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

Short description: A practical, up-to-date comparison of how Rarible and SuperRare implement and enforce NFT royalties—and how those economics stack up against Curve Finance’s AMM fee and LLAMMA liquidation mechanics—so you can pick the right stack for your 2026 NFT or DeFi product roadmap. (help.rarible.com)

Why this comparison matters in 2026

In the last 24 months, the royalty question moved from “policy” to “protocol” for some stacks, while AMMs kept iterating on capital efficiency and fee routing. As a result:

If you need guaranteed recurring revenue from secondary NFT trades, your venue and chain choice now directly determines whether royalties are best-effort or enforced at the protocol layer (e.g., RARI Chain). (help.rarible.com)
If you want predictable take rates and liquidity recycling, AMM mechanics (fee splits, admin-fee routing, oracle design, liquidation behavior) will often have a bigger P&L impact than headline “platform fees.” (docs.curve.finance)

Below is a ground-level comparison with concrete integration tactics for startups and enterprise innovation teams.

Snapshot: what each platform actually does with fees/royalties

Rarible
- Service fee: regressive per side, from 0.5% (>$4,000) to 7.5% (<$100). Community marketplaces built with Rarible’s editor are 0% Rarible fee; project-defined “community fees” are optional. Aggregated listings use a similar 0.5–7.5% scale. Locking RARI can zero out Rarible.com fees. (help.rarible.com)
- Royalties: creator-defined at mint or collection level; EIP-2981-compatible on ETH and Polygon; Rarible enforces for native listings and routes royalties for many aggregated venues via registry/wrappers. (help.rarible.com)
- Hard-enforcement option: on RARI Chain, royalties are embedded at the sequencer/node level—transfers that skip the configured royalty revert. (rari.foundation)
SuperRare
- Fees: primary sale 85% artist / 15% to SuperRare DAO; secondary 90% seller / 10% artist royalty; plus 3% buyer fee to the DAO. DAO treasury address:
```
0x860a80d33e85e97888f1f0c75c6e5bbd60b48da9
```
  . (help.superrare.com)
- Royalty defaults and registry: platform-level 10% royalty for protocol-invoked sales; newly minted works default to 10% in Royalty Registry (adjustable per terms). (campaigns.superrare.com)
- New incentive: “Collector Royalties” grant the first collector a 1% royalty on the first qualifying secondary sale, paid from the network fee (not the artist’s 10%); external coverage notes a halving schedule thereafter. (medium.com)
Curve Finance (AMM + crvUSD)
- Pools (V2 CryptoSwap): adaptive “price scaling” concentrates liquidity around an EMA-style internal oracle; admin fees set by DAO; fee routing via updated burners and distributors to veCRV in crvUSD. (docs.curve.finance)
- crvUSD’s LLAMMA: liquidation via bands/ticks (4–50), with soft-liquidation/de-liquidation driven by arbitrage between the AMM’s internal price and an oracle; explicit fee, admin_fee, and interest rate parameters govern borrower P&L. (docs.curve.finance)
- Fee distribution: 50% of pool trading fees to veCRV (admin fee share), with weekly conversions/distributions in crvUSD under the new FeeDistributor. (resources.curve.finance)

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

Rarible now operates on three layers that matter for royalties:

Rarible.com and native listings

Creators can set up to 50% royalties per item or at collection level; EIP-2981 support on ETH/Polygon. Enforcement is guaranteed for trades executed on Rarible. (help.rarible.com)

Aggregated liquidity

Rarible aggregates orders from major venues and community marketplaces and respects the royalty configuration from the originating marketplace or from Rarible’s royalty registry, including a wrapper approach for SudoSwap-style AMMs. In practice, this means the checkout logic on Rarible remits creator fees even when source venues treat royalties as optional. Integration teams must still ensure the originating collection has properly configured creator fee fields on X2Y2/LooksRare, or EIP-2981/registry data for SudoSwap, etc. (help.rarible.com)

