Summary

Adds Sepolia testnet support to AutistMask.

Changes

  • New src/shared/networks.js — centralized network definitions (mainnet + Sepolia) with chain IDs, default RPC/Blockscout endpoints, and block explorer URLs
  • State management — networkId added to persisted state; defaults to mainnet for backward compatibility
  • Settings UI — network selector dropdown lets users switch between Ethereum Mainnet and Sepolia Testnet
  • Dynamic explorer links — all hardcoded etherscan.io URLs replaced with dynamic links from the current network config (sepolia.etherscan.io for Sepolia)
  • Background service — wallet_switchEthereumChain now accepts both mainnet (0x1) and Sepolia (0xaa36a7); broadcasts chainChanged to connected dApps
  • Inpage provider — fetches chain ID on init and updates dynamically via chainChanged events (no more hardcoded 0x1)
  • Blockscout API — uses eth-sepolia.blockscout.com/api/v2 for Sepolia
  • Etherscan labels — phishing/scam checks use the correct explorer per network
  • Price fetching — skipped on testnets (testnet tokens have no real market value)
  • RPC validation — checks against the selected network's chain ID, not hardcoded mainnet
  • ethers provider — getProvider() uses the correct ethers Network for Sepolia

Add support for the Sepolia testnet alongside Ethereum mainnet:

- New src/shared/networks.js with network definitions (mainnet + sepolia)
  including chain IDs, default RPC/Blockscout endpoints, and explorer URLs
- State now tracks networkId; defaults to mainnet for backward compatibility
- Network selector in Settings lets users switch between mainnet and Sepolia
- Switching networks updates RPC URL, Blockscout URL, and chain ID
- All hardcoded etherscan.io URLs replaced with dynamic explorer links
  from the current network config (sepolia.etherscan.io for Sepolia)
- Background handles wallet_switchEthereumChain for both supported chains
  and broadcasts chainChanged events to connected dApps
- Inpage provider fetches chain ID on init and updates dynamically via
  chainChanged events (no more hardcoded 0x1)
- Blockscout API uses eth-sepolia.blockscout.com for Sepolia
- Etherscan label/phishing checks use the correct explorer per network
- Price fetching skipped on testnets (tokens have no real value)
- RPC validation checks against the selected network's chain ID
- getProvider() uses the correct ethers Network for Sepolia

API endpoints verified:

Code Review: PR #137 — feat: add Sepolia testnet support

Reviewer: clawbot (automated)
Verdict: ✅ Approve — clean, well-structured PR

Summary

Adds Sepolia testnet as a second supported network with a clean network abstraction layer (src/shared/networks.js), UI network switcher in settings, and dynamic explorer URLs throughout.

Correctness ✅

  • Sepolia chain ID 0xaa36a7 (11155111) is correct
  • Mainnet chain ID 0x1 preserved correctly
  • wallet_switchEthereumChain properly handles switching between supported networks and returns 4902 for unsupported ones
  • wallet_addEthereumChain returns success for already-supported chains per EIP-3085
  • net_version dynamically returns the correct network version string
  • broadcastChainChanged correctly notifies all tabs on network switch

Completeness ✅

  • All hardcoded etherscan.io references in production code replaced with currentNetwork().explorerUrl (verified via grep — only comments and test fixtures remain, which is correct)
  • New networks.js module cleanly centralizes network definitions
  • State persistence includes networkId with backward-compatible default to "mainnet"
  • Price fetching correctly skipped on testnets (isTestnet check in prices.js)
  • Inpage provider fetches chain ID on load and updates dynamically via chainChanged events

Edge Cases ✅

  • Backward compatibility: loadState() defaults networkId to "mainnet" when missing — existing users unaffected
  • Network switching: Settings UI updates RPC + Blockscout URLs to network defaults on switch
  • Inpage provider: chainChanged event properly updates both chainId and networkVersion properties
  • Circular dependency: balances.js uses lazy require() for state to avoid circular imports — good pattern

Code Quality ✅

  • No debug code, console.logs, or TODOs
  • Consistent style with existing codebase
  • explorerLink() helper exported but could be used more (minor, not blocking)
  • Clean separation: network config in networks.js, state management in state.js

Security ✅

  • No credentials or secrets in the diff
  • No unsafe patterns
  • Etherscan label checking correctly uses dynamic explorer URL

Build ✅

  • docker build . passes (includes make check → tests, lint, fmt)

No changes needed. This is ready for merge.

Independent Code Review: PR #137 — Sepolia testnet support

Reviewer: clawbot (independent review)
Verdict: ✅ PASS

Summary

Clean, well-structured single-commit PR that adds Sepolia testnet support with a centralized network abstraction layer. All changes are directly relevant to issue #110.

Network Definitions ✅

  • src/shared/networks.js correctly defines both networks:
    • Mainnet: chain ID 0x1, RPC publicnode.com, Blockscout eth.blockscout.com, explorer etherscan.io
    • Sepolia: chain ID 0xaa36a7 (11155111 decimal — correct), RPC ethereum-sepolia-rpc.publicnode.com, Blockscout eth-sepolia.blockscout.com, explorer sepolia.etherscan.io
  • All endpoints are real, publicly available services

State Management ✅

  • networkId added to persisted state with backward-compatible default to "mainnet"
  • currentNetwork() helper correctly reads state.networkId and returns network config
  • saveState()/loadState() properly persist and restore networkId
  • Network switching in settings updates rpcUrl and blockscoutUrl to network defaults

Explorer URL Migration ✅

  • Verified all 19 files changed — every hardcoded etherscan.io reference in production code replaced with currentNetwork().explorerUrl
  • Remaining etherscan.io strings are only in network definitions and comments — correct
  • All view files (home, addressDetail, addressToken, approval, confirmTx, receive, send, settings, transactionDetail, txStatus) properly use dynamic explorer URLs

Background Script / EIP-1193 ✅

  • eth_chainId returns currentNetwork().chainId dynamically
  • net_version returns currentNetwork().networkVersion dynamically
  • wallet_switchEthereumChain correctly handles switching between supported networks and returns 4902 for unsupported ones
  • wallet_addEthereumChain returns success for already-supported chains per EIP-3085
  • broadcastChainChanged() correctly notifies all tabs via content script relay

Inpage Provider ✅

  • Defaults to mainnet 0x1 but immediately fetches actual chain ID on load
  • Listens for chainChanged events and updates both chainId and networkVersion properties
  • Properly updates provider state on eth_chainId responses

Edge Cases ✅

  • Price fetching correctly skipped on testnets (isTestnet check in prices.js)
  • Etherscan label checking uses dynamic explorer URL
  • balances.js uses lazy require() for state to avoid circular dependency — good pattern
  • Inpage.js 0x1 default is harmless — overwritten immediately by eth_chainId call on init

Integrity Checks ✅

  • No test modifications — zero changes to test files
  • No config changes — Makefile, Dockerfile, package.json, jest config all untouched
  • No unrelated changes — every modification directly serves Sepolia support
  • No test weakening or cheating detected
  • explorerLink() helper exported from networks.js but unused — minor, not blocking

Build ✅

  • docker build . passes (includes make check → tests, lint, formatting)
  • Branch is up to date with main — no rebase needed

Ready for merge.
