CeloHT is a community-driven Web3 ecosystem built on the Celo blockchain, designed to combine financial inclusion, blockchain education, decentralized financial services, and environmental impact.
The architecture is modular. Each major component has a specific responsibility while remaining connected through the Celo network, community governance, and shared infrastructure.

CeloHT follows several core architectural principles:
CeloHT is designed around community participation rather than centralized decision-making.
Education, financial services, agent operations, environmental programs, and digital infrastructure are separated into logical modules.
Financial transactions and decentralized services use the Celo blockchain infrastructure.
CeloHT does not depend on issuing a proprietary speculative token. The ecosystem uses existing Celo-network assets such as CELO and cUSD where appropriate.
Core documentation, software components, governance rules, and development processes are intended to remain publicly auditable.
Technology is used to support measurable outcomes in financial inclusion, education, community development, and environmental restoration.
CeloHT can be understood as six interconnected layers.

├──────────────────────────────────────────────────────┤
│ 1. GOVERNANCE & TRUST LAYER │
│ Community • Policies • Treasury • Transparency │
└──────────────────────────────────────────────────────┘
The governance layer establishes how CeloHT operates as a community-driven ecosystem.
It includes:
Community participation
Governance proposals
Working groups
Treasury management
Conflict-of-interest rules
Financial transparency
Contribution policies
Security policies
Community decision-making
Governance is documented separately in:
GOVERNANCE.mdFUNDING_POLICY.mdSECURITY.mdCONTRIBUTING.mdLEGAL_STATUS.mdNO_TOKEN_POLICY.md
The architecture intentionally separates governance from application code so that organizational rules do not depend directly on a particular software implementation.
The blockchain layer is based on the Celo network.
Celo provides the underlying decentralized infrastructure for blockchain transactions and smart-contract functionality.
Primary assets used by the ecosystem include:
Used primarily for:
Network transaction fees
Blockchain operations
Ecosystem participation
Used where appropriate for:
Payments
Transfers
Financial inclusion activities
Community transactions
CeloHT does not require a proprietary token to operate.
Wallets provide the interface between users and blockchain-based financial services.
The primary wallet environment associated with CeloHT is Valora.

Wallet integrations are responsible for:
Transaction authorization
Address management
Sending assets
Receiving assets
Displaying balances
Signing blockchain transactions
CeloHT applications should never require users to expose private keys or seed phrases.
The Agent Network is a decentralized service layer designed to connect blockchain-based financial services with communities that may require physical or local access.
Agents can facilitate services such as:
Cash-in
Cash-out
Community transfers
Remittance-related services
User onboarding
Blockchain education
Basic wallet assistance

The agent network acts as a bridge between decentralized financial infrastructure and real-world community access.
Education is a core component of CeloHT.
The education layer is designed to reduce barriers to blockchain and digital-finance adoption.
Educational topics may include:
Financial literacy
Blockchain fundamentals
Web3
Celo ecosystem
CELO
cUSD
Digital wallets
Valora
Digital security
Responsible blockchain use
Community economic opportunities
The education layer connects directly to the agent network because trained users and agents can help communities understand and use decentralized financial tools.
The Rebwazman / Reforestation component connects digital-finance activity with measurable environmental impact.
The program can support:
Tree planting
Seedling acquisition
Fertilizer and agricultural inputs
Community participation
Environmental education
Impact tracking

Environmental Impact
This layer gives CeloHT an impact dimension beyond financial technology.
The application layer contains the user-facing software components of the ecosystem.
Potential components include:
CeloHT website
CeloHT dApp
Educational applications
Agent interfaces
Community dashboards
Investor and partner resources
Digital documentation
The application layer should remain modular so that individual applications can evolve without requiring the entire ecosystem to be rewritten.
Where blockchain automation is required, CeloHT can use smart contracts deployed on the Celo network.
A conceptual contract architecture is:

Smart contracts should follow security best practices and should be independently identifiable through their deployed contract addresses.
Where applicable, contracts should provide:
Source-code verification
Clear ownership information
Documented permissions
Events
Transaction transparency
Security documentation
Testing
CeloHT's treasury is conceptually separated from application logic.

Treasury management should be governed by documented policies rather than informal individual control.

Security is a cross-cutting concern across every layer.

Blockchain Security
Security practices include:
Private-key protection
Wallet security education
Least-privilege access
Secure environment variables
Dependency management
Automated testing
Code review
CI/CD security checks
Smart-contract verification
Vulnerability reporting
Security policies should be documented in SECURITY.md.
CeloHT uses different categories of information and should avoid treating blockchain data and application data as the same thing.
Examples:
Wallet addresses
Blockchain transactions
Smart-contract events
Transaction hashes
Blockchain balances
Examples:
Educational records
Community information
Program administration
Application configuration
Public documentation
Examples:
Number of people trained
Number of transactions
Agent activity
Trees planted
Community participation
Program outcomes
Sensitive personal information should not be unnecessarily stored on-chain.
The CeloHT ecosystem is organized across multiple repositories according to functionality.
Representative repositories include:
Celo-HaiTi/
│
├── celoht-dapp
├── CeloHT-Platform
├── CeloHT-ValoraApp
├── CeloHT-EduAgentForest
├── celoht-education
├── celoht-ngo-platform
├── celoHT-website
├── celoht-brand
└── celoht-investor-deck
The exact repository structure may evolve as the project grows.
The objective is to keep application code, documentation, branding, education, and specialized products sufficiently separated to allow independent development.
CeloHT can integrate with external infrastructure where necessary.
Potential integration categories include:
Integration | Purpose -- | -- Celo | Blockchain infrastructure Valora | Wallet and payment interaction Block explorers | Transaction and contract verification GitHub | Source code and collaboration Web hosting | Public applications APIs | External data and service integration Analytics | Impact and operational measurementCeloHT is architected as a community-driven, modular Web3 ecosystem rather than as a single application.
Its architecture connects:
Community → Education → Wallets → Agents → Celo Blockchain → Financial Services → Environmental Impact
The technical foundation is provided by the Celo network, while CeloHT adds application, education, agent, governance, and impact layers around that infrastructure.
The architecture is intentionally modular so that individual products, applications, and services can evolve independently while remaining part of the broader CeloHT ecosystem.
