Attention ETHGlobal Hackathon Participants. We have a $1000 Bounty available for best integration of Merits. The basic requirement is to incorporate Merits (Blockscout Points) into your application in some way. Users can earn Merits through different activities in your app and you can distribute them via the API. Below you will find more info on the program and the API for checking user Merits, distribution, and login processes.

​
What are Blockscout Merits?

Merits are digital rewards collected by interacting with Blockscout and Blockscout-related apps and by participating in various activities (like contests, X participation, telegram participation, app participation and more). Merits are chain agnostic and can be incorporated into any application. For more details see the Merits section of the docs.

​
Using Merits as an activity incentive

Merits are used to incentivize different activities within the Blockscout universe. For example:
  • Blockscout explorer basics: Earn Merits by signing up for the program. Once you are signed up, you can earn additional Merits by completing a daily claim. You can also share your referral code and earn Merits when new users sign up with that code.
  • Telegram mini app. The telegram Blockscout Merits Bot allows for direct communication with subscribers. Users who download the bot receive extra Merits -> https://t.me/blockscout_merits_bot
  • Swapscout swapping app. Merits are incorporated in the app so that users can view their balance and earn Merits for their swaps. https://swap.blockscout.com/. This is a good example of an external app that incorporates Merits.
  • Revokescout app. Merits are used to incentivize users but there is no sign in or interface. We simply check addresses that use the application and distribute Merits to those addresses.
  • Blockscout campaigns. Participants in time-gated campaigns such as rating Dapps or Twitter(X) contests receive additional Merits. We collect the Ethereum addresses of winners and distribute Merits manually.
  • Partner campaigns. Merits are allocated to users of other protocols as an additional incentive for use. Partners provide us with a list of addresses and tasks they completed and we distribute accordingly.

​
Integrating Test Merits into your application

Merits can be integrated in different ways into your application. Ideas may be to include Merits as a reward for user interactions with your app or a general reward for any activity. Merits can be distributed to users via the API. Users can have the ability to sign up for Merits through your app and/or login to their Merits account. You can also display individual Merits balances and leaderboard balances within your application. However, these are optional integrations. To qualify for the bounty, you simply need to provide Merit incentives for certain activities, and then distribute those merits appropriately. As long as you have the participant’s Ethereum address you can distribute Merits.
Note: You can retrieve basic data without an API key, but for interactivity purposes you will need to request one via our Discord channel. See below.
