NFT Royalties Guide

Royalties allow NFT creators to earn a percentage of secondary sales. This is a key feature of the creator economy.

How do NFT Royalties work?

When you mint an NFT, you can specify a royalty percentage (e.g., 5%) in the smart contract. Every time that NFT is sold on a marketplace like OpenSea or Blur, 5% of the sale price is automatically sent to your wallet.

Marketplace Enforcement

Royalties are not automatically enforced by the token standard (ERC-721) itself on every transfer. They rely on marketplaces to respect the EIP-2981 royalty standard. Some marketplaces may make royalties optional to attract traders with lower fees.

Frequently Asked Questions

The royalty is deducted from the final sale price, so effectively the seller pays it (receiving less than the gross sale amount). The buyer pays the listed price.

It depends on the smart contract implementation. Most modern contracts (like Manifold or ThirdWeb) allow the contract owner to update royalty settings. Immutable contracts do not.

No. If you transfer an NFT directly wallet-to-wallet (OTC deal), no marketplace is involved to collect the fee. The transaction looks like a simple transfer on-chain, so no royalty logic is triggered.

EIP-2981 is the 'NFT Royalty Standard'. It provides a standardized way for marketplaces to query how much royalty should be paid and to whom. Before this, every marketplace had its own custom registry.