RARI Chain (Ethereum L3 powered by Arbitrum tech)

RARI Chain embeds royalty checks at the sequencer level: a transfer that attempts to bypass the configured royalty payment reverts, moving royalties from “policy” to “protocol.” For startups needing guaranteed rev-share for brand IP, this is the cleanest on-chain enforcement path available now. (rari.foundation)

Fee reality check for 2026 launches

If your ASP is <$400, Rarible’s regressive fee can be meaningfully higher than for >$4,000 items unless you lock RARI or transact via a 0% community marketplace you control. For enterprise programs (e.g., ticketing, loyalty collectibles) where many items are < $100, budget for a 7.5% per-side fee unless you take mitigating steps below. (help.rarible.com)

Emerging best practices on Rarible

For game/NFT-fi launches bridging SudoSwap liquidity, publish your collection royalty rate via EIP-2981 and register it in Rarible’s royalty registry; test a SudoSwap purchase flow on a staging marketplace to verify the wrapper routes the creator fee. (rarible.com)
If royalties are a must-have promise in your brand/legal, mint and trade on RARI Chain. For multi-venue trading, bridge assets in a way that preserves ERC-2981 metadata and clearly disclose which venues guarantee enforcement. (help.rarible.com)

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

SuperRare remains the reference curated venue for 1/1 art with well-documented economics:

Primary sales route 85% to artists and 15% to the DAO; secondary sales automatically send 10% to the original artist, with a 3% buyer fee on all sales to the DAO treasury. These are enforced for trades invoking SuperRare protocol contracts. (help.superrare.com)
The Terms specify defaulting newly minted works to a 10% royalty in the Royalty Registry. If your workflow requires adjusting post-mint, confirm contract/version compatibility before deployment. (campaigns.superrare.com)
The “Collector Royalties” program grants the first collector a 1% royalty funded from the network fee on the first qualifying secondary trade where they’re not a counterparty; third-party coverage notes a halving pattern thereafter. This can stimulate primary demand without touching the artist’s 10%. (medium.com)
Treasury transparency: the DAO’s fee destination is public (
```
0x860a80d33e85e97888f1f0c75c6e5bbd60b48da9
```
), which many enterprise finance teams appreciate for reconciliation. (help.superrare.com)

Emerging best practices on SuperRare

For enterprise drops with multiple stakeholders, codify secondary split logic in your drop’s T&Cs and smart contracts, mirroring the RarePass approach, and explicitly restrict sales on venues that don’t enforce your splits. (campaigns.superrare.com)
If you intend to rely on Royalty Registry overrides, verify whether your minting path uses SuperRare V2/V3 modules compatible with registry-based overrides; some tokens may not support post-mint rerouting. (7blocklabs.com)

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

Curve’s mechanics determine how much liquidity you can source, what trading/borrowing costs look like, and how value is shared with governance. Key realities:

V2 CryptoSwap pools and “price scaling”

Curve v2 adaptively centers liquidity around an EMA-driven internal oracle (“price scale”), concentrating depth near the current price to reduce slippage for volatile pairs. Pool admins can parameterize behavior; DAO-level admin fees apply. This differs from fixed bonding curves and affects LP returns and trade execution quality. (docs.curve.finance)

Fee splits and routing to veCRV

Historically, Curve set 50% of pool trading fees as admin fees; under the current system, fees are consolidated and distributed in crvUSD to veCRV holders weekly via an upgraded FeeDistributor. DAO discussions continue around treasury allocation (e.g., community fund slices). For integrators, this means liquidity programs interact with a fee system that’s both capital-efficient and governance-tunable. (resources.curve.finance)

crvUSD and LLAMMA: banded liquidation instead of cliffs

Loans allocate collateral across 4–50 bands. When oracle price enters your band range, the AMM soft-liquidates (sells collateral for crvUSD); when price recovers, it de-liquidates. Arbitrageurs keep the AMM price aligned via
```
get_p
```
vs oracle, paying swap fees that offset borrower losses. Critical parameters:
```
fee
```
,
```
admin_fee
```
, and
```
rate
```
(interest). Governance proposals actively tune monetary policy variables like
```
rate0
```
and target fractions to stabilize peg and borrowing demand. (docs.curve.finance)

