NFT creator royalties are a percentage of each secondary-market resale that flows back to the original creator’s wallet, typically set between 2.5% and 10% when a collection is minted. They are written into the NFT’s smart contract, calculated automatically at sale, and paid in the same transaction that transfers the token. The part most creators learn too late: those payments are not guaranteed. The dominant technical standard treats royalties as a voluntary signal, and most major marketplaces now let buyers or sellers decide whether to honor them.
How the Payment Actually Happens
A smart contract is a self-executing program on the blockchain that handles the mechanics of an NFT sale. When a buyer completes a purchase through a marketplace, the contract confirms the sale conditions, calculates the royalty as a percentage of the price, and splits the incoming funds in a single transaction. The seller receives the bulk of the payment, the marketplace takes its platform fee, and the royalty portion routes to the creator’s wallet.
The automation is real, but it can be misleading. The contract attached to an NFT doesn’t force a buyer to pay royalties the way a vending machine forces payment before dispensing a snack. It records the royalty terms; whether those terms are honored depends on what the marketplace decides to do with that information.
Why Royalties Aren’t Automatically Enforced
The most widely used royalty standard is ERC-2981, an Ethereum specification that exposes a royaltyInfo() function any marketplace can query to retrieve the recipient address and the amount owed on a given sale price.1Ethereum Improvement Proposals. ERC-2981: NFT Royalty Standard The creator sets the percentage at minting and it lives permanently in the contract’s metadata.
ERC-2981 is a signaling standard, not an enforcement mechanism. The specification itself states that “the royalty payment must be voluntary, as transfer mechanisms such as transferFrom() include NFT transfers between wallets, and executing them does not always imply a sale occurred.” It adds that if a marketplace chooses not to implement the standard, “no funds will be paid for secondary sales.”1Ethereum Improvement Proposals. ERC-2981: NFT Royalty Standard
The underlying architecture works against mandatory royalties too. An NFT can move between wallets without touching any marketplace. There is no reliable on-chain way to distinguish a genuine sale from a gift, a transfer between someone’s own wallets, or a sale where the actual payment happened off-chain. Someone can list an NFT for zero on a royalty-honoring platform while receiving the real price separately, producing a royalty of zero. Wrapper contracts can also move an NFT into a new token that carries no royalty terms.
These are the practical reasons marketplace policy, not the smart contract, ends up deciding whether creators get paid.
Where the Major Marketplaces Stand
Marketplace policies shifted dramatically starting in 2022, and the current picture is a patchwork.
OpenSea treats creator earnings as either enforced or optional depending on the collection. Where royalties are enforced through on-chain mechanisms, OpenSea honors them. Otherwise, sellers choose whether to include creator earnings in the sale price.2OpenSea. What Fees Do I Pay on OpenSea OpenSea had launched an Operator Filter tool in late 2022 that blocked sales on platforms not paying royalties, then disabled it in August 2023, citing a lack of industry-wide adoption.
Magic Eden makes royalties optional on its Solana marketplace, where buyers can pay full royalties, half, or none. Full is the default, but the buyer decides. Collections built on the Metaplex MIP-1 standard can enforce mandatory royalties and bypass this optional flow. On Ethereum, Polygon, Base, and Bitcoin Ordinals, Magic Eden respects whatever royalties the collection has set.3Magic Eden. How Optional Royalties Work on Magic Eden’s Solana Marketplace
Blur, which grew rapidly by undercutting OpenSea on fees, set a minimum royalty of just 0.5% for collections without on-chain enforcement. The broader pattern across the industry is consistent: platforms that drop or minimize royalties attract trading volume, which pressures the platforms that still enforce them to loosen up.
Tools That Create Real Enforcement
Because ERC-2981 only signals, creators who want actual enforcement need additional tooling.
Operator filter registries were the first generation. A creator maintains a list of blocked or approved smart contract addresses. When a transfer is attempted, the NFT contract checks the registry and reverts the transaction if a blocked operator is involved, such as a marketplace known not to pay royalties.4npm. operator-filter-registry The weaknesses show up quickly. Blocklists have to be updated manually as new royalty-avoiding marketplaces launch. Anyone can deploy a fresh contract that isn’t on the list. And the approach only holds if enough major platforms remain on the approved list to keep the collection liquid. OpenSea’s decision to shut down its own operator filter suggested even a major platform found the maintenance burden unsustainable.
