# dETH Isolation and savETH Isolation
Either dETH or savETH can be used to isolate a KNOT. If the KNOT doesn't have sufficient dETH, it's savETH can be used for the isolation.

## dETH Isolation
`dETHRequiredForIsolation`: This function is used to calculate the dETH required for a KNOT's isolation.
The input parameter required is `blsPublicKey`.
```
await sdk.utils.dETHRequiredForIsolation(blsPublicKey);
```
It returns the dETH amount in BigNumbers.

## savETH Isolation
`savETHRequiredForIsolation`: this function is used to calculate the amount of savETH required for the KNOT's isolation.
The input parameter required is `blsPublicKey`.
```
await sdk.utils.savETHRequiredForIsolation(blsPublicKey);
```
It returns the savETH amount in BigNumbers.
