+Basic flows
+1. User swap threshold + x legacy, then swap x new back to legacy
+2. User swap and fail (not enough balance), then contract gets more new tokens from reverse swap, swap again and succeed.
+3. end to end: swaps, send to L1, swap and fail, get money, swap and aucceed
+4. reverse swap and fail, gets money, reverse swap and succeed
+5. swap without approve fail, swap without balance fail, then approve then swap
+6. User just transfer money, then swap
+7. user swap twice 
+
+Send to L1
+1. A small swap triggers the threshold
+2. Remainder after threshold
+3. More than one send to l1 in one tx
+4. Sends not above the MAX
+5. Sends all legacy to L1 (function), then swap should fail
+
+Set threshold
+1. send to L1 after decrease threshold
+2. not send to L1 in set threshold if not needed
+3. start with the large batch size, then change to the small batch size, check send to L1
+
+Approve to owner
+1. Withdraw all/part of legacy/new
+
+Upgrade
+1. some swaps, send to L1, upgrade, cant swap/do anything