Practical loss math and mitigation

Loss-versus-rebalancing (LVR) from soft/de-liquidations can be partially offset by swap fees; community risk research suggests fee tuning (e.g., from 0.6% to ~0.9%) can reduce “unnecessary” liquidations while preserving arbitrage throughput. This is an advanced lever for protocol designers embedding Curve-style liquidations. (gov.curve.finance)

Emerging best practices on Curve

For new CryptoSwap pools: set initial parameters with realistic volatility assumptions and plan an admin-fee policy that balances LP APRs with veCRV incentives; watch ongoing DAO temp checks on alternative admin-fee structures for V2 efficiency pools. (resources.curve.finance)
For crvUSD credit products: choose more bands (e.g., 20–30) to smooth rebalancing if you expect chop; fewer bands for high-conviction collateral. Monitor
```
rate
```
and monetary policy proposals; avoid “parameter rug” surprises by disclosing how liquidation discounts update only on user interaction. (docs.curve.finance)

Apples-to-apples: royalties vs AMM fees

Enforceability
- Rarible on L1/L2: royalties enforced when trade executes through Rarible-controlled flows; aggregated venues may still gate enforcement to their own policies—but Rarible adds wrappers/registry lookups to push enforcement. RARI Chain upgrades this to protocol-level enforcement. (rarible.com)
- SuperRare: 10% creator royalty is protocol-default for trades invoking SuperRare contracts; external venues may not honor it unless they support Royalty Registry. (campaigns.superrare.com)
- Curve: no royalties—just transparent fee parameters and governance-routed admin fees shared with veCRV, which can be modeled precisely in P&L. (docs.curve.finance)
Cost predictability
- Rarible: regressive marketplace fee can be high for low-priced items; mitigations exist (RARI staking; 0% community marketplace). Royalties are creator-configured. (help.rarible.com)
- SuperRare: known splits (85/15 primary, 90/10 secondary) + 3% buyer fee; upside is curation-driven price realization for 1/1 art categories. (help.superrare.com)
- Curve: LP/trader costs respond to volatility and parameterization; admin fee is DAO-configured (commonly 50% of trading fee) and routed weekly in crvUSD. (resources.curve.finance)
Liquidity effects
- Rarible and SuperRare: liquidity depth depends on cross-market aggregation and collector base. Rarible’s aggregation helps fill orderbooks; SuperRare’s curation can concentrate high-value demand. (help.rarible.com)
- Curve: structural liquidity via gauges, veCRV voting, and external incentive layers (e.g., Convex) can scale pools quickly if emissions/gauges are favorable. (resources.curve.finance)

Worked examples for decision-makers

A consumer brand launching 250k loyalty collectibles with a $20 ASP

Constraints: low ticket size, high volume, strong need to guarantee a 5% creator royalty for secondary markets in the brand’s own app.
Implementation:
- Launch a Rarible-powered community marketplace (0% Rarible fee) and set a 1–2% “community fee” to fund ops; enforce 5% creator royalties at collection level. (help.rarible.com)
- Mint and transact on RARI Chain to convert royalty compliance into protocol rules; publish an explicit venue list in your Terms showing that third-party trades which bypass royalties will revert on RARI Chain (and may fail elsewhere). (help.rarible.com)
- If you must aggregate external liquidity, ensure EIP-2981 metadata is present and the Rarible registry entry is correct; test a SudoSwap checkout path end-to-end to confirm wrapper-based royalty routing. (rarible.com)
- Net effect: predictable 5% creator royalty, near-zero marketplace fee, minimized leakage for sub-$100 items.

