Yearn Vesting Escrow

A modified version of Curve Vesting Escrow contracts with added functionality:

• An escrow can have a start_date in the past.
• The first unlock can be delayed using cliff_length.
• An ability to claim partial amounts or use a different beneficiary account.
• An ability to terminate an escrow and clawback all the unvested tokens using rug_pull. The recipient is still entitled to the vested portion.
• Factory admin controls removed, anyone can deploy escrows, funds are pulled instead of pushed.
• Factory emits an event which allows finding all the escrows deployed from it.

Contracts

• VestingEscrowFactory: Factory to deploy many simplified vesting contracts
• VestingEscrowSimple: Simplified vesting contract that holds tokens for a single beneficiary

Usage

$ brownie console --network mainnet

factory.deploy_vesting_contract(token, recipient, amount, vesting_duration, vesting_start, cliff_length)
