Curve Finance Accuses PancakeSwap of Unlicensed Use of StableSwap Code
April 30, 2026 – Crypto News Desk
The development team behind Curve Finance, a leading decentralized finance (DeFi) protocol specialized in low‑slippage stablecoin swaps, has publicly alleged that PancakeSwap – the most‑used decentralized exchange (DEX) on the BNB Chain – incorporated Curve’s “StableSwap” technology into the latest version of its platform, PancakeSwap Infinity, without obtaining the required licence.
What happened
In a series of posts on X (formerly Twitter), Curve’s team pointed out that PancakeSwap’s newest DEX iteration is leveraging the StableSwap algorithm, which underpins Curve’s high‑efficiency stablecoin and tightly‑pegged‑asset swaps. The posts warned that using this proprietary code without a proper agreement could expose PancakeSwap to legal risk.
Curve offered a straightforward remedy: projects that wish to use StableSwap should reach out to negotiate a licence or a collaboration agreement. “If you want to enjoy using StableSwap without legal problems and to borrow some of our expertise to keep users SAFU, you still can contact us for licensing and collaboration,” the Curve team wrote.
PancakeSwap’s response
PancakeSwap’s representatives replied that they would get in touch with Curve to discuss the matter, emphasizing a preference for a cooperative approach: “Indeed, better to be friends and build together.” As of publication, neither side has confirmed a formal settlement or licensing deal, and attempts by Cointelegraph to obtain additional comment went unanswered.
Why the dispute matters
The episode underscores two recurring challenges in the rapidly evolving DeFi ecosystem:
-
Intellectual‑property enforcement – Open‑source and licensed code coexist in DeFi, but the line between permissible reuse and infringement can be blurry. Protocols that rely on proprietary algorithms must navigate licensing terms to avoid potential litigation.
- Security implications – Curve highlighted the need for “deep StableSwap expertise” when integrating swap functionality, citing notable incidents such as the 2022 Saddle Finance hack and the $116 million Balancer exploit in 2025. Both attacks were linked to vulnerabilities in swap‑related smart‑contract code, illustrating that improper implementation can jeopardize user funds.
Background on PancakeSwap Infinity
PancakeSwap’s Infinity upgrade, launched in April 2025, introduced a suite of new features:
- Cross‑chain support – Availability on Arbitrum, BNB Chain, and later Base (an Ethereum L2), enabling users to move assets across multiple ecosystems.
- Hooks architecture – Plug‑in contracts that allow pool creators to customize fee structures, rebates, and on‑chain limit orders.
- Reduced pool creation costs – Fees were slashed by up to 99 %, aiming to lower entry barriers for liquidity providers.
The upgrade also promoted “one‑click” cross‑chain swaps and promised up to a 50 % reduction in trading fees when swapping ETH against ERC‑20 tokens on Base.
Analysis
The licensing dispute could evolve in several directions:
| Scenario | Likelihood | Potential Impact |
|---|---|---|
| Licensing agreement reached – PancakeSwap pays a fee and receives technical support from Curve. | Moderate – Both parties have expressed willingness to collaborate. | Minimal disruption; could lead to tighter interoperability standards across DEXs. |
| Prolonged negotiations – No immediate resolution, but both platforms continue operating. | High – Legal processes in the DeFi space are often slow. | Ongoing uncertainty; may prompt other projects to review their own code dependencies. |
| Litigation – Curve files a lawsuit or initiates a formal claim. | Low – Litigation is rare and costly in the decentralized arena, but not impossible. | Could set a precedent for IP enforcement in DeFi, potentially prompting more rigorous licensing practices. |
Regardless of the outcome, the incident serves as a reminder that DeFi developers must balance rapid innovation with due diligence on code provenance and security audits. As DEXs increasingly incorporate sophisticated swapping mechanisms, the demand for auditable, licensed code—and for expertise on safe implementation—will likely rise.
Key Takeaways
- Curve Finance alleges that PancakeSwap Infinity uses Curve’s StableSwap code without a licence.
- Curve has opened the door for a licensing or collaborative arrangement; PancakeSwap says it will reach out.
- The dispute highlights the growing need for clear IP policies and robust security reviews in DeFi.
- Past high‑profile exploits (Saddle 2022, Balancer 2025) are cited as cautionary examples of swap‑related vulnerabilities.
- PancakeSwap Infinity, with its cross‑chain capabilities and customizable “hooks,” continues to expand its market share while navigating the legal complexities of code reuse.
The situation remains fluid, and stakeholders will be watching closely for any formal agreement or legal development that could shape how DeFi protocols share and protect their intellectual assets.
