+## Spark (L2)
+
+Spark L2 is a self-custodial funding source that uses a small Node.js sidecar to talk to the Spark network and expose an HTTP API. You can let LNbits run the sidecar internally, or run it yourself and point LNbits at it.
+
+**Required env vars**
+
+- `LNBITS_BACKEND_WALLET_CLASS`: `SparkL2Wallet`
+
+**Internal sidecar (LNbits-managed)**
+
+- `SPARK_L2_INTERNAL_SIDECAR_VERSION`: `0.1.1`
+- `SPARK_L2_MNEMONIC`: `...` (optional; auto-generated if blank)
+- `SPARK_L2_NETWORK`: `MAINNET`
+
+Optional tuning:
+
+- `SPARK_L2_PAY_WAIT_MS`: `4000`
+- `SPARK_L2_PAY_POLL_MS`: `500`
+- `SPARK_L2_STREAM_KEEPALIVE_MS`: `15000`
+
+**External sidecar**
+
+- `SPARK_L2_EXTERNAL_ENDPOINT`: `http://127.0.0.1:8765`
+- `SPARK_L2_EXTERNAL_API_KEY`: `...` (if your sidecar requires auth)
+
+Example: run the sidecar manually (external mode)
+
+```bash
+git clone https://github.com/lnbits/spark_sidecar.git
+cd spark_sidecar
+npm install
+
+SPARK_MNEMONIC="bottom bottom bottom bottom bottom bottom bottom bottom bottom bottom bottom bottom" \
+SPARK_NETWORK=MAINNET \
+SPARK_SIDECAR_PORT=8765 \
+SPARK_PAY_WAIT_MS=20000 \
+node server.mjs
+```
+
+For testing, you can generate a 12-word mnemonic at `https://iancoleman.io/bip39/`. Store it securely — it controls your funds. Then select **Spark (L2)** as the funding source in LNbits.
