-## Automated Script Status
-
-### Scripts Created
-
-1. **`scripts/configure-letsencrypt-cert.sh`**
-   - ✅ Authentication working
-   - ⚠️ API returns empty proxy hosts list
-   - Status: Needs proxy host to exist in API
-
-2. **`scripts/configure-letsencrypt-cert-db.sh`**
-   - ⚠️ Database path needs verification
-   - Status: Database location unclear
-
-### Recommendation
-
-**Use manual configuration via web UI** - it's the most reliable method and takes only 2-3 minutes.
-
----
-
-## Troubleshooting
-
-### If Certificate Request Fails
-
-1. **Check DNS**: Ensure `explorer.d-bis.org` resolves to `76.53.10.36`
-   ```bash
-   dig +short explorer.d-bis.org A
-   ```
-
-2. **Check Port Forwarding**: Ensure ports 80/443 are forwarded correctly
-   - UDM Pro → 192.168.11.167:80/443
-
-3. **Check Firewall**: Ensure UDM Pro allows Let's Encrypt validation
-   - Let's Encrypt needs access to port 80 for validation
-
-4. **Check NPMplus Logs**:
-   ```bash
-   ssh root@r630-01
-   pct exec 10233 -- docker logs npmplus --tail 50 | grep -i cert
-   ```
-
-### If Certificate Exists But Not Working
-
-1. **Check Certificate Status** in NPMplus dashboard
-2. **Verify Certificate is Assigned** to proxy host
-3. **Check NPMplus nginx** is reloaded
-4. **Wait 30 seconds** after assignment
-
----
-
-## Summary
-
-**Status**: ⚠️ **MANUAL CONFIGURATION REQUIRED**
-
-**Action**: 
-1. Access NPMplus dashboard at `https://192.168.11.167:81`
-2. Login with credentials from `.env` file
-3. Create Let's Encrypt certificate for `explorer.d-bis.org`
-4. Assign certificate to proxy host
-5. Enable Force SSL and HTTP/2
-
-**Time Required**: 2-3 minutes
-
----
-
-**Next Step**: Access NPMplus dashboard and configure certificate manually

-# Net1 Removed - Issue Analysis
-
-**Date**: 2026-01-21  
-**Status**: ⚠️ **ISSUE** - 192.168.11.166 still not accessible after net1 removal
-
----
-
-## Current Situation
-
-### Configuration
-- ✅ **net1 removed**: Container now has only eth0 (192.168.11.166)
-- ✅ **Docker network**: Bridge mode with port mappings
-- ✅ **docker-proxy**: Listening on 0.0.0.0:80/443/81
-- ✅ **Routing**: Clean (only eth0 route)
-- ❌ **192.168.11.166**: Not accessible (HTTP 000)
-- ⚠️ **Docker container**: Starting (health: starting)
-
----
-
-## Analysis
-
-### What's Working
-1. **Container network**: Clean single interface (eth0)
-2. **Docker port mappings**: Correct (0.0.0.0:80/443/81)
-3. **docker-proxy**: Running and listening
-
-### What's Not Working
-1. **192.168.11.166**: Not accessible from outside
-2. **localhost:80**: Not accessible from inside container
-3. **Docker container health**: Starting (may need more time)
-
----
-
-## Possible Causes
-
-### 1. NPMplus Not Fully Started
-- Container health shows "starting"
-- NPMplus may need more time to initialize
-- Nginx inside container may not be running yet
-
-### 2. Docker Container Internal Issue
-- NPMplus nginx may not be listening inside container
-- Container may be in unhealthy state
-- Need to check container logs
-
-### 3. Network Namespace Issue
-- Docker bridge network may have routing issues
-- Port forwarding may not be working correctly
-- Need to verify iptables rules
-
----
-
-## Diagnostic Steps
-
-### Step 1: Wait for Container to Fully Start
-```bash
-# Wait 30-60 seconds for NPMplus to fully initialize
-# Check health status
-docker ps --filter name=npmplus --format "{{.Status}}"
-```
-
-### Step 2: Check NPMplus Processes
-```bash
-docker exec npmplus ps aux | grep nginx
-docker exec npmplus ps aux | grep node
-```
-
-### Step 3: Check NPMplus Logs
-```bash
-docker logs npmplus --tail 50
-```
-
-### Step 4: Test Direct Connection to Docker Container IP
-```bash
-# Get container IP
-docker inspect npmplus --format "{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}"
-
-# Test connection
-curl -I http://<container-ip>:80
-```
-
-### Step 5: Check Docker Network
-```bash
-docker network inspect bridge
-docker port npmplus
-```
-
----
-
-## Recommended Actions
-
-### Immediate
-1. **Wait 30-60 seconds** for NPMplus to fully start
-2. **Check container health** status
-3. **Review container logs** for errors
-
-### If Still Not Working
-1. **Check NPMplus nginx** is running inside container
-2. **Verify Docker port mappings** are correct
-3. **Test direct connection** to Docker container IP (172.17.0.2)
-4. **Check iptables rules** for port forwarding
-
-### Alternative Solution
-If 192.168.11.166 continues to have issues:
-- **Re-add net1** temporarily
-- **Use 192.168.11.167** (which was working)
-- **Update UDM Pro** to use 192.168.11.167
-
----
-
-## Next Steps
-
-1. ✅ Wait for container to fully start (30-60 seconds)
-2. ✅ Check NPMplus processes and logs
-3. ✅ Test direct connection to Docker container IP
-4. ✅ If still failing, consider re-adding net1 or investigating Docker networking
-
----
-
-**Status**: ⏳ **WAITING** - Container may need more time to fully start
-
-**Action**: Wait and re-test, then check container logs if still failing

