:: L1 contract changes:

:: switched back
|
|
:: - Enforce that once spawn proxy is set to deposit address, you can't
|
|
:: spawn children
|
|
:: - Possibly the same for approveForAll
|
|
:: - Enforce that only ownership key can set spawn proxy to rollup.
|
|
:: maybe not though
|
|
:: - Disallow depositing galaxy to L2
|
|
:: - When depositing, clear proxies (maybe require reset)
|

:: - Maybe require that we're not depositing from a contract?
