## Short summary 

In preparation for the upcoming release – and subsequent distribution – of the Polkadex Crowdloan PDEX rewards, the Polkadex core contributors have compiled on-chain (publicly available) contribution data obtained via explorers and off-chain contribution lists provided by DApp contribution partners, Equilibrium, Bifrost, and Parallel Finance. 

Thanks to this, each crowdloan contributor will be able to claim their rewards in the same way, no matter the method they used when originally contributing to the crowdloan, and without having to go through a third party. Essentially, we’ve removed the need for any manual distribution of crowdloan rewards through centralised agents. 

For the purpose of transparency and to further corroborate the list of eligible addresses, we wanted to share the total on-chain contribution list along with the address lists we received from our contribution partners:

[Bifrost contributors](https://docs.google.com/spreadsheets/d/1v0YjjSA9E2rsmvgiV_bpbWkiTf3Bz8ngTMz7gxfPhn0/edit?usp=share_link)

[Parallel Finance contributors](https://docs.google.com/spreadsheets/d/1wyNi6PbEjJ8j8hpUdjWdaF40Hqkaw8GwdVoFOFuMcS0/edit?usp=share_link)


We ask that DOT contributors take a look at the data, and if you find any discrepancy, we ask that you use the comments section of this discussion thread to let the Polkadex core contributors  and fellow community members know. Any potential discrepancy with a partner platform’s contributor list should be escalated with the respective platform, as they hold responsibility for their address list. Moreover, Polkadex core developers hold no responsibility for the above lists as we have simply integrated them into our Crowdloan Rewards claiming interface for the convenience of Polkadex Crowdloan contributors. 

## Known Discrepancy

You might notice that for Parallel Finance, the total DOT shown on their sheet and the amount of DOT locked towards the crowdloan from their account has a mismatch of 198 DOTs. This is because block # 9835496 events did not appear in the Subscan index for the Polkadex Crowdloan 2040. This discrepancy is explained – with links to the relevant data – as follows: 

1. [Subscan shows a total contribution from Parallel Finance of 505,654.58 DOT.](https://polkadot.subscan.io/account/13wNbioJt44NKrcQ5ZUrshJqP7TKzQbzZt5nhkeL4joa3PAX?tab=contribution)

2. [The list shared by Parallel Finance shows a total contribution of 505,852.58 DOT.](https://docs.google.com/spreadsheets/d/1wyNi6PbEjJ8j8hpUdjWdaF40Hqkaw8GwdVoFOFuMcS0/edit?usp=share_link)

3. Difference: 505,852.58 - 505,654.58 = 198 DOT

4. [194TkkmjuiNFHXFLkxTcTWfRpwgXZevtSFmezhFWhuBHqsH transferred 198 DOT to Parallel Finance.](https://polkadot.subscan.io/extrinsic/9835482-2) 

5. [Parallel Finance forwarded 198 DOT to the Polkadex Crowdloan.](https://polkadot.subscan.io/extrinsic/9835496-3?event=9835496-26) 

6. [Subscan List of Total Contributions.](https://polkadot.subscan.io/crowdloan_contribute/?fund_id=2040-36) 

7. [Here, you can see that the specific block event is missing from the Subscan list during that time period. ](https://polkadot.subscan.io/crowdloan_contribute/?fund_id=2040-36&page=81)

As a result of the above and to err on the side of caution, we have included this account with 198 DOT in the final rewards list.

## Centralized exchange contributors

If you contributed to the Polkadex Crowdloan via a centralized exchange, please note that the above is not applicable to you, as the exchange will claim the rewards on your behalf before distributing them to your account on the exchange. Please contact your relevant exchange for more information on the timelines and processes for receiving your rewards. 
 
## Direct contributors

If you contributed directly on-chain from your Substrate-based wallet or via the Polkadot.js apps interface, you will see your address in the ‘Total contributors’ list and you will be able to claim your rewards directly from the Polkadex claiming interface or Polkadot.js. 

## Distribution logistics 

Once the community has had a chance to go through the contributor lists above, the Polkadex core contributors will submit an on-chain governance democracy proposal to release the rewards from the Polkadex Treasury to the Crowdloan Rewards pallet. Once the proposal is approved by public referendum, the Treasury will transfer the funds to the Rewards pallet. This will take place no earlier than June 23rd 2023, 4 days after the estimated start of voting on June 19th. This in itself is dependent on the network’s adoption of v5.0.0: the new binary to be released on Wednesday June 7th 2023 and the subsequent runtime upgrade estimated for June 19th.
