Plaintext to Encrypted

Convert plaintext values to encrypted handles. The contract emits an event, and the Runner encrypts the value off-chain inside a TEE. The encrypted data is stored in the Handle Gateway.

INFO

Plaintext to handle convertion is useful for initializing state variables and constants. For user-provided values, prefer fromExternal with the JS SDK to avoid exposing plaintext on-chain.

Usage

// Initialize encrypted state variables
euint256 initialBalance = Nox.toEuint256(0);
Nox.allowThis(initialBalance);

euint16 threshold = Nox.toEuint16(100);
Nox.allowThis(threshold);

ebool flag = Nox.toEbool(true);
Nox.allowThis(flag);

toEbool

function toEbool(bool value) internal returns (ebool)

Converts a plaintext boolean to an encrypted boolean handle.

toEaddress

function toEaddress(address value) internal returns (eaddress)
