Smart Contracts

This document provides an overview of the smart contracts that power the CeloHT ecosystem.

Overview

CeloHT leverages smart contracts on the Celo blockchain to provide secure, transparent, and decentralized services. Every contract is designed with simplicity, security, and long-term maintainability in mind.

Design Principles

Every smart contract follows these principles:

  • Security First
  • Open Source
  • Transparency
  • Gas Efficiency
  • Upgradeability (when appropriate)
  • Community Governance
  • Audit Readiness

Technology Stack

  • Solidity
  • Hardhat
  • OpenZeppelin Contracts
  • Ethers.js
  • TypeScript
  • Foundry (future support)

Network Support

Mainnet

Network Status
Celo Mainnet Planned

Testnet

Core Contracts

Education Contract

Responsible for:

  • Course registration
  • Certificate verification
  • Learning records
  • Community achievements

Agent Network Contract

Responsible for:

  • Agent registration
  • Agent verification
  • Reputation system
  • Service status

Reforestation Contract

Responsible for:

  • Campaign registration
  • Tree planting records
  • Environmental impact tracking
  • Public transparency

Treasury Contract

Responsible for:

  • Community treasury
  • Fund allocation
  • Financial transparency
  • Governance-controlled spending

Governance Contract

Responsible for:

  • Proposal creation
  • Community voting
  • Decision execution
  • Governance records

Wallet Compatibility

Supported wallets include:

  • Valora
  • MetaMask (Celo Network)
  • Rainbow Wallet
  • WalletConnect-compatible wallets

Security Features

Contracts are developed following industry best practices:

  • Reentrancy protection
  • Access control
  • Pausable mechanisms
  • Overflow protection
  • Input validation
  • Emergency controls

OpenZeppelin security libraries are used whenever applicable.

Upgrade Strategy

When upgradeability is required, contracts should follow transparent governance procedures.

Critical upgrades must:

  • Be publicly announced
  • Be reviewed by maintainers
  • Be approved through governance (where applicable)

Testing

Before deployment, every contract should pass:

  • Unit Tests
  • Integration Tests
  • Gas Optimization Tests
  • Static Analysis
  • Security Checks

Example:

npm test

Coverage reports should be generated for every release.

Audits

Every production contract should undergo:

  • Internal review
  • Community review
  • Independent security audit (when feasible)

Audit reports will be published publicly to maintain transparency.

Deployment

Deployment scripts are located in:

scripts/

Example:

npx hardhat run scripts/deploy.ts --network alfajores

Verification

After deployment, contracts should be verified on the appropriate blockchain explorer.

Verification enables:

  • Public source code inspection
  • Improved transparency
  • Easier developer integration

Best Practices

Developers should:

  • Write modular contracts
  • Keep functions simple
  • Document all public methods
  • Minimize gas consumption
  • Avoid unnecessary complexity
  • Prioritize readability over cleverness

Future Roadmap

Planned improvements include:

  • DAO Governance
  • Community Treasury Automation
  • On-chain Certifications
  • Agent Reputation Scoring
  • Environmental Impact Verification
  • Multi-signature Treasury Management
  • Cross-project integrations within the Celo ecosystem

Disclaimer

Smart contracts are continuously improved as the CeloHT ecosystem evolves.

Community feedback, security reviews, and transparent development remain essential parts of the project's long-term success.
