Curve Finance claims PancakeSwap copied its StableSwap code

Curve Finance has accused PancakeSwap of copying parts of its StableSwap code without permission, calling the use a violation of the software license. The allegation was posted on X on March 6 and included a screenshot that Curve said highlighted the code in question, with file attribution listing PancakeSwap as the author despite the logic originating from Curve’s StableSwap system.

StableSwap is one of Curve’s main innovations: an automated market maker model that allows low-slippage swaps between stablecoins and tightly pegged assets by blending constant-product and constant-sum curves. Curve’s smart contracts are open source, but the license requires proper attribution and compliance.

The team warned that directly copying or improperly modifying StableSwap code can create technical risks and has caused problems for forks in the past. PancakeSwap responded shortly after the post, saying its team would contact Curve to discuss the matter.
