# Blobs.toCellProofs

Compute the flat list of PeerDAS (EIP-7594) cell KZG proofs for a list of [`Blobs.Blobs`](/api/Blobs/types#blobs). Returns `128 * blobs.length` proofs, where `proofs[i * 128 + j]` is the proof for cell `j` of `blobs[i]`'s extended form.

## Imports

:::code-group
```ts [Named]
import { Blobs } from 'ox'
```

```ts [Entrypoint]
import * as Blobs from 'ox/Blobs'
```
:::

## Examples

```ts twoslash
// @noErrors
import { Blobs } from 'ox'
import { kzg } from './kzg'

const blobs = Blobs.from('0xdeadbeef')
const cellProofs = Blobs.toCellProofs(blobs, { kzg }) // [!code focus]
```

### Configuring Return Type

It is possible to configure the return type with the `as` option.

```ts twoslash
// @noErrors
import { Blobs } from 'ox'
import { kzg } from './kzg'

const blobs = Blobs.from('0xdeadbeef')
const cellProofs = Blobs.toCellProofs(blobs, {
  as: 'Bytes', // [!code focus]
  kzg
})
// @log: [Uint8Array [ ... ], Uint8Array [ ... ], ...]
```

## Definition

```ts
function toCellProofs<blobs, as>(
  blobs: blobs | Blobs<Bytes.Bytes> | Blobs<Hex.Hex>,
  options: toCellProofs.Options<as>,
): toCellProofs.ReturnType<as>
```
