Wrap as Public Handle

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.

WARNING

The value you pass here is visible in plain text on-chain — anyone can read it on a block explorer. This is intentional for constants, state initialization, or wrapping values that are already public into handles for use with Nox primitives (which only accept handles as inputs).

If the value must stay private (e.g. a user-submitted amount, vote, or bid), it must be encrypted before the transaction is sent. → Accepting private user inputs

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);
