Rarible vs SuperRare vs Curve Finance Liquidity Pools: Comparing NFT Royalties and AMM Mechanics 2026

---

Why this comparison matters in 2026

Over the past two years, the royalty debate has shifted from being just a “policy” issue to a “protocol” one for certain stacks. Meanwhile, Automated Market Makers (AMMs) have been busy fine-tuning their capital efficiency and fee routing. Here’s what’s come of it:

• If you're looking to secure some steady revenue from secondary NFT trades, the choice of your venue and chain is key. It can really influence whether those royalties are going to be just a best-effort deal or actually enforced at the protocol level (like what you see with RARI Chain). Check out more here.
• On the flip side, if you're after consistent take rates and a bit of liquidity recycling, the mechanics of Automated Market Makers (AMM)--think fee splits, admin-fee routing, how oracles are designed, and liquidation behavior--often have a much bigger impact on your profit and loss than those big headline “platform fees.” You can dive deeper into this here.

Here's a hands-on comparison of some solid integration tactics for startups and larger enterprise innovation teams.

Snapshot: what each platform actually does with fees/royalties

• Rarible
  • Service fee: Rarible has a sliding fee structure, ranging from 0.5% for transactions over $4,000 to a whopping 7.5% for those under $100. If you’re using community marketplaces that Rarible’s editor helps build, there’s actually a 0% Rarible fee! And if your project wants to set “community fees,” that's totally optional. For aggregated listings, they follow a similar 0.5% to 7.5% scale. Plus, if you lock RARI, you can eliminate Rarible.com fees altogether. (help.rarible.com)
  • Royalties: Creators get to set their royalties either at the minting or collection level, and Rarible is EIP-2981-compatible on both ETH and Polygon. They enforce these royalties for native listings and also ensure a lot of aggregated venues route royalties using their registry and wrappers. (help.rarible.com)
  • Hard-enforcement option: Over on the RARI Chain, royalties are built right in at the sequencer/node level. If anyone tries to skip the set royalty, transfers will just revert. (rari.foundation)
• SuperRare
  • Fees: When you make a primary sale, it’s split 85% for the artist and 15% for the SuperRare DAO. In secondary sales, the seller keeps 90% while the artist earns a 10% royalty, plus there's a 3% buyer fee that goes to the DAO. If you need it, the DAO treasury address is 0x860a80d33e85e97888f1f0c75c6e5bbd60b48da9. (help.superrare.com)
  • Royalty defaults and registry: For sales initiated through the protocol, there’s a standard 10% royalty, while newly minted works will automatically default to 10% in the Royalty Registry, but you can tweak that based on your terms. (campaigns.superrare.com)
  • New incentive: They’ve introduced “Collector Royalties,” which award the first collector a 1% royalty on the first qualifying secondary sale. This is paid from the network fee, not the artist’s 10%. And just a heads up, external sources mention there’s a halving schedule for this after the first sale. (medium.com)
• Curve Finance (AMM + crvUSD)
  • Pools (V2 CryptoSwap): The pools use an adaptive “price scaling” method to concentrate liquidity around an EMA-style internal oracle. The DAO sets the admin fees, and fee routing happens through updated burners and distributors to veCRV in crvUSD. (docs.curve.finance)
  • crvUSD’s LLAMMA: Liquidation works through bands/ticks (ranging from 4 to 50), and liquidation or de-liquidation is driven by arbitrage between the AMM’s internal price and an oracle. There are explicit parameters that control fees, admin fees, and interest rates, which ultimately affect borrower profits and losses. (docs.curve.finance)
  • Fee distribution: 50% of the pool trading fees go to veCRV (that’s the admin fee share), and these are converted and distributed weekly in crvUSD through the new FeeDistributor. (resources.curve.finance)

Royalties on Rarible in 2026: what’s actually enforced and where

Rarible is now working with three key layers that are important for handling royalties:

1. Rarible.com and native listings

• Creators can set royalties up to 50% for each item or across the whole collection, and they've got EIP-2981 support on both ETH and Polygon. The cool part? Royalty enforcement is a sure thing for any trades that happen on Rarible. Check out more details here!

Aggregated Liquidity

• Rarible brings together orders from big platforms and community marketplaces while making sure to honor the royalty settings from where they originated or from Rarible’s own royalty registry. This includes a cool wrapper approach for SudoSwap-style automated market makers (AMMs). What this really means is that when you check out on Rarible, creator fees are paid out even if the original marketplaces treat royalties as optional. However, it’s still up to the integration teams to double-check that the original collection has the creator fee fields set up correctly on platforms like X2Y2 or LooksRare, plus EIP-2981/registry data for SudoSwap, and so on. You can find more info on this here.

