# How to check the Lido DAO onchain vote #181

## What the vote is about

[The onchain vote #181](https://vote.lido.fi/vote/181) packs together execution of the three different motions:
- Tweaking ATC and PML quarterly Easy Track stables transfer limits PML: 6M ->4M stables / quarter & ATC 1.5M -> 7M stables/quarter ([snapshot](https://snapshot.org/#/lido-snapshot.eth/proposal/0x44bc7db53129ab4048c7f6f5cdc03407ec73444cbb5976c9579cb19bd3b57f7e))
- Tweaking and resetting Stonks stETH transfer limits 9k stETH -> 12k stETH / 6 months ([TMC proposal](https://research.lido.fi/t/tmc-4-increase-stonks-execution-limits/8616/2))
- Simply Staking Node Operator Reward Address change ([forum request](https://research.lido.fi/t/node-operator-registry-name-reward-address-change/4170/36?u=kadmil))

## How to Validate Proposals
Using the how-to, one can verify all addresses and details of the instruction. Let's check one address as an example to ensure it is not malicious.

Imagine the following situation: *the limits need to be changed for ET on ATC. The instruction states that increasing the limit from 1,5m to 7m USDC/USDT/DAI per quarter is necessary. In other words, to set 7'000'000 limit on ATC registry `0xe07305F43B11F230EaA951002F6a55a16419B707` for 3 months*

In this case, we need to verify the address `0xe07305F43B11F230EaA951002F6a55a16419B707`.

To do that, we go through several steps:
1. At first, we're going to work with [https://docs.lido.fi](https://docs.lido.fi/) to make sure that the contract belongs to Lido:
- In the search bar in the upper-right corner, paste the address and click on the result:
- Using Cmd + F (on Mac) or Control + F (on Windows), find the address on the page and check that it belongs to the registry:

2. Next, we want to make sure that the method mentioned in the instruction does what it says it does:
- Go to the contract page (press the button "**Contract**"):
- Press the “**Write contract**” button:
- Find the method mentioned in the instruction and click on its name:

3. We need to check the params:
- Ensure that the names of the params for the method setLimitParameters on https://etherscan.io and in the instruction match:

4. Now, let's verify the values of the params:
- Ensure that the values mentioned in the description and in the code match (all limits in this vote are multiplied by 10^18 to follow the requirements of the contract -- read about [decimals](https://etherscan.io/token/0x6b175474e89094c44da98b954eedeac495271d0f#readContract#F5) in DAI):

5. At last, it's necessary to verify that the description of the proposal on https://research.lido.fi (+ https://snapshot.org/#/lido-snapshot.eth if there's a snapshot) and in the instruction match. Don't forget to check the author of the proposal and comments (to ensure there are no objections):

We've verified one address, the params for its method, and the description of the proposal by using https://etherscan.io/, https://docs.lido.fi, https://snapshot.org/#/lido-snapshot.eth, and https://research.lido.fi/. By following these steps, you can verify the rest of the information provided in this instruction to ensure that it is not malicious.
