Zama is the HTTPS moment for public blockchains

Just as HTTPS unlocked banking, commerce, and enterprise applications on the internet, the Zama Protocol enables institutions to operate on public blockchains through encrypted, verifiable, and programmable onchain computation using Fully Homomorphic Encryption (FHE).

Built for the industries where confidentiality isn't optional

For institutions, confidentiality and compliance aren't features. They're operating requirements to move their activities on public blockchains.

Confidential RWA Tokenization

Bring real-world assets onchain without exposing investor identities, deal terms, or cap table structure.

Confidential Payments and Payroll

Settle, invoice, and compensate onchain without making transaction amounts visible to the world.

Confidential DeFi and Trading

Trade, stake, and earn yield onchain without leaking positions, strategies, or counterparty data.

Confidential Token Distribution

Run vesting, airdrops, and allocations onchain without exposing who gets what.

Confidentiality is the missing piece to unlock institutional onchain finance

Until now, every transaction on a public blockchain exposed amounts and balances to anyone. For institutions operating in regulated markets, that exposure has made onchain finance a non-starter. Zama closes that gap, keeping amounts and balances confidential, while maintaining full verifiability and compliance.

Confidentiality should not require any architectural compromise

The Zama Protocol runs natively on any L1 or L2, using Fully Homomorphic Encryption (FHE) to keep amounts and balances encrypted at all times, including during processing. No new chain. No trusted intermediary. Full public verifiability.