ERC-721C, developed by Limit Break, takes a more aggressive approach. It introduces transfer security policies with multiple strictness levels. At the lower levels, the protections resemble operator filters and can still be worked around with wrapper tokens. At the higher levels, the creator can restrict which contracts are even allowed to hold the NFT, which blocks most bypass techniques. That comes with a real cost: the more locked-down the NFT, the harder it is to use in DeFi protocols, lending platforms, or any new application the creator didn’t anticipate. Security levels can be adjusted over time, so creators can escalate restrictions if they see abuse.
Legal Standing: No Copyright Right to Resale Royalties
There is no federal statute in the United States that entitles NFT creators to a resale royalty. The first sale doctrine, codified in 17 U.S.C. ยง 109(a), says that once a lawfully made copy is sold, the copyright holder’s right to control distribution of that particular copy is exhausted.5Office of the Law Revision Counsel. United States Code Title 17 – Section 109 In the physical world, a painter can’t demand a cut when a canvas is resold at auction. Courts haven’t extended first sale to purely digital transfers, largely because moving a digital file involves making a copy, which implicates the separate reproduction right that section 109 doesn’t cover. But the absence of a digital first sale doctrine doesn’t create an affirmative resale right for creators either.
What exists in its place is smart contract code plus the terms of service of whatever platform facilitates the sale. If a buyer transfers an NFT through a peer-to-peer transaction that bypasses all marketplace infrastructure, the creator has no clear legal claim to a royalty. Treat royalties as a technology-dependent revenue stream, not a legal entitlement.
Taxes on the Royalties You Do Collect
The IRS treats digital assets, including NFTs, as property, and royalty income from NFT resales is taxable. For creators who mint and sell regularly, royalty payments are generally treated as ordinary income reportable on Schedule C. They’re subject to self-employment tax of 15.3% (covering Social Security and Medicare) on top of the regular income tax rate. Self-employment tax applies to net earnings of $400 or more per year.6Office of the Law Revision Counsel. United States Code Title 26 – Section 1402
IRS Notice 2023-27 introduced a look-through analysis for whether an NFT qualifies as a collectible, examining what the token actually represents. An NFT linked to digital art may be treated as a collectible; one representing a concert ticket or game item might not. Long-term capital gains on collectibles face a maximum rate of 28%, higher than the rates that apply to most other capital assets.7Internal Revenue Service. Notice 2023-27 – Treatment of Certain Nonfungible Tokens as Collectibles This mostly affects buyers reselling at a profit, but it can influence what those buyers are willing to pay.
Marketplace reporting is a separate layer. For 2026, third-party settlement organizations are required to issue a Form 1099-K when a seller’s total payments exceed $20,000 across more than 200 transactions in a calendar year.8Internal Revenue Service. Understanding Your Form 1099-K Falling below that threshold doesn’t exempt the income from being reported; it only means no form gets generated. Creators paid in cryptocurrency also need to record the fair market value of each royalty payment in U.S. dollars at the time it hits their wallet, because that value determines the taxable amount.
Practical Steps to Protect Royalty Revenue
Given the enforcement gaps, creators who want to maximize what they actually collect should make deliberate choices at every stage.
- Choose an enforceable standard. ERC-2981 alone is not enough if on-chain enforcement matters. Consider building on ERC-721C or a comparable standard with transfer security policies, understanding that higher security levels limit where and how the NFT can be used.
- Set a reasonable percentage. Royalties in the 5% to 7.5% range tend to be honored more consistently than 10%. Higher rates give buyers stronger incentives to route around them.
- Monitor marketplace policies. A platform that enforces royalties today may make them optional next quarter. Tracking policies on OpenSea, Blur, Magic Eden, and any other venue where a collection trades is ongoing work.
- Use a splitter contract for collaborations. ERC-2981 returns only one recipient address, so multi-creator projects should deploy a payment splitter contract and set that as the royalty recipient. Test the split logic before minting.
- Track payments for taxes. Every royalty payment is a taxable event. Record the date, the cryptocurrency amount, and the fair market value in U.S. dollars at the time of receipt.
Creators who minted in 2021 expecting a reliable passive income stream have learned hard lessons about the gap between what smart contracts promise and what marketplaces actually deliver. The tooling for on-chain enforcement exists and is improving, but every option carries trade-offs in liquidity and usability that need to be weighed before minting, not after.
