# 31.05.22 How to check the vote for Merge-ready protocol upgrade (round 2)
The vote [#130](https://mainnet.lido.fi/#/lido-dao/0x2e59a20f205bb85a89c53f1936454680651e618e/vote/130/) has the number of actions without descriptions. There is a list of things that are going to be performed:
1. Create role RESUME_ROLE and grant to Voting
2. Create role STAKING_PAUSE_ROLE and grant to Voting
3. Create role SET_EL_REWARDS_WITHDRAWAL_LIMIT_ROLE and grant to Voting
4. Set Execution Layer rewards withdrawal limit to 2BP
5. Wrap stETH burner into the composite receiver
6. Attach composite receiver to lido oracle as beacon report callback
7. Revoke 'BURN_ROLE' permissions from Voting
8. Grant 'BURN_ROLE' constrained permissions to stETH burner
9. Create role MANAGE_PROTOCOL_CONTRACTS_ROLE and grant to Voting
10. Revoke SET_TREASURY from Voting
11. Revoke SET_INSURANCE_FUND from Voting
12. Revoke SET_ORACLE from Voting
To get the data in the voting script in readable format please refer to our how-to on checking Aragon votes: [https://docs.lido.fi/guides/checking-aragon-vote/](https://docs.lido.fi/guides/checking-aragon-vote/)
Or use our new UI for Aragon votings: https://vote.lido.fi/vote/130
After parsing, you will get the list of elements. And here are explanations and all links to [etherscan.io](http://etherscan.io/) for verification:

The parameter `_params` is needed to check that the address can burn only its own tokens.
For `_params` we use a string that is formed as concatenation of three params:

const argId = '0x00' // arg 0
const op = '01' // operation eq (Op.Eq == 1)
const value = padWithoutPrefix(addr, 240 / 8) // pad 160bit -> 240bit, remove '0x'
