arbitrum Escrow

Funds are locked in a decentralized vault using MXNB (Peso stablecoin). No single person controls the pool. Payouts are executed by code, guaranteeing delivery.

Slide 04 // UX Flow

Three Steps. Zero Trust.

1

Join

AI evaluates your trust score (0-100) and matches you with a verified, low-risk group.

2

Contribute

Pay seamlessly in local currency via Bitso SPEI. Converted instantly to MXNB on Arbitrum.

3

Get Paid

Smart contract automatically disburses the pooled MXNB directly to your wallet on your turn.
