4. Open application

Deployed app : https://token-vesting-ui.netlify.com Or you can run in local

npm start

5. Deploy your own vesting contract

If you don't have a vesting contract to try this out, deploy your own easily:

i. Make sure you are connected to an ethereum node. You can use testrpc to simulate one:

npx testrpc

ii. Edit your vesting configuration

Edit the file migrations/2_deploy_contracts.js with the correct beneficiary, start date, duration and cliff. Revocable allow contract creator to withdraw the not yet released tokens.

iii. Deploy the contracts:

npx truffle migrate

You should get a TokenVesting address:

Compiling ./contracts/MyVesting.sol...
Compiling zeppelin-solidity/contracts/math/Math.sol...
[...]
Writing artifacts to ./build/contracts

To deploy on test network or mainnetwork, check the truffle.js file. You can either use a mnemonic that you put inside a .env file along with an infura API key You can also deploy to mainnet with a ledger device.

npx truffle migrate --network mainnet_ledger

6. Ready!

Go to http://localhost:3000/<token-vesting-address>/<erc20-token-address> and interact with the contract!

7. Interact with the contract

You must have Metamask open and configured in your browser to be able to interact with the contract.

  • As beneficiary: You can release your coin when it's time. Assure that the account selected in metamast is the beneficiary one, then release the token by accepting the transaction.

  • As contract owner: If contract is revocable, the contract owner can withdraw unreleased token. Also needs to select the owner account in metamask.

If you don't want to use metamask or this interface, you can use myetherwallet. The ABI is inside contract/build/TokenVesting.json file.
