A Collection of Verbosely Document Huff Contracts.

Usage

Make sure you've installed the Huff Compiler as outlined in the Huff Docs.

TL;DR: curl -L get.huff.sh | bash && huffup

To verify your installation, run huffc --help. This should print a list of available commands for the huff compiler cli.

Steps

This is how to create the contract bytecode to output Hello, World! in Huff.

1. Create a file called hello-world.huff and enter the following content:

   #define macro MAIN() = takes (0) returns (0) {
       0x48656c6c6f2c20776f726c6421 0x00 mstore // Store "Hello, World!" in memory.
       0x1a 0x00 return // Return 26 bytes starting from memory pointer 0.
   }
   

2. Use huffc to compile the contract and output bytecode:

   huffc hello-world.huff --bytecode
   

   This will output something like:

   6100168061000d6000396000f36c48656c6c6f2c20776f726c6421600052601a6000f3
