Get-method get_locker_data returns the smart contract parameters:
total_coins_locked - total amount of deposits from users in nanotons.
total_reward - total reward in nanotons.
deposits_end_time - unixtime, deposits and rewards are not accepted after this time.
vesting_start_time - unixtime, unlock of deposits starts after this time.
vesting_total_duration - total vesting duration in seconds (e.g. 31104000 for one year).
unlock_period - unlock period in seconds (e.g. 2592000 for once a month).
deposits_end_time must be less than vesting_start_time.
vesting_total_duration must be divisible by the unlock_period - mod(vesting_total_duration, unlock_period) == 0.
All time parameters must be greater than zero.
In order to make a deposit, you need to send at least 50 TON to the locker contract with a text comment "d" (lowercase letter).
Anyone can send.
A deposit minus 1 TON is credited (1 TON goes to network costs).
One user can send several times in this case the deposit is summed up.
⚠️ ATTENTION: Always send a message in BOUNCEABLE mode. Use-bflag if you using wallet-script.fif.
If you send less than 50 TON or message without valid text comment, the amount will bounce.
If send after deposits_end_time the amount will bounce.
In order to add reward, you need to send at least 50 TON to the locker contract with a text comment "r" (lowercase letter).
Anyone can send.
A reward minus 1 TON is credited (1 TON goes to network costs).
Rewards can be sent several times in this case the total reward is summed up.
⚠️ ATTENTION: Always send a message in BOUNCEABLE mode. Use-bflag if you using wallet-script.fif.
If you send less than 50 TON or message without valid text comment, the amount will bounce.
If send after deposits_end_time the amount will bounce.
The reward is accrued according to the amount of the user's deposit and the total amount of deposits.
If there are two users with a deposit of 100 TON and 1000 TON and a total reward of 500 TON, then after a complete unlock:
first user will receive = 100 + (100 * 500 / 1100) = 145 TON.
the second user will receive = 1000 + (1000 * 500 / 1100) = 1454 TON.
Until vesting_start_time deposits are blocked.
After vesting_start_time deposits start unlocking every unlock_period.
Full unlock date is vesting_start_time + vesting_total_duration.
In order to withdraw the current unlocked funds, you need to send 1 TON to the locker contract with a text comment "w" (lowercase letter) from the wallet from which the deposit was sent.
The amount unlocked at the moment will be sent to the user's wallet.
If the total amount of the user is 1000 TON (deposit + his part of the reward), and vesting_total_duration = 12 months, and unlock_period = 1 month, then
by sending a withdrawal request in the third month, the user will receive 1000 * 3 / 12 = 250 TON.
Then, by sending a withdrawal request in the 12th month, the user will receive 1000 - 250 = 750 TON.
Locker system consists of two contracts: Locker itself and locker-bill.
Locker stores all locked funds and reward. It's behavior is determined by four immutable parameters: deposits_end_time, vesting_start_time, vesting_total_duration and unlock_period set during deployment.
Locker-bill is used to store data about locks in sharding friendly way.
When receiving a deposit, Locker creates auxiliary Locker-bill contract that store the user's address and his total deposit.
The user does not need to interact with auxiliary Locker-bill smart contracts.
