Rust algonaut

Rust algonaut aims at becoming a rusty SDK for Algorand. Please, be aware that this crate is a work in progress.

use algonaut::algod::AlgodBuilder;
use algonaut::core::MicroAlgos;
use algonaut::transaction::{Pay, TxnBuilder};
use algonaut_transaction::account::Account;
use std::error::Error;

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let algod = AlgodBuilder::new()
        .bind("http://localhost:4001")
        .auth("aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa")
        .build_v2()?;

    // an account with some funds
    let from_account = Account::from_mnemonic("fire enlist diesel stamp nuclear chunk student stumble call snow flock brush example slab guide choice option recall south kangaroo hundred matrix school above zero")?;

    let to_address = "2FMLYJHYQWRHMFKRHKTKX5UNB5DGO65U57O3YVLWUJWKRE4YYJYC2CWWBY".parse()?;

    // algod has a convenient method that retrieves basic information for a transaction
    let params = algod.transaction_params().await?;

    // we are ready to build the transaction
    let t = TxnBuilder::new()
        .sender(from_account.address())
        .first_valid(params.last_round)
        .last_valid(params.last_round + 10)
        .genesis_id(params.genesis_id)
        .genesis_hash(params.genesis_hash)
        .fee(MicroAlgos(10_000))
        .payment(
            Pay::new()
                .amount(MicroAlgos(123_456))
                .to(to_address)
                .build(),
        )
        .build();

    // we need to sign the transaction to prove that we own the sender address
    let signed_t = from_account.sign_transaction(&t)?;

    // broadcast the transaction to the network
    let send_response = algod.broadcast_signed_transaction(&signed_t).await?;

    println!("Transaction ID: {}", send_response.tx_id);

    Ok(())
}

Objectives

• Example-driven API development
• Async requests
• Builder pattern and sensible defaults
• Modularity
• Clear error messages
• Thorough test suite
• Comprehensive documentation

Crates

algonaut has a modular structure and is composed of multiple crates.

• algonaut_client contains clients for algod, kmd, and indexer RPC APIs.
• algonaut_core defines core structures for Algorand like: Address, Round, MicroAlgos, etc.
• algonaut_crypto contains crypto utilities such as: ed25519 and mnemonics.
• algonaut_encoding implements encoding utility functions such as serde visitors.
• algonaut_transaction support developers in building all kinds of Algorand transactions.

Planned:

• algonaut_teal will add validators, templates, and dryrun helpers.

Integrations

• Yew example
• iOS example (experimental)
