LEV Vesting
Vesting contract for the $LEV token
Vesting Stats
75% of team tokens vested for 12 months, released every month
Date Time Contract
The contract uses a newer version of BokkyPooBahsDateTimeLibrary you will need to use the one deployed to mainnet or deploy it manually.
Gas Costs
The following values are logged from unit tests which use go-ethereum simulated backend
| Action | Cost |
|---|---|
| Date Time deployment | 1090857 |
| Vesting deployment | 492694 |
| Vest preparation | 455530 |
| Vest release | 77157 |
Development
Dependencies
- Linux 64-bit OS
- Go 1.15
- Make
Testing
Testing of the vesting contract is done using the go-ethereum simulated backend, and testing of the smart contract via autogenerated contract bindings in the Golang language. For more information about go-etherum bindings see github.
Compilation
make compile- Compiles the Leverage token (note this is just used for testing)
- Compiles DateTime contracts
- Compiles vesting contract
- Generates JSON ABI files for all contracts in
bin
Golang Bindings Update
Updates the golang code bindings for the smart contracts
make abigen
Flattening
Flattens the Vesting contract into a single file, suitable for etherscan verification, usage with any solidity development environment, etc...
make flatten
All Of The Above
make all
Deployment
Take flattened/Vesting_Flattened.sol and use whatever preferred deployment system or development environment (truffle, hardhat, etc..). It should be compiled using Solidity 0.7.3, however you can manually adjust the compiler versiont to 0.7.x as desired.
The Vesting contract requires three arguments during deployment, and they are:
- The address of the LEV token contract
- The address of the BokkyPooBahsDateTimeLibrary contract version
v1.00 - The address of the owner which will be used to provision the contract After deployment you must approve the Vesting contract to spend funds on behalf of the
After the contract is deployed the prepare function must be called by the contract owner. It takes two arguments
- The amount of tokens (denominated in wei) to vest
- The address of the wallet that will receive the tokens (this should be the team wallet)
Once the prepare transaction is mined, every month following from the timestamp of the block it was included you may call the release function to withdraw the alloted amount from the Vesting contract. The tokens will be deposited into the receiver address when invoking the prepare function.
