So there is an interesting drama unfolding in the DeFi ecosystem lately. Curve Finance has formally accused PancakeSwap of using its StableSwap code without following the proper licensing requirements. This dispute first appeared publicly around early March via X, and since then it has become a fairly serious topic of discussion within the community.

For those who aren’t familiar, StableSwap is a system developed by Curve to enable stablecoin trading with minimal slippage. Its technology combines two different crypto formulas: a constant product curve and a constant sum curve. This combination creates a more efficient automated market maker specifically for assets with tight pegs. Curve believes that PancakeSwap integrated the logic from this system into their Infinity upgrade without proper attribution.

PancakeSwap Infinity itself is a fairly significant upgrade. They rolled out this feature on BNB Chain and Arbitrum around April 2025, adding cross-chain swaps, programmable smart contract hooks, and an onchain limit order system. Each feature is designed to support more sophisticated liquidity strategies. They also reduced pool creation costs by up to 99 percent, which makes it easier for developers to launch liquidity pools. Then in July 2025, PancakeSwap brought this system to the Base layer-2, which they claim can reduce trading costs for Ether pairs by up to 50 percent.

Curve presented a detailed code comparison, highlighting the parts they claim are implementations of their crypto formulas and StableSwap logic. They argue that even though Curve’s smart contracts are open source, the license still requires proper attribution and compliance with the existing terms. The Curve team also emphasized that PancakeSwap appears as the author in several files, even though that logic originally came from their original design.

PancakeSwap responded quickly and showed readiness to discuss directly with Curve. The decentralized exchange said it would contact Curve Finance to resolve this issue. Curve also indicated openness to collaboration rather than an ongoing conflict. To date, neither team has issued additional significant statements.

There is one thing that makes this worth paying attention to: Curve has warned about security risks associated with improperly integrating code. They point out that some previous DeFi platforms suffered serious exploits due to incorrect modifications to their liquidity algorithms. Saddle Finance was hacked in 2022 related to weaknesses in swap logic, and Balancer lost hundreds of millions due to exploits of their automated market maker. Curve argues that StableSwap requires deep technical understanding, and incorrect implementation could expose liquidity pools to attacks.

This dispute actually highlights a bigger challenge within the DeFi ecosystem. Developers often reuse existing code to accelerate product development, but licenses still require compliance even when projects share technology publicly. This serves as a reminder that in the open-source crypto world, attribution and legal compliance still matter. As DeFi continues to grow, issues like this may keep emerging—especially when projects adopt crypto formulas and technologies from other protocols without clear coordination.
