Usage

Initialization

First set is to initialize the SDK with the following:

import MoonwalkerProfileSdk from "moonwalkerswap-profile-sdk";

const moonwalkerSdk = new MoonwalkerProfileSdk();

You can pass optional arguments to the constructor:

• provider - custom RPC Provider instance if you want to use custom configuration, if not provided defaults to provider with random node from the list of RPC nodes
• chainId - what chain ID to use, if not provided defaults to 56

import MoonwalkerProfileSdk from "moonwalkerswap-profile-sdk";
import { ethers } from "ethers";

const customProvider = new ethers.providers.JsonRpcProvider("https://example.com");

const moonwalkerSdk = new MoonwalkerProfileSdk(customProvider, 97);

getUsername

Returns username for a given address. If the address does not have a profile or there is an error - returns empty string "".

import MoonwalkerProfileSdk from "moonwalkerswap-profile-sdk";

const moonwalkerSdk = new MoonwalkerProfileSdk();
const username = moonwalkerSdk.getUsername("0x123456789");
console.log(username); // "Johnathan"

getTeam

Returns team information for the team ID. In case of network error returns null. Note that at the moment points will return 0 for all teams (total team points will be calculated soon).

import MoonwalkerProfileSdk from "moonwalkerswap-profile-sdk";

const moonwalkerSdk = new MoonwalkerProfileSdk();
const team = moonwalkerSdk.getTeam(1);
console.log(team);

getProfile

Returns full profile data for a given address. Under the hood retrieves username and team data using getUsername and getTeam and combines it with data from the profile contract. If address does not have a profile - returns { hasRegistered: false, profile: null }. At the moment does not retrieve achievements (see getAchievements).

It also sets profile_${address} cookie containing username and avatar (only for swap.moonwalker.network domain)

import MoonwalkerProfileSdk from "moonwalkerswap-profile-sdk";

const moonwalkerSdk = new MoonwalkerProfileSdk();
const profile = moonwalkerSdk.getProfile("0x123456789");
console.log(profile);

getAchievements

Returns array of achievements for a given address. If address has no achievements or no profile at all - returns empty array [].

import MoonwalkerProfileSdk from "moonwalkerswap-profile-sdk";

const moonwalkerSdk = new MoonwalkerProfileSdk();

const achievements = moonwalkerSdk.getAchievements("0x123456789");
console.log(achievements);

Roadmap

Current version of this SDK is 90% copy of existing from moonwalkerswap-frontend repo. There are several improvements to be made in the future versions of this SDK:

• [ ] Better error handling (common bad status codes or broken internet connection)
• [ ] Allow username & avatar cookie to be configurable or optional
• [ ] Validate addresses and don't attempt to fetch data if address is not valid
• [ ] NodeJS support. Currently it works out of the box only in browser. Need to research different options for cross-fetch and choose the one that provides less friction and increases bundle size the least.
