Tools for exporting Loom blockchain data to CSV or JSON

Ethereum ETL

Ethereum ETL lets you convert blockchain data into convenient formats like CSVs and relational databases.

Do you just want to query Ethereum data right away? Use the public dataset in BigQuery.

Full documentation available here.

Quickstart

Install Ethereum ETL:

pip3 install ethereum-etl

Export blocks and transactions (Schema, Reference):

> ethereumetl export_blocks_and_transactions --start-block 0 --end-block 500000 \
--blocks-output blocks.csv --transactions-output transactions.csv \
--provider-uri https://mainnet.infura.io/v3/239a1d18eba14f0f9dc1c882de0dc872

Export ERC20 and ERC721 transfers (Schema, Reference):

> ethereumetl export_token_transfers --start-block 0 --end-block 500000 \
--provider-uri file://$HOME/Library/Ethereum/geth.ipc --output token_transfers.csv

Export traces (Schema, Reference):

> ethereumetl export_traces --start-block 0 --end-block 500000 \
--provider-uri file://$HOME/Library/Ethereum/parity.ipc --output traces.csv

---

Stream blocks, transactions, logs, token_transfers continually to console (Reference):

> pip3 install ethereum-etl[streaming]
> ethereumetl stream --start-block 500000 -e block,transaction,log,token_transfer --log-file log.txt \
--provider-uri https://mainnet.infura.io/v3/239a1d18eba14f0f9dc1c882de0dc872

Running in Docker

1. Install Docker https://docs.docker.com/install/

2. Build a docker image

    > docker build -t ethereum-etl:latest .
    > docker image ls
   

3. Run a container out of the image

    > docker run -v $HOME/output:/ethereum-etl/output ethereum-etl:latest export_all -s 0 -e 5499999 -b 100000 -p https://mainnet.infura.io
    > docker run -v $HOME/output:/ethereum-etl/output ethereum-etl:latest export_all -s 2018-01-01 -e 2018-01-01 -p https://mainnet.infura.io
   

4. Run streaming to console or Pub/Sub

    > docker build -t ethereum-etl:latest -f Dockerfile .
    > echo "Stream to console"
    > docker run ethereum-etl:latest stream --start-block 500000 --log-file log.txt
    > echo "Stream to Pub/Sub"
    > docker run -v /path_to_credentials_file/:/ethereum-etl/ --env GOOGLE_APPLICATION_CREDENTIALS=/ethereum-etl/credentials_file.json ethereum-etl:latest stream --start-block 500000 --output projects/<your-project>/topics/crypto_ethereum
