Built on [Alloy][alloy], op-alloy aggregates the OP stack's unique primitives from [Maili][maili],
to the subset of L1 types used by Optimistic rollups.

## Usage

The following crates are provided by `op-alloy`:

| Crate Name  | Description / Purpose                   | Version |
|-------------|-----------------------------------------|---------|
| [op-alloy-consensus](https://crates.io/crates/op-alloy-consensus) | Handles consensus-related logic         | [![version](https://img.shields.io/crates/v/op-alloy-consensus)](https://crates.io/crates/op-alloy-consensus) |
| [op-alloy-network](https://crates.io/crates/op-alloy-network) | Manages networking functionality        | [![version](https://img.shields.io/crates/v/op-alloy-network)](https://crates.io/crates/op-alloy-network) |
| [op-alloy-rpc-jsonrpsee](https://crates.io/crates/op-alloy-rpc-jsonrpsee) | RPC implementation using `jsonrpsee`    | [![version](https://img.shields.io/crates/v/op-alloy-rpc-jsonrpsee)](https://crates.io/crates/op-alloy-rpc-jsonrpsee) |
| [op-alloy-rpc-types-engine](https://crates.io/crates/op-alloy-rpc-types-engine) | Type definitions specific to RPC engine | [![version](https://img.shields.io/crates/v/op-alloy-rpc-types-engine)](https://crates.io/crates/op-alloy-rpc-types-engine) |
| [op-alloy-rpc-types](https://crates.io/crates/op-alloy-rpc-types) | Shared types used across RPC components | [![version](https://img.shields.io/crates/v/op-alloy-rpc-types)](https://crates.io/crates/op-alloy-rpc-types) |

## Development Status

`op-alloy` is currently in active development, and is not yet ready for use in production.

## Supported Rust Versions (MSRV)

The current MSRV (minimum supported rust version) is 1.86.

Unlike Alloy, op-alloy may use the latest stable release,
to benefit from the latest features.

The MSRV is not increased automatically, and will be updated
only as part of a patch (pre-1.0) or minor (post-1.0) release.

## Contributing

op-alloy is built by open source contributors like you, thank you for improving the project!

A [contributing guide][contributing] is available that sets guidelines for contributing.

Pull requests will not be merged unless CI passes, so please ensure that your contribution follows the
linting rules and passes clippy.

## `no_std`

op-alloy is intended to be `no_std` compatible, initially for use in [kona][kona].

The following crates support `no_std`.
Notice, provider crates do not support `no_std` compatibility.

| Crate Name                                               | Description / Purpose                   | Version |
|----------------------------------------------------------|-----------------------------------------|---------|
| [`op-alloy-consensus`]                 | Handles consensus-related logic         | [![version](https://img.shields.io/crates/v/op-alloy-consensus)](https://crates.io/crates/op-alloy-consensus) |
| [`op-alloy-rpc-types`]                 | Shared types used across RPC components | [![version](https://img.shields.io/crates/v/op-alloy-rpc-types)](https://crates.io/crates/op-alloy-rpc-types) |
| [`op-alloy-rpc-types-engine`]   | RPC types specific to the engine API    | [![version](https://img.shields.io/crates/v/op-alloy-rpc-types-engine)](https://crates.io/crates/op-alloy-rpc-types-engine) |

If you would like to add no_std support to a crate,
please make sure to update [scripts/check_no_std.sh][check-no-std].
