null402 Hero Logo

Your position is not
hidden. It is null.

The first confidential lending protocol on Ethereum using Zama's fhEVM. All collateral, debt, and health factors are stored as encrypted values.

0 public exposures.
SECURITY
100% MEV resistance.
PRIVACY
fhEVM powered by Zama.
TECHNOLOGY
$0 targetable debt.
STABILITY

// PROTOCOL POWER

Lend. Borrow.
Remain Null.

null402 rewrites the rules of on-chain lending. By encrypting every position, we remove the information advantage of predatory bots and MEV searchers.

Encrypted Positions

Every collateral amount and debt balance is stored as an encrypted euint128. Only the borrower holds the decryption key.

Zero Liquidation Hunting

Bots cannot read your health factor. They cannot compute how close you are to liquidation, making targeting impossible.

The Protocol is Blind

Smart contracts operate on facts (isHealthy) without ever learning the underlying numbers (debt vs collateral).

FHE Health Checks

Solvency is enforced via homomorphic comparisons. We verify solvency without exposing a single decimal point.

Async Liquidations

Liquidation triggers use Zama's Gateway for asynchronous callback decryption, preventing atomic front-running attacks.

Immutable Solvency

The safety of the pool is mathematically guaranteed by the fhEVM, maintaining protocol health in complete privacy.

// DECENTRALIZED PRIVACY

Confidentiality at scale.

The null402 protocol runs on a decentralized network of fhEVM-compatible nodes. Each node performs homomorphic operations without ever seeing your data.

Zama fhEVM Core

Native support for encrypted integer operations at the EVM layer.

Secure Gateway

Decentralized gateway for secure, asynchronous decryption triggers.

NullOracle

Confidential price feeds that protect pool solvency.

// PROTOCOL SECURITY

Privacy is the ultimate security.

By using fully homomorphic encryption, null402 ensures that your lending positions remain invisible to everyone—even the protocol logic itself.
