I'm not sure this will work as expected because it only reloads the bridgechain list after submitting the transaction (unless I misunderstood). The problem is that the transaction isn't forged instantly. I think it's best to have a timer on that bridgechain list to keep refreshing the list every minute or so to check for changes

@alexbarnsley what do you think: 21ec4f2#diff-cebae3f54745803997fc366f1bb91e3b ?

I partly think the fetchBridgechains method shouldn't clear the screen while loading. It looks weird because of the flicker where the data clears and re-appears 🤔
