Deployment

This document explains how CeloHT applications, smart contracts, and supporting services are deployed across development, testing, and production environments.

---

Overview

CeloHT follows a secure and automated deployment workflow to ensure reliability, transparency, and reproducibility.

Deployment includes:

• Web Application
• Smart Contracts
• Backend Services
• Documentation
• APIs

---

Deployment Environments

Environment	Purpose
Development	Local development
Staging	Internal testing
Testnet	Public testing on Alfajores
Production	Celo Mainnet

Requirements

Before deploying:

• All tests pass
• Linting passes
• Documentation is updated
• Security review completed
• Version number updated
• Changelog updated

---

Build Application

npm install

npm run build

---

Deploy Web Application

Example:

npm run deploy

Recommended hosting providers:

• Vercel
• Netlify
• Cloudflare Pages

---

Deploy Smart Contracts

Compile:

npx hardhat compile

Run tests:

npx hardhat test

Deploy to Alfajores:

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

Deploy to Mainnet:

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

---

Verify Contracts

After deployment:

npx hardhat verify CONTRACT_ADDRESS

Verification should always be completed before announcing a production release.

---

Environment Variables

Example:

NEXT_PUBLIC_NETWORK=celo

NEXT_PUBLIC_RPC_URL=https://forno.celo.org

NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID=YOUR_PROJECT_ID

DATABASE_URL=YOUR_DATABASE_URL

Never commit secrets to the repository.

---

Continuous Integration

Every deployment should automatically execute:

• Install dependencies
• Type checking
• Linting
• Unit tests
• Build verification
• Security scanning

---

Continuous Deployment

Production deployments should occur only after:

• Approved pull request
• Successful CI pipeline
• Required maintainer approval

---

Rollback Strategy

If a deployment fails:

1. Stop new deployments.
2. Restore the previous stable version.
3. Investigate the issue.
4. Fix the problem.
5. Redeploy after verification.

Every rollback should be documented.

---

Release Checklist

Before every production release:

• Documentation updated
• CHANGELOG updated
• Version tagged
• Tests passed
• Contracts verified
• Backup completed
• Security review completed

---

Monitoring

Production systems should be monitored for:

• Availability
• Performance
• Error rates
• API response times
• Blockchain synchronization
• Smart contract events

---

Disaster Recovery

If production becomes unavailable:

• Restore backups
• Redeploy infrastructure
• Verify data integrity
• Notify the community
• Publish an incident report

---

Deployment Principles

Every deployment must be:

• Reproducible
• Secure
• Transparent
• Auditable
• Automated
• Well documented

---

Future Improvements

Planned deployment enhancements include:

• Blue-Green Deployments
• Canary Releases
• Zero-Downtime Deployments
• Multi-region Infrastructure
• Infrastructure as Code
• Automated Security Audits
• AI-assisted Deployment Validation

---

Conclusion

Reliable deployments are essential to maintaining trust in the CeloHT ecosystem.

Every release should prioritize security, stability, transparency, and the long-term sustainability of the project.
