Race Condition in Freebet Selection When Switching Chains

[utgarda]

Problem

When selecting a freebet that requires a chain switch, there's a race condition where the freebet and token are set immediately while the chain switch is still pending. This causes a brief inconsistent state where:

• The selected freebet is from Chain B
• The app is still on Chain A
• The token displayed may be incorrect

Steps to Reproduce

1. Connect wallet on Chain A (e.g., Polygon)
2. Have freebets available on both Chain A and Chain B (e.g., Base)
3. Select a freebet from Chain B
4. Observe that the freebet/token are set before the chain actually switches

Expected Behavior

• Chain should switch first
• Only after successful chain switch should the freebet and token be selected
• No intermediate inconsistent state should be visible

Current Behavior

• Freebet and token are set immediately
• Chain switch happens asynchronously afterward
• Brief period where selected freebet doesn't match current chain

Impact

• Confusing UX during chain switches
• Potential for incorrect token display
• May cause issues with bet placement if user acts during the inconsistent state
