+## Loop In
+
+Performing [Loop Ins](../lightning-terminal/loop.md#loop-in), meaning to refill your channels through an onchain swap, is a cost effective way to extend the lifetime of your channel with Loop, keep it from closing.
+
+These swaps use Taproot by default, which significantly lowers the amount of data that needs to be recorded on chain. This allows Loop In to be priced as low as 1 ppm. At a fee rate of 50 sat/vB for example, a one-input-one-output transaction costs about 7200 satoshis, compared to about 8000 satoshis to close a channel, plus a minimum of 7200 to reopen it.
