Project Description

Nobrac creates accessibility towards the carbon credit market with a web2/web3 interface. The carbon credit market has become accessible through the toucan protocol that has issued 1 to 1 carbon credits that are in the institutional carbon credit market. To help users understand their carbon emissions we implemented a calculator that provides an estimate of how much carbon they emit in tonnes. With this information they can buy the equivalent carbon credits to offset their emissions. To abstract away web3 technology we allow web2 users to make account with their gmail and a wallet address is then tied to their gmail account. To purchase and retire these carbon credits, account abstraction is done to batch together the purchase, swap, and retirement of carbon credits. For those that are web3 native and retire a lot of carbon credits, they can appear on the leaderboard with updates powered by the graph. Those on the top 10 are given a button to mint an nft commemorating their achievement offsetting the most amount of carbon and establishing their carbon neutrality.

How it's Made

We used unlimit to onramp users with their credit cards and attempted to use their account abstraction. We used ens to resolve addresses to their ens name on the leaderboard. We used the graph to query the toucan contract that retires nfts to get the accounts with the most retired carbon credits. We used unlock to make the nfts that are uploaded onto decentralized storage. The celo and polygon blockchains were the blockchains interacted with because toucan protocol established their carbon credits on their applications. We used the nouns ip to create the images of the nfts.

ENS, the graph, unlock, allowed for the web3 integrations we were looking for without scaring away web2 native users.

Unlimit is the onramp we can use to bypass the web3 workflows to make it accessible to web2 native folk.
