01ENTRY
A completed pair takes one position.
A pair enters the current batch only after Wallet B pays and both NFTs are minted. One pair counts as one batch entry.
The batch closes automatically when its tenth valid pair is created.
04 / THE BATCH
10 PAIRS ENTER.
3 MINT FREE.
Every completed pair enters a batch of ten. When that batch closes, three pairs receive both side fees back.
02SELECTION
Three pair positions are selected.
After the ten positions are complete, the contract derives three winning pair positions for that batch. Both tokens from a winning pair share the same outcome because the refund belongs to the original mint event.
The selection does not create a different NFT tier and does not alter metadata rarity.
03REFUND
Both side fees return, gas does not.
For each selected pair, Wallet A receives its side fee back and Wallet B receives its side fee back. Each wallet claims its own credit directly from the contract.
Network gas cannot be refunded because it is paid to Robinhood Chain validators for processing the transactions.
04SAME ORIGIN
Cost changes. Provenance does not.
Winning and non-winning pairs follow the same wallet and payment checks and create the same two-token structure. The refund changes the final cost only.
Every token remains connected to its paired token and original pair ID onchain.