-
----
-
-## Update Steps (Detailed)
-
-### Step 1: Backup (Critical!)
-
-```bash
-# On Proxmox host (r630-01)
-ssh root@r630-01
-
-# Create backup directory
-mkdir -p /data/npmplus-backups
-
-# Backup from container
-docker exec npmplus tar -czf /tmp/npmplus-backup-$(date +%Y%m%d_%H%M%S).tar.gz -C /data .
-docker cp npmplus:/tmp/npmplus-backup-*.tar.gz /data/npmplus-backups/
-docker exec npmplus rm -f /tmp/npmplus-backup-*.tar.gz
-
-# Verify backup
-ls -lh /data/npmplus-backups/
-```
-
-### Step 2: Pull New Image
-
-```bash
-# Pull new image (may take 2-5 minutes)
-docker pull zoeyvid/npmplus:2026-01-20-r2
-
-# Verify image
-docker images | grep npmplus
-```
-
-### Step 3: Stop and Remove Old Container
-
-```bash
-# Stop container
-docker stop npmplus
-
-# Remove container (volumes are preserved)
-docker rm npmplus
-```
-
-### Step 4: Create New Container
-
-```bash
-# Create new container with updated image
-docker run -d \
-  --name npmplus \
-  --restart unless-stopped \
-  --network bridge \
-  -p 80:80 \
-  -p 443:443 \
-  -p 81:81 \
-  -v /data/npmplus:/data \

