Uniswap V2 INIT_CODE_HASH

gistfile1.txt

The problem is that you first need to compile the `uniswap-v2-core` contracts

Next, you need to get `INIT_CODE_HASH` from the bytecode of the `UniswapV2Pair.sol`

```js
// file ./get-init-code-hash.js
const UniswapV2Pair = artifacts.require('UniswapV2Pair.sol');
module.exports = async (callback) => {
  console.log(
    'UniswapV2Pair bytecode hash (Look for INIT_CODE_HASH):\n%s',
    (web3.utils.keccak256(UniswapV2Pair.bytecode)).substring(2)
  );
  callback();
}
```

Run it code
```bash
truffle exec ./get-init-code-hash.js
```

Next you need
1) Replace it in Line # 24 for `uniswap-v2-periphery/contracts/libraries/UniswapV2Library.sol`.
2) Replace it in `INIT_CODE_HASH` for` uniswap-sdk/src/constants.ts`.

_When replacing the code, you need to pay attention to the places where the prefix `0x` is found, you need to save it and replace what follows it._

Next you need
1) compile the `uniswap-v2-periphery` code

Next you need
1) deploy `UniswapV2Factory.sol` and `UniswapV2Router02.sol`
2) replace the corresponding addresses
