+The encoding of the value depends on the content type specified by the protoCode. Values with protocodes of 0xee and 0xef represent IPFS and Swarm content; these values are encoded as v1 [CIDs](https://github.com/multiformats/cid) without a base prefix, meaning their value is formatted as follows:

 ```
 
 When resolving a `contenthash`, applications MUST use the protocol code to determine what type of address is encoded, and resolve the address appropriately for that protocol, if supported.
