Trustless digital signatures for the decentralized web. Filosign replaces fragile platform trust with permanent mathematical proof, ensuring your agreements are secure, verifiable, and immutable on the Filecoin network.
Traditional e-signature platforms require you to trust a centralized provider. Filosign eliminates this risk by anchoring every signature to the blockchain, providing mathematical certainty that your documents cannot be altered, lost, or invalidated.
- 🔐 Post-Quantum Security: Future-proof cryptography resistant to quantum computing
- ⛓️ Blockchain Anchored: Every signature is a permanent, verifiable transaction
- 🔒 End-to-End Encrypted: Documents encrypted from creation to delivery
- 🌐 Decentralized Storage: Files stored on Filecoin's resilient network
- 💰 Crypto Payments: USDFC subscriptions with no intermediary fees
Getting started with Filosign takes just a few minutes:
- Connect Wallet: Link your Web3 wallet (MetaMask, Coinbase, etc.)
- Create Account: Set up dual-factor authentication with PIN + wallet
- Upload & Share: Upload documents and invite signers

Link your Web3 wallet and set up dual-factor security with a PIN. Your cryptographic keys are generated client-side - we never store your private information.
Documents are encrypted on your device before upload. Using quantum-resistant algorithms, each file gets its own unique encryption key.
Invite signers and share documents through our permission system. Recipients can only access files they've been explicitly granted permission to view.
Signers create signatures using familiar methods (draw, type, or upload). Every signature is cryptographically verified and permanently anchored to the blockchain.
All actions are immutably recorded on-chain. Anyone can independently verify the authenticity, timestamp, and integrity of any signed document.
- Your private keys never leave your device
- Documents are encrypted before transmission
- Server acts only as a coordinator, never storing sensitive data
Built with post-quantum cryptographic algorithms that remain secure even against future quantum computers.
Every signature, timestamp, and document hash is permanently recorded on the Filecoin network, providing mathematical proof of authenticity.
