Use Cases

• Immediate disaster relief & prevention 🔥
• Tracking the efficacy of carbon credit providers 🌳
• Carbon offset tokens with built-in credit quality assurance 🛰

Technical Overview

For Storage (of the satellite imagery & other NFT data):

• We use IPFS & IPNS ¹ for storage (decentralized storage) & Pinata ² for updating the folders (CIDs) of the NFT metadata (embedded information) & satellite imagery stored.

For the Smart Contracts:

• Our NFT smart contracts use the ERC-721A protocol ³, which allows for low-cost (gas-fee) bulk minting.
• We also use the ERC-1155: Multi Token Standard, as it makes it simpler to create several different collections under one smart contract by allowing the minting of different tokens with unique BaseURIs—metadata). ⁴
• We have deployed several pre-audited ERC-1155 templates from Dedaub contract library. ⁵

For the UI:

• Our public mint page is built with React using Chakra-UI. ⁶

About Harberger Tax

• We have successfully deployed a Harberger Tax Implementation on Avalanche. (Modeled after WildCards ⁷)
• Originally deployed on Goerli Ethereum Test Network ⁸, we deployed our version on FUJI.
• Used for “taxing” NFT holders; holders have to pay to keep holding an NFT. ⁹
• This allowed us to implement a subscription-based NFT.
