Understanding Balance Accrual in Locked Vaults

When you deposit assets into a Concrete vault, your balance starts accruing yield based on the vault's strategy. However, during the lock-up period, withdrawals are not available, and the final yield percentage will only be determined at the end of the vault cycle.

How Yield Works in Locked Vaults​

1. Your Balance Accrues Yield Continuously, But Final Rewards Are Confirmed at Unlock​

  • When you deposit into a vault, your Balance Accruing Yield will reflect the ongoing increase in value as APR and/or vault rewards are added over time.
  • Your displayed balance will increase as rewards are applied, but the final, total rewards can only be fully determined when the vault unlocks.

2. Withdrawals Are Not Available Until the Vault Unlocks​

  • Since vaults follow a fixed lock-up period, users cannot withdraw assets early.
  • Your assets remain in the vault, earning rewards until the end of the cycle.

3. The Total Yield is Calculated at Unlock​

  • Once the vault unlocks, the full earnings will be available for withdrawal.
  • Until then, your dashboard will display your current Balance Accruing Yield.

Scenario: User Deposits into a 90-Day Locked Vault​

  • A user deposits $1,000 into a Concrete vault that is locked for 90 days.
  • Concrete implements the vault strategy, generating yield through APR and/or vault rewards.

How the Balance Changes Over Time​

  1. Day 1

    • The user sees their Balance Accruing Yield as $1,000.
    • The vault strategy has started, but no rewards have been applied yet.

  2. Day 30

    • Concrete has accrued 3% APR and an additional $10 in vault rewards.
    • The user’s Balance Accruing Yield now shows ~$1,030, reflecting earned yield so far.
    • However, this is still subject to change as the vault continues earning over time.

  3. Day 60

    • More APR is added, and additional vault rewards accumulate.
    • The displayed balance might now be $1,060, but final calculations are still ongoing.

  4. Day 90 (Vault Unlocks)

    • The vault’s total rewards are finalized based on the full performance over the 90-day period.
    • The user can now withdraw their original deposit plus the earned yield.
    • If the vault achieved 6% APR and $50 in additional vault rewards, the final total would be $1,110.
