This marks the bare minimum functionality for the ExoBridge contracts. There are three APIs:

• User: deposits and withdrawals
  

• Admin: deploy, add token associations, and update a few parameters
  

• Stakers: stake, destake, propose roots
  

The consensus mechanism around staking and proposing blocks makes this too dangerous for full release. This API will be the focus of future versions. User deposits and withdrawals are also quite expensive, so future versions will try to reduce this cost and consolidate withdrawal functions.