A fine-art studio releasing 1/1s with a $15k ASP

Constraints: fewer items, curation and provenance matter more than the last 50 bps of fee.
Implementation:
- Mint on SuperRare to access the default 10% royalty and curated demand. Budget for the 3% buyer fee and 15% primary split; add a collector-incentive narrative leveraging the new 1% collector royalty from network fees to accelerate early demand without touching artist royalties. (help.superrare.com)
- If you need custom secondary splits for a particular drop, mirror RarePass’s approach in your T&Cs and contracts, and state that off-protocol trades that don’t settle the split may create buyer liability. (campaigns.superrare.com)

A DeFi wallet adding built-in swaps and credit

Constraints: must balance tight spreads with transparent revenue share to token holders.
Implementation:
- Integrate Curve v2 CryptoSwap for volatile pairs where price-scaling improves depth; set execution policy to prefer pools with healthy gauge emissions and recent admin-fee realizations to reduce effective slippage. (docs.curve.finance)
- For credit, embed crvUSD markets with LLAMMA; default to 20–30 bands for choppy assets, monitor
```
rate
```
  and monetary policy votes; document to users that liquidation discounts update on interaction to avoid UI misunderstandings. (docs.curve.finance)
- Communicate to governance token holders how admin fees accrue and distribute weekly in crvUSD via FeeDistributor, with references to the DAO’s current fee allocator policy. (docs.curve.finance)

Integration checklists (copy/paste for your project plan)

Rarible/RARI Chain
- Set EIP-2981 royalties at mint; register in Rarible’s royalty registry. (help.rarible.com)
- For community marketplace, confirm 0% Rarible fee and set your own community fee (treasury wallet specified). (help.rarible.com)
- If aggregating X2Y2/LooksRare, configure their creator-fee address fields; test aggregated checkouts to confirm royalties are charged. (rarible.com)
- If royalties must be guaranteed, deploy on RARI Chain and publish venue-compatibility guidance for users. (help.rarible.com)
SuperRare
- Align financial model with 85/15 primary, 90/10 secondary, and 3% buyer fee. (help.superrare.com)
- Validate Royalty Registry behavior for your minting path; some tokens may not support overrides. (7blocklabs.com)
- Decide whether to lean into Collector Royalties to prime early demand. (medium.com)
Curve Finance
- For V2 pools, evaluate price-scaling parameters and target admin-fee policy; monitor DAO threads on alternative fee structures. (docs.curve.finance)
- For crvUSD, choose band count by expected volatility; track rate policy proposals and liquidation discount changes. (docs.curve.finance)
- Communicate fee distribution in crvUSD to token holders and treasury, and set internal accounting to weekly epochs. (docs.curve.finance)

Risks and gotchas to budget for

“Optional royalties” on external venues: even with registries/wrappers, cross-venue behavior can drift. If you’ve made public commitments to creators, prefer RARI Chain or isolate trading to royalty-enforcing venues and contracts. (help.rarible.com)
Parameter drift in credit markets: LLAMMA risk/reward depends on
```
fee
```
and
```
rate
```
. DAO proposals sometimes adjust rate baselines and peg policy; you should watch votes and communicate changes to borrowers. (docs.curve.finance)
Treasury planning: Curve’s fee allocator debates could redirect a slice of revenue; treat veCRV income as variable and scenario-plan. (gov.curve.finance)

Bottom line

If you’re a brand or game that must guarantee creator revenue: build on Rarible’s community marketplace stack and transact on RARI Chain for protocol-enforced royalties, with clear EIP-2981 data for any cross-venue flows. (help.rarible.com)
If you’re a fine-art studio optimizing for curation and collector behavior: SuperRare’s default 10% royalty, transparent DAO fee model, and new collector-royalty incentive are aligned with premium 1/1 positioning. (help.superrare.com)
If you’re a wallet/protocol prioritizing liquidity efficiency and fee transparency: Curve’s V2 pools, veCRV-aligned fee routing, and LLAMMA credit mechanics are battle-tested and governance-tunable for 2026. (docs.curve.finance)
