# eth\_sendBlobs

```javascript
{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "eth_sendBlobs”,
  "params": [
    {
      txs,            // Array[String], A list of blob transactions. One transaction per blob permutation.
      maxBlockNumber, // (Optional) String, a hex-encoded string representing the block number of the last block in which the transactions should be included.
    }
}
```

### Background

Blob pools currently present a challenge to external blob originators, as they function somewhat like a black box. Typically, only a single transaction can be sent, necessitating a guess on the number of blobs to include. Here is an example of where this could be problematic:

*Originator A sends a transaction with 6 blobs, but there is a higher paying transaction with 1 blob already in the mempool. Due to the 6-blob per block limit, no blobs from Originator A will be posted.*

### Functionality

The `eth_sendBlobs` endpoint enables the sending of all permutations of blob transactions from a single sender. This is made possible because these blob transactions enter a custom blob pool that allows for multiple transactions with the same nonce. These blobs are then sorted individually to generate the optimal combination and added to our blocks.

## **Example**

If you have 6 blobs to post, you would send a transaction from the same sender with the same nonce containing different permutations of blobs. This means you would end up sending up to 6 transactions, each containing a different number of blobs:

```js
curl -s --data '{
  "jsonrpc": "2.0",
  "id": "1",
  "method": "eth_sendBlobs",
  "params": [{
    "txs": [
      "0x12...ab1",  // Transaction with 1 blob
      "0x34...cd2",  // Transaction with 2 blobs
      "0x56...ef3",  // Transaction with 3 blobs
      "0x78...gh4",  // Transaction with 4 blobs
      "0x9a...ij5",  // Transaction with 5 blobs
      "0xbc...kl6"   // Transaction with 6 blobs
    ]
  }]
}' -H "Content-Type: application/json" -X POST https://rpc.titanbuilder.xyz
```

## ‍**Response example**

```js
{"result":200,"error":null,"id":1}‍
