ChatMint lets anyone turn a simple text chat into an immutable, cryptographically signed NFT on Celo — acting as a free digital notary for informal loans, rentals, work agreements and promises in Africa & Latam.

Bring free, instant, blockchain-based proof-of-agreement to the 300+ million unbanked people in Africa and Latin America who today rely only on trust and handshakes.

In Latin America and Sub-Saharan Africa, more than 60% of adults are unbanked or underbanked and rely on informal agreements (loans between friends, rent payments, freelance work, farming partnerships, small supplier credit). These agreements total hundreds of billions of dollars yearly but have no cheap, trusted way to be proven.Traditional notaries are expensive (US$20–150 per document), slow, and inaccessible in rural areas. WhatsApp screenshots are easy to fake. When someone doesn’t pay back a loan or denies a verbal deal, the lender usually has no proof and loses everything. Women and low-income people are hit hardest because they have the least access to formal legal tools.Result: lower trust → fewer informal loans → slower local economies.

ChatMint is a dead-simple mobile chat where two or more people agree on something (loan, rent, salary, delivery date, etc.). When they are happy with the terms, any participant presses “Seal as Agreement”. Everyone signs once with their Celo wallet (Valora takes 3 seconds) and the entire conversation is minted as an ERC-721 NFT for less than US$0.003.The NFT contains:Full text + timestamps
Cryptographic signatures of every participant
Optional World ID proof that each wallet belongs to a unique human

Anyone (a community leader, arbiter, or even a local court) can verify forever that the agreement is authentic and untampered. No lawyers, no notary, no paperwork — just a chat that became legal-grade evidence.
