@qntx/nostr-native

Native libsecp256k1 verification and signing for @qntx/nostr on React Native (iOS/Android), via a Nitro C++ HybridObject over vendored libsecp256k1.

npm install @qntx/nostr-native @qntx/nostr react-native-nitro-modules

import { Keys, createEventVerifier } from "@qntx/nostr";
import { signing, verifySerialized } from "@qntx/nostr-native";
import { Relay } from "@qntx/nostr/relay";

// Verifier injection: relays verify incoming events natively.
const verifyEvent = createEventVerifier(verifySerialized);
const relay = await Relay.connect("wss://relay.example", { verifyEvent });

// Signing backend: `keys` signs on the same randomized native context.
const keys = Keys.fromSecretKey(secretKey, signing);

Requirements

• React Native with the New Architecture (Nitro Modules 0.37.x), iOS and Android only.
• Expo projects need a dev client / prebuild — the module compiles from source and cannot run in Expo Go.
• libsecp256k1 v0.8.0 is vendored under vendor/secp256k1 (MIT, see vendor/secp256k1/COPYING); its symbols are namespaced nostr_native_secp256k1_*, so the module links alongside other copies of libsecp256k1 in the same app.
• cpp/nostr_core.c is the platform-independent half of this package (context-in, status-code-out nostr_core_* functions over the vendored library); @qntx/nostr-wasm builds the same file for wasm32.
