Upgrade Process

1

Proposal submitted by team

The team submits an upgrade proposal to the governance/upgrade process.

2

Multi-sig approval (3-of-5)

The proposal requires approval from at least 3 of the 5 designated multi-sig signers.

3

48-hour time-lock begins

Once approved, a 48-hour time-lock starts before execution is allowed.

4

Community notified

The community is notified about the pending upgrade during the time-lock period.

5

Upgrade executed after time-lock

After the time-lock elapses (and assuming no intervention), the upgrade is executed.
