Listing adapters

An adapter prices one venue listing and returns the exact call the Core may execute. The Core approves adapters one by one.

Shared interface

price(uint256 id, bytes params) → (address target, uint256 value, bytes data, address offerer)view

Quote a listing for exactly one Credit and return its execution target, ETH value, calldata, and seller.

Core.buyListing(address adapter, uint256 id, bytes params)

The Core checks its allowlist, bid, budget, and resulting custody before executing the returned call.

CreditStrategyAdapter

Reads CreditStrategy.nftForSale(id); zero means NotForSale.

Ignores params and returns the strategy's sellTargetNFT(id) call.

The strategy is the offerer for the returned quote.

SeaportBasicAdapter

Decode params as BasicOrderParameters for a Seaport 1.6 basic order.

Accept only an open native-ETH sale of exactly the requested Credit; payout recipients must be the seller or allowlisted.

The Core owner can change allowed recipients. After adapters are locked, recipients can be removed but not added.

setAllowedRecipient(address recipient, bool allowed)Core owner

Maintain the Seaport payout allowlist.

RecipientSet(recipient, allowed)

Allowlist change to index.
