Skip to main content Alpha Vault implements a sophisticated vesting and token distribution mechanism with support for both pro-rata and first-come-first-served (FCFS) allocation modes.
Linear Vesting Formula The core vesting mechanism follows a linear time-based release schedule:
claimable_tokens = elapsed_time × total_bought_tokens total_vesting_duration \text{claimable\_tokens} = \frac{\text{elapsed\_time} \times \text{total\_bought\_tokens}}{\text{total\_vesting\_duration}}
claimable_tokens = total_vesting_duration elapsed_time × total_bought_tokens Where:
elapsed_time = time since vesting starttotal_bought_tokens = total tokens purchased by all userstotal_vesting_duration = total duration of vesting period
Individual Token Claim Formula user_claimable = total_claimable × user_deposit total_vault_deposit − already_claimed \text{user\_claimable} = \frac{\text{total\_claimable} \times \text{user\_deposit}}{\text{total\_vault\_deposit}} - \text{already\_claimed}
user_claimable = total_vault_deposit total_claimable × user_deposit − already_claimed Where:
total_claimable = total tokens available for claiming at current timeuser_deposit = individual user’s deposit amounttotal_vault_deposit = sum of all user deposits in the vaultalready_claimed = tokens already claimed by the user
Refund Calculation Formulas Base Refund Calculation refund = unswapped_amount × user_deposit total_deposit \text{refund} = \frac{\text{unswapped\_amount} \times \text{user\_deposit}}{\text{total\_deposit}}
refund = total_deposit unswapped_amount × user_deposit Deposit Overflow Refund (Pro-rata Vaults) overflow_refund = excess_deposit × user_deposit total_deposit \text{overflow\_refund} = \frac{\text{excess\_deposit} \times \text{user\_deposit}}{\text{total\_deposit}}
overflow_refund = total_deposit excess_deposit × user_deposit Where:
excess_deposit = total deposits exceeding the maximum buying capunswapped_amount = tokens that weren’t successfully swapped
Swappable Amount Calculation Pro-rata Mode max_swappable = min ( total_deposit , max_buying_cap ) \text{max\_swappable} = \min(\text{total\_deposit}, \text{max\_buying\_cap})
max_swappable = min ( total_deposit , max_buying_cap ) FCFS Mode max_swappable = total_deposit \text{max\_swappable} = \text{total\_deposit}
max_swappable = total_deposit Where:
max_buying_cap = maximum tokens that can be purchased (for pro-rata mode only)total_deposit = sum of all user deposits
Vault Mode Specifications Pro-rata Mode
No maximum buying cap restriction
Distributes tokens proportionally among all participants
Provides refunds for excess deposits
Suitable for unlimited token sales
FCFS Mode
Enforces maximum buying cap
Tokens distributed on first-come-first-served basis
No overflow refunds (all deposits are valid)
Suitable for fair distribution with limited token supply
