Treejer protocol and its smart contracts:

  1. Manage payment and fund distribution from funders to rural planters and other stakeholders.

  2. Tokenize each planted tree using Ethereum's ERC-721 standard.

In other words, trees become non-fungible tokens with their stories recorded on blockchain. Information like tree funder, planter and status is a part of this story. This brings an unprecedented transparency to reforestation and lays the foundation for further calculation and tokenization of the impact.3) Calculate the impact and give immutable credit to contributors. This credit is called O2 (Oxygen).O2 is a blockchain-based carbon-credit supplied from Treejer trees and offered in Treejer’s voluntary market. It’s an ERC-20 token and is periodically minted and distributed to certain contributors (mainly funders) as trees grow and their existence is proved by the protocol. It brings decentralized carbon-credits to Ethereum and DeFi, unlocking new opportunities like carbon offsetting for Dapps and individual transactions.
