Leaderboards

Use our SDK and APIs to quickly build applications with **micro-transactions**, **missions**, **rewards**, and **community competition**.

Welcome

There's a better way to revenue than advertising. The ability to charge fractions of a cent and tokenise your services will set you free.

Generate API Key

A full code example that rewards a given user 10 XP for completing an activity in an application.

We've partnered with no-code and low-code stacks to make it as easy as possible for builders and developers to experiment with web3 technologies.

Explore our case studies to see how builders are using no-code tools combined with our onchain game mechanics to rapidly build prototypes and applications.

Case Studies

[BuildShip](https://buildship.com/) is a visual backend builder that lets you ship APIs, scheduled jobs, backend cloud functions instantly. You can use BuildShip with OPENFORMAT templates to create web3 apps fast. Get started with one of the templates below.

Overview

Creates a web3 account for your user. You can learn more about web3 accounts in [Accounts & Profiles](../../../functions/accounts-and-profiles) in the key concepts section.

Create web3 Account

Reward a user with experience points (XP) for completing an action.

Reward a user with a badge for completing an action or mission.

Returns the user's experience point (XP) balance, the badges they have collected and the actions they have completed within that specific dApp.

Get User Information

Returns a leaderboard based on the amount of experience points (XP) users have earned.

Get Leaderboard

Checks whether the user has completed all of the actions that make up a mission, and whether they have already been rewarded for completing the mission.

Check Missions

Reward your existing users with on-chain experience points (XP). This template handles the process of issuing XP directly to users based on their unique identifier, making it easy to integrate gamification into your existing application.

XP Rewards Integration

Create a leaderboard which includes the names and images of the users within your app, by linking to your database. This leaderboard is based off the amount of on-chain experience points (XP) the users have earned.

Leaderboard

Easily integrate location-based rewards into your app. This template verifies user presence at specific locations using a set of given coords and automatically issues on-chain badges to their web3 account. Perfect for gamification, enhancing user engagement, and promoting exploration.

Geolocation Reward

Verify on-chain whether a given web3 account holds a specific badge. It's ideal for both online and offline access control.

Badge Access Verifier

Calculate your users level and their progression towards the next level based on the on-chain experience points (XP) they have earned. The XP requirements for levelling can be customised to determine how quickly the user progresses.

Level Progression Tracker

Checks whether a user has completed all the actions that make up a mission, and if they have, it rewards them with the appropriate XP and badges.

Check and Reward Missions

Generate an API Key Challenge for an account. Once you've generate your challenge, you need to [verify](/api-reference/endpoint/api-key/post-keyverify) it.

Challenge

Verify your signed challenge. You can sign your challenge using Metamask and our [signing tool](https://openformat-tools.vercel.app/).

Challenge verification

Trigger XP in your application when a user completes a specific action, such as registering, completing a task, watching a video or posting a comment. This is endpoint returns an [unsigned transaction](/architecture/transaction-lifecycle), which can now be signed in your application using your private key held in your local environment variables. Once signed, you can broadcast it using the [Execute Transaction](/api-reference/endpoint/transactions/post-transactionsexecute) endpoint; or if you prefer to wait for confirmation using the [Execute Transaction and Wait](/api-reference/endpoint/transactions/post-transactionsexecuteandwait) endpoint.
