How the Standard Vault works

• No lockup: You can request a withdrawal at any time

• Withdrawal waiting period: After requesting a withdrawal, a redemption waiting period of about 7–8 days may apply.
  After the waiting period, your principal + accumulated yield will be sent to your withdrawal address.

• Target yield (APR): Managed to target an annual fixed target yield (APR) of around 2.5%

• Yield updates: Automatically reflected inside the Vault (compounding) / updated once per week
  (Every Friday 01:00 UTC)

3. 3) Enter the amount and click the Withdraw button.

1. 4) To continue, click the “Sign” button.

2. 5) Review the signing details in your wallet, then authenticate with your fingerprint or PIN (password) to sign.

3. 6) Once signing is complete, “Withdrawal request succeed” will appear on the main screen, confirming your withdrawal request. You can check the withdrawn amount in your D’CENT Wallet XRP or XRPL trustline account.

4) Partnership termination after the bonus airdrop is completed

As of the point when all Launch Boost XRP bonus airdrops for Prime Boost Vault 1 and 2 are completed, the commercial partnership and related agreements between the two parties will end.
