Developer Preview Features

1. Biometric MPC Wallets

// Android Biometric Binding
val authSession = BioAuth.Builder()
    .setHardwareSecurityLevel(SECURE_ELEMENT)
    .setAllowedAuthenticators(BIOMETRIC_STRONG)
    .setCryptoObject(CryptoObject(MPCOperation.SHARD_GEN))
    .build()

authSession.execute { crypto ->
    val shard = MPCShard.generate(
        masterKey = enclaveKey,
        bioFactor = crypto.biometricStamp
    )
    SafeStorage.writeShard(shard)
}

2. On-Device Agent Training

// Federated Learning Update
#[mobile_federated]
async fn update_agent_model(
    gradients: EncryptedTensor,
    proof: TrainingProof
) -> Result<ModelDelta> {
    let verified = zk_verify!(proof, gradients);
    let delta = secure_aggregate!(gradients);
    Ok(delta)
}

• Differential Privacy (ε=0.5, δ=1e-7)

• Homomorphic Encryption (CKKS Scheme)

• zkAttestation of Training Integrity
