Problem

Customer reports external chain assets (ETH/BSC) not showing in the wallet.

Investigation revealed that the EVM asset service silently swallows errors:

} catch {
  return { amount: Amount.fromRaw('0', ...), symbol: ... }
}

This makes debugging impossible - we don't know if the RPC failed, returned an error, or what went wrong.

Changes

• Add console.error logging when balance queries fail (includes chain, address, RPC URL)
• Add console.debug logging in DEV mode to trace query execution
• No behavior change - still returns 0 balance on error, but now we can see why

Testing

• pnpm turbo run lint:run typecheck:run - passes
• pnpm turbo run test:run - all 69+ tests pass

Next Steps

After merging, customer can:

1. Open browser DevTools console
2. Try to view their wallet
3. Share any error logs so we can diagnose the actual issue
