# Initiate Bridge To start the bridging process, you will need to use the Carbovalent DAPP to mint a non-fungible token (NFT), a carbon reference NFT. As of right now, the reference NFT is initialized as an empty state and lacks any carbon offset-related metadata. However, every NFT has a unique token address, which will be used as a verifiable link between the carbon credits and non-fungible tokens. As mentioned earlier, a reference NFT is required for each project and vintage of carbon credits that are retired in the source registry. Hence, the person conducting the bridging process may need to mint multiple reference NFTs, along with supplying multiple NFT token addresses in the retirement notes on the source registry. After retiring the carbon offsets on a registry, a permanent link between the retirement event and the NFT will be solidified by the information provided in the Retirement Details. The source registry account owner must provide: 1. **Carbon Credit Owner,** a Solana wallet address that was used to mint the reference NFT. 2. The **token address** of the reference NFT used for this specific retirement event. (Make sure the credits are of the same project and vintage) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
