Membership Contract Access

The membership contract is an opportunity to store data in a way that is not as traceable as NFT ownership. Unlike NFTS, the ownership of a membership contract is controlled by the contract owner and therefore cannot be transferred. In addition, relevant non-PII metadata can be stored in the entry for quick retrieval.

public func addMembership(_ contractAddress: String, _ userAddress: String, _ metadata: String) async 

This asynchronous function adds a membership to the given contract address for the given user Ethereum address and metadata. It gets the contract ABI (Application Binary Interface) using the 'getContractABI' function, constructs a contract instance, and then creates a transaction to call the 'addMembership' function with the given user address and metadata. It signs the transaction with the private key and then sends the transaction to the network to be mined.

Parameters:

removeMembership

public func removeMembership(_ contractAddress: String, _ userAddress: String) async 

For an existing member, this will revoke their membership, expunging the entry for future requests in the entry associated with the calling address.

Parameters:

checkMembership

public func checkMembership(_ contractAddress: String, _ ownerAddress: String, _ userAddress: String) async -> Bool 

Checks if a user is a confirmed member of a contract on the Ethereum blockchain.

Parameters:

[available from version 1.1]

getMembershipMetadata

public func getMembershipMetadata(address publisherAddress,address customerAddress)

For members, this method will retrieve the metadata that was stored by customerAddress associated with a member with the public key customerAddress. Like confirmMembership, this is accessible to all authorized callers as defined by the contract owner.

Parameters:
