# Modify l2 substrateNode to allow our system continue working if need add new network
## Upgrade runtime(AckAdmins)
Assume current l2 have 2 AckAdmins. We add a new network named cantotestnet.
1. Use deployment branch `frank/removenetwork`
https://github.com/DelphinusLab/delphinus-deployment/pull/28

2. Add new network in `deployment/config/eth-config.ts`:

{
      chainName: "cantotestnet",
      mongodbUrl: "mongodb://localhost:27017",
      syncEventsStep: 2000,
      bufferBlocks: 0,
      gasWarningAmount: "20",
      nativeCurrency: {
        name: "Test Canto",
        symbol: "Canto", // 2-6 characters long
        decimals: 18,
      },
      blockExplorer: "https://testnet.tuber.build/",
      rpcSource: "https://canto-testnet.plexnode.wtf",
      wsSource: "",
      privateKey: secrets.accounts.deployer.priv,
      monitorAccount: "REPLACE-WITH-CLIENT-MONITOR_ACCOUNT",
      deviceId: "7701",
      l2Account: "//Cindy//stash",
      enabled: testnet,
      isSnap: false,
}

Run `npx tsc` in `deployment`

3. In `deployment/config/substrate-account-config.json`:
3.1 Add `//Cindy//stash` to `secret_key_uri` and `pre_funded_seeds`.
3.2 Modify `sudo_account_seed` to `Smith`.

{
  "secret_key_uri": [
    "//Smith",
    "//Frank",
    "//Cindy//stash"
  ],
  "authorities_seeds": [
    "Eve//stash"
  ],
  "pre_funded_seeds": [
    "Smith",
    "Frank",
    "Cindy//stash"
  ],
  "sudo_account_seed": "Smith"
}

4. Run `bash generate-config.sh` in `substrate-node`

5. Increment the `spec_version` to specify the new runtime version.
Modify `substrate-node/runtime/src/lib.rs`:

6. Run `DOCKER_BUILDKIT=1 docker build . -t delphinus-node -f packages/substrate-node/Dockerfile` in `zkcross-backend-lerna` folder again

7. Run `cargo +nightly-2023-01-24 build --locked --release` to generate new build artifacts `node_swap_runtime.compact.wasm`.

Here I use `nightly-2023-01-24` because latest rustup nightly have bugs.

Current l2's `substrate-node/Dockerfile`:

FROM docker.io/paritytech/ci-linux:production as builder

WORKDIR /delphinuslab
COPY . /delphinuslab

ENV CARGO_HOME /delphinuslab/.cargo-home

8. Visit https://polkadot.js.org/apps/ and switch to local node
8.1 Install https://polkadot.js.org/extension/ and create new accounts.
use `import account from pre-existing seed` option to add new account.

existing 12 or 24-word mnemonic seed:
`bottom drive obey lake curtain smoke basket hold race lonely fit walk`
Network:
`Allow use on any chain`
advanced/derivation path:
`//Smith`, `//Frank` and `//Cindy//stash`

A descriptive name for your account:
I suggest using `Smith` for `//Smith`, `Frank` for `//Frank`, etc.

8.2 Click **Developer** and select **Extrinsics** to submit a transaction for the runtime to use the new build artifact.

8.3 Select the administrative **Smith** account.
`Smith` is descriptive name for `//Smith`

8.4 Select the **sudo** pallet and the **sudoUncheckedWeight(call, weight)** function.

8.5 Select **system** and **setCode(code)** as the call to make using the `Smith` account.

8.6 Click **file upload**, then select or drag and drop the compact and compressed WebAssembly file—node_swap_runtime.compact.wasm—that you generated for the updated runtime.

For example, navigate to the ·target/release/wbuild/node-template-runtime· directory and select `node_swap_runtime.compact.wasm` as the file to upload.

8.7 Leave both of the weight parameters set to the default value of 0.

8.8 Click Submit Transaction.

8.9 Review the authorization, then click **Sign and Submit**.

After the transaction is included in a block, the node template version number indicates that the runtime version is now 101.


## Add balance to new l2Account
new l2Account need balance to setkey and addpool later.

1. In https://polkadot.js.org/apps/, click **Accounts** and select **Accounts**
You can see `//Cindy//stash`'s balance is 0
2. 

3. Click **Developer** and select **Extrinsics**

4. Select the administrative **Smith** account.
`Smith` is descriptive name for `//Smith`

5. Select the **sudo** pallet and the **sudo(call)** function.

6. Select **balances** and **setBalance(who, newFree, newReserved)** as the call to make using the `Smith` account.

`Cindy//stash` for `who: LookupSource`
newFree: Compact<Balance>: 1000000unit = 1munit
newReserved: Compact<Balance>: actually you can set it to zero

7. Click **Submit Transaction**.

8. Review the authorization, then click **Sign and Submit**.

After the transaction is included in a block, `Cindy//stash` has balance now.

## Operate on ui
Cantotestnet can work well:
