Build composable, upgradeable, secure Smart Contracts.
Build frontends that interact easily with (your own or anyone's) Smart Contracts.
Focus on the important parts of your Soroban app. Let Loam handle the tedious bits.
At a high level, Loam is comprised of three main components:
- Loam SDK - The Software Development Kit (SDK) are for writing smart contracts by creating and assembling subcontracts. Think of subcontracts as lego blocks you can snap together into a more complex whole. Currently, the SDK is focused on Stellar/Soroban smart contracts, but the subcontract pattern can be made to work with other blockchains as well.
- Loam Frontend - Modern frontend tooling paired with declarative environment configurations to help with local, test, and live blockchain networks.
- Loam CLI - Command Line Interface (CLI) for building smart contracts authored with Loam SDK. It's also for easily working with smart contract dependencies in a Loam frontend.
This project is a monorepo containing code primarily for Loam SDK but also for Loam CLI, both of which share build code.
What's in ./crates?
Organized hierarchically:
- Loam SDK - Tool for creating subcontracts.
- loam-subcontract-core - The most basic and essential subcontract, which manages admin/ownership and redeployability.
- loam-sdk-macro - Code for the
#[subcontract]macro to create your own brand new subcontract, if existing subcontracts do not suffice.
- Loam CLI - Build smart contracts authored with Loam SDK, manage smart contract dependencies from a frontend, initialize new loam projects
- loam-build - Used by CLI and SDK to look at dependencies and build contracts in the correct order.
- loam-soroban-sdk – This is a wrapper around soroban-sdk that extends it with features needed by Loam SDK.
- loam-subcontract-ft: like
loam-subcontract-coreabove, this contains the source code for a subcontract. This subcontract is mostly in this repository as an example; see below.
