Tickets are NFTs and can be traded while a draw is running. The CONTRACT decides whether trading is open, not the draw's database status, so trust tradingOpen in this result rather than inferring it from the phase. A completed sale pays a fee read from feeBasisPoints() on the market contract, and part of that fee goes into the draw's prize pool -- the share is prizeShareBasisPoints() on the same contract. BOTH are admin setters (fee ceiling 10%), so read both rather than assuming a rate or a split: a seller's proceeds are the price minus that fee.

Read from the chain, so it works for a wallet that entered without ever signing in to the website. SCOPE: this reads THIS DEPLOYMENT's prize escrows, and the result names in escrowsChecked exactly which escrows it consulted. Contract week ids reset when the contracts are redeployed, so a prize sitting in an escrow from an EARLIER deployment is out of reach here and no weekId will find it. With no weekId this scans the most recent 26 contract weeks on those escrows and tells you the exact range it covered. The claim window is 180 days from the award, so a prize older than that SCAN window may still be claimable -- pass an explicit weekId (the CONTRACT week id, which luckdrop_get_results reports) to reach an older week ON THOSE ESCROWS directly. This returns an UNSIGNED transaction ({to, data, value}). This service never signs for the user and never holds keys. The user must approve and send it from their own wallet on Base Sepolia, and once mined it CANNOT be undone. NETWORK: LuckDrop is currently running on Base Sepolia, a TEST NETWORK.
