OpenSea 2.5% Fee vs Ethereum Gas Fees

OpenSea's platform fee is 2.5% of sale price — predictable and low. Ethereum gas fees are variable and can range from $5 to $100+ depending on network congestion. Polygon gas fees are negligible (~$0.01).

When are Ethereum gas fees lowest?

Ethereum gas fees are typically lowest on weekends (especially Sunday mornings UTC) and during US/European nighttime hours. Tools like Etherscan Gas Tracker show real-time and historical gas prices.

What are OpenSea creator royalties?

NFT creators can set royalties (typically 5–10%) that are paid on every secondary sale. These are separate from OpenSea's 2.5% platform fee — buyers pay the total of both.
