# Begin Block
At the start of each block, atomic swaps that have reached `ExpireHeight` are expired. The logic to expire atomic swaps is as follows:
```go
var expiredSwaps [][]byte
k.IterateAtomicSwapsByBlock(ctx, uint64(ctx.BlockHeight()), func(id []byte) bool {
expiredSwaps = append(expiredSwaps, id)
return false
})
// Expire incomplete swaps (claimed swaps have already been removed from byBlock index)
for _, id := range expiredSwaps {
atomicSwap, _ := k.GetAtomicSwap(ctx, id)
atomicSwap.Status = types.Expired
k.SetAtomicSwap(ctx, atomicSwap)
k.RemoveFromByBlockIndex(ctx, atomicSwap)
}
```