-  zoeyvid/npmplus:2026-01-20-r2
-```
-
-### Step 5: Verify Update
-
-```bash
-# Check container status
-docker ps --filter name=npmplus
-
-# Check version
-docker inspect npmplus --format '{{.Config.Image}}'
-
-# Test accessibility
-curl -I http://192.168.11.167:80
-curl -I https://192.168.11.167:81 -k
-
-# Test proxy functionality
-curl -H "Host: explorer.d-bis.org" http://192.168.11.167:80
-```
-
----
-
-## Post-Update Tasks
-
-### 1. Verify NPMplus Dashboard
-
-- Access: `https://192.168.11.167:81`
-- Login with credentials
-- Check that all proxy hosts are still configured
-
-### 2. Recreate Certificates (If Using PowerDNS)
-
-**⚠️ Important**: If you were using PowerDNS DNS plugin, certificates need to be **recreated** (not renewed):
-
-1. Go to SSL Certificates
-2. Delete old certificates that used PowerDNS
-3. Create new Let's Encrypt certificates
-4. Reassign to proxy hosts
-
-### 3. Test External Access
-
-```bash
-# From external network
-curl -I https://explorer.d-bis.org
-
-# Should work without SSL errors (if certificate is configured)
-```
-
----
-
-## Troubleshooting
-
-### If Container Fails to Start
-
-1. **Check logs**:
-   ```bash
-   docker logs npmplus --tail 50
-   ```
-
-2. **Check volumes**:
-   ```bash
-   docker inspect npmplus --format '{{range .Mounts}}{{.Source}}:{{.Destination}} {{end}}'
-   ```
-
-3. **Restore from backup** (if needed):
-   ```bash
-   docker stop npmplus
-   docker rm npmplus
-   # Restore backup
-   docker run -d --name npmplus --restart unless-stopped \
-     --network bridge -p 80:80 -p 443:443 -p 81:81 \
-     -v /data/npmplus:/data -v /data/letsencrypt:/etc/letsencrypt \
-     zoeyvid/npmplus:latest
-   ```
-
-### If Network Timeout During Pull
-
-1. **Pull from Proxmox host** (better network):
-   ```bash
-   ssh root@r630-01
-   docker pull zoeyvid/npmplus:2026-01-20-r2
-   ```
-
-2. **Import to container's Docker**:
-   ```bash
-   docker save zoeyvid/npmplus:2026-01-20-r2 | \
-     pct exec 10233 -- docker load
-   ```
-
-### If Proxy Hosts Missing
-
-Proxy hosts are stored in the database, so they should persist. If missing:
-
-1. Check NPMplus dashboard
-2. Verify database is mounted correctly
-3. Restore from backup if needed
-
----
-
-## Rollback (If Needed)
-
-If the update causes issues:
-
-```bash
-# Stop new container
-docker stop npmplus
-docker rm npmplus
-
-# Restore old image
-docker run -d \
-  --name npmplus \
-  --restart unless-stopped \
-  --network bridge \
-  -p 80:80 \
-  -p 443:443 \
-  -p 81:81 \
-  -v /data/npmplus:/data \
-  -v /data/letsencrypt:/etc/letsencrypt \
-  zoeyvid/npmplus:latest
-```
-
----
-
-## Summary
-
-**Status**: ⚠️ **READY TO UPDATE**
-
-**Recommended Method**: Manual update on Proxmox host (Method 1)
-
-**Time Required**: 5-10 minutes
-
-**Risk Level**: Low (backup created, volumes preserved)

-- **Production (canonical target):** the current **Next.js standalone frontend** in `frontend/src/`, built from `frontend/` with `npm run build` and deployed to VMID 5000 as a Node service behind nginx.
-- **Canonical deploy script:** `./scripts/deploy-next-frontend-to-vmid5000.sh`
-- **Canonical nginx wiring:** keep `/api`, `/api/config/*`, `/explorer-api/*`, `/token-aggregation/api/v1/*`, `/snap/`, and `/health`; proxy `/` and `/_next/` to the frontend service using `deployment/common/nginx-next-frontend-proxy.conf`.
-- **Legacy fallback only:** the static SPA (`frontend/public/index.html` + `explorer-spa.js`) remains in-repo for compatibility/reference, but it is not a supported primary deployment target.
-- **Architecture command center:** `frontend/public/chain138-command-center.html` — tabbed Mermaid topology (Chain 138 hub, network, stack, flows, cross-chain, cW Mainnet, off-chain, integrations). Linked from the SPA **More → Explore → Visual Command Center**.
-- **Legacy static deploy scripts:** `./scripts/deploy-frontend-to-vmid5000.sh` and `./scripts/deploy.sh` now fail fast with a deprecation message and point to the canonical Next.js deploy path.

 ## Configuration
 
-- **Database User:** `explorer`
-- **Database Password:** `***REDACTED-LEGACY-PW***`
-- **RPC URL:** `http://192.168.11.250:8545`
-- **Chain ID:** `138`
-- **Port:** `8080`
+Every credential, URL, and RPC endpoint is an env var. There is no
+in-repo production config. Minimum required by a non-dev binary:
 
-## Reusable libs (extraction)
+| Var | Purpose | Notes |
+|-----|---------|-------|
+| `JWT_SECRET` | HS256 wallet-auth signing key | Fail-fast if empty |
+| `CSP_HEADER` | `Content-Security-Policy` response header | Fail-fast if empty |
+| `DB_HOST` / `DB_PORT` / `DB_USER` / `DB_PASSWORD` / `DB_NAME` | Postgres connection | |
+| `REDIS_HOST` / `REDIS_PORT` | Redis cache | |
+| `ELASTICSEARCH_URL` | Indexer / search backend | |
+| `RPC_URL` / `WS_URL` | Upstream Chain 138 RPC | |
+| `RPC_PRODUCTS_PATH` | Optional override for `backend/config/rpc_products.yaml` | PR #7 |
 
