Getting started

Installation

ledger_sui: ^latest-version

For integration with the Ledger Flutter package, check out the documentation here.

Setup

Create a new instance of a SuiLedgerApp and pass an instance of your Ledger object.

final suiApp = SuiLedgerApp(ledger);

Usage

Get public key

Fetch the public key and address from the Ledger Nano device.

final result = await suiApp.getPublicKey(device);
print(result.publicKey); // Ed25519 public key
print(result.address);   // Sui address

Discover multiple accounts

Fetch a page of Sui accounts by derivation index.

final accounts = await suiApp.getAccountsWithDetails(
  device,
  startIndex: 0,
  count: 5,
);

for (final account in accounts) {
  print(account.accountIndex);
  print(account.addressHex);
}

Signing transactions

You can sign transactions using the SuiLedgerApp. The signing flow uses a block-chain protocol to handle large transactions:

final signature = await suiApp.signTransaction(
    device,
    transaction,
);
