**Heritage Guard:** A collateral-backed NFT and escrow system for rare plants.

Heritage Guard is a platform that allows farmers of rare plants to issue an NFT backed receipt to users who can burn the NFT to redeem the underlining collateral. When the user `mint()` the NFT, the funds is transfered to an escrow contract issued by a digital arbitrator in case of a dispute during the `claim()|burn()` process.

## Farm Feature

## Recommendations

- Fractional ownership.
- Auction Plant close to the end of the escrow period and ship to bidder.

## Risk

- Crypto Regulations
