# Ox

> Ethereum Standard Library

## Docs

- [Error Handling](/error-handling): Every function namespace in Ox exports an accompanying error type (`ErrorType`) and parser (`parseError`) that you can use to strongly type your `catch` statements, or inject into a custom type-safe error handling library (e.g. [`neverthrow`](https://github.com/supermacro/neverthrow), [`Effect`](https://effect.website/), etc.).
- [Imports & Bundle Size](/imports): There are two approaches to import Modules in Ox:
- [Installation](/installation): Install Ox via your package manager, a `<script>` tag, or build from source.
- [Platform Compatibility](/platform-compatibility): Platforms compatible with Ox

- [Application Binary Interface (ABI)](/guides/abi): The **Application Binary Interface (ABI)** is the standardized protocol for interacting with smart contracts in the Ethereum ecosystem. It defines how data is encoded and decoded for **Consumer (e.g. Application, Wallet, Server, etc) ↔ Contract** communication, as well as **Contract → Contract** communication.
- [Bytes & Hex](/guides/bytes-hex): When working with Ethereum, data can commonly be represented as either:
- [ECDSA & Signers](/guides/ecdsa): Ox exports utilities for the following ECDSA signers:
- [EIP-1193 Providers](/guides/eip-1193): [EIP-1193](https://eips.ethereum.org/EIPS/eip-1193) is a standard that defines a JavaScript Ethereum Provider API for interacting from an arbitrary JavaScript environment (e.g. Web Application, Server, etc) to the Ethereum network.
- [AES-GCM Encryption](/guides/encryption): [AES-GCM](https://cryptosys.net/pki/manpki/pki_aesgcmauthencryption.html) (AES with Galois/Counter Mode) is an encryption standard that combines high-performance encryption with built-in message integrity.
- [JSON-RPC](/guides/json-rpc): For an Application to communicate with the Ethereum network, it needs to establish a connection to an Ethereum Node, and be able to send and receive messages in a standardized format.
- [Mnemonics](/guides/mnemonics): A [BIP-39 mnemonic phrase](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki) is a list of words that is a representation of a seed, which can be used to derive the keys of a [BIP-32 Hierarchical Deterministic (HD) Wallet](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki).
- [Recursive Length Prefix (RLP)](/guides/rlp): The Recursive Length Prefix algorithm is a serialization method used extensively in the Ethereum protocol. RLP is a standard that aims to define a space-efficient approach to packaging and transferring arbitrary data.
- [Signed & Typed Data](/guides/signed-data): The [ERC-191 Signed Data](https://eips.ethereum.org/EIPS/eip-191) standard defines a specification for handling signed data in Ethereum contracts.
By defining a structured format for signable data, ERC-191 helps prevent vulnerabilities associated with obscured transaction signing and multi-signature wallets.
- [Sign-In With Ethereum (SIWE)](/guides/siwe): **Sign-In with Ethereum (SIWE)** is a standard described by [EIP-4361](https://eips.ethereum.org/EIPS/eip-4361) for how Ethereum accounts authenticate with off-chain services by signing a standard message format. This guide details how to perform SIWE with Ox in a client-server architecture.
- [Transaction Envelopes](/guides/transaction-envelopes): A Transaction Envelope is a structure that defines the properties of a transaction, and is generally
utilized to construct Transactions to be broadcast to a network.
- [WebAuthn Signers](/guides/webauthn): The [Web Authentication API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Authentication_API) contains a number of different credential types, including a credential with support for the P256 curve. This means that you can use WebAuthn-enabled authenticators like a [Passkey](https://passkeys.dev) or a [Yubikey](https://en.wikipedia.org/wiki/YubiKey) to sign transactions and arbitrary payloads.
