setup-stylus-contracts: Workflow Automation for AI Agents | OpenAgentSkill

Overview

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:

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

Install the Cargo Stylus CLI:

cargo install --force cargo-stylus

Create a new Stylus project:

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:

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

Enable the export-abi feature flag for ABI generation:

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

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

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

Import Conventions

Imports use openzeppelin_stylus (underscores) as the crate root:

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:

#[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:

#[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:

cargo stylus check

Export the Solidity ABI:

cargo stylus export-abi

Deploy to an Arbitrum Stylus endpoint:

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

# 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](https://github.com/OpenZeppelin/rust-contracts-stylus) for the current recommended nightly date.

## Adding OpenZeppelin Dependencies

Look up the current version from [crates.io/crates/openzeppelin-stylus](https://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

```bash
cargo stylus export-abi
```

Deploy to an Arbitrum Stylus endpoint:

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

Review the source

Skill source recorded

Skill instructions are recorded. This is not a runtime test, safety guarantee or compatibility certification.

Review before install: Avoid automatic install

Dependency or permission surface needs review
Permission surface may require sandboxing
Financial research output is not financial advice; require human review before any live investment decision
Financial research output is not financial advice; require human review before any live investment decision.

Open full audit

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
