Installation

1. Configure your package manager

• Get a NPM token from a Silencelaboratories team.

• Configure your package manager to use the @silencelaboratories private NPM registry.

For npm and yarn v1 users:

• Create a .npmrc file in the root of your project and add the following line:

//registry.npmjs.org/:_authToken=${NPM_TOKEN}

For yarn v2 users:

• Create a .yarnrc.yml file in the root of your project and add the following line:

npmScopes:
  'silencelaboratories':
    npmAlwaysAuth: true
    npmRegistryServer: 'https://registry.npmjs.org'
    npmAuthToken: '${NPM_TOKEN}'

• Add the npm token as an environment variable, e.g., in a terminal session run:

export NPM_TOKEN=your-npm-token

2. Install the library

The @silencelaboratories/silent-shard-sdk is the main package that contains the high-level APIs for the MPC operations.

Each signature curve lives behind its own subpath and pulls in only the native package it needs — install just the curve(s) your app uses:

Curve	Subpath	Native package to install
ECDSA	/ecdsa	@silencelaboratories/dkls-sdk
EdDSA	/eddsa	@silencelaboratories/schnorr-sdk
ML-DSA	/mldsa	@silencelaboratories/mldsa-sdk

# Example: an ECDSA-only app
# Using npm
npm install @silencelaboratories/silent-shard-sdk @silencelaboratories/dkls-sdk
# or using yarn
yarn add @silencelaboratories/silent-shard-sdk @silencelaboratories/dkls-sdk

Requires React Native >= 0.77.

Android

No additional steps are required.

iOS

To run on the iOS platform, install pods before running the application:

cd ios && pod install

For Expo users:

For the current version of libraries, doesn't support Expo Go projects.

However, Expo users can use the Expo prebuild to extract native modules. Then auto-link should handle the linking of the native dependencies.

Usage

Curve APIs are reached only through their subpath. The package root exports the shared core (clients, storage, common types) — never curve code.

// ECDSA
import { createEcdsaDuoSession } from '@silencelaboratories/silent-shard-sdk/ecdsa';
// EdDSA
import { createEddsaDuoSession } from '@silencelaboratories/silent-shard-sdk/eddsa';
// ML-DSA
import { createMldsaDuoSession } from '@silencelaboratories/silent-shard-sdk/mldsa';
// Shared core
import { CloudWebSocketClient } from '@silencelaboratories/silent-shard-sdk';

Migrating to v3

v3 is a breaking change. The package root no longer re-exports curve APIs — importing createEcdsaDuoSession, EcdsaSession, etc. from @silencelaboratories/silent-shard-sdk will fail. Move every curve import to its subpath:

- import { createEcdsaDuoSession } from '@silencelaboratories/silent-shard-sdk';
+ import { createEcdsaDuoSession } from '@silencelaboratories/silent-shard-sdk/ecdsa';

Shared symbols (CloudWebSocketClient, StorageClient, MpcProtocol, MldsaLevels, …) stay on the root import. The benefit: an ECDSA-only app no longer bundles or links the EdDSA / ML-DSA native modules.
