## Overview
Ox (⦻) is the foundation of robust Ethereum software written in TypeScript. It is an Ethereum Standard Library that provides a set of lightweight, performant, and type-safe TypeScript modules for Ethereum.
It offers core utilities & types for primitives such as: ABIs, Addresses, Blocks, Bytes, ECDSA, Hex, JSON-RPC, RLP, Signing & Signatures, Transaction Envelopes, and more.
As an unopinionated Standard Library, it is designed to be used by higher-level consumers (such as [Viem](https://viem.sh), [Tevm](https://tevm.sh), or their alternatives) to provide their own opinionated interfaces, and/or when reaching for low-level primitives may be needed without buying into a Client Abstraction stack (Viem, Ethers, Web3.js, etc).
## Documentation
[Head to the documentation](https://oxlib.sh) to read and learn more about Ox.
## Example Usage
The example below demonstrates how to construct, sign, and broadcast a transaction envelope using Ox:
```ts
import { Provider, Secp256k1, TransactionEnvelopeEip1559, Value } from 'ox'
// 1. Construct a transaction envelope.
const envelope = TransactionEnvelopeEip1559.from({
chainId: 1,
gas: 21000n,
nonce: 0n,
maxFeePerGas: Value.fromGwei('10'),
maxPriorityFeePerGas: Value.fromGwei('1'),
to: '0x70997970c51812dc3a010c7d01b50e0d17dc79c8',
value: Value.fromEther('1'),
})
// 2. Get the signing payload for the envelope.
const payload = TransactionEnvelopeEip1559.getSignPayload(envelope)
// 3. Sign the payload with your private key using secp256k1.
const signature = Secp256k1.sign({ payload, privateKey: '0x...' })
// 4. Serialize the envelope with the signature.
const serialized = TransactionEnvelopeEip1559.serialize(envelope, { signature })
// 5. Broadcast the envelope to the network.
const provider = Provider.from(window.ethereum)
const hash = await provider.request({
method: 'eth_sendRawTransaction',
params: [serialized],
})
```
> [!NOTE]
> Ox's APIs are purposely stateless, unopinionated, and verbose. The example above can definitely be achieved in a few lines of code in a more concise manner, however, the goal is for higher-level abstractions (Viem, etc) built on top of Ox to handle this for you.
