OpenSea review

Custody stays with you

Listing on OpenSea does not hand over your NFT. The Seaport protocol keeps the asset in your wallet and each order carries its own scoped approval, which you can see and revoke. That design decision is why the marketplace with the most listings is also among the safest to list on, and it is worth checking before using any competitor.

A fee history that reads like a war record

2.5% originally, cut to 0.5%, a zero-fee promotion around the SEA token launch, and 1% since September 2025. Royalty policy shifted more than once between 2022 and 2024 as well. Every number is published, and the volatility tells you how hard Blur's arrival hit — the incumbent had to rebuild its economics in public.

Where the volume went, and came back

Professional traders left for Blur in 2023 and market share recovered sharply after the SEA token announcement in early 2025. Sales are verifiable on-chain, which is more than can be said for the raw volume figures this sector quotes.

Who it suits

Casual buyers and creators, who get the largest catalogue, the safest listing flow and tooling that does not assume you trade for a living.

One habit worth keeping

Review your outstanding approvals periodically and revoke the ones you no longer need. Most NFTs stolen from wallets left through an approval signed months earlier on a site the owner had forgotten.
