About this app

Firmas.io is your personal legal wallet. Manage every contract in your life — rental, insurance, utilities, family agreements — from a single place, with real privacy.

REAL PRIVACY, NOT PROMISES
Your contracts live only on your device. Our servers cannot read your information — not even us. When you negotiate with another party, the data travels end-to-end encrypted (AES-256-GCM).

NEGOTIATE FAIRLY
Share an invite link and negotiate the terms of your contract point by point. Each side sets their preferences and an algorithm calculates a fair compromise for both. No pressure, no fine print.

AI ANALYSIS
Scan any contract — electricity bill, insurance policy, lease — and the AI explains in plain language what it says, which risks it carries, and which dates matter.

ADVANCED ELECTRONIC SIGNATURE
Sign contracts with a Simple Electronic Signature (SES) or an Advanced Electronic Signature (AES) built on ECDSA P-256 cryptography, designed in line with eIDAS. Every signature is anchored to the blockchain for cryptographic verification.

FOR YOUR WHOLE CONTRACTUAL LIFE
- Rental: negotiate and sign leases under local law
- Family: wills, family agreements, mutual-consent divorce
- Utilities: power, gas, water, internet — understand the terms
- Insurance: home, auto, health, life — make sense of your policy
- Personal: loans between people with clear conditions
- Services: terms of use for apps and platforms

BLOCKCHAIN VERIFICATION
A cryptographic hash of each signed contract is anchored to the Base L2 blockchain. This lets anyone cryptographically verify that the document existed at that exact moment, without ever revealing its contents. Cost to you: zero.
