Canto Identity Protocol SDK (CIP-SDK)

The Canto Identity Protocol SDK provides easy use functions to retrieving user CIP data.

Canto Identity Protocol

Canto Identity Protocol (CIP) is an on-chain identity protocol that aggregates identity from Subprotocols. Anyone can permissionlessly create a Subprotocol to represent any kind of identity trait – textual, visual, or otherwise. End users freely choose which traits to include in their on-chain identity.

Install

npm i cip-sdk

Example

import { ethers } from 'ethers';
import { CIP } from 'cip-sdk';

// Initialize provider and CIP instance
const provider = new ethers.JsonRpcProvider('<YOUR_CANTO_RPC_URL>');
const cipInstance = new CIP(provider);

// Retrieve user data using CIP
const namespace = await cipInstance.getNamespaceByAddress('<USER_CANTO_ADDRESS>');
const bio = await cipInstance.getBioByAddress('<USER_CANTO_ADDRESS>');
const pfp = await cipInstance.getPfpByAddress('<USER_CANTO_ADDRESS>');

Methods

• getCID(address): CID - returns the CIP NFT ID of the provided address.
• getPrimaryData(cid, subprotocolName): sub protocol CID - Method is used to get the users NFT IDs of any subprotocol registered with the user's CID.
• getNamespaceCID(cid): namespace CID - Method used to get the users registered namespace CID.
• getBioCID(cid): bio CID - Method used to get the user's registered bio CID.
• getPfpCID(cid): pfp CID - Method used to get the user's registered pfp CID.
• getNamespace(namespaceCID): Namespace - Method used to return te user's registered namespace display name and base name.
• getPfpData(pfpCID): ProfilePictureData - Method used to get the user's profile picture data from profile picture contract. Profile picture data = [nftContractAddress, nftID]
• getPfpImage(nftContractAddress, nftID): ProfilePictureInfo - Method used to get the user's pfp image data. return value will be src = image src, alt: nft name.
• getBio(bioCID): bio - Method used to get user's bio information. return value is a string of the registered bio.
• getBioByAddress(address): bio - Method is an aggregation of getCID, getBioCID and getBio. This method only needs user's address to return the bio.
• getNamespaceByAddress(address): Namespace - Method used to get user's namespace data. This method is also an aggregation of getCID, getNamespaceCID, and getNamespace.
• getPfpByAddress(address): ProfilePictureInfo - Method used to get the user's profile picture data. This method is also an aggregation of getCID, getPfpData, getPfpImage. return value will be src = image src, alt: nft name.
• registerSubprotocol(ordered, primary, active, nftAddress, name, fee): ethers.ContractTransaction - Method used to register new sub protocol to cip.
