# Evolve

> Modular Rust SDK for building blockchain applications with Ethereum compatibility

## Docs

- [Collections](/reference/collections): Type-safe storage primitives for module state.
- [Macros](/reference/macros): Evolve provides procedural macros to eliminate boilerplate in module development.
- [Pre-built Modules](/reference/prebuilt): Evolve includes ready-to-use modules for common functionality.
- [Standards](/reference/standards): Evolve provides interface standards for common patterns.
- [Production Deployment](/operating/production): Guidelines for running Evolve in production.
- [Server Configuration](/operating/server): Configure and run an Evolve node.
- [Module Architecture](/modules/architecture): The Evolve module system uses an account-centric model where every piece of application logic is an account.
- [Creating Modules](/modules/creating): This guide walks through creating a complete module from scratch.
- [Error Handling](/modules/errors): Evolve uses error codes for compact, deterministic error handling.
- [Storage](/modules/storage): Evolve provides type-safe, collision-free storage primitives for module state.
- [Testing](/modules/testing): Evolve provides multiple testing levels: unit tests with MockEnv, integration tests with TestApp, and simulation tests with SimTestApp.
- [Installation](/getting-started/installation): **Rust 1.86.0** or later
- [Quickstart](/getting-started/quickstart): Build your first account module in 5 minutes.
- [Running the Testapp](/getting-started/testapp): The `testapp` crate is a complete example application demonstrating all Evolve features.
- [Transactions](/ethereum/transactions): Evolve supports Ethereum-compatible transactions with EIP-2718 typed transactions and EIP-1559 gas pricing.
- [Wallet Integration](/ethereum/wallets): Evolve is compatible with standard Ethereum wallets.
- [Accounts](/concepts/accounts): Everything in Evolve is an account. This account-centric model is the foundation of the entire system.
- [Concurrency Model](/concepts/concurrency): Evolve uses a hybrid sync/async model optimized for deterministic execution while maximizing performance where possible.
- [Determinism](/concepts/determinism): All module code must be deterministic. Given identical inputs, execution must produce identical outputs on all nodes. Violating determinism causes consensus failures.
- [State Transition Function](/concepts/stf): The STF is the core execution engine. It processes blocks of transactions deterministically, transforming state from one consistent snapshot to the next.
- [gRPC API](/apis/grpc): Evolve exposes a gRPC API for high-performance programmatic access. The gRPC interface is ideal for:
- [JSON-RPC](/apis/json-rpc): Evolve provides a full Ethereum-compatible JSON-RPC 2.0 API.
- [Schema Introspection](/apis/schema-introspection): The schema introspection API allows RPC clients to discover all available modules and their query/exec functions at runtime.
