### 2023.04.23 (2023-04-23)
|
||||
|
||||
Did:
|
||||
|
||||
* Single withdrawals working, this means multiple ones are also a given but need to test.
|
||||
* Event emitting, core is an event emitter such that implementors will have an easier time using it.
|
||||
* Relayer also works I guess but sometimes refuses connection?
|
||||
|
||||
Next:
|
||||
|
||||
* Clean up / create / add scripts for inspecting and synchronizing cache since doing over tests is horrible.
|
||||
* Need a few more tests but we can move on to monorepo finally!!!!
