What Seaport does

• Settles OpenSea listings, offers and sales on Robinhood Chain
• Orders are signed off-chain and only hit the chain when they fill
• Seaport 1.6 at its canonical cross-chain address

Seaport is the order-settlement protocol behind OpenSea and a number of other marketplaces: offers and considerations are signed off chain and matched on chain, so a listing costs nothing until it fills. Version 1.6 is deployed on Robinhood Chain at the same canonical address it uses elsewhere. Separately, DefiLlama credits OpenSea’s DEX aggregator with $1.56M over 24 hours and $102.9M all time on this chain on 18 September 2026.
