This is meant to generalize the
hubPool
variable in all spoke pools. ThehubPool
variable is only used in_bridgeTokensToHubPool
, where it is set as the recipient. For spoke pools deployed on L3s, or for spoke pools which may not want to withdraw token to the hub pool (e.g. theBlast_SpokePool
), thehubPool
variable is either a misnomer or unused. This changes the variable to be calledwithdrawalRecipient
to better reflect the purpose of thehubPool
variable.