3) RARI Chain (Ethereum L3 powered by Arbitrum tech)

RARI Chain takes things up a notch by integrating royalty checks right at the sequencer level. So, if someone tries to dodge the royalty payments set up, the transaction simply reverts. This shifts royalties from being a "policy" issue to a "protocol" one. For startups looking to secure a steady revenue share from their brand's intellectual property, this is currently the most straightforward path to enforce royalties on-chain. Check it out at (rari.foundation).

Fee Reality Check for 2026 Launches

• If your Average Selling Price (ASP) is below $400, Rarible’s fee structure can really hit hard compared to items priced over $4,000. Unless you either lock in some RARI or make your transactions through a community marketplace that you manage, expect to pay a higher fee. For enterprise programs like ticketing or loyalty collectibles, where many items are priced under $100, it’s smart to budget for a 7.5% fee on both sides unless you take some of the steps mentioned below. You can read more about it here.

Emerging best practices on Rarible

• When you’re launching a game or NFT-fi project and want to bridge SudoSwap liquidity, make sure to share your collection's royalty rate using EIP-2981. Don't forget to register it in Rarible’s royalty registry! It’s also a good idea to run a test purchase flow on a staging marketplace to confirm that the wrapper is correctly directing the creator fee. You can find more info here.
• If your brand or legal agreements hinge on royalties, consider minting and trading on the RARI Chain. For those looking to trade across multiple venues, just make sure to bridge your assets while keeping the ERC-2981 metadata intact. Also, be transparent about which venues uphold those enforcement guarantees. Check out the details here.

Royalties on SuperRare in 2026: protocol-level defaults with DAO-aligned economics

SuperRare is still the go-to place for curated 1/1 art, and it’s got the numbers to back it up:

• When it comes to sales, 85% of the action is directed to artists, while 15% goes to the DAO. For secondary sales, there’s a nice little bonus: 10% goes straight to the original artist, plus a 3% buyer fee that heads to the DAO treasury. These rules are set in stone for trades that use SuperRare protocol contracts. Check it out here: (help.superrare.com).
• According to the Terms, newly minted works automatically start with a 10% royalty in the Royalty Registry. If you need to make changes after minting, just make sure to double-check that your contract and version are compatible before you go live. More info can be found here: (campaigns.superrare.com).
• The “Collector Royalties” program is pretty cool! It gives the first collector a 1% royalty, funded from the network fee on their first qualifying secondary trade where they’re not involved as a counterparty. Plus, third-party coverage follows a halving pattern afterwards. This helps to boost primary demand while keeping the artist's 10% intact. Dive into the details here: (medium.com).
• And let’s talk about treasury transparency! The DAO’s fee destination is open for everyone to see (0x860a80d33e85e97888f1f0c75c6e5bbd60b48da9), which is something that many finance teams appreciate for their reconciliation processes. You can read more about it here: (help.superrare.com).

Emerging Best Practices on SuperRare

• When planning enterprise drops with several stakeholders involved, make sure to clearly define the secondary split logic in your drop's terms and conditions as well as in your smart contracts. This should align with the RarePass approach, and you should also make it clear that sales on platforms not enforcing these splits are off-limits. You can check out the details here.
• If you’re thinking about using Royalty Registry overrides, double-check that your minting path is using SuperRare V2/V3 modules that are compatible with those registry-based overrides. Some tokens might not support rerouting after they’ve been minted, so it’s good to be cautious. For more info on this, visit 7blocklabs.com.

Curve Finance AMM mechanics in 2026: how fees and liquidations actually work

Curve’s mechanics play a crucial role in figuring out how much liquidity you can tap into, what the costs are for trading and borrowing, and how value gets distributed among governance. Here are some key points to keep in mind:

1) V2 CryptoSwap Pools and "Price Scaling"

• So, here’s the scoop on Curve v2: it smartly adjusts to focus liquidity based on an EMA-driven internal oracle--what they call a “price scale.” This nifty feature helps pile up depth around the current price, which really cuts down on slippage for those more volatile pairs. Plus, pool admins have the flexibility to tweak how this works, but keep in mind that there are some DAO-level admin fees involved. This setup is quite different from your typical fixed bonding curves, and it plays a big role in how LP returns stack up and how smoothly the trades go down. Check out the details in the docs!

