Royalty Enforcement Mechanisms vs Optional Royalties

Guaranteed revenue: Protocols like Manifold (ERC-2981) and 0xSplits ensure royalties are hard-coded into the smart contract, making them non-negotiable. This matters for professional artists and studios who rely on secondary sales for sustainable income. Projects like Art Blocks and Yuga Labs have used these to secure millions in creator fees.

Preserves collection value: By disincentivizing wash trading and fee evasion on marketplaces like Blur, enforcement maintains a higher floor price and perceived value. This matters for high-value PFP and generative art collections where rarity and provenance are key. Data shows a 15-30% higher floor price sustainability on enforced collections.

Reduces market competition: Mandatory fees can fragment liquidity, as traders migrate to platforms with optional royalties for better margins. This matters for high-frequency traders and arbitrage bots operating on thin spreads. Marketplaces like Sudoswap (AMM model) gained initial traction by bypassing royalties entirely.

Requires ecosystem buy-in: Effective enforcement needs support from major marketplaces, indexers, and wallets. Standalone solutions can be circumvented. This matters for new protocols and chains trying to attract volume, as they must convince the entire stack (e.g., OpenSea, Gem) to comply.

Maximizes liquidity and volume: By making fees optional (e.g., Blur's model), marketplaces attract high-volume traders seeking the best price. This matters for NFTfi and lending protocols like NFTX and BendDAO, which require deep, liquid pools for collateralization.

Enables novel economic models: Optional royalties allow for experimentation with token-gated rewards, staking yields, or dynamic fees. This matters for gaming and social dApps where asset utility extends beyond pure speculation, as seen in projects like Parallel TCG.

On-chain enforcement (e.g., via transfer hooks on Solana, ERC-2981 with blocklist enforcement on Ethereum) ensures royalties are non-optional. This provides predictable, sustainable income for artists and protocols like Art Blocks and Tensorians. It matters for high-value collections where creator funding is critical to long-term roadmap execution.

Marketplace fragmentation occurs as creators block non-compliant platforms (e.g., Magic Eden vs. Tensor wars). This forces users to switch markets, harming liquidity. Technical overhead is high, requiring custom contract logic (like Metaplex's Token Metadata) that can break with standard wallets and aggregators, increasing integration complexity.

Optional royalties (adopted by Blur, Sudoswap) reduce transaction costs and friction, leading to higher trading volumes and liquidity. They maintain full composability with all wallets, marketplaces, and DeFi protocols (like NFTfi), as they rely on standard ERC-721 transfers. This matters for high-frequency trading and financialized NFT use cases.

Revenue becomes variable and often declines, as seen with OpenSea's shift to optional fees for non-blocklisted collections. This shifts the burden to creator-led incentives (like trait-based rewards), which require continuous active management. It matters for independent artists and smaller projects without the resources to run complex reward programs.

Guaranteed creator revenue: Protocols like Ethereum (ERC-721C) and Solana (Metaplex Core) enforce royalties on-chain, ensuring creators receive a consistent percentage (e.g., 5-10%) on all secondary sales. This matters for high-value art projects (e.g., Art Blocks) and brands requiring predictable, sustainable income.

Lower transaction costs for users: Marketplaces like Blur and Magic Eden (Solana) with optional royalties reduce effective sale costs by 5-10%, directly boosting trader profits. This matters for high-frequency trading and speculative markets where thin margins are critical.
