Decentralized exchange Curve Finance has accused rival DeFi platform PancakeSwap of using its proprietary StableSwap code without authorization, sparking a dispute over licensing and intellectual property in the decentralized finance sector.
The allegation was made on March 6 in a post on X, where the Curve team claimed that PancakeSwap’s recently introduced StableSwap functionality appears to rely on Curve’s code despite not having permission to do so.
Dear @PancakeSwap. Looks like you copied our code without asking. It is violation of its license. Not only it is illegal: historically it showed to be unwise for those who did it this way in other regards.In any case. If you want to enjoy using stableswap without legal… https://t.co/HkWWAQGXfs pic.twitter.com/UbIi7dpfkB

Curve said the move represents a direct violation of the licensing terms attached to its StableSwap technology.
StableSwap is a core innovation developed by Curve that allows decentralized exchanges to provide highly efficient trading between stablecoins and assets with similar prices.
By reducing slippage and improving liquidity efficiency, the algorithm has become a foundational component of many DeFi platforms that focus on stablecoin trading.
According to Curve, projects interested in using the technology must comply with the licensing framework governing the StableSwap code.
The team warned that copying or replicating financial infrastructure without proper authorization could expose projects to legal risks and potential technical vulnerabilities.
The controversy emerged after PancakeSwap introduced a new trading feature as part of its platform upgrades designed to improve stablecoin swaps and liquidity pools.
Curve claims that the implementation mirrors aspects of its StableSwap model, raising concerns about whether the code was replicated without adherence to the license terms.
Curve also highlighted broader implications for the decentralized finance ecosystem, emphasizing that open-source innovation still relies on respecting licensing agreements and developer rights.
The team argued that ignoring such rules could discourage future innovation and collaboration in the industry.
In response to the allegations, PancakeSwap indicated that it would engage with the Curve team to discuss the matter and clarify the situation.
While no legal action has been announced so far, the dispute underscores growing tensions over intellectual property and code reuse within the rapidly evolving DeFi landscape.
The outcome of the disagreement could set an important precedent for how DeFi projects handle licensing and collaboration in the future.
