Aptos Rust SDK v2

A user-friendly, idiomatic Rust SDK for the Aptos blockchain with feature parity to the TypeScript SDK.

Features

• Full Blockchain Interaction: Connect, explore, and interact with the Aptos blockchain
• Multiple Signature Schemes: Ed25519, Secp256k1, Secp256r1 (P-256), and BLS12-381
• Transaction Building: Fluent builder pattern for constructing transactions
• Account Management: Single-key, multi-sig, and keyless (OIDC) accounts
• Type Safety: Strong Rust type system for Move contract interactions
• Modular Design: Feature flags to include only what you need

Quick Start

Add to your Cargo.toml:

[dependencies]
aptos-sdk = "0.3"

Basic usage:

use aptos_sdk::{Aptos, AptosConfig};
use aptos_sdk::account::{Account, Ed25519Account};

#[tokio::main]
async fn main() -> anyhow::Result<()> {
    // Connect to testnet
    let aptos = Aptos::new(AptosConfig::testnet())?;

    // Create a new account
    let account = Ed25519Account::generate();
    println!("Address: {}", account.address());

    // Check balance
    let balance = aptos.get_balance(account.address()).await?;
    println!("Balance: {} octas", balance);

    Ok(())
}

Feature Flags

Development

Building

# Build with default features
cargo build -p aptos-sdk

# Build with all features
cargo build -p aptos-sdk --all-features

# Build with specific features only
cargo build -p aptos-sdk --features "ed25519,secp256r1,bls"

# Check compilation (faster than build)
cargo check -p aptos-sdk --all-features

# Release build (optimized)
cargo build -p aptos-sdk --release --all-features

Linting

# Run clippy lints
cargo clippy -p aptos-sdk --all-features -- -D warnings

# Check formatting
cargo fmt -p aptos-sdk -- --check

# Format code
cargo fmt -p aptos-sdk

Testing

Unit Tests

# Run unit tests with default features
cargo test -p aptos-sdk

# Run tests with all features
cargo test -p aptos-sdk --all-features

# Run tests with specific features
cargo test -p aptos-sdk --features "full"

# Run a specific test by name
cargo test -p aptos-sdk test_name

# Run tests with output visible
cargo test -p aptos-sdk -- --nocapture

# Run doc tests only
cargo test -p aptos-sdk --doc

# Run library tests only (no integration tests)
cargo test -p aptos-sdk --lib

E2E Tests

E2E tests require a running Aptos localnet:

# Terminal 1: Start localnet
aptos node run-localnet

# Terminal 2: Run E2E tests
cargo test -p aptos-sdk --features "e2e" -- --ignored

Behavioral Tests

The SDK includes Gherkin-based behavioral specification tests:

# Run behavioral tests (from workspace root)
cd specifications/tests/rust
cargo test

# Run with verbose output
cargo test -- --nocapture

Code Coverage

# Unit tests only (default)
cargo tarpaulin -p aptos-sdk --features "full" --skip-clean

# Include E2E tests (requires localnet)
cargo tarpaulin -p aptos-sdk --features "full,e2e" --ignored --skip-clean --timeout 300

# Or use the helper script
./scripts/coverage.sh        # Unit tests only
./scripts/coverage.sh e2e    # Include E2E tests
./scripts/coverage.sh ci     # CI mode with HTML/XML output

See tarpaulin.toml for coverage configuration profiles.

Generating Documentation

# Generate and open documentation
