DEFAULT_ADMIN_ROLE is only granted inside initialize2, but the repository’s deploy flow still initializes EXA with only initialize (see deploy/EXA.ts), so fresh deployments/upgrades end up with no admin account able to grant BRIDGE_ROLE. In that state, all new bridge mint/burn entry points guarded by onlyRole(BRIDGE_ROLE) are unusable until an extra manual upgradeAndCall(..., initialize2(...)) step is performed.
Useful? React with 👍 / 👎.

On chain 10, initialize mints the full 10M supply to msg.sender, but this function can now be executed post-deploy only via proxy-admin-driven upgrade calls; in that path, msg.sender inside delegatecall is the ProxyAdmin contract. That means delayed initialization mints the premine to ProxyAdmin, and those tokens are effectively stuck because ProxyAdmin has no generic ERC20 transfer method.
Useful? React with 👍 / 👎.
