Gnosis Transaction Service

Keeps track of transactions sent via Gnosis Safe contracts. It uses events and tracing to index the txs.

Transactions are detected in an automatic way, so there is no need of informing the service about the transactions as in previous versions of the Transaction Service.

Transactions can also be sent to the service to allow offchain collecting of signatures or informing the owners about a transaction that is pending to be sent to the blockchain.

Setup for production

This is the recommended configuration for running a production Transaction service. docker-compose is required for running the project.

Configure the parameters needed on .env. These parameters need to be changed:

• ETHEREUM_NODE_URL: Http/s address of a ethereum node. It can be the same than ETHEREUM_TRACING_NODE_URL.
• ETHEREUM_TRACING_NODE_URL: Http/s address of a Ethereum Parity node with tracing enabled.

If you need the Usd conversion for tokens don't forget to configure:

• ETH_UNISWAP_FACTORY_ADDRESS: Checksummed address of Uniswap Factory contract.
• ETH_KYBER_NETWORK_PROXY_ADDRESS: Checksummed address of Kyber Network Proxy contract.

If you don't want to use trace_filter for the internal tx indexing and just rely on trace_block, set:

• ETH_INTERNAL_NO_FILTER=1

For more parameters check base.py file.

Then:

docker-compose build --force-rm
docker-compose up

The service should be running in localhost:8000. You can test everything is set up:

curl 'http://localhost:8000/api/v1/about/'

For example, to set up a Göerli node:

Run a Parity node in your local computer:

parity --chain goerli --tracing on --db-path=/media/ethereum/parity --unsafe-expose

Edit .env so docker points to he host Parity:

ETHEREUM_NODE_URL=http://172.17.0.1:8545
ETHEREUM_TRACING_NODE_URL=http://172.17.0.1:8545

Then:

docker-compose build --force-rm
docker-compose up
