+# fixturenet-eth-tx
+
+A variation of `fixturenet-eth` that automatically generates transactions using `tx-spammer`.
+
+See `stacks/fixturenet-eth/README.md` for more information.
+
+## Containers
+
+* cerc/go-ethereum
+* cerc/lighthouse
+* cerc/fixturenet-eth-geth
+* cerc/fixturenet-eth-lighthouse
+* cerc/tx-spammer
+
+## Deploy the stack
+```
+$ laconic-so --stack fixturenet-eth-tx setup-repositories
+$ laconic-so --stack fixturenet-eth-tx build-containers
+$ laconic-so --stack fixturenet-eth-tx deploy up
+```
+
+## Export the ethdb (optional)
+
+It is easy to export data from the fixturenet for offline processing of the raw ethdb files (eg, by eth-statediff-service) using the `export-ethdb.sh` script.
+
+For example:
+
+```
+❯ app/data/container-build/cerc-fixturenet-eth-lighthouse/scripts/export-ethdb.sh 500
+Waiting for geth to generate DAG.... done
+Waiting for beacon phase0.... done
+Waiting for beacon altair.... done
+Waiting for beacon bellatrix pre-merge.... done
+Waiting for beacon bellatrix merge.... done
+Waiting for block number 500.... done
+Exporting ethdb.... ./ethdb.tgz
+```
