## EIP-4844 Transactions
[EIP-4844](https://eips.ethereum.org/EIPS/eip-4844) transactions (type `0x3`) was introduced in Ethereum's Dencun fork. This provides a temporary but significant scaling relief for rollups by allowing them to initially scale to 0.375 MB per slot, with a separate fee market allowing fees to be very low while usage of this system is limited.
[EIP-4844](https://eips.ethereum.org/EIPS/eip-4844) transactions (type `0x3`) were introduced in Ethereum's Dencun fork. This provides a temporary but significant scaling relief for rollups by allowing them to initially scale to 0.375 MB per slot, with a separate fee market allowing fees to be very low while usage of this system is limited.
Alongside the legacy parameters & parameters from EIP-1559, the EIP-4844 transactions include:
- `max_fee_per_blob_gas`, The maximum total fee per gas the sender is willing to pay for blob gas in wei
- `blob_versioned_hashes`, List of versioned blob hashes associated with the transaction's EIP-4844 data blobs.
The actual blob fee is deducted from the sender balance before transaction execution and burned, and is not refunded in case of transaction failure.
## EIP-7702 Transactions
[EIP-7702](https://eips.ethereum.org/EIPS/eip-7702) transactions (type `0x4`) were introduced in Ethereum's Pectra fork. This provides the ability for a wallet to delegate its execution to an authorized smart contract. Alongside the fields present from the EIP-1559 transaction type, EIP-7702 transactions include:
- `authorization_list`
- `signature_y_parity`
- `signature_r`
- `signature_s`
where `authorization_list` is a list of authorizations, which are tuples containing the following fields:
- `chain_id`
- `address`
- `nonce`
- `y_parity`
- `r`
- `s`