2) Fee splits and routing to veCRV

So, let’s talk about the fee splits and how they’re routed to veCRV. Traditionally, Curve would take 50% of the pool’s trading fees as admin fees. But now, things have changed a bit. The fees are now bundled together and distributed in crvUSD to veCRV holders each week through the upgraded FeeDistributor. The DAO is still chatting about how to allocate the treasury, including things like slices for community funds. For those who are integrating, this means liquidity programs can work with a fee system that's not only capital-efficient but also flexible in terms of governance. You can find more details here.

3) crvUSD and LLAMMA: Banded Liquidation Instead of Cliffs

• With loans, collateral is spread across a range of 4 to 50 bands. When the oracle price drifts into your band, the AMM starts a soft-liquidation process (basically selling some of that collateral for crvUSD). If the price bounces back, it will de-liquidate, which means buying back the collateral. To keep things on track, arbitrageurs jump in to make sure the AMM price aligns with the oracle’s price by using get_p, and they pay swap fees that help balance out any losses for borrowers. Some key parameters to keep an eye on are fee, admin_fee, and rate (the interest rate). Governance proposals are actively tuning these monetary policy variables, like rate0 and target fractions, to keep the peg stable and manage borrowing demand. You can dive deeper into this here.

4) Practical Loss Math and Mitigation

• The loss-versus-rebalancing (LVR) from soft or de-liquidations can be somewhat balanced out by swap fees. Research from the community on risk suggests that tuning fees--think bumping them from about 0.6% up to around 0.9%--can help cut down on “unnecessary” liquidations while still keeping arbitrage moving smoothly. This approach is a more advanced tool for protocol designers who are looking to incorporate Curve-style liquidations. You can check out more about this here.

Emerging Best Practices on Curve

• When you’re setting up new CryptoSwap pools, make sure you kick things off with realistic volatility assumptions for the initial parameters. Also, don’t forget to think about your admin-fee policy! It should strike a good balance between LP APRs and veCRV incentives. Keep an eye on the ongoing DAO temp checks regarding alternative admin-fee structures for those V2 efficiency pools. You can find more info here.
• For crvUSD credit products, it’s a smart move to pick more bands--like 20 to 30--if you’re anticipating some chop. This helps smooth out rebalancing. On the other hand, if you’re really confident about your collateral, you can stick with fewer bands. Just remember to keep tabs on the rate and any monetary policy proposals! To avoid any nasty “parameter rug” surprises, make sure to disclose how liquidation discounts only update when users interact. You can dive deeper into this here.

Apples-to-apples: royalties vs AMM fees

• Enforceability
  • Rarible on L1/L2: When trades go through Rarible-controlled flows, they enforce royalties. However, other aggregated venues might have their own rules for enforcement. The good news is that Rarible enhances this process with wrappers and registry lookups to help push for enforcement. With the RARI Chain, this gets even better, as it moves enforcement up to the protocol level. (rarible.com)
  • SuperRare: If you're using SuperRare contracts, you're looking at a standard 10% creator royalty. But keep in mind that some external venues might not honor this unless they back the Royalty Registry. (campaigns.superrare.com)
  • Curve: Here’s the deal--Curve operates without royalties. Instead, they focus on offering clear fee parameters and governance-routed admin fees. The great part? These can be modeled accurately in your P&L. (docs.curve.finance)
• Cost Predictability
  • Rarible: The marketplace fee can really add up for lower-priced items, but there are ways to ease the pain, like RARI staking and the community marketplace where fees can be 0%. Plus, the royalties are set by the creators themselves. You can find out more here.
  • SuperRare: They have set splits for creators--85% for primary sales and 90% for secondary, along with a 3% buyer fee. The bright side? If you're into one-of-a-kind art, the curation really helps boost prices. Check it out here.
  • Curve: Costs for liquidity providers and traders can vary based on market conditions and settings. The admin fee is typically set by the DAO, usually around 50% of the trading fee, and it's paid out weekly in crvUSD. For more details, visit here.
• Liquidity effects
  • Rarible and SuperRare: When it comes to liquidity depth, it really depends on how well the markets are connected and the size of the collector base. Rarible’s aggregation makes it easier to fill up order books, while SuperRare’s focus on curation tends to pull in demand for high-value items. (help.rarible.com)
  • Curve: They have this cool structural liquidity setup with gauges, veCRV voting, and extra incentive layers (like Convex) that can really ramp up pool sizes quickly when emissions and gauges are in a good spot. (resources.curve.finance)

