Normal unstaking will adhere to the Polkadot unbounding period ~28 days. Homa protocol provides a fast redeem function for users to receive DOT/KSM liquidity faster than the normal unbounding period upon unstaking. This function will match fast redeem requests with queued staking as staked assets will be batched before being sent to Relay Chain via XCM for staking.
A fee is charged (currently 1% on Acala and Karura) for fast redeem. The fee received is shared among LDOT holders.
Application developers can use fast redeem in combination with Acala Swap to provide better and more instant liquidity for users. As an example see Acala DApp.
