+# Incident Response Runbook – YieldVault RPC & Delivery Failures
+
+## 1. Overview
+This runbook documents the operational procedures for handling **RPC degradation**, **delivery (transaction) failures**, and the **recovery** steps required to restore normal service for the YieldVault smart‑contract platform.
+
+---
+## 2. Detection & Alerting
+| Metric / Log | Threshold | Alert Destination |
+|--------------|-----------|-------------------|
+| `rpc_latency_ms` (average over 1 min) | > 1500 ms | PagerDuty / Slack `#ops` |
+| `rpc_error_rate` (errors / total calls) | > 5 % | PagerDuty / Slack |
+| `tx_delivery_failure_rate` (failed deliveries / total) | > 2 % | PagerDuty / Slack |
+| `node_sync_lag` (blocks behind head) | > 10 blocks | PagerDuty |
+
+*Metrics are collected via Prometheus exporters on each validator node and aggregated in Grafana.*
+
+---
+## 3. Symptom Checklist
+### RPC Degradation
+- Increased response times for `GET /rpc/*` endpoints.
+- Spike in `500`/`504` HTTP status codes.
+- Clients report time‑outs when calling contract methods.
+
+### Delivery Failures
+- Transactions submitted to the network return `TxFailed` or are not included in the next ledger.
+- `tx_delivery_failure_rate` metric exceeds the threshold.
+- Users see “insufficient fee” or “sequence number too low” errors.
+
+---
+## 4. Immediate Triage (First 15 min)
+1. **Acknowledge alert** in the incident channel.
+2. **Validate scope** – check if the issue is isolated to a single node or cluster‑wide.
+3. **Gather logs**:
+   ```bash
+   journalctl -u soroban-node -n 200 | grep -i "rpc" > /tmp/rpc_logs.txt
+   ```
+4. **Check node health**:
+   ```bash
+   curl -s http://localhost:8000/metrics | grep -E "rpc_latency|rpc_error_rate"
+   ```
+5. **Confirm network health** – run a simple health‑check transaction:
+   ```rust
+   // minimal contract call to a known address
+   ```
+   If it fails, the problem is likely network‑wide.
+
+---
+## 5. Mitigation Steps
+### 5.1 RPC Degradation
+- **Scale‑out**: Deploy an additional validator node and add it to the load‑balancer pool.
+- **Restart overloaded node**:
+  ```bash
+  systemctl restart soroban-node
+  ```
+- **Throttle traffic**: Adjust the NGINX/HAProxy rate‑limit to 200 req/s per IP.
+- **Enable cache** for read‑only RPC calls (e.g., `getLedgerEntries`).
+
+### 5.2 Delivery Failures
+- **Increase fee bump**: Re‑submit pending transactions with a higher fee using the `fee-bump` utility.
+- **Resubmit pending queue**: Flush the local transaction queue after confirming the node is in sync.
+- **Check ledger sync**: If `node_sync_lag` > 10, trigger a **state sync** from a healthy peer:
+  ```bash
+  soroban-node sync --source <healthy-node>
+  ```
+- **Temporarily disable new submissions**: Set the API flag `accept_tx = false` to stop inflow while you recover.
+
+---
+## 6. Recovery Procedure (After Mitigation)
+1. **Verify metrics** have returned below thresholds for at least 5 minutes.
+2. **Run a smoke‑test suite** (included in `contracts/vault/tests/`):
+   ```bash
+   cargo test --workspace --quiet
+   ```
+3. **Re‑enable transaction ingestion** (`accept_tx = true`).
+4. **Monitor** for any residual errors for the next 30 minutes.
+5. **Document** the incident timeline, root cause, and actions taken in the post‑mortem.
+
+---
+## 7. Post‑mortem & Continuous Improvement
+- Complete the **Post‑mortem Template** (`docs/POSTMORTEM_TEMPLATE.md`).
+- Update runbook if new failure modes were discovered.
+- Review alert thresholds and adjust if false‑positives occurred.
+- Schedule a **runbook drill** quarterly.
