OpenSea Treasure Chests is part of the platform’s gamified Rewards program, where users level up chests through on-platform activity like trading NFTs, completing swaps, making accepted offers, and finishing Voyages/quests.
At the end of each wave (rewards period), chests unlock to reveal Treasures (progress-based rewards) plus possible crypto tokens or NFTs from a community Rewards Pool. Higher-level chests with better progress offer improved chances at bigger prizes.
Wave 6 Treasure Chests became unlockable on or after April 2, 2026. All participating users from the prior wave get a Treasure; those with significant progress may also receive additional crypto and NFT prizes. There are 14 tiers of Treasure in Wave 6, based on your progress.
You must open your Wave 6 chest within 20 days by April 22, 2026 at 1:30pm ET. Previous waves’ chests can no longer be opened. Go to your Rewards profile on OpenSea usually at opensea.io/rewards or accessible via the Rewards tab after connecting your wallet. You’ll need enough of the chain’s native gas token in your wallet to cover claim transaction fees. Activity from linked wallets (across supported chains) contributes to progress.
12 main levels, each with 3 tiers/stars for finer progress. Complete Voyages; on-chain quests of varying rarity: Common to Legendary, trade NFTs, use swaps, etc. Actions earn XP that fills your chest. Every chest at wave end contains a Treasure; higher chests = better loot odds and bigger shares from the Rewards Pool.

The program ran in multiple waves, often tied to building engagement ahead of OpenSea’s SEA token considerations though timelines shifted. Past waves followed similar unlock patterns shortly after each period ended. For the most accurate steps or to check your specific chest, log into OpenSea with the wallet you used for activity and visit the Rewards section directly.
Wave 6 which ran roughly February 18 to March 30, 2026 was explicitly the last rewards wave. No additional waves are planned. This means Wave 6 represents your final chance to accumulate progress-based Treasures through on-platform activity. Treasures you’ve already earned from prior waves especially 3–6 remain in your account unless you take certain actions.
Every participant who had activity in Wave 6 receives at least one Treasure; there are 14 tiers based on your progress level. Higher-tier Treasures from better chest levels improve your odds and size of additional crypto or NFT prizes drawn from the Rewards Pool. Treasures themselves are not direct $SEA tokens, but they are meaningfully considered by the OpenSea Foundation when determining any future $SEA token distribution.
This is the biggest current decision point for most users: Starting April 2, 2026, OpenSea offers an optional refund of platform fees you paid during Waves 3–6; only the portion OpenSea retained, not fees spent on rewards or certain beta activities. If you claim the refund: You forfeit all Treasures earned in Waves 3–6.
Those Treasures are removed from your account and will no longer receive consideration for $SEA at TGE. If you skip the refund: You keep your Treasures, which remain eligible for future $SEA consideration. You do not get the fee money back. The refund is an all-or-nothing choice for Waves 3–6 — you can’t pick and choose individual waves.
Waves 1 and 2 are not eligible for this refund. Many users with low or zero fees paid are skipping the refund to preserve their Treasures for potential $SEA value. The $SEA TGE has been delayed multiple times due to market conditions, with no new confirmed date. Treasures from the rewards program including Wave 6 serve as one signal for potential airdrop eligibility and sizing.
Historical on-chain activity on OpenSea may also be factored in separately by the Foundation. Opening your chest and keeping Treasures keeps you in the running for any eventual distribution. Taking the refund removes you from that consideration for the affected waves. There is no guarantee of a large or any $SEA airdrop — it depends on the Foundation’s final decisions.
0% platform fees on token trading is currently live for a 60-day window which is separate from the refund. Claiming rewards requires gas fees on the relevant chain(s). If your chest is low-tier, the immediate prizes may be modest, but the Treasure itself still carries potential long-term signaling value for $SEA.
Community sentiment is mixed: some users are frustrated with the refund structure, while others prioritize keeping Treasures for the unknown upside of $SEA. Check your specific Treasure tier, any immediate prizes, and the refund amount offered. If your refund is very small or zero, most participants are choosing to keep the Treasures.
