Returns a list of all the collection contracts you’ve previously deployed.
It can also return merkle proofs of all the whitelisted addresses with include set to merkle_proofs. These proofs can be used during presale/whitelisted minting.
A Merkle proof is a series of hashes which can be combined with the Merkle tree root and and the node (address) it was generated for, to verify that the node is contained in the Merkle tree without having access to the entire tree.

Useful for:

• Retrieving collection-specific contract details.
• Retrieving your collection contract creation history.
• Getting merkle proofs of whitelisted addresses.
