Configuration

How to config?

Optionally, we use a configuration file under ~/.uxuyindexer/config.json on Linux or BSD, ~/Library/Application Support/uxuyindexer/config.json in Mac OS or $LOCALAPPDATA/uxuyindexer/config.json in Windows.

You can set the config by self when you start it in command line too.

The following is the config.json example.

from_block

It is very important when you want to index the data from blockchain, firstly you need to set a start time, here we use block height, I will give a example how to get the data.

You will know some ticks from your friends, community or others, now get the deployed hash from your information source, then go to the blockchain scan, such as

C Chain | Avalanche Blockchain Explorer | AVAX Explorer | AVASCANAvascanExplorer

You can use snowtrace to get the avas deploy info by the hash .

Block 31918263 -- This is the block height, you can use this in your config.
