Refactor compass upgrade process #1802

Closed byte-bandit closed 2 months ago

byte-bandit commented 3 months ago

Possible state desync during compass upgrade:

gravity nonce (needs to be exactly +1 and is set at ctor input)
funds & books (changed with every SLC, but will be transferred)

New approach to ensure we don't block ourselves and lose state / funds:

request to upload a new smart contract
drain queues
block adding messages for the chain
deploy contract
transfer ERC20 tokens
monitor and retrigger if needed
transfer books
monitor and retrigger if needed
switch contract
enable message adding again
