15. 🏆 Bounties and Prizes

16. 1. Create an example NFT marketplace
The purpose of this bounty is to
demonstrate the creation of a marketplace
using the SDK. Create a project that will
showcase the SDK to be used to create a
functional NFT Marketplace that supports
the listing of NFT-standard tokens (1155/721)
and the purchase of tokens using
HRC20/ONE tokens.
Prize: $3000 USD in ONE tokens

17. 2. Create an NFT game with token utility (e.g. token gating) using the
sdk and onchain VRF
The purpose of this bounty is to
demonstrate the use of the SDK
to create a game with utility for
gating access. The game will
utilise NFT standards
(hrc1155/721) and tokens (hrc20)
and demonstrate the use of
tokens to restrict user access.
Prize: $2000 USD in ONE tokens

18. 3. Integrate NFTs with the SMS wallet using the SDK
The purpose of this bounty is to
integrate the SDK with the SMS
Wallet to allow users to view a
list of the NFTs that they own on
various platforms and smart
contracts associated with the
SMS Wallet address. Users can
add NFT contracts to the SMS
Wallet Gallery page
Prize: $1000 USD in ONE tokens

19. 4. Create a visualisation / analytics tool for HRC20/721/1155
transactions
The purpose of this bounty is to
create a visualisation and analytics
tool that can accept multiple wallet
addresses and retrieve all
transactions that a user has
performed on these address. Using
the SDK and existing APIs the tool
will collect all the transactions that
have occurred on-chain for the user
and display this on a dashboard.
Users can set time range and filters
to view the transactions that they
have performed on-chain.
Prize: $3000 USD in ONE tokens

20. 5. Create a tutorial using the NFT SDK and harmony VRF to issue
random NFTs to users
Create a tutorial with video and
accompanying gitbook that showcases
Harmony VRF on-chain and integrating
the smart contracts with the Harmony
Marketplace SDK. The goal is to
demonstrate to beginner/intermediate
users how to use the SDK, Harmony
VRF, and create a simple smart
contract that can be used by others to
create on-chain randomness for
creating random NFTs (random traits,
properties, etc). The sample Dapp
should allow a user to connect their
wallet, purchase tokens with HRC20 or
ONE tokens, and receive an NFT.
Prize: $1000 USD in ONE tokens

21. 6. Create a dapp that allows multiple users to stake together on the harmony
protocol (like pooltogether) where users can use the staking rewards to purchase
an NFT
Much like pooltogether; this Dapp allows users
to deposit ONE tokens into the smart contract
to earn staking rewards. The rewards are
accumulated and then used to purchase NFTs
on any NFT platform (e.g. NFT Keys, MADNft).
Depositors get governance tokens that can be
used to vote for the NFTs to purchase; and
depositors are randomly selected to get the NFT.
Use the SDK to interact with the smart contract
and accept ONE/HRC20 tokens for deposit. The
contract should swap all deposited tokens for
ONE and give users equivalent governance
tokens. Tokens can be redeemed for ONE tokens
if user decides to deposit.
Prize: $2000 USD in ONE tokens

22. 7. Bug bounty for Harmony Marketplace SDK (enhancements PR)
Create enhancements and useful
additions to the Harmony Marketplace
SDK and do a PR to the repository.
Limited to 3 submissions
Harmony will reward based on the
enhancements made and may bundle
a few enhancements together for
payment.
Prize: 10 bounties at $50 USD in
ONE per bounty

23. 8. Bug bounty for Harmony Marketplace SDK (Coding errors / Bugs)
Identify software / api / coding errors in
the Harmony Marketplace SDK and do
a PR to fix the errors. Limited to 5
submissions
Harmony will reward based on the
errors found and may bundle a few
errors together for payment.
Prize: 10 bounties at $50 USD in
ONE per bounty

24. 9. Bug bounty for Harmony Marketplace SDK (Documentation Error)
Identify documentation errors in the
Harmony Marketplace SDK and do a
PR to fix the errors. Limited to 10 errors
found in the SDK
Harmony will reward based on the
document errors found and may
bundle a few errors together for
payment.
Prize: 3 bounties at $300 USD in
ONE per bounty
