# 4.2 Project Management

Efficiently running your dApp from idea → launch → maintenance is essential. GRX Chain provides EVM-compatible building blocks and clear patterns so teams can manage code, keys, releases, and governance with confidence.

### What this section covers

* Secure smart-contract lifecycle (deploy, verify, upgrade)
* Treasury & admin safety (multi-sig, timelocks, roles)
* Monitoring & cost control (gas, volume, health)
* Funding transparency & auditability
* Integration with common dev workflows

### Recommended lifecycle (at a glance)

1. **Plan & threat model** → define roles, privileges, and upgrade policy
2. **Build** → write contracts/tests; pin compiler; static analysis & fuzzing
3. **Stage on testnet** → rehearsed deploys, seeded test data, attack sims
4. **Audit & remediate** → external review; fix & re-test; publish report
5. **Mainnet release** → deploy, verify on **GRXscan**, publish changelog
6. **Guardrails on** → multi-sig, timelock, least-privilege roles, pause (if disclosed)
7. **Observe & iterate** → dashboards, alerts, periodic key/role reviews, governed upgrades

### Smart-contract lifecycle management

* **Version control & determinism**\
  Pin Solidity compiler (exact version), lock dependencies, reproducible builds; archive ABIs/bytecode/source maps.
* **Upgrade patterns (EVM)**\
  Prefer **Transparent** or **UUPS** proxies. Document upgrade authority and runbook. Wrap upgrades with a **timelock** for review.
* **Verification & provenance**\
  Verify every contract on **GRXscan** (exact compiler + constructor args). Tag releases and link addresses in notes.
* **Release hygiene**\
  Use a limited-power **canary** before full cut-over. Maintain a deterministic **migration script** (Hardhat).

### Secure multi-signature & admin controls

* **Multi-sig for critical actions**\
  Treasury moves, parameter changes, upgrades → **M-of-N** approvals; publish signer addresses; use hardware wallets.
* **Timelocks & role scoping**\
  Route sensitive calls via **24–72h timelock**. Define minimal roles (`PAUSER`, `PARAM_SETTER`, `UPGRADER`) instead of a single super-admin.
* **Emergency posture**\
  If a pause/kill switch exists, disclose it clearly, time-bound it, and control via multi-sig.

### Monitoring, telemetry & cost control

* **On-chain metrics**\
  Tx success rate, revert reasons, events volume, unique wallets, TVL/LP depth (if DeFi), **gas per function**. Expose a public dashboard.
* **Gas & performance**\
  Log average `gasUsed` by function; set CI budgets; use **Multicall**; avoid unbounded loops; cache immutable config.
* **Alerts**\
  Spike in failed txs, unusual admin calls, role changes, liquidity outflows, oracle staleness, missed keeper jobs.

### Funding transparency & auditability

* Route grants/ops payments via **multi-sig**; label addresses on **GRXscan**.
* Publish a simple **treasury ledger** mapping transfers to proposals/issues.
* Reference governance IDs in payment memos; update status in forum/RFC threads.

### Integrating with developer workflows

* **Tooling**: Hardhat/Truffle + ethers.js/web3.js
* **Environments**:
  * Mainnet RPC: `https://rpc.grxchain.io` (Chain ID **1110**)
  * Testnet RPC: `https://testnet.grxchain.io` (Chain ID **2507**)
  * Explorers: `https://grxscan.io`, `https://testnet.grxscan.io`
* **Hardhat sample**

```js
export default {
  solidity: "0.8.24",
  networks: {
    grx: { url: "https://rpc.grxchain.io", chainId: 1110, accounts: [process.env.PRIVATE_KEY].filter(Boolean) },
    grxTestnet: { url: "https://testnet.grxchain.io", chainId: 2507, accounts: [process.env.PRIVATE_KEY].filter(Boolean) }
  }
}
```

## Release & Environments

* **Branches**: `main` (prod), `release/*` (staging), `dev/*` (feature)
* **Promotion flow**: `dev` → **testnet** → `release` → **mainnet**
* **Quality gates**: tests ≥ 95% pass; static analysis clean; gas diff within budget; audit items resolved
* **Freeze windows**: 24–72h before major releases; emergencies via timelocked multi-sig only

## Change Management (short)

* **Types**: standard (low risk), normal (reviewed), emergency (security/hotfix)
* **Artifacts**: PR + `CHANGELOG.md` + `UPGRADE.md` + Runbook link
* **Approvals**: ≥2 maintainers for contract changes; ≥M-of-N multi-sig for parameter changes
* **Post-deploy**: verify on GRXscan, publish addresses, tag release, announce risks

## Keys, Secrets & Signers

* **Storage**: hardware wallets (Ledger/Trezor/HSM); no hot keys for treasuries
* **Rotations**: quarterly or on incident; documented ceremony
* **Multi-sig defaults**: 2/3 ops; 3/5 treasury; 4/7 upgrades (adjust as needed)
* **Timelocks**: 24h params, 48–72h upgrades; emergency path documented & disclosed

## Rollback & Migration

* **Proxy upgrades**: keep prior impl address; run **health checks** before switching
* **State safety**: snapshot critical mappings before upgrades
* **Abort criteria**: error rate >2%, invariant breaks, oracle failure, liquidity drain
* **Revert plan**: switch proxy back, pause affected modules (if disclosed), postmortem within 7 days

## Oracles & External Dependencies

* **Checklist**: redundancy, staleness bounds, circuit breakers, fallbacks
* **Alerts**: price deviation, heartbeat miss, signature mismatch
* **Docs**: list providers, SLA hints, failure modes

## Licenses & Compliance

* **SBOM**: generate each release; pin compiler & deps
* **License policy**: prefer permissive OSS; record exceptions
* **Third-party reviews**: annual review of explorer/RPC/bridge providers

## Docs & Runbooks (add these to your repo)

* `SECURITY.md`: report path, scope, safe-harbor
* `RELEASE.md`: checklist + promotion steps
* `RUNBOOK.md`: deploy, rollback, pause, resume
* `UPGRADE.md`: proxy pattern, roles, timelock, tests
* `RISKREGISTER.md`: top risks + owners + mitigations

## RACI (who does what)

* **Core team**: roadmap, releases, incident comms
* **Maintainers**: reviews, merges, versioning
* **Security lead**: audits, bug bounty triage, IRP
* **Ops**: nodes, monitoring, backups
* **Comms**: changelog, user notices, deprecation comms

## Monitoring & SLOs

* **Golden signals**: tx success rate; median/p95 gas by function; block-time variance; mempool backlog
* **Business KPIs**: unique wallets, DAU, swaps/volume, TVL, retention
* **SLO (example)**: ≥99.5% successful txs; <2s median inclusion under normal load
* **Alerting**: page on SEV-1/2 only; make thresholds configurable
