# Prerequisites to Bridge

Carbon offsetting projects need to meet certain criteria in order for them to be verified on the Carbovalent Registry.

#### 1. Verified Carbon Units (VCUs) in the Verra/Gold Standard registry

You will need to have access to the registry account or a partner who has the authority to retire VCUs on your behalf, indicating that they are to be bridged on Carbovalent. Moreover, it is important to make sure that you are retiring carbon credits of the same vintage and project on the same reference NFT. Also, check this [section ](/bridge/morpheus-carbon-bridge/prerequisites-to-bridge/eligibility.md)out to see if your credits are eligible for bridging.   

*\~Failure in one of the steps could lead to a permanent loss of funds.*

#### 2. Solana Wallet

You need to have a Solana wallet (eg: [Phantom](https://phantom.app/)) as a browser extension (mobile coming soon). Also, you will need to have some Solana to pay for the gas fees, which is roughly 0.00025$ per transaction. It is also important to note that you cannot interact with the Carbovalent protocol through a centralized exchange. 

#### 3. Attention to detail

Bridging carbon credits to the Solana network is a permanent process, and errors could result in the permanent loss of Solana or carbon credits. Take your time and be cautious! We will update the documentation with detailed video tutorials on how to safely bridge your credits using the Carbovalent protocol.

**Excellent work! After you've completed all of the prerequisites, you can begin the bridging process.**
