Dgaming Hackathon Marketplace hub

A cosmos zone with built-in simplistic NFT marketplace and IBC connectivity. The main functions available are setting NFT (i.e. transferred from the zone) on sale with a set price in avstract currency and buying NFT on sale.

Hub RPC endpoint (used by the webapp):

1. TransferNFTokenToZone(ConnectionID, TokenID) TransferID //Initiates a transfer of NF token through the open connection
2. GetTransferStatus(TransferID) Status //Get initiated transfer status (in flight, success, fail)
3. PutNFTokenOnTheMarket(TokenID, Price) Status
4. BuyNFToken(TokenID) Status
5. GetNFTokenData(TokenID) TokenData
6. GetNFTokensOnSaleList() []TokenData // Get list of all tokens on sale
7. MakeDeposit(Amount) Status // Currency faucet

General scenario

User X makes a token in Zone A. User makes a "transfer and set price" IBC transactions to benefit from atomic fire-n-forget UI for selling NFTs.

User Y buys a token on the Marketplace, user X gets some currency on the marketplace.

What is done

Most basic types and service functions are implemented/stubbed according to the specification, along with some commands.

TODOs

• Rewrite ./x/hh/client/rest/rest.go, I haven't removed the nameservice code there yet.
• Add transaction commands to ./x/hh/client/cli/tx.go, there is only one command implemented.
• All the Keeper / Handler logic. Search for // TODO: comments throughout the project.
