DelayVault

Smart contract that pre-locks tokens indefinitely by creating Vault. When the Vault is closed by withdrawing tokens, a Pool is created for the specified period using a Locked-Deal contract.

Create new Vault

Problem:

To participate in IDO, need to lock tokens. There are usually pre-agreed conditions for participation, such as a minimum number of tokens and a locking time. After the lock time expires, the user may forget or physically be unable to re-lock the tokens for a longer period of time due to the restrictions of the Locked-Pools contract.

Solution:

Create a Vault that doesn't start the lock time before the start of the withdrawal.

https://github.com/The-Poolz/DelayVault/blob/a76a1825297a9126120ba47a83305f0a1287a9c9/contracts/DelayVault.sol#L12-L18

• _token - the address of the token that will be locked in vault.
• _amount - the number of tokens that will be in the vault, if there are already tokens in the vault, they will be summed up.
• _startDelay - the period of time after which the pool will start when withdraw the tokens from the vault.
• _cliffDelay - time parameter that sets cliff for creating the pool.
• _finishDelay - the time for which the tokens will be locked in the pool.

Start Lock Period

Creates a new pool of tokens for a specified period or, if there is no Locked Deal address, sends tokens to the owner. https://github.com/The-Poolz/DelayVault/blob/a76a1825297a9126120ba47a83305f0a1287a9c9/contracts/DelayVault.sol#L61

• _token - which token do you want to withdraw.

Admin settings

Set Locked Deal address

setLockedDealAddress allows the admin to set the address of the LockedDealV2 contract. Without a Locked-Deal address, the user will immediately receive their tokens upon withdrawal! https://github.com/The-Poolz/DelayVault/blob/35eba8d1dc7ba9db7edbf39ad73441e05c58e78d/contracts/DelayManageable.sol#L12

• _lockedDealAddress - the new address of the Locked-Pools. Its default address is zero.

Setting Minimum Delays

The administrator can set the minimum delay time and the minimum number of blocked tokens. Each token limit can have its own minimum block time. When setting amounts, they should be sorted from smallest to largest. https://github.com/The-Poolz/DelayVault/blob/35eba8d1dc7ba9db7edbf39ad73441e05c58e78d/contracts/DelayManageable.sol#L20-L26 If restrictions are set, the user will not be able to specify a lower value. The admin can specify his own minimum block time for a certain number of tokens.

• _token - the address of the token to which the blocking rules will apply.
• _amounts - array of quantitative limits of tokens.
• _startDelays - array of delay start limits.
• _cliffDelays - array of output time limits in the pool.
• _finishDelays - array of pool end limits.
