# v4 Referral hook

### **Hook for taking referral fees if provided a referral code🦄**

Built for the ethOnline Hackathon

---

### Local Development (Anvil)

_requires [foundry](https://book.getfoundry.sh)_

```

forge install

forge test

```

Because v4 exceeds the bytecode limit of Ethereum and it's _business licensed_, we can only deploy & test hooks on [anvil](https://book.getfoundry.sh/anvil/).

```bash

# start anvil, with a larger code limit

anvil --code-size-limit 30000

# in a new terminal

forge script script/Counter.s.sol \

    --rpc-url http://localhost:8545 \

    --private-key 0xac0974bec39a17e36ba4a6b4d238ff944bacb478cbed5efcae784d7bf4f2ff80 \

    --code-size-limit 30000 \

    --broadcast

```
