Controversy and Split
According to court documents, as early as October 2017, Hemachandra offered to purchase Monahan's stake in the company for $1 million only if he could see all financial documentation of MEW first. On October 5, Hemachandra's attorney, William Yen, wrote, "It seems unlikely that our clients will come to an agreement that would allow MEW to exist with both of them as equal owners." 
In December, Hemachandra petitioned the Court to direct Monahan and MEW to allow for the inspection and copying of "all books, records, and financial documents of MEW." Public records show that a hearing date is set for March 27, 2018. 
In February 2018, the MyEtherWallet Twitter account was changed to being MyCrypto due to a fallout with Taylor's original Co-Founder, Kosala Hemachandra.  The swift change caused alarm amongst the Ethereum community, with people calling Taylor's action "amateurish."  
Taylor and the team that followed her to MyCrypto contend that Hemachandra had not been active in coding MyEtherWallet for the past six months.  They say that his lack of involvement meant the MyEtherWallet could no longer evolve and led to the decision to launch MyCrypto.
