Tokens are sold to the highest bidder: STEM TAS operates on a traditional English auction model, where the token is sold to the highest bidder at the end of the auction period. A reserve price, set by the seller, must be met: The seller can set a reserve price for the token, which is the minimum price at which they are willing to sell the token. Bids below the reserve price are not allowed: Bids that are below the reserve price will be rejected by the platform. Bids are disclosed: All bids are transparent and visible to all users of the platform. The names of the seller and bidders are disclosed for each token auction: The identity of both the seller and bidders are disclosed for each auction, adding transparency and accountability to the process. Anonymous bidding is not permitted: All bidders must disclose their identity to participate in the auction. Auctions close 15 minutes after the first bid is received: Once the first bid is received, the auction period begins, and all bids must be submitted within a specified timeframe. The auction period lasts for 15 minutes, and if no further bids are received, the highest bidder wins the token. On-chain auction history (optional): The STEM TAS platform also provides the option for users to view on-chain auction history, allowing them to track previous auctions and analyze market trends. Overall, STEM TAS offers a robust and transparent token auction platform for STEM educational resources, providing an efficient and secure way for buyers and sellers to exchange tokens for valuable resources
If you want to see the full completed contract go ahead and clone and build this repo using
git clone https://github.com/Binwakil/nft-archiverse.git
yarn build
Now that you've cloned and built the contract we can try a few things.
Once you've created your near wallet go ahead and login to your wallet with your cli and follow the on-screen prompts
near login
Once your logged in you have to deploy the contract. Make a subaccount with the name of your choosing
near create-account nft-example.your-account.testnet --masterAccount your-account.testnet --initialBalance 10
near create-account market-example.your-account.testnet --masterAccount your-account.testnet --initialBalance 10
After you've created your sub account deploy the contract to that sub account, set this variable to your sub account name
NFT_CONTRACT_ID=nft-example.your-account.testnet
MARKET_CONTRACT_ID=nft-example.your-account.testnet
MAIN_ACCOUNT=your-account.testnet
Verify your new variable has the correct value
echo $NFT_CONTRACT_ID
echo $MARKET_CONTRACT_ID
echo $MAIN_ACCOUNT
near deploy --accountId $NFT_CONTRACT_ID --wasmFile out/main.wasm
near deploy --accountId $MARKET_CONTRACT_ID --wasmFile out/market.wasm
near call $NFT_CONTRACT_ID new_default_meta '{"owner_id": "'$NFT_CONTRACT_ID'"}' --accountId $NFT_CONTRACT_ID
near view $NFT_CONTRACT_ID nft_metadata
near call $NFT_CONTRACT_ID nft_mint '{"token_id": "token-1", "metadata": {"title": "My Non Fungible Team Token", "description": "The Team Most Certainly Goes :)", "media": "https://bafybeiftczwrtyr3k7a2k4vutd3amkwsmaqyhrdzlhvpt33dyjivufqusq.ipfs.dweb.link/goteam-gif.gif"}, "receiver_id": "'$MAIN_ACCOUNT'"}' --accountId $MAIN_ACCOUNT --amount 0.1
After you've minted the token go to wallet.testnet.near.org to your-account.testnet and look in the collections tab and check out your new sample NFT!
After you've minted your NFT you can make a view call to get a response containing the token_id owner_id and the metadata
near view $NFT_CONTRACT_ID nft_token '{"token_id": "token-1"}'
To transfer an NFT go ahead and make another testnet wallet account.
Then run the following
MAIN_ACCOUNT_2=your-second-wallet-account.testnet
Verify the correct variable names with this
echo $NFT_CONTRACT_ID
echo $MAIN_ACCOUNT
echo $MAIN_ACCOUNT_2
To initiate the transfer..
near call $NFT_CONTRACT_ID nft_transfer '{"receiver_id": "$MAIN_ACCOUNT_2", "token_id": "token-1", "memo": "Go Team :)"}' --accountId $MAIN_ACCOUNT --depositYocto 1
In this call you are depositing 1 yoctoNEAR for security and so that the user will be redirected to the NEAR wallet.
