Import/Recovery

To perform the key import process for MPC wallets, you need to:

1. Import the mnemonic phrase and derive private keys for child wallets.

2. Generate a list of KeyGenWallet using the derived private keys and public wallet addresses.

3. Recall the createMnemonicWallet method with the same input list of KeyGenWallet.

   • wallets: A list of KeyGenWallet to perform keygen. Each item requires: - secret: The private key of the Child Wallet (derived from the mnemonic phrase). - walletAddress: The public address or public key of the Child Wallet. - ChainId: The chain name (e.g., ethereum, solana). - ecType: The cryptographic algorithm type (eddsa, ecdsa).

4. When receiving the backup from createMnemonicWallet() , please ensure that the server shards of the newly created Paillier group and Keygen group are stored in a safe and secure location.

Example:

val walletResponse = client.createMnemonicWallet(
    name = "KeyGenGroupID123",
    numParties = 2,
    mnemonicPhrase = "import your mnemonic phrase ",
    wallets = listOf(
        KeyGenWallet(
            secret = "derived private key",
            walletAddress = "0xYourWalletAddress",
            chainId = "ethereum",
            ecType = "ecdsa"
        )
    )
)
walletResponse.masterWallets.forEach { masterWallet ->
    masterWallet.forEach { wallet
        println("keyIdentity: ${wallet.keyIdentity} - ecType: ${wallet.ecType} - address: ${wallet.address}")
    }
}
