Welcome to the Vesting Scheduler smart contract developer quickstart. Here, you’ll learn how to schedule the vesting with Superfluid streams using the Vesting Scheduler. This guide assumes a knowledge of basic Solidity (such as the ERC20 standard, block.timestamp, etc.) and performing web3 calls. Let’s get started 🚀

Setting Up Vesting

1. Set the correct permissions

The Vesting Scheduler contract never holds any of your tokens to vest, it simply uses permissions to move them for you from your wallet (or Safe). Here are the permissions you need to set up:

1. Flow Operator Permissions

Give the Vesting Scheduler contract maximum permissions over creating streams on your behalf with the authorizeFlowOperatorWithFullControl function.

/**
 * @dev msgSender from `ctx` grants `flowOperator` create/update/delete permissions with flowRateAllowance as type(int96).max
 * @param token Super token address
 * @param flowOperator The permission grantee address
 * @param ctx Context bytes (see ISuperfluid.sol for Context struct)
 */
function authorizeFlowOperatorWithFullControl(
    ISuperfluidToken token,
    address flowOperator,
    bytes calldata ctx
)
		external virtual
		returns(bytes memory newCtx);
