Exchange Tab - white or black Tradingview chart

**Describe the bug**
White or black Tradingview chart in the Exchange Tab.

**To Reproduce**
Steps to reproduce the behavior:
1. Go to Exchange by clicking on the Exchange Tab
2. See error

**Expected behavior**
Tradingview chart to load every time without failure, white, or black screen and regardless of which browser or device utilized.
After dev fixes yesterday, I tested with both Opera and Firefox; both browsers were working perfectly. Prior to that, with Opera browser, Tradingview screen was black. Today, no chart with Opera and field is white instead of black this time.
Firefox loaded fine, but with errors (captured and enclosed)

**Screenshots**
Late yesterday after dev fixes, everything was working extremely well
Today - White screen instead of black; Before dev fixes, screen was black

Start at the Exchange Tab's TradingView chart integration and reproduce the white or black chart in Opera and Firefox using the reported browser versions. Use the Opera and Firefox logs, especially the null-property, BindToChainState, and missing currentAccount errors, to trace the failure; done means the chart loads reliably across the reported browsers and devices.
