Curve Accuses PancakeSwap of Unauthorized Use of StableSwap Code

Recently, a code usage dispute has erupted in the decentralized finance space, with Curve Finance accusing PancakeSwap of copying its core algorithm, StableSwap technology, without authorization. Curve publicly stated on social media that PancakeSwap directly adopted open-source code from Curve in its newly launched "Infinity StableSwap" upgrade, but failed to comply with the license requirements for proper attribution, constituting a violation of the authorization agreement. StableSwap is an innovative Automated Market Maker (AMM) model launched by Curve in 2020, specifically designed for stablecoins and low-volatility assets. By combining constant product and constant sum curve formulas, it significantly reduces transaction slippage and improves capital efficiency. Due to its excellent performance, this technology has become an industry standard for stablecoin trading in the DeFi News ecosystem. Although its smart contracts are open source, they explicitly require users to retain the original copyright notice and comply with the license terms.

Curve attached code comparison screenshots in its post, showing that PancakeSwap listed itself as the author in the code files, while the core logic was completely inherited from Curve's implementation. Curve emphasized that similar acts of infringement in the past have not only led to legal disputes but also damaged project reputation and hindered technological iteration. PancakeSwap responded quickly after the incident was exposed, stating that it would proactively contact the Curve team for communication and seek a proper solution. Curve welcomed this and emphasized in a subsequent response:

"Cooperative construction is better than conflict." Currently, both parties have expressed a willingness to reconcile. Curve has made it clear that as long as PancakeSwap is willing to sign a legal authorization agreement, correctly attribute the source, and follow technical specifications, it can still legally use StableSwap technology and jointly promote the optimization of the stablecoin trading experience. This incident once again highlights the importance of open-source protocols in the blockchain ecosystem. Although the code is public, compliant use is still the cornerstone of sustainable project development.
