Staking Workflow

How to stake via a UI?	View available options below.
How to integrate staking into a wallet/custodian solution?	In order to stake BTC on Babylon you need to initiate a staking transaction on the Bitcoin blockchain. The components of these transactions are: 1. The Finality Provider information: You will specify which Finality Provider (Validator) you are delegation your staked assets to. 2. A Timelock Transaction: You lock your coins for a specific amount of time. After that amount of time has passed, the coins can be instantly redeemed. 3. Slashing transaction: You pre-sign a transaction that will slash some of your staked coins if an only if your Finality Provider double-signs when securing consumer chains. Please see the wallet integration guide here.
Can I keep staking/unstaking from/to the same wallet?	You can not add to your existing stake position. If you want to stake more, it will have to be through a different position.
Can I select how much of my wallet balance I want to stake?	Yes.
Can I unstake part of the staked balance?	That functionality is not allowed by the protocol for now.
When can I withdraw my staked BTC?	Either - After redemption, at the end of the timelock period you have set when you initiated the staking action. Funds will instantly be withdrawn. - After you initiate an "unbonding" transaction, which will withdraw your BTC after 7 days.
