GrantedAccountAccess

1// MADE BY: Emerald City, Jacob Tucker
2
3// This is a very simple contract that lets users add addresses
4// to an "Info" resource signifying they want them to share their account.  
5
6// This is specifically used by the
7// `pub fun borrowSharedRef(fromHost: Address): &FLOATEvents`
8// function inside FLOAT.cdc to give users access to someone elses
9// FLOATEvents if they are on this shared list.
10
11// This contract is my way of saying I hate private capabilities, so I
12// implemented an alternative solution to private access.
