-1. **Epico RPC**  
+1. **Epico RPC**
    This module, embedded within the client, exposes Ethereum JSON-RPC methods. It acts as a “mask,” presenting a Substrate node as a standard Ethereum node to external clients and tools.

-2. **Epico Pallet**  
+2. **Epico Pallet**

+3. **Epico Pallet Runtime APIs**
    These APIs provide an interface between the runtime and the Epico RPC client, retrieving the necessary data (balance, nonce, block info, etc.) for Ethereum-compatible RPC responses.
 
+4. **Epico Receipt Service**
+   An offchain service that manages transaction receipts in persistent storage. It runs two workers: one stores receipts as "untrusted" on block import, another promotes them to "finalized" on finality events. Features automatic garbage collection that follows the node's state pruning configuration and gap-filling for missed events. Essential for Ethereum RPC compatibility.

 In addition, Epico leverages a custom `UncheckedExtrinsic` and `CheckedExtrinsic` flow (inspired by Frontier) to handle validation, pre-dispatch, dispatch, and post-dispatch logic for transactions submitted through the Epico RPC.

+## Step 7: Add Receipt Service for Transaction Receipt Storage
+
+The `epico-receipt-service` is an offchain service that manages transaction receipts in persistent storage. It runs two workers: one stores receipts as "untrusted" on block import, another promotes them to "finalized" on finality events.
+
+1. Add the `epico-receipt-service` dependency in your **node's** `Cargo.toml` file:
+
+   ```toml
+   [dependencies]
+   epico-receipt-service = { workspace = true }
+   ```
+
+2. Initialize and spawn the receipt service in your node's service setup (e.g., `node/src/service.rs`):
+
+   ```rust
+   use epico_receipt_service::ReceiptService;
+
+   // In your service setup function
+   let receipt_service = ReceiptService::<_, Block, solochain_template_runtime::Runtime, _>::new(
+       &config,
+       client.clone(),
+       backend
+           .offchain_storage()
+           .ok_or_else(|| "Offchain storage not available")?,
+   );
+
+   task_manager.spawn_handle().spawn(
+       "receipt-service-offchain-workers-runner",
+       "receipt-service-offchain-worker",
+       receipt_service.run(task_manager.spawn_handle()).boxed(),
+   );
+   ```
+
+**Note**: The `build_receipt_at` runtime API method required by this service has already been added to the runtime API implementation in Step 4.
+
+---
+
 ## Summary checklist
 
 1. Add `Epico` dependencies to `Cargo.toml`.
 2. Integrate AccountId20 into your runtime.
 3. Add the `pallet-epico` implementation to the runtime.
 4. Integrate the `ep-self-contained` package into your runtime.
-5. Set up the RPC for Ethereum compatibility
+5. Set up the RPC for Ethereum compatibility.
