Requirements to bridge
In order to bring carbon offsets over the Carbon Bridge onto the Toucan meta-registry, you'll need to have access to a few things:
- Carbon offsets in the Verra registry, along with a retirement account or a partner who can retire the offsets for you. If you are working with a partner, you MUST coordinate with them to properly do the bridging — failure to do so may result in irreversible loss of funds!
- An Ethereum account controlled by your Metamask wallet (browser extension, not mobile) with some MATIC, the native token that is required to pay for gas on the Polygon network. You cannot interact with the Toucan Protocol from a centralized exchange like Coinbase.
- Time and attention! Bridging is an irreversible action, and mistakes can lead to the permanent loss of funds / offsets. Take care, take your time. If you have any questions, study our docs or ask in our community-moderated Discord channel, #bridge-support.
The Toucan core team can't help with any of this, but there is a lot of community-led support in our Discord, and many resources online on setting up Metamask (back up your mnemonic!), getting MATIC and buying offsets from someone with a Verra account.
It is critical that you only include batches from the same project AND vintage in a single bridging event.
In Verra you have the option to retire offsets from different vintages in the same retirement. This behavior is not compatible with the Toucan Protocol — you must only retire offsets from the same project and vintage with each retirement.
If you have a partner who will be retiring on your behalf, work with them to learn how many different project-vintages they'll need to retire. You may need to initialize multiple batch NFTs and provide them with multiple Toucan IDs for different individual retirements.
We are not responsible for mistakes here! If in doubt, study more or do not engage with the protocol.
Once you've got all of these prepared, you can start the bridging process!
