near-ledger-rs

它是NEAR <-> Ledger传输

提供一系列可以执行的命令，用于与安装在Ledger设备上的NEAR应用通信

• 通过HD路径从Ledger设备读取公钥
• 签名交易

示例

从Ledger获取公钥

use near_ledger::get_public_key;
use slipped10::BIP32Path;
use std::str::FromStr;

let hd_path = BIP32Path::from_str("44'/397'/0'/0'/1'").unwrap();
let public_key = get_public_key(hd_path).unwrap();
println!("{:#?}", public_key);

技巧

要将答案转换为 near_crypto::PublicKey，请执行以下操作

let public_key = near_crypto::PublicKey::ED25519(
    near_crypto::ED25519PublicKey::from(
        public_key.to_bytes(),
    )
);

如何签名交易

use near_ledger::{sign_transaction, SignTarget};
use near_primitives::borsh::BorshSerialize;
use slipped10::BIP32Path;
use std::str::FromStr;

let hd_path = BIP32Path::from_str("44'/397'/0'/0'/1'").unwrap();
let borsh_transaction = near_unsigned_transaction.try_to_vec().unwrap();
let signature = sign_transaction(SignTarget::BorshUnsignedTx(borsh_transaction), hd_path).unwrap();
println!("{:#?}", signature);

技巧

要将答案转换为 near_crypto::Signature，请执行以下操作

let signature = near_crypto::Signature::from_parts(near_crypto::KeyType::ED25519, &signature)
    .expect("Signature is not expected to fail on deserialization");
