thor-devkit.rs

Rust library to aid coding with VeChain: wallets, transactions signing, encoding and verification, smart contract ABI interfacing, etc.

This library acts primary as a proxy to several underlying libraries, with the addition of some VeChain-specific toolchain components.

Usage

One of possible use cases can be transaction creation and signing.

Here is how you may approach it. Let's transfer a few VET to another account.

To do so, we need to create a transaction and encode it into broadcastable bytes.

use thor_devkit::transactions::{Transaction, Clause};
use thor_devkit::hdnode::{Mnemonic, Language, HDNode};

let transaction = Transaction {
    chain_tag: 1,
    block_ref: 0xaabbccdd,
    expiration: 32,
    clauses: vec![
        Clause {
            to: Some(
                "0x7567d83b7b8d80addcb281a71d54fc7b3364ffed"
                    .parse()
                    .unwrap(),
            ),
            value: 10000.into(),
            data: b"\x00\x00\x00\x60\x60\x60".to_vec().into(),
        },
    ],
    gas_price_coef: 128,
    gas: 21000,
    depends_on: None,
    nonce: 0xbc614e,
    reserved: None,
    signature: None,
};
let mnemonic = Mnemonic::from_phrase(
    "ignore empty bird silly journey junior ripple have guard waste between tenant",
    Language::English
).expect("Must be correct");
let wallet = HDNode::build().mnemonic(mnemonic).build().expect("Builds");
let signed = transaction.sign(&wallet.private_key().expect("Must be non-restricted").private_key());
println!("{:02x?}", signed.to_broadcastable_bytes());
