What is a 'wrapped coin' (e.g., WETH) and why do some NFT art platforms use it?
Answer: An ERC-20 version of a native coin that enables smart contract interactions like bidding
Wrapped ETH (WETH) is an ERC-20 representation of ETH that allows it to interact with smart contracts for features like off-chain bids.
Which term describes the total market value of all NFTs in a collection, calculated using the floor price in coins?
Answer: Floor market cap
Floor market cap = floor price × total supply of NFTs in the collection, giving a quick snapshot of the collection's overall value.
An NFT art collector 'sweeps the floor.' What does this mean in coin-spending terms?
Answer: Purchasing multiple lowest-priced NFTs in a collection at once
Floor sweeping means buying several of the cheapest-listed NFTs in a collection rapidly, often to accumulate holdings or signal demand.
What risk does extreme coin price volatility pose to an NFT art collector's portfolio?
Answer: The fiat value of their NFT holdings can drop sharply even if coin-denominated prices stay the same
Since NFTs are priced in coins, a drop in the coin's fiat price directly reduces the dollar value of the NFT portfolio even without any change in the NFT's coin-denominated price.
What is a 'Dutch auction' mint in the context of NFT art priced in coins?
Answer: An auction where the starting price decreases over time until someone buys
In a Dutch auction, the NFT's coin price starts high and decrements over time, incentivizing buyers to decide their own acceptable price point.
What does 'coin allocation' mean in a whitelisted NFT art mint?
Answer: The number of NFTs a whitelisted wallet is permitted to mint
Coin allocation (often called mint allocation) specifies how many NFTs a whitelisted address is allowed to purchase during a presale.
A digital coin artwork NFT is listed for 0.5 ETH but sells via a MATIC offer on a cross-chain platform. What process enables this?
Answer: A cross-chain bridge or marketplace escrow converts or settles the trade across chains
Cross-chain platforms use bridging protocols or internal settlement layers to facilitate trades between coins on different blockchains.
