Moved parts of the code that are common and will be used for ETH bonding from KeepBonding to AbstractBonding contract. Only withdraw related functions remain in KeepBonding as they require different roles handling.
As TokenStaking contract has been refactored in keep-network/keep-core#1867 we can use Authorizations and StakeDelegatable contracts calls as these contracts define the functions we use in bonding. In this commit we use separately Authorizations and StakeDelegatable instead of TokenStaking to be more flexible and able to use common code from AbstractBonding for both KEEP token and ETH bonding.

We added abstract functions for the calls we expect to make to staking contract. For KEEP token staking we expect calls to TokenStaking and for ETH staking calls to dedicated staking contract. We no longer need to pass two addresses: Authorizations and StakeDelegatable contract which seemed to be confusing.
Updated unit tests stubs to handle functions added to AbstractBonding contract that should implement calls to staking contract holding informations about delgation.

Solium complains about indentation problems but indentation is fine. Indentation is verified and fixed by prettier so we can ignore indentation cheks from oslium.

We will need to get to the functions from keep facotry and keeps.

There was a problem hiding this comment.
We usually do public* in other tests, can we rename it to publicWithdrawBond to keep it consistent?

This PR is preparation for ETH only staking. We extracted some common parts of
KeepBondingcontract that almost entirely can be used for ETH bonding and placed them inAbstractBonding. The only difference, for now, iswithdrawthat in case of KEEP token staking has to support grantee roles check. This is an abstract function inAbstractBondingimplemented byKeepBonding.Refs: #271
