Currently network wide stats are collected once every hour. It has been requested to increase to 4 times per hour.

Transferring verified contract data from the old to the new database

Currently explorer stats stores and returns only aggregated statistic for all chains. Need also to store and return data by chains

We need to run main functions of explorer admin in separate threads to do not block each other:

• Blockexplorer checker
• Stats collector
• Gas price updater

@DmytroNazarenko please add more info

• set up Releases workflows in skale-explorer repo

Describe the bug
Skale-explorer works with low downtime (>98% of uptime) but uses too many resources of the instance. Chains are without any load, so under load blockscout are going to crash or stuck with the lack of resources.

Preconditions
Active 8 chains without load
Active Skale-Proxy as the endpoint

To Reproduce

1. Connect to the instance where the skale-explorer is.
2. Check resource usage in any convenient tool

Expected behavior
Total RSS and CPU usage should use 50% of total resources (400% of 800% CPU and 16GB of 32GB RSS )

Actual state:
Skale-explorer usues almost 100% of allocated resources

Describe the bug
If there are two wallets are active in the browser - Coinbase and Metamask - while choosing Metamask wallet to connect, Coinbase popup window is displayed.

To Reproduce
Steps to reproduce the behavior:

1. Go to to any contract and choose "Write contract"
2. Click on "Connect wallet" and choose Metamask
3. See Coinbase popup window

Expected behavior
Metamask popup window is displayed with offer to connect wallet

Screenshots

Currently, block explorers operate almost at maximum capacity.

We need to be able to:

• Have easy to use guides to set up dedicated block explorers for specific dApps
• Make dedicated explorers has the same functionality as main explorer-admin

Dev implementing stats api has asked for this to be added to remove CORS Header error

Tried to download csv file with txs for a contract on a Skale chain but everytime it returns nothing
Will send all information about chain

Description
At the bottom of a explorer page a button Add {network} does not work.

To Reproduce

1. Open explorer (for example https://staging-perfect-parallel-gacrux.explorer.staging-v3.skalenodes.com)
2. Scroll down
3. Press Add staging-perfect-parallel-gacrux
4. Shed a tear

Expected behavior
The network is added to metamast

Need to enable internal transactions in Blockscout and fetch info from trace log by using archive node with tracing

Migrate to new Blockscout UI https://base.blockscout.com/

Currently our stats collection periodically fails with errors:

Query failed: could not resize shared memory segment "/PostgreSQL.1166100790" to 4194304 bytes: No space left on device

Until we do not reconfigure blockscouts infrastructure and architecture to customize space for Postgres DB, we need to cache previous succeed results to avoid zeros for failed chains in the stats

OKR: Q2 2023

Currently block explorers are stucking and failing under high load. We need to increase blockexplorer uptime to 98%

TODO: @DmytroNazarenko add more info

Need to add unit tests and tests that emulate work of explorer

If you deploy a contract from a contract factory it shows as EOA
