Step 3 - Getting Details
Step 3 - Getting Details
Let’s dig deeper. Let’s query specific addresses. In other words, snoop.
Note: chances are very high that if you’re not running your own node, you will get rate limted with these commands.
Do this:
chifra names GitCoin:Grants
This command shows about 1,900 GitCoin grants from past rounds. Add a selector to the command:
chifra names GitCoin:Grants -s 291 | tee grants.txt # `291` is random. It just picks address that have 291 in them.
The chifra names tool allows you to keep track of the addresses you’re interested in. Adding the -s option shows only the addresses and selects a subset of the addresses. The tee command saves the output to a file.
Getting Balances
Now we can use this list of addresses to query the state of each of the addresses. Let’s get the balance of each of the addresses. Note how slow this is (TrueBlocks is a work in progress).
chifra state --no_header --ether --chain mainnet --file grants.txt
A bit slow, but this is the current ether balance of each of the grant receipients. I don’t know about you, all other things equal, I’d give to a project with a smaller balance than an larger one. Even if only because they’re smart enough to drain thier wallet.
Notice four other things with this command:
- The
--no_headeroption removes the header from the output. This is useful when you’re piping the output into another command. - The
--etheroption reports the number in ether. This option is available for tools when it makes sense. - The
--chain mainnetoption tells the tool to use the mainnet. If you don’t specify a chain, the tool will use the default chain, which is a configuration item. - The
--fileoption tells the tool to read the list of addresses from the filegrants.txt. This is a convenience option. You could have just as easily piped the output of thechifra namescommand into thechifra statecommand.
Getting Token Balances
We leave this part of the tutorial as an excercise. Run chifra tokens. Read the help text. Figure out how to get token balances for each of the grant receipients for any token, but here’s a hint:
The holdings as the latest block for each of the grants receipients for the DAI stable coin:
chifra names dai stable 0x6 -s | chifra tokens --no_header --chain mainnet 0x6b175474e89094c44da98b954eedeac495271d0f --file grants.txt --cache
The holdings each week for each of the grants receipients for the DAI stable coin:
chifra names dai stable 0x6 -s | chifra tokens --no_header --chain mainnet 0x6b175474e89094c44da98b954eedeac495271d0f --file grants.txt --cache 14000000-15000000:weekly
Don’t forget you can do a server version of this as well:
curl "http://localhost:8081/tokens?addrs=0x6b175474e89094c44da98b954eedeac495271d0f&no_header&chain=mainnet&file=grants.txt&cache&blocks=14000000-15000000:weekly"
curl "http://localhost:8081/tokens?addrs=0x6b175474e89094c44da98b954eedeac495271d0f&chain=mainnet&cache&blocks=10000000-17000000:daily&fmt=txt"
