There may be an issue with data retrieval from the API.

[tksarah]

Recently, I noticed a discrepancy between the information retrieved from the following API and the data displayed on Astar Portal.

It seems likely that Astar Portal has the correct information.

Could there be any issues with data retrieval from the API?

https://api.astar.network/api/v3/astar/dapps-staking/stakerslist/

For Example:

A clear example is that recently, the dApp "NFT Bridges" was listed.
However, I noticed that the amount staked in this dApp is not being accurately retrieved from the API.

From API
This dApp has been approved under the UCG program, and 25M has been staked.
Therefore, the API should be able to retrieve this information, but it seems that it's not being picked up correctly from API.

[
  {
    "amount": "1000000000000000000000",
    "stakerAddress": "bQb5W84HnCAE6V7YzazCXG1yf7gTBepT3v3vUkr7XL8ghPM",
    "stakerAddressEvm": "0x806eeb7c21494aa3839dbb549b6948e012b44c65"
  },
  {
    "amount": "1125000000000000000000",
    "stakerAddress": "ZUug9AtzRXCVhikp4X9n5ARmq3PcbcebHts8WHB1fdKJbV5",
    "stakerAddressEvm": null
  }
]

From Astar Portal

Hi @tksarah thank you for the report, let me check and circle back here

Hi @gtg7784,
How is this matter progressing? It seems that accurate information is still not being retrieved via the API.

As you may know, correct information was obtained by fetching data from 'Chain state' in Polkadot.js, specifically from PalletDappStakingContractStakeAmount.
I assume that Astar Portal is retrieving data directly from the chain, which is why it is displaying correctly. (Sorry, I'm not good at TypeScript, so I can't interpret it...)

Hi @tksarah I'm checking the issue right now, but we are also facing some performance issue of token api which related to the RPC connection. Will keep you updated and fix this issue as soon as possible, thank you for supporting and kind understanding.

[tksarah]

Thank you for sharing the progress! Understood!

Hi @tksarah , after checking the portal sources, as you said, I found that we are querying rpc using api.query.dappStaking.contractStake method with dapp id. In the API, the logic is different, will keep you for this updates, thank you :)

Hello @gtg7784,
Thank you for confirming the Astar Portal specifications. I'm glad to hear that everything is as expected!

Please continue checking the API, and I'll be waiting for further updates!

Hi @tksarah ! This token api is fetching data from our dappstacking indexer, and the issue was we are not implemented indexing dappstacking.stakemoved event. There is also another issue from subsuqid team that they are not supporting stakemoved, I requested support to Subsquid team. I will keep update you, thank you!

Hello @gtg7784
Thank you for the update! I understand, and I look forward to working with you further!

Is there any progress on this?
