There was an interesting drama that took place in the DeFi ecosystem a few weeks ago. Curve Finance officially accused PancakeSwap of using their StableSwap code without following the proper license. The accusation surfaced publicly in early March and immediately drew attention.

So here’s the story. Curve developed StableSwap as a solution for more efficient stablecoin trading. This technology uses a special crypto formula that combines a constant product curve with a constant sum curve to reduce slippage. Well, when PancakeSwap launched their Infinity upgrade, Curve noticed that the logic from their system was used in PancakeSwap’s cross-chain swap feature. The problem isn’t just about the code used, but PancakeSwap also didn’t follow the attribution rules required by Curve’s open-source license. Curve even shared a code comparison showing PancakeSwap appeared as the author in several files, even though the core logic originated from Curve’s design.

PancakeSwap responded quite quickly. They acknowledged the dispute and stated they are willing to have a direct discussion with Curve to resolve the issue. This response is quite positive considering Curve also showed openness to collaboration rather than conflict. But until now, there has been no public update on how the resolution will proceed.

What’s interesting about this case is the highlight on license responsibility within the DeFi ecosystem. Many DeFi developers do reuse existing code to speed up development, which is normal. But licenses still have rules, especially regarding attribution and compliance. This isn’t a trivial matter because there are serious security risks involved.

Curve warned that improper implementation of StableSwap could open security vulnerabilities. They pointed to previous incidents like Saddle Finance getting hacked in 2022 due to weak swap logic, or Balancer losing $116 million in 2025 from an AMM exploit. This shows that crypto formulas and complex liquidity mechanisms require deep technical understanding. Just copy-pasting without understanding can have fatal consequences.

PancakeSwap Infinity itself is actually a pretty solid upgrade. They added cross-chain swaps, dynamic fees, programmable hooks for liquidity pools, and on-chain limit orders. Plus, they reduced pool creation costs by up to 99%, making it easier for developers to launch pools. When deployed on Base in July, trading fees for ETH and ERC-20 pairs dropped by 50%. But all these advanced features need to be implemented correctly in terms of security and licensing.

This case serves as an important reminder for the entire DeFi ecosystem about the importance of respecting open-source licenses and conducting proper due diligence when utilizing existing technology. It’s not just about legal compliance, but also about security and long-term credibility.
