A template project for developing Xahau Hooks. Write hooks in C language, compile them to WASM, and execute them on the Xahau network.

This template provides a basic setup for developing and testing Xahau Hooks. The current hook implementation is a simple example that accepts all transactions.

• Node.js 18 or higher
• pnpm
• Docker
• xrpld-netgen
  • pip install xrpld-netgen

Install dependencies:

pnpm install

Compile C language source code to WASM:

pnpm build

The compiled WASM file will be output to build/index.wasm.

Run hook tests:

pnpm test

Tests will automatically compile the hook and deploy it on a local Xahau network for execution.

Start a local Xahau network using xrpld-netgen:

pnpm xrpld:start

Stop the local Xahau network:

pnpm xrpld:stop

View hook execution logs in real-time:

pnpm trace
