Token Timelock

About

Token timelock smart contract. Use /contracts/production/TimelockERC20.sol for lock ERC20 tokens.

TimelockERC20

This contract allows you to send some tokens, but receiver can't take them until the set date.

SafeERC20Timelock

This contract allows you to get accidentally sent balance back (by contacting with contract owner)

Usage

Sender should approve to send balance in ERC20 token using function approve(address _spender, uint _value)

• _spender is your contract address
• _value is number of tokens to send

Then sender can send tokens to contract function accept(address _for, uint _timestamp, uint _tvalue)

• _for is recipient address.
• _timestamp is date until recipient can't get his balance.
• _tvalue is number of tokens to send

Then recipient should call release to get his balance using: function release(uint[] _timestamp, uint[] _value) Should be in order timestamp[n] -> value[n]

Contract owner can call: function saveLockedERC20Tokens(address _token, address _to, uint _amount) To restore accidentally sent tokens back to sender.
