# Yearn Vesting Escrow
A modified version of [Curve Vesting Escrow](https://github.com/curvefi/curve-dao-contracts) 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 `open_claim` and let anyone to claim for beneficiary recipient.
- An ability to terminate an escrow and choose beneficiary for the unvested tokens using `revoke`. The recipient is still entitled to the vested portion.
- An ability to use ERC20 non-compliant `token`, e.g. USDT.
- An ability to `support_vyper` at escrow creation.
- 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`](contracts/VestingEscrowFactory.vy): Factory to deploy many simplified vesting contracts
- [`VestingEscrowSimple`](contracts/VestingEscrowSimple.vy): Simplified vesting contract that holds tokens for a single beneficiary
## Usage
```python
$ ape console --network mainnet
funder = accounts.load(name)
factory = project.VestingEscrowFactory.at('0x200C92Dd85730872Ab6A1e7d5E40A067066257cF')
factory.deploy_vesting_contract(token, recipient, amount, vesting_duration, vesting_start, cliff_length, open_claim, support_vyper, owner, sender=funder)
```
