2.4 Restore your wallet from mnemonic

If users change or loose their phone they need a way to re-enter the seed phrase and recover the wallet on a new phone.

Use cases

Enter the 24 words of your mnemonic to re-generate the wallet.

Tools

The Sacco library, our own open source tool to sign and send transactions to any Cosmos SDK based blockchain, including Commercio.network.

Functions and APIs

• Wallet derive.

Background

From Wikipedia:

Mnemonics make use of elaborative encoding, retrieval cues, and imagery as specific tools to encode any given information in a way that allows for efficient storage and retrieval. Mnemonics aid original information in becoming associated with something more accessible or meaningful—which, in turn, provides better retention of the information.

Step by step sequence

1. Enter the 24 words of mnemonic;
2. Call the wallet derive function;
3. Finally, the result is a new wallet.

Code Examples

Here's an example of the implementation in all the available languages.

Dart

final mnemonicString = 'final random flame cinnamon grunt hazard easily mutual resist pond solution define knife female tongue crime atom jaguar alert library best forum lesson rigid';

final mnemonic = mnemonicString.split(' ');
final networkInfo = NetworkInfo(bech32Hrp: 'did:com:', lcdUrl: 'http://localhost:1317');

final wallet = Wallet.derive(mnemonic, networkInfo);

Kotlin

val mnemonicString = "final random flame cinnamon grunt hazard easily mutual resist pond solution define knife female tongue crime atom jaguar alert library best forum lesson rigid"

val mnemonic = listOf(mnemonicString)
val networkInfo = NetworkInfo(bech32Hrp = "did:com:", lcdUrl = "http://localhost:1317")

val wallet = Wallet.derive(mnemonic = mnemonic, networkInfo = networkInfo)

C#

String mnemonicString = "final random flame cinnamon grunt hazard easily mutual resist pond solution define knife female tongue crime atom jaguar alert library best forum lesson rigid";

List<String> mnemonic = new List<String>(mnemonicString.Split(" ", StringSplitOptions.RemoveEmptyEntries));
static commercio.sacco.lib.NetworkInfo networkInfo = new commercio.sacco.lib.NetworkInfo(
                bech32Hrp: "did:com:",
                lcdUrl: "http://localhost:1317"
              );

var wallet = commercio.sacco.lib.Wallet.derive(mnemonic, networkInfo);
