Tracking what projects on Cardano are open source & decentralised
To contributors: Please help me fill this out with accurate data.
[!IMPORTANT]
"In the real world, you would never ask someone to sign a contract that they cant read. " - @phil_uplc twitter
[!IMPORTANT]
"This culture of making excuses for “decentralized” applications with closed-source smart contracts needs to stop.
[!IMPORTANT]
undefinedYour application is not a DApp if your smart contracts cannot be independently reviewed by the public for backdoors / master-keys. " - @phil_uplc twitter

“All closed source code can have some backdoors to steal your funds” - @notjuve twitter
| Name | Logo | Why |
|---|---|---|
| Liqwid Finance | advertises as “DeFi” (decentralised finance) despite not open-sourcing their main protocol contracts. | |
| VyFi | ![]() |
to my knowledge operates as DeX but has not open-sourced ther main contracts. |
| Optim Finance | calls itself “decentralization advocates” despite not open-sourcing their main protocol contracts. | |
| WingRiders | ![]() |
also closed source “DeX”. |
| SundaeSwap | ![]() |
build “decentralized software” however do not meet the most basic tenant of decentralisation |
[!NOTE]
Sundae & Liqwid Labs both make significant OS contributions however it is a smudge against them that they do not open-source their protocol smart contracts.