-Reusable components live under `backend/libs/` and `frontend/libs/` and may be split into separate repos and linked via **git submodules**. Clone with submodules:
-
-```bash
-git clone --recurse-submodules <repo-url>
-# or after clone:
-git submodule update --init --recursive
-```
-
-See [docs/REUSABLE_COMPONENTS_EXTRACTION_PLAN.md](docs/REUSABLE_COMPONENTS_EXTRACTION_PLAN.md) for the full plan.
+Full list: `deployment/ENVIRONMENT_TEMPLATE.env`.
 
 ## Testing
 
-- **All unit/lint:** `make test` — backend `go test ./...` and frontend `npm test` (lint + type-check).
-- **Backend:** `cd backend && go test ./...` — API tests run without a real DB; health returns 200 or 503, DB-dependent endpoints return 503 when DB is nil.
-- **Frontend:** `cd frontend && npm run build` or `npm test` — Next.js build (includes lint) or lint + type-check only.
-- **E2E:** `make test-e2e` or `npm run e2e` from repo root — Playwright tests against https://blockscout.defi-oracle.io by default; use `EXPLORER_URL=http://localhost:3000` for local.
+```bash
+# Unit tests + static checks
+cd backend && go test ./... && staticcheck ./... && govulncheck ./...
+cd frontend && npm test && npm run test:unit
 
-## Status
+# Production canary
+EXPLORER_URL=https://explorer.d-bis.org make test-e2e
 
-✅ All implementation complete  
-✅ All scripts ready  
-✅ All documentation complete  
-✅ Frontend: C1–C4, M1–M4, H4, H5, L2, L4 done; H1/H2/H3 (escapeHtml/safe href) in place; optional L1, L3 remain  
-✅ CI: backend + frontend tests; lint job runs `go vet`, `npm run lint`, `npm run type-check`  
-✅ Tests: `make test`, `make test-e2e`, `make build` all pass  
+# Full local stack + Playwright
+make e2e-full

-# ChainID 138 Explorer+ and Virtual Banking VTM Platform
-
-## 1. Objective
-Build a next-generation, cross-chain blockchain intelligence and interaction platform that:
-- Starts as a **ChainID 138** explorer (Blockscout-class) and expands into a **multi-chain, multi-protocol** explorer.
-- Adds **transaction interaction** features (swap/bridge/on-ramp/off-ramp, account management, signing workflows) comparable to wallet suites.
-- Integrates **Virtual Banking Tellers** via **Soul Machines** to deliver a Virtual Teller Machine (VTM) experience.
-- Uses **Chainlink CCIP DON** for secure cross-chain messaging/bridging coordination and observability.
-- Supports **Solace Bank Group** digital banking UX with compliant identity, account, and payment rails.
-- Delivers a **bleeding-edge UX** including XR / metaverse-like environments where appropriate.
-
-## 2. Product Scope
-### 2.1 Core Pillars
-1) **Explorer & Indexing** (Blockscan/Etherscan/Blockscout parity)
-2) **Mempool & Real-time** (pending tx, propagation, bundle tracking)
-3) **Cross-chain Intelligence** (entity graph, address attribution, unified search)
-4) **Action Layer** (swap/bridge, token tools, contract deploy/verify, portfolio)
-5) **Banking & Compliance** (KYC/KYB, risk, limits, ledger, fiat rails)
-6) **Virtual Teller Machine** (Soul Machines-based digital humans + workflow automation)
-7) **XR Experience** (optional immersive interfaces for exploration + teller workflows)
-
-### 2.2 Non-goals (initial)
-- Operating as a custodial exchange (unless licensed and separately scoped)
-- Providing investment advice or trading signals beyond analytics
-
-## 3. Target Users and Use Cases
-- **Developers**: contract verification, ABI decoding, tx debugging, logs, traces
-- **Retail users**: balances, NFTs, swaps, bridges, notifications, address book
-- **Institutions**: compliance dashboards, entity risk, proof-of-funds, audit trails
-- **Bank customers**: virtual teller support, onboarding, account actions, dispute workflows
-
-## 4. Reference Feature Set (What to Match/Surpass)
-### 4.1 Etherscan/Blockscan-class
-- Address/Tx/Block pages, token pages, internal tx, logs, traces, verified contracts
-- Advanced filters, CSV export, APIs, alerts, labels, watchlists
-
-### 4.2 Mempool / “Blockchain.com-like”
-- Pending tx stream, fee estimation, propagation time, RBF/replace-by-fee (where applicable)
-- Bundles/MEV visibility (where supported), private tx markers
-
-### 4.3 Blockscout-class
-- Open-source extensibility: smart contract verification pipelines, sourcify support
-- Multi-chain config and modular indexer
-
-### 4.4 Wallet/Bridge suite
-- Swap routing, bridge routing, cross-chain portfolio, approvals management
-- Integrations (Changelly / AtomicWallet-like UX): quotes, slippage, KYC prompts
-
-## 5. System Architecture (High-Level)
-### 5.1 Component Overview
-- **Frontend**: Web + mobile + XR clients
-- **API Gateway**: unified edge API, auth, rate limits
-- **Explorer Services**: blocks/tx/indexing/search/analytics
-- **Mempool Services**: pending tx ingestion, fee oracle, websockets
-- **Cross-chain Layer**: CCIP coordination, message observability, routing
-- **Action Layer**: swap/bridge orchestration, wallet connect, signing workflows
-- **Banking Layer**: identity, compliance, ledger, payments, customer service
-- **Virtual Teller Layer**: Soul Machines integration + workflow engine
-- **Data Layer**: OLTP + time-series + search + graph + data lake
-- **Ops/Security**: SIEM, KMS/HSM, secrets, audit, monitoring

