Important

"This culture of making excuses for "decentralized" applications with closed-source smart contracts needs to stop.

Important

Your application is not a DApp if your smart contracts cannot be independently reviewed by the public for backdoors / master-keys. " - @phil_uplc twitter

Dishonourable Mentions

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.

Some honourable mentions

• Indigo is a fully-fledged protocol, and one of the largest which is also completely open-source.
• LenFi v1 has been open-source and has already open-sourced v2 before launch.
• Spectrum-Finance (soon to be splash) is probably the only DeX which is actually decentralised.
• Danogo is a cool project, would like to see more bonds some day.
