Everything we claim is designed to be independently verifiable — by humans and by machines.
Our Model
This is the complete fund flow. Every step is designed to be auditable.
ZEV City earns standard affiliate commissions from travel booking partners (e.g., Trip.com, Trainline). Commission rates range from 3-8% depending on product type. Users pay the same price as booking directly.
100% of net commissions (after operating costs) are allocated to clean energy investment. Operating costs are funded separately through service fees and grants.
Funds are invested in local solar and wind projects in the regions where users travel. Each project is identified by specific asset IDs, location, and capacity.
Each user's contribution is tokenized on-chain, representing proportional ownership of energy production capacity. 80% of energy yield returns to token holders over the project lifetime (~20 years). The remaining 20% covers maintenance and reinvestment.
Verification
Our full contract suite is deployed on Ethereum Sepolia testnet. Mainnet deployment with initial energy fund backing is planned for Q2 2026. All contracts are open-source and independently auditable.
Contract Architecture: 8 interconnected contracts managing the complete lifecycle from booking → commission capture → energy asset tokenization → yield distribution → governance.
Core Token Contracts:
ZGBP Token (zGBP): 0xA75f7669492B6c1CdF01E35f39884f037F7Da262
pZGBP Token (Promised): 0x9df2589d79C0FF33AD118B1A05351e0EB810a273
zGBP represents verified energy asset value backed by real renewable energy production. pZGBP (Promised zGBP) represents pending energy assets from bookings not yet converted to operational energy infrastructure.
Infrastructure Contracts:
BookingManager: 0xb8A851bB56097b9B6C8AEffF82d5Ea260B04896B
EnergyAssetRegistry: 0x1Ec21aCB549741e978C2aaa719B8De15e3DCF8a9
AirdropPool: 0x64d6F2D9406CBDF317F83177FDc64cB455A3DAb0
RedemptionPool: 0xDec66F9166F0A33Eb6A333Df40541D0E66AB85Dc
BookingManager records travel bookings and calculates commission allocation. EnergyAssetRegistry tracks physical energy projects (solar panels, wind turbines) with location, capacity, and production data. AirdropPool distributes energy tokens to users. RedemptionPool handles conversion of energy tokens to real value.
Governance & Security:
GovernanceVoting: 0x15C89C1BB40aA9de71656546f7fc4E9619C957c6
ZEVTimeLock: 0x87570D4465170423879B3512aF71556399e3a144
Multi-sig Wallet: 0xCe52abA025d1AF9d53f79a43CF7CDD0edEB109Ec
GovernanceVoting enables token holders to vote on energy project decisions. ZEVTimeLock enforces time delays on critical operations for security. All admin functions require multi-signature approval.

This is the exact logic encoded in our smart contracts. Every step is verifiable:
1. User books travel via ZEV City
→ BookingManager records booking + commission amount
2. Commission received from affiliate partner (e.g., Trip.com)
→ Funds deposited to multi-sig wallet
→ pZGBP (Promised tokens) minted to user
3. Funds invested in energy project
→ EnergyAssetRegistry updated with project details
→ (location, capacity, installation date, meter ID)
4. Energy project begins producing
→ pZGBP converted to zGBP (verified energy tokens)
→ User now holds real energy asset ownership
5. Energy yields generated over project lifetime (~20 years)
→ 80% distributed to zGBP holders via RedemptionPool
→ 20% reinvested in maintenance + new projects
6. Governance decisions (new projects, policy changes)
→ GovernanceVoting: token holders vote
→ ZEVTimeLock: 48h delay on execution for safety
