FAQ

1. Can third-party contract incompatible upgrade be implemented without Dao?

   Incompatible upgrades can be achieved through a two-stage commit upgrade, but the current command line does not yet support direct two-stage upgrades.

2. What if BACKWARD_INCOMPATIBLE_MODULE_UPDATE error occurs when redeploying tokenswap?

   Error due to incompatibility between front and back，add the --ignore-breaking-changes parameter and rerun.

3. Is there a way to force deploy module?

   Without considering compatibility, the deploy module can be submitted in two phases.
