-# @pezkuwi/wasm
+# @pezkuwi/wasm-crypto
 
-Various WASM wrappers around Rust crates
+WASM cryptographic primitives for PezkuwiChain.
 
-## overview
+## Overview
 
-It is split up into a number of internal packages, namely utilities -
+This package provides WebAssembly-based cryptographic functions used by PezkuwiChain applications, including:
 
-- [wasm-crypto](packages/wasm-crypto/) Various hashing functions, sr25519 & ed25519 crypto
+- **SR25519** - Schnorr signatures with Ristretto point compression (bizinikiwi signing context)
+- **ED25519** - Edwards-curve Digital Signature Algorithm
+- **BIP39** - Mnemonic code for generating deterministic keys
+- **Hashing** - Blake2b, SHA256, SHA512, Keccak, XXHash, Scrypt, PBKDF2
 
-These are split from the `pezkuwi/util` repo where it is heavily used as part of `@pezkuwi/util-crypto`. (There JS fallbacks are available for some interfaces, e.g. hashing, but for sr25519 WASM is the only interface). Since these don't undergo massive changes on a daily basis and has a build overhead (WASM compilation & optimisation), it is better managed as a seperate repo with a specific CI configuration.
+## Installation
 
-## development
+```bash
+npm install @pezkuwi/wasm-crypto
+# or
+yarn add @pezkuwi/wasm-crypto
+```
 
-Contributions are welcome!
+## Usage
 
-To start off, this repo (along with others in the [@pezkuwichain](https://github.com/pezkuwichain/) family) uses yarn workspaces to organise the code. As such, after cloning, its dependencies _should_ be installed via `yarn`, not via npm; the latter will result in broken dependencies.
+```javascript
+import { waitReady, sr25519KeypairFromSeed, sr25519Sign } from '@pezkuwi/wasm-crypto';
+
+// Initialize WASM
+await waitReady();
+
+// Generate keypair from seed
+const seed = new Uint8Array(32); // your seed here
+const keypair = sr25519KeypairFromSeed(seed);
+
+// Sign a message
+const publicKey = keypair.slice(64);
+const secretKey = keypair.slice(0, 64);
+const message = new TextEncoder().encode('Hello PezkuwiChain!');
+const signature = sr25519Sign(publicKey, secretKey, message);
+```
+
+## Packages
+
+| Package | Description |
+|---------|-------------|
+| `@pezkuwi/wasm-crypto` | Main package with all crypto functions |
+| `@pezkuwi/wasm-crypto-wasm` | Compiled WASM binary |
+| `@pezkuwi/wasm-crypto-asmjs` | ASM.js fallback for older browsers |
+| `@pezkuwi/wasm-crypto-init` | Initialization helpers |
+| `@pezkuwi/wasm-bridge` | WASM bridge utilities |
+| `@pezkuwi/wasm-util` | Utility functions |
+
+## Building from Source
+
+```bash
+# Install dependencies
+yarn install
+
+# Build WASM and JavaScript
+yarn build
+
+# Run tests
+yarn test
+```
+
+### Prerequisites
+
+- Node.js 18+
+- Rust toolchain (for WASM compilation)
+- wasm-pack
+
+## Signing Context
+
+This package uses **bizinikiwi** as the SR25519 signing context, which is unique to PezkuwiChain. This ensures signature incompatibility with other networks for security.
