DoraHacks’s BUIDL NFT Trading Guide

DoraHacks’s BUIDL NFT Trading Guide

Any BUIDL NFT can be traded continuously on DoraHacks. Whoever offers a higher price than its current price can purchase the BUIDL NFT at any time. For every transaction of the NFT, the minter (the project owner) will receive a corresponding return.

Some BUIDL NFTs have a “Loot Box” plugged in. A loot box is a smart contract that contains any programmable behavior after a successful BUIDL NFT transaction, which means if you buy a BUIDL NFT with a Loot Box containing an airdrop or whitelisting chance, you can automatically get it with your wallet address!

The minter will receive a 20% of the premium (the price difference) and ⅓ of the sales tax paid by the buyer (equivalent to 2% of the total selling price) from every transaction of the BUIDL NFT.


If the initial price of a BUIDL NFT is 10 $DORA and the purchasing price of its first transaction is 20 $DORA, then the premium is 10 $DORA.

∴ The minter will receive 10 $DORA x 20% + 20 $DORA x 2% = 2.4 $DORA from the first transaction.

Let’s assume the purchasing price of its second transaction is 40 $DORA, then the premium is 20 $DORA.

∴ The minter will receive 20 $DORA x 20% + 20 $DORA x 2% = 4.8 $DORA from the second transaction.

And recursively.

So in this example, the total income of the minter is 2.4 $DORA + 4.8 $DORA = 7.2 $DORA from the first two transactions.

  • Minter — project owner, the creator of the NFT.
  • Buyers — NFT’s previous or new owners.

How to Buy/Sell a BUIDL NFT?

  • Buying a BUIDL NFT does not amount to owning the project.
  • There will be an additional 3% of sales tax, which 2% will go to the minter and 1% for the platform when you are purchasing your interested BUIDL’s NFT.
  • Minter will receive 20% of the premium + 2% of the total price every time when the BUIDL’s NFT is being traded.
  • The current Owner of the BUIDL’s NFT will receive 70% of the premium when the next buyer buys the NFT.
  • The platform will receive 10% of the premium + 1% of the total price.
