# eth2-deposit-contract

This is a just for fun port of the [Vyper Eth 2.0 deposit contract](https://github.com/ethereum/eth2.0-specs/blob/dev/deposit_contract/contracts/validator_registration.vy) to Solidity.

The motivation is to run the SMTChecker and the new Yul IR generator option (`--ir`) in the compiler.

**THIS IS NOT THE OFFICIAL DEPOSIT CONTRACT. NOT SUITABLE FOR ANY USE**

## Using this with the tests

1. Create the `deposit_contract.json` with running `make` (this requires `solc` to be in the path)
2. Download [eth2.0-specs](https://github.com/ethereum/eth2.0-specs)
3. Replace `eth2.0-specs/deposit_contract/contracts/validator_registration.json` with `deposit_contract.json`
4. In the `eth2.0-specs` directory run `make install_deposit_contract_tester` to install the tools needed (make sure to have Python 3.7 and pip installed)
5. Finally in the `eth2.0-specs` directory run `make test_deposit_contract` to execute the tests

The Makefile currently compiles the code without optimisations. To enable optimisations add `--optimize` to the `solc` line.