Worked examples for decision-makers

1. A consumer brand is gearing up to drop 250k loyalty collectibles, each priced at $20.

• Challenges: With such a low price point, we’re dealing with high volume sales, and there's a strong need to ensure a 5% creator royalty for any resales happening in the brand’s own app.
• How to make it happen:
  • Kick things off with a Rarible-powered community marketplace (where you won’t face any Rarible fees) and set up a small "community fee" of 1-2% to help cover operational costs; make sure to enforce that 5% creator royalty at the collection level. (help.rarible.com)
  • Mint and trade on RARI Chain to turn royalty compliance into protocol rules; include a detailed venue list in your Terms that shows third-party trades avoiding royalties will revert on RARI Chain (and might end up failing elsewhere). (help.rarible.com)
  • If you need to pull in external liquidity, be sure to have EIP-2981 metadata in place and check that your Rarible registry entry is spot-on; don’t forget to run a complete test on a SudoSwap checkout path to ensure that royalty routing is working as intended. (rarible.com)
  • Bottom line: You’ll have a reliable 5% creator royalty, super low marketplace fees, and less leakage for items priced under $100.

1. A fine-art studio dropping 1/1s with an average selling price of $15k

• Constraints: We're talking fewer pieces here, so curation and provenance are key--it's all about those details rather than just scraping by on fees.
• Implementation:
  • Use SuperRare to mint your pieces. This way, you’ll tap into that sweet default 10% royalty and get in front of a curated audience. Just remember to factor in the 3% buyer fee and the 15% cut on the primary sale. You can even create a story around collector incentives by highlighting the new 1% collector royalty from network fees. This can help boost early demand without messing with artist royalties. (help.superrare.com)
  • If you need to set up custom secondary splits for a specific release, take a cue from RarePass on how they structure their terms and contracts. Make it clear that if off-protocol trades don't settle these splits, it could lead to buyer liability. (campaigns.superrare.com)

3) A DeFi Wallet with Built-in Swaps and Credit

• Constraints: We need to strike a balance between tight spreads and being transparent about revenue sharing with our token holders.
• Implementation:
  • Let's integrate Curve v2 CryptoSwap for those volatile pairs where price-scaling can really boost depth. We should set the execution policy to prioritize pools that have solid gauge emissions and recent admin fee realizations to keep slippage in check. You can check out more details here.
  • When it comes to credit, we should embed crvUSD markets with LLAMMA, and default to 20-30 bands for those choppy assets. It'll be key to keep an eye on the rate and monetary policy votes. Also, let's make sure to inform our users that liquidation discounts will update as they interact with the platform, preventing any confusion in the UI. More info is available here.
  • Finally, we need to keep our governance token holders in the loop about how admin fees accumulate. We’ll distribute these fees weekly in crvUSD through the FeeDistributor, referencing the DAO’s current fee allocator policy for full transparency. For the specifics, check this link: FeeDistributor.

Risks and gotchas to budget for

• “Optional royalties” on external venues: Even with registries and wrappers in place, behavior across different venues can sometimes take unexpected turns. If you've made promises to creators, it's best to stick with RARI Chain or keep trading restricted to venues and contracts that enforce royalties. Check it out here.
• Parameter drift in credit markets: The risk/reward of LLAMMA really hinges on the fee and rate. DAO proposals often tweak the baseline rates and peg policies, so it’s smart to keep an eye on those votes and make sure to keep borrowers in the loop about any changes. Dive deeper here.
• Treasury planning: There are some interesting discussions around Curve’s fee allocator that could shift a portion of revenue. It’s a good idea to treat your veCRV income as variable and do some scenario planning to prepare for different outcomes. More details can be found here.

---

Bottom line

• For brands or games that need to ensure creators get paid: jump on Rarible’s community marketplace stack and use RARI Chain to make sure royalties are enforced. Plus, you’ll have clear EIP-2981 data for any transactions that happen across different venues. (help.rarible.com)
• If you run a fine-art studio and want to focus on curation and what collectors want: check out SuperRare. They offer a standard 10% royalty, have a transparent DAO fee model, and their new collector-royalty incentive is perfect for those premium 1/1 pieces. (help.superrare.com)
• If you’re a wallet or protocol that’s all about keeping liquidity efficient and fees clear: Curve’s V2 pools, veCRV-aligned fee routing, and LLAMMA credit mechanics have been tried and true. They’re also adjustable through governance for 2026. (docs.curve.finance)

Choose what works best for you based on how enforceable it is, how the ASP distribution looks, and the liquidity/fee dynamics that align with your KPIs. Once you’ve made your decisions, make sure to document everything in contracts, help center articles, and your Terms so that both operations and legal are on the same page from day one.