-## 6. ChainID 138 Explorer Foundation
-### 6.1 Node and Data Sources
-- **Full nodes** for ChainID 138 (archive + tracing if EVM-based)
-- **RPC endpoints** (load-balanced, multi-region)
-- **Indexer** pipelines:
-  - Blocks + tx + receipts
-  - Event logs
-  - Traces (call traces, internal tx)
-  - Token transfers (ERC-20/721/1155)
-
-### 6.2 Indexing Pipeline
-- Ingestion: block listener + backfill workers
-- Decode: ABI registry + signature database
-- Persist: canonical relational schema + denormalized search docs
-- Materialize: analytics aggregates (TPS, gas, top contracts)
-
-### 6.3 Contract Verification
-- Solidity/Vyper verification workflow
-- Sourcify integration
-- Build artifact storage (immutable)
-- Multi-compiler version support
-
-### 6.4 Public APIs
-- REST + GraphQL
-- Etherscan-compatible API surface (optional) for tool compatibility
-- Rate limiting and API keys
-
-## 7. Multi-Chain Expansion
-### 7.1 Chain Abstraction
-Define a chain adapter interface:
-- RPC capabilities (archive, tracing, debug)
-- Token standards
-- Gas model
-- Finality model
-
-### 7.2 Multi-Chain Indexing Strategy
-- Per-chain indexer workers
-- Shared schema with chain_id partitioning
-- Cross-chain unified search
-
-### 7.3 Cross-chain Entity Graph
-- Address clustering heuristics (opt-in labels)
-- Contract/protocol tagging
-- CCIP message links (source tx ↔ message ↔ destination tx)
-
-### 7.4 Cross-chain Observability via CCIP
-- Ingest CCIP message events
-- Normalize message IDs
-- Track delivery status, retries, execution receipts

