./deeper-chain --dev
```
2. start a dev api sidecar server
```bash
docker run --rm -it --read-only -e SAS_SUBSTRATE_URL=ws://172.17.0.1:9955 -p 8080:8080 docker.io/parity/substrate-api-sidecar:v13.1.0

## architecture
This package uses `txwrapper-deeper` to submit extrinsics offline, `txwrapper-deeper` helps you encode payload and generate signature of this payload, it's very tedious if you do it manually. Note `txwrapper-deeper` is wrapper for deeper-chain, if you want to submit to other chain, create your own `txwrapper-{YOUR CHAIN}`. You can follow instructions at [https://github.com/paritytech/txwrapper-core](https://github.com/paritytech/txwrapper-core).
If you want to know how to generate signed transaction payload manually, check [https://github.com/paritytech/polkadot-interaction-examples-rs/blob/main/src/bin/05_transfer_balance.rs](https://github.com/paritytech/polkadot-interaction-examples-rs/blob/main/src/bin/05_transfer_balance.rs)
