This is a Lambdanistan project for fun of programming.

About etcql etcql is a tool that allows you to directly query account states (including the balance, nonce, code, code hashes, storage root, etc.) of the Ethereum blockchain using GraphQL, a querying language that allows clients to ask for exactly what they need. See below for an example of what this can do. The service uses a pay-what-you-want subscription scheme. You can use this service for free, and I would also appreciate it if you can buy me some beers, or make some donations so I can upgrade my server. The database is usually updated once per day. Currently it is only supporting the Classic blockchain. Ethereum blockchain might be added if there’s enough interest.

Example: Find All Parity Multisig Wallet Addresses The Parity Multisig Hack does not affect Ethereum Classic blockchain because Parity deploys a different contract on ETC network. So the query below is safe to run. etcql allows you to query via an account’s nonce , balance , codehash , code and storageroot . All Parity multisig wallets on ETC network has codehash of 0xa4b67e93913637de643e2763b797cf84e890e3a46a5c70ec73c00b45949287f0 So you can use the GraphQL interface and run the query below: { accounts(codehash: "0xa4b67e93913637de643e2763b797cf84e890e3a46a5c70ec73c00b45949287f0") { address } } It will output all addresses with this codehash . Note that there are not a lot of multisig wallets in ETC network!

Get Started Go to https://etcql.that.world/register and you will get a pair of publicToken and privateToken . Keep your privateToken safe. Next, create a custom transaction on the ETC network. You will need to set the recipient to 0x00bBc4F428008CFa801BbB112717E3b110a7A1B5 , and set the transaction data to your publicToken . (For Parity, that means to tick “advanced sending options” and paste your publicToken in the next page.) Just set the transaction value to 0 if you wish to use this service for free. The subscription will be valid for one day. If you want to buy me a beer, however, you’ll get longer subscription validity. A transaction of 0.3 ETC and over would give you a subscription of one week.

A transaction of 1 ETC and over would give you a subscription of one month. Just re-send a new transaction with the transaction data of the same publicToken when you old subscription expires. To use the GraphQL interface, you normally interact with the https://etcql.that.world/graphql endpoint. It would ask you username and password in HTTP BasicAuth. Your username is the transaction hash of the transaction you’ve just made, and your password is your privateToken .
