🪙Internal Credit Registry

What we needed to support

Minting carbon removal credits needs to happen in a traceable way; we needed to be able to keep track of individual serialized credits and whether they had been delivered or retired. We also needed to be absolutely certain that we only minted one credit for every tonne of carbon removed.

What we built

A centralized Credit Registry for internal tracking of minted and delivered credits. The registry does automatic validation of the available balance of co2e from our ledger as well as making sure the deployments from which we are issuing credits have not been fully spent, i.e. that there is still balance available for the credits being minted.
