So far, 2020 has been a great year for decentralized finance [DeF. This also goes for the several DeFi platforms including Yearn. Finance. But the same cannot be said for it Creator. Yes, we are talking about Andre Cronje who found himself in between a tussle over an incomplete DeFi platform for which the developer not only faced severe backlash from the community members but could also see a potential legal notice in the coming days.
Unpacking some topics that I have been trying to consolidate for a few weeks now; https://t.co/2wVt6sBq8D

In the latest blog post, Cronje broke his silence and stated that he builds for developers and not speculators. He further quashed all the reports saying that he quit DeFi because of the Eminence.Finance (EMN) exploitation.
“Test in Prod”
‘Test in Prod’ essentially means ‘testing is production’ which lets a DevOps team prepare for possible bugs. It is common for bugs to end up in production. Cronje admitted that this popular statement that he frequently uses, and something that is written on his Twitter Handle’s Bio, backfired. He also clarified that he used this phrase to deter people from just using systems without investigation and went on to explain that the ‘test in prod’ approach consists of six stages.
Stage 1 refers to local tests, where everything is functional and works as planned.
Then comes Stage 2, which involves interaction testing, this makes sure that everything functions from a 1 user interaction perspective.
The 3rd Stage is for composite testing, which compares interaction between multiple parties.
Stage 4 is the ‘fake prod’ stage which involves replication of ETH mainnet and the deployment of contracts to check the interaction.
Lastly, Stage 6, is for “prod deployments” and coincides with user interface [UI] and other documentation [such as medium articles, etc.].
Notably, Eminence was exploited in stage 5. Cronje’s clarification comes days after a group of investors revealed crowdfunding a lawsuit against Yearn.Finance Founder over the unreleased and unfinished Eminence protocol and its subsequent hack. The group had earlier revealed,
“As a way to thank you for your donation, we will take a snapshot at the end of the crowdfunding campaign, and airdrop 50% of the supply of a fork of YFI to donators. The other 50% of the supply will be airdropped to the victims of the EMN scandal. We will create a new DeFi ecosystem but without the bad actors.”
