The blueprint for the Piers Rugyard NFT collection minting and auction component. Use it for inspiration, or just to check if I can't rug you.

Components

• Stokenet: component_tdx_2_1czvpp7w2htcj39n8qxkxew62ltaz6aaz97206vmahgdyg54fwnyekz
• Mainnet: component_rdx1cq86467tkaj0dsjavw2asjwugw5rggp3nf7hs3z30577xlj6nv22wr

How it works

• Piers Rugyard NFTs are minted by the owner
• Owner sets the component to active to allow auctions to start and starts the first auction
• The auction has a duration and a buffer (time before auction ends). If a bid is made in the buffer, the auction is extended.
• Accounts can bid on the NFT with XRD. Note that it's not possible to retract a bid.
• If the new bid is valid, the previous bid is immediately returned to the original account.
• Once the auction ends, bidding is no longer possible and the auction must be settled. Settling an auction is incentivized with 5% of the winning bid for the settler to keep things moving smoothly.
  • If an auction ends without bids, the first bidder after the auction ended will be the winner of the auction. The auction will be settled immediately.
• After an auction is settled and there is another NFT available to be auctioned, a new auction will start automatically.

An account locker is used to store/route reward and NFT deposits.
