What’s a BUIDL NFT and a Loot Box?

DoraHacks’ open-source developer funding platform HackerLink has launched the function of releasing open-source projects’ NFTs. Each project submitted by the developers on Hackerlink can issue an open-source project’s NFT on the Ethereum network with just one click and is able to receive funding continuously via the following transactions of its BUIDL NFT.

Any BUIDL NFT can be traded continuously on Hackerlink. 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.

Traders, as supporters of the BUIDL and BUIDL NFT, can also yield from trading the spread. BUIDL NFT minters can customize benefits for the traders with codes using “Loot Box”. A loot box is a smart contract that contains any programmable behavior after a successful BUIDL NFT transaction.

A Loot Box can be designed from the perspective of transaction time, transaction price, holding time, etc., you name it. The programmable benefits are a hacker’s way to reward their supporters.

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.
