osmosis-txn-replayer

Omsosis txn replayer is a testing tool to replay transactions from mainnet to a local edgenet to simulate mainnet after an upgrade.

How to use the script

1. Run ./start_mainnet_state.sh
2. Before the chain gets fully synced stop the node
3. Run this script e.g go run main.go. Leave it running until after step 5 below.
4. On the current version e.g v25 run osmosisd in-place-testnet osmosis-1 osmo12smx2wdlyttvyzvzg54y2vnqwq2qjateuf7thj --trigger-testnet-upgrade v26. Note the in-place-testnet is created with chain id osmosis-1.
5. Then when the node stope with 3:14PM ERR CONSENSUS FAILURE!!! err="UPGRADE \"v26\" NEEDED at height: 20246428: "
6. Stop the node and recompile the lastest version e.g v26
7. Run this script e.g go run main.go. Again, leave it running while the node is running in step 8.
8. Then run osmosisd start --home=$HOME/.osmosisd --rpc.unsafe --grpc.enable --grpc-web.enable --api.enabled-unsafe-cors --api.enable

Logs

The logs output block height, type of message and txn hash if sucessful, or an error if theres a failure.

Beware of dragons

• Ensure the edgenet is running slower than mainnet by setting timeout_commit = 3s in the config.toml
• Some txns will fail most should pass. You can double-check the transaction status by osmosisd q tx [hash]
