FHEVM is a framework built by Zama to enable confidential smart contracts on EVM-compatible blockchains using Fully Homomorphic Encryption (FHE). It lets developers write Solidity contracts that handle encrypted inputs, encrypted state, arithmetic and logical operations on encrypted types, while maintaining privacy (data always encrypted), composability (encrypted state works alongside public state), and security (via threshold decryption, KMS, etc). The framework includes on-chain and off-chain components (contracts, coprocessors, gateway, utilities) to orchestrate the whole encrypted data pipeline.

Features

  • Solidity integration: write smart contracts with encrypted data types (e.g. euint, ebool, eaddress) using standard toolchains like Hardhat or Foundry
  • Programmable privacy: developer controls what parts of state/transactions are encrypted, who can decrypt via access control lists etc
  • Full range of operations on encrypted data: arithmetic, comparisons, boolean, bitwise, branching (including encrypted conditionals)
  • High precision integers (up to 256 bits) when using encrypted integer types
  • Security via threshold decryption / key management (KMS), ensuring no single actor can compromise encrypted state
  • Use of symbolic execution for on-chain FHE operations (i.e. handles/pointers emitted, off-chain coprocessor does heavy work), enabling efficiency and scalability

A low-code dashboard makes monitoring intuitive for any admin, while scripting and custom sensors give experts full control.

You shouldn't have to choose between a monitoring tool that's easy to use and one that's powerful enough for a complex environment. PRTG's low-code interface lets any admin build dashboards, set alerts and monitor devices without scripting, while custom sensors and full API access are there when your team needs deeper control. One platform, no compromise. Download a free 30-day trial now.