-- Simulation + signing warnings
-
-## 9. Banking Layer (Solace Bank Group Integration)
-### 9.1 Identity and Compliance
-- KYC/KYB workflow orchestration
-- Sanctions/PEP screening integration points
-- Risk tiers, limits, and step-up verification
-
-### 9.2 Account and Ledger
-- Customer ledger (double-entry)
-- Wallet mapping (customer ↔ addresses)
-- Reconciliation jobs
-- Audit trails and immutable logs
-
-### 9.3 Payments and Fiat Rails
-- On-ramp/off-ramp provider integration
-- ACH/wire/card rails (as available)
-- Settlement monitoring
-
-### 9.4 Compliance Dashboards
-- Case management
-- SAR/STR workflow hooks (jurisdiction-dependent)
-- Evidence export packages
-
-## 10. Virtual Teller Machine (VTM) with Soul Machines
-### 10.1 VTM Concepts
-Replace “chat widget” with a **digital human teller** that:
-- Guides onboarding and identity verification
-- Explains transactions (fees, risk, finality)
-- Initiates actions (swap/bridge) with user consent
-- Handles banking workflows (password reset, dispute intake, limit increase requests)
-
-### 10.2 Integration Architecture
-- Soul Machines Digital Human UI embedded in Web/Mobile/XR
-- Teller Orchestrator connects:
-  - Conversation state
-  - Customer profile/permissions
-  - Workflow engine actions
-  - Human escalation (ticket/call)
-

-
-### 10.3 Teller Workflows (Examples)
-- “Open a wallet and link my account”
-- “Bridge funds from Chain A to ChainID 138”
-- “Explain why my transaction is pending”
-- “Generate proof-of-funds report for a recipient”
-- “Start KYC / continue KYC”
-
-### 10.4 Governance and Guardrails
-- Role-based permissions
-- Mandatory confirmations for financial actions
-- Audit logging of teller-initiated actions
-- Safe completion templates for regulated workflows
-
-## 11. XR / Metaverse-like UX
-### 11.1 Experience Modes
-- **2D Mode**: standard explorer UI with high-performance tables
-- **3D Mode**: optional immersive views:
-  - Block/tx graph spaces
-  - Cross-chain message tunnels (CCIP)
-  - “Bank branch” virtual environment for teller
-
-### 11.2 XR Technical Stack (Option Set)
-- WebXR (browser-based)
-- Unity/Unreal client for high-fidelity experiences
-- Shared backend APIs; XR is a client variant, not a separate system
-
-### 11.3 XR UI Principles
-- Minimal motion sickness (teleport navigation, stable anchors)
-- Accessibility fallback to 2D
-- Real-time data overlays (blocks, mempool)
-
-## 12. Data Architecture
-### 12.1 Storage Choices (Reference)
-- Relational DB (Postgres) for canonical chain data
-- Search (OpenSearch/Elasticsearch) for fast query
-- Time-series (ClickHouse/Timescale) for mempool + metrics
-- Graph DB (Neo4j) for cross-chain entity/message links
-- Data lake (S3-compatible) for history, ML, audits
-
-### 12.2 Data Retention
-- Full chain history retained; hot vs cold tiers
-- Mempool retained short-term (e.g., 7–30 days) with aggregates longer
-
-## 13. Security, Privacy, and Reliability
-### 13.1 Security Controls
-- KMS/HSM for sensitive keys
-- Secrets management
-- Signed builds + SBOM
-- DDoS protection via WAF/CDN
-- Least privilege IAM
-
-### 13.2 Privacy
-- PII separated from public chain data
-- Tokenization/encryption for identity artifacts
-- Regional data residency controls
-
-### 13.3 Reliability
-- Multi-region read replicas
-- Queue-based ingestion
-- Backpressure and reorg handling
-- SLOs: API p95 latency, websocket delivery, indexing lag
-
-## 14. Observability
-- Centralized logging + tracing
-- Indexer lag dashboards
-- CCIP message lifecycle dashboards
-- Transaction funnel analytics (quote→sign→confirm)
-
-## 15. Implementation Roadmap
-### Phase 0 — Foundations (2–4 weeks)
-- ChainID 138 nodes + RPC HA
-- Minimal indexer + explorer UI MVP
-- Search + basic APIs
-
-### Phase 1 — Blockscout+ Parity (4–8 weeks)

-
-## Next Steps
-
-### Immediate (Automatic)
-
-1. **Wait for LINK Token Confirmation**
-   - Check: `cast code 0x0cb0192C056aa425C557BdeAD8E56C7eEabf7acF --rpc-url http://192.168.11.250:8545`
-   - Once confirmed, minting will proceed automatically
-
-2. **Wait for Mint Confirmation**
-   - Once LINK token is confirmed, mint transaction will be processed
-   - Balance will update to 1,000,000 LINK
-
-3. **Fund Bridges**
-   - Once balance is confirmed, bridges will be funded
-   - 10 LINK to each bridge
-
-### Manual Verification (Recommended)
-
-1. **Check Block Explorer**
-   - Visit: https://explorer.d-bis.org
-   - Search: `0x4A666F96fC8764181194447A7dFdb7d471b301C8`
-   - Review recent transactions
-
-2. **Verify LINK Token**
-   ```bash
-   cast code 0x0cb0192C056aa425C557BdeAD8E56C7eEabf7acF --rpc-url http://192.168.11.250:8545
-   ```
-
-3. **Re-run Readiness Check**
-   ```bash
-   ./scripts/full-readiness-check.sh
-   ```
-
----
-

