# Begin Block
At the start of each block, atomic swaps that meet certain criteria are expired or deleted.

```go
func BeginBlocker(ctx sdk.Context, k Keeper) {
k.UpdateExpiredAtomicSwaps(ctx)
k.DeleteClosedAtomicSwapsFromLongtermStorage(ctx)
}
```
## Expiration
If an atomic swap's `ExpireHeight` is greater than the current block height, it will be expired. The logic to expire atomic swaps is as follows:
```go
var expiredSwapIDs []string

}
// Expire the uncompleted swap and update both indexes

## Deletion
Atomic swaps are deleted 86400 blocks (one week, assuming a block time of 7 seconds) after being completed. The logic to delete atomic swaps is as follows:
```go
k.IterateAtomicSwapsLongtermStorage(ctx, uint64(ctx.BlockHeight()), func(id []byte) bool {
swap, found := k.GetAtomicSwap(ctx, id)
if !found {
return false
