@dynamic-labs/multi-wallet

Overview

The multi-wallet package provides utility functions for filtering and configuring wallet connectors in the Dynamic Labs SDK. It contains helper functions used by the main SDK to determine which wallets should be available based on project settings and enabled chains.

Key Features

• Wallet filtering: Filters wallet connectors based on enabled chains and project settings
• Configuration building: Creates configuration objects needed to instantiate wallet connectors
• Message generation: Generates standardized messages for wallet signature operations
• Provider filtering: Determines which authentication providers are enabled

Core Functions

getSupportedWallets(opts)

Main function that returns a filtered list of available wallet connectors based on:

• Project settings and enabled providers
• Platform compatibility (mobile/desktop)
• Wallet availability and installation status
• User preferences and disabled connectors

getWalletConnectorConstructorOptions(params)

Builds configuration options for wallet connector constructors, including:

• Network configurations for all supported chains
• API providers and RPC configurations
• Authentication modes and UI utilities
• WalletConnect project settings

getEnabledWallets(props)

Filters wallet connectors based on enabled chains. Takes an object with:

• enabledChains: Array of Chain types that are enabled
• getSupportedWalletOpts: Configuration options for getting supported wallets

generateMessageToSign(params)

Creates standardized messages for wallet signing operations. Takes a MessageParameters object with fields like:

• blockchain: The blockchain type (Chain)
• domain: The domain requesting the signature
• nonce: Unique nonce for the request
• publicKey: User's public key
• uri: URI of the requesting application
• Additional optional fields for chainId, statement, resources, etc.

getEnabledProviders(providers)

Filters providers to return only those that are enabled (have enabledAt set, or are MagicLink with providerProjectId, or are Turnkey).

getSupportedChainsForWalletConnector(walletBook, walletConnector)

Returns the supported chains for a specific wallet connector by combining information from the wallet book and the connector's native supported chains.

Usage

import { getSupportedWallets } from '@dynamic-labs/multi-wallet';

const wallets = getSupportedWallets({
  settings: projectSettings,
  walletConnectorsProp: walletConnectors,
  walletBook: walletBookData,
  chainRpcProviders: rpcProviders,
  // ... other options
});

Usage in Dynamic SDK

This package is primarily used internally by the Dynamic SDK React Core package. The main usage patterns are:

• Wallet List Building: getEnabledWallets is used to filter available wallets based on enabled chains
• Configuration Setup: getWalletConnectorConstructorOptions builds the options needed to create wallet connector instances
• Message Signing: generateMessageToSign creates SIWE-compliant messages for wallet authentication
