Checked 2026-10-29 · sources belowOpenSea is an NFT marketplace and multi-chain token trading app on Ethereum, Solana, Base and 20+ other chains.

NFT sales pay 1%, taken from the seller's proceeds; mints in a primary drop carry a 10% fee; perps orders add 0.01% on top of Hyperliquid's own fees.

How DEX fees work: instead of a platform fee, each swap pays the fee of the pool it routes through (listed above where published). The interface itself may add its own fee.
Platform fees only. On-chain network/priority fees, pool (LP) fees and price impact are extra and vary by trade.
Is OpenSea legit?
OpenSea's terms say it never has custody of your assets. You can connect your own wallet, or sign up with email and get an embedded wallet provided by Privy (a third party). Embedded-wallet keys can be exported for EVM and Solana under Settings, Embedded Wallet.
