Capminal Contracts

Open-source smart contracts powering the Capminal protocol — staking for the $CAP token and the CAPU compute-credit system that funds AI access on the Capminal LLM Gateway.

This is a Foundry monorepo. Each module lives under projects/ with its own foundry.toml, sources, and tests.

Module	Path	Summary
Cap Staking (deprecated)	projects/cap-staking	Retired. Lock-duration staking for $CAP with a 1×–5× share multiplier. Superseded by the CAPU Vault below — kept for reference only.
CAPU Vault	projects/capu	Two-token system: stake CAP → receive non-transferable sCAP → lock sCAP to mint CAPU, a compute asset granting $1/day of AI Credit. UUPS-upgradeable, with Synthetix-style streaming CAP rewards.

The $CAP token is deployed on Base mainnet at 0xbfa733702305280F066D470afDFA784fA70e2649.

Getting started

Install Foundry, then pull the Solidity dependencies (tracked as git submodules):

git clone --recurse-submodules https://github.com/Capminal/capminal-contracts.git
cd capminal-contracts
# if you already cloned without submodules:
git submodule update --init --recursive

Build & test

# Cap Staking
cd projects/cap-staking && forge build && forge test

# CAPU Vault
cd projects/capu && forge build && forge test

Dependencies (OpenZeppelin, OpenZeppelin Upgradeable, PRBMath, forge-std) are managed via Foundry git submodules under each project's lib/.

Security

These contracts are provided as-is. Always review the source and run your own tests before interacting with any deployment. See each module's README for detailed security notes.

Found a vulnerability? Please report it privately — see SECURITY.md — rather than opening a public issue.
