E-Land was an early real-world-asset project I helped spearhead: we tokenized properties and sold percentage interests in them as fractional shares, well before RWAs became a category.
Each property was represented as an NFT and split into fractional shares using ERC-4675, the standard for multi-fractional NFTs. Owning shares meant owning a slice of a real building.
Decisions
Liquidity without debt
Fractional shares solved both sides of the market. Owners sold a percentage of a property and pulled out liquidity without taking on debt or selling the building. Investors bought into new projects for the price of a share, not the price of a building.
ERC-4675: one contract for every property
ERC-4675 manages many NFTs, each with its own fractional share supply, in a single contract. That mirrors the real world exactly: one property, one NFT, many owners, and one contract for the whole platform.
What I built
- A single ERC-4675 contract for all of E-Land. Every property lived in it as its own NFT with its own share supply, so listing a new building meant minting into the contract, not deploying a new one.
- Indexing of the contract, turning onchain share sales and ownership into data the frontend could show.
- Metadata management for each property's public page: percentage of shares sold, construction progress, and details about the property itself.
- A Next.js frontend hosted on Netlify, with wallet connection through WalletConnect and contract reads and writes with viem, so investors could connect a wallet and buy shares directly.
- Testnet and mainnet deployments running on QuickNode RPC.
