When a marketplace enforces on-chain royalties via an operator filter registry, what does it restrict?
Answer: Transfers to marketplaces that do not honor creator royalties
Operator filter registries block approved operators (marketplaces) that bypass royalties, enforcing payment at the transfer level.
In a cross-chain NFT marketplace integration, what is a common method to represent an NFT on a destination chain?
Answer: Lock the original and mint a wrapped/bridged representation on the target chain
Bridges typically lock or escrow the original token and mint a corresponding wrapped version on the destination chain.
Why should a marketplace integration validate the order signature on-chain during fulfillment?
Answer: To ensure the order was genuinely authorized by the seller and not forged
On-chain signature verification confirms the seller signed the exact order terms, preventing forged or tampered listings from executing.
What problem does a 'nonce' per maker address solve in marketplace order management?
Answer: It allows bulk cancellation of all of a maker's open orders in one transaction
Incrementing a per-maker nonce invalidates all previously signed orders at once, enabling cheap mass cancellation.
When displaying NFT metadata from tokenURI, why should an integration handle IPFS gateways carefully?
Answer: IPFS content may be slow or unpinned, so fallback gateways or pinning improve reliability
IPFS-hosted metadata can become unavailable if unpinned, so robust integrations use multiple gateways or pin content themselves.
What is the purpose of a marketplace fee recipient parameter within an order's consideration items?
Answer: It directs a portion of the sale proceeds to the marketplace as a platform fee
Consideration items can include a fee recipient so the protocol automatically pays the marketplace its commission on settlement.
A bulk listing feature signs many orders at once. Which approach lets the user approve them with a single signature?
Answer: Constructing a Merkle tree of orders and signing the root
Bulk signing builds a Merkle tree of order hashes so one signature over the root authorizes all included orders.
