Bridge

The Carbon Bridge allows anyone to bring their carbon credits from legacy registries onto the Buckmint Registry.

This section includes an overview on the Carbon Bridge, requirements to successfully bridge, and step-by-step instructions on how to bridge carbon from the Verra registry: initialize, retire, submit, and await approval and finally fractionalize to fungible BCO2 Buckmint carbon credits.

The Buckmint Carbon Bridge

The Carbon Bridge allows anybody to bring their carbon credits on-chain in a tokenized form. Tokens have multiple advantages over legacy credits, including full transparency, programmability, fractionalization, and composability with the emerging DeFi ecosystem. We want tokenized carbon to become a new DeFi primitive—a carbon money lego.

For now, the Carbon Bridge connects legacy carbon registries with the Buckmint Registry, an on-chain registry on the Polygon network. We believe that carbon needs to be a multi-chain asset, and more public blockchains will be supported in the future.

How it works

The Buckmint Carbon Bridge is a two-way bridge: carbon credits can be brought on-chain and off-chain. The reason for that is simple: we want to prevent double-counting and value the deterministic nature of public blockchains. After all, a public blockchain is probably a safer and more transparent way to keep track of carbon assets than any centralized ledger system 🤷
