Zama primary-source snapshot

Fetched: 2026-04-27 UTC

1) Documentation homepage

Source: https://docs.zama.org/homepage/readme.md

Selected excerpts from the official docs:

A suite of tools and libraries for building confidential smart contracts and dApps on any chains.

Additional signals from the source:

  • The docs homepage is more informative than the marketing homepage for understanding the crypto-facing product surface
  • Zama presents the protocol as a bundle of developer surfaces rather than as a single chain or token project
  • The homepage explicitly foregrounds Quick Start, Solidity Guides, Relayer SDK Guides, Protocol Apps, code examples, and a protocol litepaper
  • The same docs homepage also lists TFHE-rs, Concrete, and Concrete ML, showing that Zama’s blockchain work sits on top of a broader FHE tooling stack

2) Quick start tutorial

Source: https://docs.zama.org/protocol/solidity-guides/getting-started/quick-start-tutorial

Selected excerpts from the official docs:

This tutorial guides you to start quickly with Zama’s Fully Homomorphic Encryption (FHE) technology for building confidential smart contracts.

In about 30 minutes, you’ll go from a basic Solidity contract to a fully confidential one using FHEVM.

Additional signals from the source:

  • The quick start makes clear that Zama wants Ethereum/Solidity developers to adopt FHE without leaving familiar tooling
  • Hardhat is the main onboarding path in the current docs, which makes the project look like developer infrastructure rather than only protocol research
  • The tutorial flow is explicitly about transforming a normal contract into a confidential one, which is a useful categorization clue

3) Solidity guides / encrypted-contract surface

Sources:

Selected excerpts from the official docs:

The Solidity guides and library let you build confidential smart contracts in standard Solidity.

Use encrypted Solidity types like ebool, euint8...euint256, and eaddress.

Run arithmetic, bitwise, comparison, and conditional logic on encrypted values.

The official web applications are just two: Apps.

Staking — for staking ZAMA tokens and managing staking positions.

Portfolio — for checking confidential balances and handling shield, unshield, and confidential transfer actions.

Additional signals from the sources:

  • The docs expose more than basic encrypted math: they cover access control, encrypted randomness, symbolic execution, and decryption permissions
  • Higher-level confidential building blocks include ERC7984 confidential tokens, ERC20-to-ERC7984 wrapping, confidential vesting wallets, and encrypted voting utilities
  • The existence of official staking and portfolio apps shows that Zama is not only a library provider; it is also shipping protocol-facing product surfaces around token participation and private asset management

4) FHEVM repository / architecture surface

Source: https://github.com/zama-ai/fhevm

Selected excerpts from the public repo README:

FHEVM is the core framework of the Zama Confidential Blockchain Protocol.

It enables confidential smart contracts on EVM-compatible blockchains by leveraging Fully Homomorphic Encryption (FHE), allowing encrypted data to be processed directly onchain.

gateway-contracts/: Smart contracts managing the gateway between on-chain and off-chain components.

host-contracts/: Smart Contracts deployed on the host chain for orchestrating FHE workflows.

coprocessor/: Rust-based coprocessor implementation for FHE operations.

kms-connector/: Interface for integrating with Key Management Services (KMS) to handle encryption keys securely.

Additional signals from the source:

  • The repo makes the architecture unusually legible for categorization because it shows a full protocol stack rather than a thin Solidity package
  • The README emphasizes confidentiality plus composability, which is important because Zama is not framing this as an isolated privacy add-on or mixer-style product
  • The same README lists concrete use cases like confidential transfers, tokenization, blind auctions, confidential voting, onchain games, and encrypted DIDs
  • The repo also links an official fhevm-whitepaper.pdf, which was saved locally during this scouting pass

5) GitHub organization surface

Source: https://github.com/zama-ai

Selected signals from the public org page:

TFHE-rs: A Pure Rust implementation of the TFHE Scheme for Boolean and Integer Arithmetics Over Encrypted Data.

FHEVM, a full-stack framework for integrating Fully Homomorphic Encryption (FHE) with blockchain applications

Concrete: TFHE Compiler that converts python programs into FHE equivalent

Concrete ML: Privacy Preserving ML framework using Fully Homomorphic Encryption (FHE)

Additional signals from the source:

  • The org page is useful because it shows that Zama is not only a blockchain protocol team; it is a broader FHE infrastructure company with crypto as one major deployment surface
  • That broader repo inventory helps explain why the protocol docs, cryptography libraries, and licensing model need to be read together

6) Licensing / business-model post

Source: https://www.zama.org/post/open-source

Selected excerpts from the official post:

At Zama, we have thoughtfully chosen the BSD3-clear dual licensing model.

We want to allow anyone to use, fork, extend and distribute our software for free for development, research, prototyping and experimentation purposes.

Profitability is covered by our commercial license, that includes both software and patent usage rights.

Additional signals from the source:

  • This is unusually important primary-source context because the commercialization model is part of how Zama should be understood as infrastructure
  • The post makes clear that open source alone does not equal unrestricted commercial use in Zama’s model
  • That BSD3-clear-plus-patent-license structure makes Zama look less like a pure public-good research lab and more like a commercial cryptography platform with a protocol ecosystem on top

7) Whitepaper

Source: https://raw.githubusercontent.com/zama-ai/fhevm/main/fhevm-whitepaper.pdf

Saved locally as:

  • research/crypto/whitepapers/zama-fhevm-whitepaper.pdf

Additional signals from the source:

  • The public FHEVM repo directly links the whitepaper as the technical overview for the framework’s cryptographic design
  • Zama’s docs separately point to a protocol litepaper, so the whitepaper and docs should be read together rather than treated as one complete source of truth

Notes

  • Zama appears best cataloged as confidential blockchain protocol / FHE cryptography infrastructure / encrypted smart-contract framework / open-source cryptography company.
  • The strongest categorization clue is that the docs + repos jointly expose a full-stack confidential-compute product surface, while the licensing post clarifies that this is also a commercial cryptography platform rather than only an academic or open-source effort.
  • Official documentation and GitHub surfaces are currently more revealing than the main marketing homepage for the crypto library’s purposes.