-### ⏳ Remaining Work
-
-1. **LINK Token Confirmation**: Waiting for network
-2. **Token Minting**: Will proceed after confirmation
-3. **Bridge Funding**: Will proceed after minting
-
-### 🎯 Expected Outcome
-
-Once LINK token confirms (typically within a few minutes):
-- ✅ LINK token deployed and verified

----
-
-## Recommendations
-
-### Short-term
-
-1. **Monitor Transactions**
-   - Check block explorer for transaction status
-   - Verify all transactions are included in blocks
-
-2. **Wait for Confirmation**
-   - LINK token deployment typically confirms within 1-5 minutes
-   - Network may have delays
-
-3. **Re-run Checks**
-   - Once LINK confirms, re-run readiness check
-   - Should show all checks passing
-
-### Long-term
-
-1. **Transaction Monitoring Script**
-   - Add automatic transaction status checking
-   - Alert on failures or delays
-
-2. **Retry Logic**
-   - Automatic retry for failed transactions
-   - Exponential backoff for network delays

-**Note**: Transactions are in the mempool. Network confirmation typically takes 1-5 minutes.
-
----
-
-## ⏳ Priority 3: PENDING
-
-### Bridge Funding
-
-**Status**: ⏳ **WAITING FOR LINK TOKEN**
-
-- ⏳ Cannot proceed until LINK token confirms
-- ✅ Script ready: `fund-bridge-contracts.sh`
-- ✅ Will execute automatically once LINK confirms
-
-**Required**: 20 LINK total (10 per bridge)
-
----
-
-## Readiness Check Results
-
-### Before Action Plan
-- **Passed**: 17
-- **Failed**: 3
-- **Warnings**: 2
-
-### After Action Plan
-- **Passed**: 19 ✅ (+2)
-- **Failed**: 1 ⚠️ (-2)
-- **Warnings**: 2
-
-### Improvements
-1. ✅ **Ethereum Mainnet Configuration**: Fixed (was failing, now passing)
-2. ✅ **Bridge Destination Status**: Both bridges now configured
-3. ⏳ **LINK Token**: Deployed but pending confirmation
-
----
-
-## Current System State
-
-### ✅ Fully Operational
-- Network connectivity
-- Account status (999M+ ETH)
-- Bridge contracts deployed
-- **Ethereum Mainnet destinations configured** ✅
-- Configuration files
-- All scripts available
-
-### ⏳ Pending Network Confirmation
-- LINK token deployment
-- LINK token minting
-- Bridge funding (automatic after LINK confirms)
-
----
-
-## Next Steps
-
-### Automatic (Once LINK Confirms)
-1. LINK token will be verified
-2. Mint will be confirmed
-3. Bridges will be funded automatically
-
-### Manual Verification
-```bash
-# Check LINK token
-cast code 0x0cb0192C056aa425C557BdeAD8E56C7eEabf7acF --rpc-url http://192.168.11.250:8545
-
-# Re-run readiness check
-./scripts/full-readiness-check.sh
-```
-
----
-
-## Summary
-
-**Major Achievement**: ✅ **Ethereum Mainnet configuration complete**
-
-This was one of the 3 critical blockers. The system can now route to Ethereum Mainnet once LINK token confirms and bridges are funded.
-
-**Remaining**: LINK token confirmation (network-dependent, typically 1-5 minutes)

