setup-stylus-contracts

Original：🇺🇸 English

Translated

Set up a Stylus smart contract project with OpenZeppelin Contracts for Stylus on Arbitrum. Use when users need to: (1) install Rust toolchain and WASM target for Stylus, (2) create a new Cargo Stylus project, (3) add OpenZeppelin Stylus dependencies to Cargo.toml, or (4) understand Stylus import conventions and storage patterns for OpenZeppelin.

Stylus Setup

Rust & Cargo Stylus Setup

Install the Rust toolchain and WASM target:

bash

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup target add wasm32-unknown-unknown

Install the Cargo Stylus CLI:

bash

cargo install --force cargo-stylus

Create a new Stylus project:

bash

cargo stylus new my_project

A Rust nightly toolchain is required. The project should include a
rust-toolchain.toml
specifying the nightly channel,
rust-src
component, and
wasm32-unknown-unknown
target. Check the rust-contracts-stylus repo for the current recommended nightly date.

Adding OpenZeppelin Dependencies

Look up the current version from crates.io/crates/openzeppelin-stylus before adding. Add to

Cargo.toml

:

toml

[dependencies]
openzeppelin-stylus = "=<VERSION>"

Enable the

export-abi

feature flag for ABI generation:

toml

[features]
export-abi = ["openzeppelin-stylus/export-abi"]

The crate must be compiled as both a library and a cdylib:

toml

[lib]
crate-type = ["lib", "cdylib"]

Import Conventions

Imports use

openzeppelin_stylus

(underscores) as the crate root:

rust

use openzeppelin_stylus::token::erc20::{Erc20, IErc20};
use openzeppelin_stylus::access::ownable::{Ownable, IOwnable};
use openzeppelin_stylus::utils::pausable::{Pausable, IPausable};
use openzeppelin_stylus::utils::introspection::erc165::IErc165;

Contracts use

#[storage]

and

#[entrypoint]

on the main struct, embedding OpenZeppelin components as fields:

rust

#[entrypoint]
#[storage]
struct MyToken {
    erc20: Erc20,
    ownable: Ownable,
}

Public methods are exposed with

#[public]

and

#[implements(...)]

. The canonical pattern uses an empty impl block for dispatch registration, plus separate trait impl blocks:

rust

#[public]
#[implements(IErc20<Error = erc20::Error>, IOwnable<Error = ownable::Error>)]
impl MyToken {}

#[public]
impl IErc20 for MyToken {
    type Error = erc20::Error;
    // delegate to self.erc20 ...
}

Top-level modules:

access

,

finance

,

proxy

,

token

,

utils

.

Build & Deploy Basics

Validate the contract compiles to valid Stylus WASM:

bash

cargo stylus check

Export the Solidity ABI:

bash

cargo stylus export-abi

Deploy to an Arbitrum Stylus endpoint:

bash

cargo stylus deploy --endpoint="<RPC_URL>" --private-key-path="<KEY_FILE>"
