🧭 Roadmap: Smart Contract Developer – NairaX

 


🎯 Role Objective:

Design, build, audit, and maintain secure, scalable, and upgradeable smart contracts for minting, redemption, compliance, and reserve tracking of the NairaX stablecoin.

🗓️ 12-Month Roadmap by Phase

✅ Phase 1: Planning & Standards (Month 1–2)

Goal: Define the smart contract architecture and security framework.

TaskDeliverables
📘 Research- Study existing stablecoins (DAI, USDC, Celo Dollar, eNaira)
- Align with Nigeria’s blockchain & data privacy policy
🧠 Architecture- Define contract modules: NairaX Token, ReserveManager, Issuer, Compliance
📜 Token Standard- Decide on ERC-20 / ERC-677 / ERC-4626 (for savings)
- Consider upgradable contract patterns (OpenZeppelin’s UUPS or Proxy)
🔐 Security Guidelines- Create internal checklist: overflow protection, pausable contract, role-based access control
🧰 Tooling Setup- Choose Solidity, Hardhat/Foundry, Slither, MythX, GitHub workflows

✅ Phase 2: MVP Contract Development (Month 3–5)

Goal: Build and test the core contracts.

ModuleDeliverables
🪙 NairaXToken.sol- Mintable/burnable ERC-20 with pausable functionality
- KYC-only transfers (whitelist enforcement)
🧾 ReserveManager.sol- Link between fiat reserves and tokens in circulation
- Track off-chain reserve IDs + hash proofs
🏛️ IssuerAgent.sol- Agent contract for authorized mint/redemption partners
- Role-based access (admin, issuer, auditor)
👮 ComplianceProxy.sol- Integrate with external KYC system
- Revoke address, freeze accounts
🧪 Tests- 80–100% unit test coverage using Hardhat/Foundry
🔄 Mocks- Mock off-chain reserve and bank integration
📊 Events- Emit logs for mint, burn, reserve updates

✅ Phase 3: Audit & Testnet Launch (Month 6–7)

Goal: Finalize security and deploy on testnet.

TaskDeliverables
🛡️ Internal Audit- Manual audit of logic, modifiers, and storage layout
🧪 Testnet Deployment- Deploy to Goerli, Sepolia, or AfriChain testnet
🧠 Simulation- Run gas optimization, exploit scenarios, role escalation
🔍 External Audit Prep- Freeze v1.0 contracts for formal audit (Certik, Hacken, OpenZeppelin)
📚 Documentation- Full function descriptions, usage, and diagrams

✅ Phase 4: Mainnet Launch & Monitoring (Month 8–9)

Goal: Deploy to mainnet and integrate with frontends.

TaskDeliverables
🚀 Mainnet Deployment- NairaXToken, ReserveManager, IssuerAgent deployed with admin keys
🔑 Multisig Governance- Gnosis Safe for mint/burn roles and upgrades
🖥️ Integration- Connect with web wallet, admin dashboard
📡 Analytics- Dune Dashboard: Circulating Supply, Mint Volume, Redemptions
🛠️ Scripts- Admin scripts: pause, freeze, mint, burn, upgrade

✅ Phase 5: Upgrades & Interoperability (Month 10–12)

Goal: Prepare for scalability, DeFi integrations, and DAO governance.

TaskDeliverables
⚙️ Upgradeability- Implement upgrade-safe patterns (UUPS or Diamond Standard)
🌍 Cross-Chain Bridge- Integrate with LayerZero, Wormhole, or Chainlink CCIP
🧑‍⚖️ DAO Preparation- Role transfer to governance contracts for decentralization
💸 NairaX Savings- Add ERC-4626 Vaults or interest-bearing wrappers
🤝 DeFi Ready- Audit for lending protocols, AMMs, or staking integrations

🛠️ Recommended Stack

CategoryTools
LanguageSolidity, Vyper (optional)
FrameworkHardhat, Foundry
AuditingSlither, MythX, Surya, Certik, OpenZeppelin Defender
TestingChai, Waffle, Anvil, Forge
DeploymentAlchemy, Infura, or AfriChain RPC
GovernanceGnosis Safe, OpenZeppelin Governor
MonitoringTenderly, Etherscan, Dune Analytics, The Graph

🔐 Best Practices to Follow

  • Use OpenZeppelin libraries (ERC20, Ownable, AccessControl)

  • Implement require() checks with clear error messages

  • Role separation: Admin vs Issuer vs Auditor

  • Avoid tx.origin, use msg.sender

  • Gas-optimized code: pack storage, avoid redundant calls

  • Maintain upgrade logs and changelogs

📊 Metrics to Track

MetricPurpose
totalSupply() vs Reserve balancePeg assurance
Mint/burn volumeMarket activity
Address blacklist/freeze countCompliance stats
Function gas costsOptimization & L2 planning
Time-to-upgrade (TTU)Governance agility
