Have you seen projects where metaverse property sells as NFTs, yet no one uses the map? Without a solid coordinate system, flexible rights, and a scarcity economy, the grid stays empty. Our team has built dozens of such systems – from simple 2D grids to full 3D worlds. Order a turnkey metaverse property system from on-chain logic to client rendering.
Problem Breakdown
Coordinate Storage
Packing coordinates into tokenId (int16 x, int16 y → uint32) limits world size to 65,536 x 65,536 but reduces gas costs by 40%. For larger worlds, use a separate mapping with bit-packing. Example: for a 2D grid, store (uint64 packed) where each 16 bits represent x, y, z, and an ID. This saves 50% storage versus a struct.
Adjacency Checks
On-chain O(n²) works for up to 30 parcels. For larger Estates, off-chain verification via Merkle proofs (gas cost: 20,000 gas per check) or ZK proofs (one-time 500,000 gas for 100 parcels). Implementation: Merkle tree of adjacent parcels; only root stored on-chain.
Rights Configuration
Landowners can set permissions: building, visiting, trading. Implemented as a bitmask: 1 bit per right. Example: uint8 rights = 0b00000111 (all rights). Gas cost: 5,000 for setting.

Comparator: On-Chain vs Off-Chain Coordinate Storage
| Aspect | On-Chain | Off-Chain (Merkle/Proof) |
|---|---|---|
| Gas cost per update | ~50,000 gas | ~10,000 gas (proof verification) |
| World size limit | 2^32 parcels | Unlimited |
| Trust model | Trustless | Requires off-chain indexer |
| Implementation complexity | Low | Medium |
FAQ
Q: How much does deployment cost? A: On Polygon, deploy and mint 10,000 parcels costs ~$500 in MATIC. On Ethereum, $5,000 in gas. Q: Can I integrate with existing metaverse platforms? A: Yes, we provide adapters for Decentraland, The Sandbox, and Somnium Space. Q: What is the royalty fee? A: We set EIP-2981 to 5% of secondary sales.
