• BIP39 seed is derived and kept only in native memory
• JS receives public keys and signatures only (ColdSigner)
• Used by @digitalshieldfe/example with holdMnemonicInJs: false

API

import {
  createNativeSecureKeyring,
  isNativeSecureKeyringAvailable,
} from "@digitalshieldfe/airgap-secure-keyring";

const keyring = await createNativeSecureKeyring();
await keyring.importMnemonic({ words: mnemonic });
const signer = keyring.asColdSigner();

Errors

When the native module is missing or unsupported, throws AirGapError:

| code | When | |--------|------| | NATIVE_SECURE_KEYRING_NOT_LINKED | TurboModule / bridge not linked | | NATIVE_SECURE_KEYRING_UNSUPPORTED | Platform or build without native impl |

import { isAirGapError, AirGapErrorCode } from "@digitalshieldfe/airgap-core";

if (!isNativeSecureKeyringAvailable()) {
  // show setup / rebuild instructions
}

PIN KDF native errors (NATIVE_PIN_KDF_NOT_LINKED) come from @digitalshieldfe/airgap-pin-kdf.
