The methods supported by the aptos-ledger are:

• get_app_version()

Examples

Get Public Key from your Aptos account on Ledger

use aptos_ledger::get_public_key;

let public_key = match get_public_key(false);
println!("Public Key: {:?}", public_key);
// "Public Key: ______"

Sign Transaction

Currently we only support derivative path at index 0, and the transaction has to be serialized using BCS format

use aptos_ledger::sign_txn;
use bcs;

let utf8_str = "my transaction";
let signed_txn = sign_txn(to_bytes(utf8_str)?);