-
-**Date**: $(date)  
-**Status**: ✅ **All Fixes Implemented**

-
-## Errors Identified and Fixed
-
-### ❌ Error 1: Ethereum Mainnet Destination Not Configured
-
-**Issue**: WETH9 bridge does not have Ethereum Mainnet configured as destination.
-
-**Status**: ✅ **Fix Script Created**
-
-**Solution**: 
-- Created `scripts/fix-bridge-errors.sh` to configure the destination
-- Script checks current configuration
-- Configures destination if needed
-- Verifies configuration
-
-**Usage**:
-```bash
-./scripts/fix-bridge-errors.sh [private_key] [ethereum_mainnet_bridge_address]
-```
-
-**Note**: Requires the Ethereum Mainnet bridge address to be provided.
-
-### ⚠️ Warning 1: CCIP Fee Calculation Failed
-
-**Issue**: Could not calculate CCIP fee in dry run.
-
-**Status**: ℹ️ **Informational Only**
-
-**Impact**: Low - This is a warning, not an error. The actual bridge transaction will show the required fee.
-
-**Possible Causes**:
-- Bridge may require LINK tokens for fees
-- Fee calculation function may have different signature
-- Network/RPC issues
-
-**Solution**: 
-- Check LINK balance if required
-- Verify bridge contract fee mechanism
-- Actual transaction will reveal fee requirements
-
----
-
-## Fixes Implemented
-
-### 1. Fix Script ✅
-
-**File**: `scripts/fix-bridge-errors.sh`
-
-**Features**:
-- Checks current bridge configuration
-- Configures WETH9 bridge for Ethereum Mainnet
-- Verifies configuration was successful
-- Reports detailed status
-
-**Usage**:
-```bash
-./scripts/fix-bridge-errors.sh [private_key] [ethereum_mainnet_bridge_address]

-
----
-
-## How to Fix
-
-### Step 1: Get Ethereum Mainnet Bridge Address
-
-You need the address of the CCIPWETH9Bridge contract deployed on Ethereum Mainnet.
-
-**Options**:
-1. Check deployment records
-2. Use existing bridge if already deployed
-3. Deploy bridge contract on Ethereum Mainnet first
-
-### Step 2: Run Fix Script
-
-```bash
-./scripts/fix-bridge-errors.sh [private_key] [ethereum_mainnet_bridge_address]
-```
-
-**Example**:
-```bash
-./scripts/fix-bridge-errors.sh 0xYourPrivateKey 0xEthereumMainnetBridgeAddress
-```
-
-### Step 3: Verify Fix
-
-```bash
-# Re-run dry run
-./scripts/dry-run-bridge-to-ethereum.sh 0.1 [address]
-```
-
-All checks should now pass.
-
----
-
-## Manual Fix (Alternative)
-
-If you prefer to configure manually:
-
-```bash
-# Get current nonce
-NONCE=$(cast nonce [your_address] --rpc-url http://192.168.11.250:8545)
-
-# Configure destination
-cast send 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
-  "addDestination(uint64,address)" \
-  5009297550715157269 \
-  [ethereum_mainnet_bridge_address] \
-  --rpc-url http://192.168.11.250:8545 \
-  --private-key [your_private_key] \
-  --gas-price 5000000000 \
-  --nonce $NONCE
-```
-
----
-
-## Verification
-
-After running the fix, verify:
-
-```bash
-# Check destination
-cast call 0x89dd12025bfCD38A168455A44B400e913ED33BE2 \
-  "destinations(uint64)" \
-  5009297550715157269 \
-  --rpc-url http://192.168.11.250:8545
-```
-
-Should return the Ethereum Mainnet bridge address (not zero address).

-const balance = await contract.balanceOf(address);
-const formatted = ethers.utils.formatUnits(balance, 18);
-```
-
-```python
-# Python (web3.py)
-decimals = 18  # Always use 18
-balance = contract.functions.balanceOf(address).call()
-formatted = Web3.fromWei(balance, 'ether')

-## 📋 Remaining Warnings (Non-Critical Style Suggestions)
-
-### Unaliased Plain Imports
-**Status**: ⚠️ **Style suggestions only** - Not errors
-
-**Impact**: None - Compilation succeeds, functionality unaffected
-
-**Files Affected**: Multiple test files and scripts use plain imports like:
-```solidity
-import "forge-std/Test.sol";
-```
-
-**Suggested Style** (optional):
-```solidity
-import {Test} from "forge-std/Test.sol";
-```
-
-**Note**: These are Foundry linter style suggestions. Refactoring all imports would be a large but non-critical task. The code compiles and runs correctly as-is.
