explorer's Issues

gas limit

how can i get more gas?

https://explorer.nebulas.io/#/tx/fbf222825c9b8ea0cb7224a8901af62d90ff2fb30037c7591dd9080bd954f1ad

Add option to view list of contracts deployed

Would be great to have a feature to browse/search deployed contracts on the Nebulas blockchain, similar to: https://etherscan.io/contractsVerified

Typos and color misconfiguration

There are a few typos scattered around the explorer, and NAS isn't always capitalized as I believe it should be.
Additionally, the green / red colors when the NAS price is up/down for the day is switched.

it is slow to synchronize block

we use a single thread to process grpc subscribe event, so sometimes it is slow to synchronize block which has too many transactions.

Smart Contract Address Loading Issue: the new feature view smart contract on contract address page fixed.

Hi,

In development circle, I found that the example page https://explorer.nebulas.io/#/address/n1gDfiiQLEBu95xDWHGxNi4qToyXjD2vE4D's View Smart Contract router-link is low speed than other and it need to load more than 2 seconds until the whole page loaded.

To demonstrate the problem, let's see the code:

135  <span v-if="contractHash">
136       <router-link class="btn btn-link" v-bind:to='fragApi + "/tx/"+contractHash'>View Smart Contract</router-link>
137  |</span>

305 urlChange() {
306               this.contractHash = ""

311 api.getTransactionByContract({ address: o.address.hash }, this.$route.params.api, (transaction) => {
312      var transaction = JSON.parse(transaction)
313      this.contractHash = transaction.result.hash
314  })

322  data() {
323      return {
324          contractHash: "",

I addressed this problem by adding contract data:
contract: null,
And pack tx result to contract data:
this.contract = transaction.result
The if condition:

<span v-if="obj.address.type">
      <router-link class="btn btn-link" v-bind:to='fragApi + "/tx/"+ contract.hash'>View Smart Contract</router-link>
|</span>

Lastly, removing the unnecessary contractHash, I've passed successfully on the above page.
This is the mainnet issue, please be aware.

un irreversible block can be reversible

when block is not irrenversible, it may be reversible and transactions resend to transaction pool. so when a block reaches an irreversible state, all of blocks which height less than irrenversible block and they are not irrenversible, should get data again through rpc interface.

未被确认的异常交易

这是什么情况，属于某种bug吗？

Front-end index page title & favicon

Currently the title on the main page on the explorer is set to explorer and no favicon is provided in the static folder.

build a docker file to run explorer project

wrong address

Sent purchased NAS tokens from Binance to nebulas address instead of into my nebulas wallet. How can I claim them?

[Bug] Search bar only searches on mainnet even when switched to testnet

Even though the explorer is pointed to the testnet, when searching with the search bar on the top right it searches the mainnet instead.

Search by tx hash does not work

Try searching any tx hash in the search box and no transaction is returned.
The search http request return 500.
But in RpcController's search method, it is querying the transaction too, so it should be able to support search by tx hash.

Weird timestamps in Testnet

Hello Guys,

im playing around on my first dApp in Testnet. I deployed the smart contract and was able to send in some data. But 2 of the transactions have wierd timestamps.

If you look at the smart contract addresse here: https://explorer.nebulas.io/#/testnet/address/n1wuEjThnWh6PDnP4o3dhsCXpT6hF3P9vVS

you can see that the TXs

https://explorer.nebulas.io/#/testnet/tx/81e646c0af35921f3722ae5466e367500db11ff789ef161e2545dd90fd7a7412
https://explorer.nebulas.io/#/testnet/tx/e00033a3ca41be75f74e3f51e1d1b0045392d5ac4d7895466e8c4e6a115cb780

are somehow off with their time stamp.

The first transaction on the SC was made manualle via the local webwallet to test. All the other transactions were made via the inferface.

The balance of account update strategy

Now, the balance is cached in database, it can be update only when some one view the page of address detail, this strategy is highly delayed, we need a more timely update strategy.

Subscribed events may be lost

Subscribed events can not be trusted, sometimes it may be lost event, so we should have a pull method to get the latest block.

CI(Continuous integration) task

When someone submitted the code was merged into the master branch, should be able to go automatically deployed to the server，so we need write a automatic deployment task deploy code

explore not showing transaction amount of NAS? at least today

transcation list of a address may should be ordered by nonce

for example:
https://explorer.nebulas.io/#/address/n1N1kWpZ1CC4HHFM4ZCe3xzgAFZAZNYhcvg

please watch the transactions with nonces from 3 to 8

No scroll bar to find in the explorer

This is my first time to enter the NAS explorer, but unfortunately I cannot find the scroll bar to continue to view the rest of the information in the bottom of the web page, I'm not sure whether it is the bug in some condition, hope developer could fix this issue

And this address has a lot of nas but currently its balance is hard to figure out how much nas

Can't find NAS account using Explorer

I created a new NAS wallet using the web wallet download. I can't find my address using the explorer.

I see two issues:

There is no search function to allow me to enter my address and search.
My only option is to click on an existing address and change the URL to use my public address instead. This isn't good usability. However, I get a page not found error.

I would expect that I could visit: https://explorer.nebulas.io/#/address/myaddress
But... This does not work. This gives me a 404 error. Do I need to make a deposit to the address before it will show as valid? This is not the behavior that I would expect.

block information

Search box related display problem

Add a expiry time for `pending tx`

The lifecycle of a tx is:
created -> pending -> packed in block or reject from LRU cache

So it's not easy to identify whether a pending tx is pending or not. So, I'd suggest we add expiry time in Explorer to auto cleanup expired pending tx.

The value of expiry could be 48h for production, 1h for development.

NAS market capitalization update information

we need a task to constantly update nas's market capitalization information

Multi-dimensional charts show nebulas information

At explorer version 1.0.0 (tag: explorer-tag-1.0.0), we only show the basic information of block、transaction and address。It is just a one-dimensional description of the nebula chain data information, we should fit the data from different dimensions, so we need a lot of different charts to show the nebula chain data

How to contribute to explorer?

I am running in local front-end environment and editing back-end data.
The result is not shown on expectation.

Directly linking to tx routes user to 404 page

Hey guys - looking to start contributing to this project. Yes, I believe....

Anyway, the block explorer will 404 if you try to visit a transaction ID directly, in a new tab.

Repro steps: right click this url and click 'open in new tab'

https://explorer.nebulas.io/#/tx/04f37719b8f00b70a0b20b4127770d113b8780772739b2617c031c21fd2198ff

that is the txID of the genesis transaction that has the manifesto. Seems like theres some routing issues going on. Side note - do you guys need help making a more "nebulas" 404 page? this one is very 90's

Thanks for the hard work
