Follower System

The LSP26 Follower System provides a standardized way to manage social connections on-chain. This guide will help you understand how to interact with the LSP26 contract.

Interacting with the LSP26 - Follower System Contract

Following an Address

To follow an address, call the follow function:

function follow(address addr) external;

Example usage:

await followerSystemContract.follow(addressToFollow);

Unfollowing an Address

To unfollow an address, use the unfollow function:

function unfollow(address addr) external;

Example usage:

await followerSystemContract.unfollow(addressToUnfollow);

Checking Follow Status

To check if one address is following another:

function isFollowing(address follower, address addr) external view returns (bool);

Example usage:

const isFollowing = await followerSystemContract.isFollowing(
  followerAddress,
  followedAddress,
);

Retrieving Follower and Following Counts

To get the number of followers or followed addresses:

function followerCount(address addr) external view returns (uint256);
function followingCount(address addr) external view returns (uint256);

Example usage:

const followers = await followerSystemContract.followerCount(address);
const following = await followerSystemContract.followingCount(address);

Best Practices

1. Batch Operations: For following or unfollowing multiple addresses at once, use the followBatch and unfollowBatch functions to save on gas costs.

2. Pagination: When retrieving large lists of followers or following, use the paginated getFollowersByIndex and getFollowsByIndex functions to avoid gas limits and improve performance.

3. Event Listening: Set up event listeners for the Follow and Unfollow events to keep your dApp's state in sync with on-chain changes.

4. LSP1 Integration: If your dApp interacts with LSP1-compatible contracts, be prepared to handle the LSP26 follow/unfollow notifications through the universalReceiver function.
