Parameters

Required

| Short Name | Full Name | description |
|------------|--------------|------------------| | -r | --rpc | provider url | | -p | --privateKey | private key | | -f | --file | upload file path | | -t | --to | to address |

Optional

| Short Name | Full Name | description |
|------------|-------------|-------------------------------------------------------------------------------------------------------------------------------------| | -d | --data | Calldata for contract calls | | -v | --value | The amount of ETH that will be sent per transaction. If a file has multiple transactions, the total ETH amount is "value * txCount" | | -c | --count | The number of blobs attached to the transaction | | -n | --nonce | Transaction nonce | | -g | --gasPrice | Transaction gas price | | -b | --blobPrice | Blob gas price |

Command

eth-blob-uploader -r <rpc> -p <private-key> -f <file-path> -t <to-address>

// If you are calling a contract function, you need to bring calldata
eth-blob-uploader -r <rpc> -p <private-key> -f <file-path> -t <to-address> -d [calldata]

// You can set the eth that will be sent with each transaction via -v
eth-blob-uploader -r <rpc> -p <private-key> -f <file-path> -t <to-address> -v [value]

// You can specify the number of blobs uploaded in one transaction
eth-blob-uploader -r <rpc> -p <private-key> -f <file-path> -t <to-address> -c [count]

// output: send hash 

Note: A file may contain n blobs and there will be n/3 transactions, so -v should not be the total ETH, but the number of each transaction.
