- set claiming to be opened, to allow users to claim their points. The hacker could use this authority to prevent users claim their points and transfer funds.
- set the contract which will receive claimed funds. The hacker could use this authority to steal the claimed funds.

The contract is serving as the underlying entity to interact with one or more third party protocols. The scope of the audit treats third party entities as black boxes and assume their functional correctness. However, in the real world, third parties can be compromised and this may lead to lost or stolen assets. In addition, upgrades of third parties can possibly create severe impacts, such as increasing fees of third parties, migrating to new LP pools, etc.

    rETH = _rETH;
    wstETH = _wstEth;
    sfrxEth = _sfrxEth;

    rETHInstance = IERC20(_rETH);
    wstETHInstance = IERC20(_wstEth);
    sfrxEthInstance = IERC20(_sfrxEth);
```
- The contract `EarlyAdopterPool` interacts with third party contract with `IERC20` interface via `rETHInstance/wstETHInstance/sfrxEthInstance`.
