So there's an interesting drama unfolding in the DeFi world. Curve Finance recently accused PancakeSwap of using its StableSwap code without proper permission. This issue started gaining public attention in early March, and now it has become a key discussion about licensing and attribution in open-source protocol development.

For those who don't know, StableSwap is an innovation by Curve designed to enable efficient trading between stablecoins and assets with strong pegs. What makes this technology unique is its crypto formula that combines the constant product curve and the constant sum curve. This formula significantly reduces slippage compared to traditional AMMs, which is why many protocols are interested in adopting it.

Now, here’s the problem. Curve claims that PancakeSwap integrated logic from its StableSwap system into their Infinity upgrade without following the applicable licensing terms. The Curve team showed detailed code comparisons, where some files list PancakeSwap as the registered author, even though, according to Curve, the core logic originates from their StableSwap design. This is not just a technical issue but also a legal and ethical matter within the open-source community.

Why is this important? Curve emphasizes that StableSwap requires deep technical understanding to deploy safely. Incorrect implementation could open security vulnerabilities in the liquidity pool. They also remind that this complex crypto formula demands specialized expertise. If not done correctly, the results could be disastrous.

History proves this. Saddle Finance was hacked in 2022 due to weaknesses in their swap logic implementation. More recently, Balancer lost about $116 million in 2025 due to an exploit. These two cases show how serious the risks are when protocols copy crypto formulas without full understanding.

PancakeSwap responded quickly. They acknowledged the dispute and stated they are willing to contact Curve Finance directly for discussion. This response shows good faith to resolve the issue through dialogue rather than confrontation. Curve also expressed openness to collaboration.

Meanwhile, the PancakeSwap Infinity upgrade itself is quite significant. The platform now supports cross-chain swaps, dynamic fees, and programmable smart contract hooks for liquidity pools. They also reduced pool creation costs by up to 99 percent. Infinity is already deployed on BNB Chain, Arbitrum, and Base, with the Base implementation cutting trading costs for Ether and ERC-20 token pairs by half.

But this dispute serves as an important reminder for the DeFi ecosystem. Although the code is open-source, licenses are still binding. Developers often reuse existing code to speed up development, but that doesn’t mean they can ignore attribution and compliance. This remains an ongoing challenge in the rapidly evolving DeFi space, where innovation and legal responsibility must go hand in hand. Hopefully, both teams can find a fair and transparent solution.
