How on-chain royalties really work
By the end of this lesson you can
- →Explain why a token contract cannot observe that a transfer was a sale
- →Distinguish a royalty standard that signals from a mechanism that enforces
- →Compute the revenue effect of voluntary compliance on a creator's secondary income
- →State which payments are genuinely enforceable on-chain, and what each costs

This lesson opens with The Operator Filter, November 2022 to February 2024.
- What happened
- Creator royalties were never collected by the token standard. They were paid because marketplaces chose to deduct and forward them. In November 2022 OpenSea introduced the Operator Filter, a code snippet a collection could adopt so that its tokens would refuse transfers through venues which did not enforce creator fees. Rival venues including Blur, Dew and LooksRare integrated the shared Seaport protocol and routed around the blocklist. OpenSea's chief executive stated the tool had not achieved what was hoped and lacked support across the ecosystem. On 31 August 2023 OpenSea sunset the filter and moved to optional creator fees for new collections, with enforcement continuing for existing collections and non-Ethereum chains until 29 February 2024. Yuga Labs responded that it would work toward preventing OpenSea from trading its collections.
- The decision point
- The enforcement attempt lasted about fifteen months and failed for a reason that was structural rather than commercial. A token contract sees a transfer. It does not see a payment, because the payment is a separate movement of a separate asset, frequently on a separate transaction path. Everything built to enforce royalties therefore had to work by restricting who could receive a transfer, which is a blocklist, and a blocklist maintained by one competitor against others has an obvious equilibrium.
What you will be able to answer
- →Why can a contract not enforce a royalty?
- →What does a royalty standard actually do?
- →Why did the blocklist approach fail?
- →What is genuinely enforceable on-chain?
Orientation and Year One are open: anyone can read them without an account. From Year Two onward the lessons are for enrolled learners, because progress through the later years only means anything if it is tracked against a record.
It is free. We do not sell the list and there is nothing to buy at the end of it.

Contested
Whether marketplaces were obliged to enforce royalties, or were right to make them optional under competitive pressure, is a live argument in which serious people disagree. This lesson takes no position on that. It establishes what the mechanism can and cannot do, which is not contested by either side.
Some chains and some token standards implement transfer-level fees natively, which changes the enforceability picture on those chains specifically. The argument here concerns the dominant standards where a transfer and a payment are separate.
