Alloy

Alloy connects applications to blockchains.

Alloy is a rewrite of ethers-rs from the ground up, with exciting new features, high performance, and excellent docs.

ethers-rs will continue to be maintained until we have achieved feature-parity in Alloy. No action is currently needed from devs.

Overview

This repository contains the following crates:

alloy: Meta-crate for the entire project, including alloy-core
alloy-consensus - Ethereum consensus interface
alloy-contract - Interact with on-chain contracts
alloy-eips - Ethereum Improvement Proprosal (EIP) implementations
alloy-genesis - Ethereum genesis file definitions
alloy-json-rpc - Core data types for JSON-RPC 2.0 clients
alloy-network - Network abstraction for RPC types
alloy-node-bindings - Ethereum execution-layer client bindings
alloy-providers - Interface with an Ethereum blockchain
alloy-pubsub - Ethereum JSON-RPC publish-subscribe tower service and type definitions
alloy-rpc-client - Low-level Ethereum JSON-RPC client implementation
alloy-rpc-types - Ethereum JSON-RPC types
- alloy-rpc-engine-types - Ethereum execution-consensus layer (engine) API RPC types
- alloy-rpc-trace-types - Ethereum RPC trace types
alloy-signer - Ethereum signer abstraction
- alloy-signer-aws - AWS KMS signer implementation
- alloy-signer-gcp - GCP KMS signer implementation
- alloy-signer-ledger - Ledger signer implementation
- alloy-signer-trezor - Trezor signer implementation
alloy-transport - Low-level Ethereum JSON-RPC transport abstraction
- alloy-transport-http - HTTP transport implementation
- alloy-transport-ipc - IPC transport implementation
- alloy-transport-ws - WS transport implementation

Supported Rust Versions

Alloy will keep a rolling MSRV (minimum supported rust version) policy of at least 6 months. When increasing the MSRV, the new Rust version must have been released at least six months ago. The current MSRV is 1.75.

Note that the MSRV is not increased automatically, and only as part of a minor release.

Contributing

Thanks for your help improving the project! We are so happy to have you! We have a contributing guide to help you get involved in the Alloy project.

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

Note on `no_std`

Because these crates are primarily json-rpc focused, we do not intend to support no_std for them at this time.
