Delegation is one of the blockchain functions that makes tokens locked for a certain period of time (until the moment of unbond tokens from staking), and also these tokens are not transferred to a third party. So when you send tokens to staking, you are still their full owner.
However, the Minter Hub network lacks a user-friendly and familiar user interface, and it would be quite difficult for an ordinary user to make any transactions. To facilitate delegation for regular users, Interstake One has a custodial delegation feature. You send a HUB to the special address in the Minter network, in return you receive a LIQUIDHUB receipt-token (Liquid Staking Derivative), confirming the ownership of HUB tokens and guaranteeing the possibility to withdraw coins and receive your tokens back after a certain period of unbonding — 21 days. Thus, Minter Hub has 2 delegation options: non-custodial (complex) — without transferring tokens to third parties and custodial (simple) — with transferring tokens to a validator.
