Prague is the name of the fork on the execution client side, and Electra is the upgrade name on the consensus layer client side. -There are 3 main features along with some smaller EIPs included in Pectra.

They are: [EIP-7251](https://eips.ethereum.org/EIPS/eip-7251) also known as Max effective balance (MaxEB), [EIP-7702](https://eips.ethereum.org/EIPS/eip-7702), and [EIP-7002](https://eips.ethereum.org/EIPS/eip-7002) also known as Execution Layer triggered exits. -The MaxEB feature will allow the user to have a > 32ETH effective balance.

Users/Devs --- **FAQ**: -#### **Q:** What is EIP-7702/Account abstraction? -While EIP-7702 isn’t quite account abstraction, it does provide execution abstraction, i.e adds additional functionality to externally owned accounts (EOAs. This allows your EOA to do things like send transaction batches and delegate to other cryptographic key schemes, like passkeys. It does this by setting the code associated with the EOA to a protocol-level proxy designation. A full specification can be found [here](https://eips.ethereum.org/EIPS/eip-7702). It introduces a new transaction type that temporarily authorizes specific contract code for an EOA during a single transaction, allowing EOAs to function as smart contract accounts. This enables several use cases for users, including transaction batching, gas sponsorship, and privilege de-escalation. +#### **Q:** What is EIP-7702 and how does it relate to Account abstraction? +While [EIP-7702](https://eips.ethereum.org/EIPS/eip-7702) isn’t quite account abstraction, it does provide execution abstraction, i.e adds additional functionality to externally owned accounts (EOAs.

How can I use it as a wallet dev? -The specification for EIP-7702 is can be found [here](https://eips.ethereum.org/EIPS/eip-7702). To get started as a wallet developer, you'll need to determine a smart contract wallet core to use with the EOA. Pay close attention to how the wallets [should be initialized](https://eips.ethereum.org/EIPS/eip-7702#front-running-initialization).

As a smart contract developer, you should know that after Prague the majority of users on Ethereum will now be able to interact with the chain in more complex ways than were feasible before. Many standards have been developed to work around the limitations of EOAs, such as [ERC-2612 Permit](https://eips.ethereum.org/EIPS/eip-2612). -#### **Q:** What do I need to know as a security engineer/auditor? +#### **Q:** What do I need to know about EIP-7702 as a security engineer/auditor? As a security engineer / auditor, you must be aware that the previous assumption that a frame cannot be reentered when `msg.sender == tx.origin` no longer holds.

Before MaxEB, any entity that wanted to contribute a large amount of ETH to consensus had to spin up multiple validators because each was capped at a maximum of 32 ETH. EIP-7251 will allow large stake operators to consolidate their ETH into fewer validators, using the same stake with up to 64 times less individual validators. It also allows solo stakers' ETH to be compounded into their existing validator and contribute to their rewards without having to use the exact validator amount. For example, 35 ETH will be considered the validator's effective balance by the protocol, instead of leaving out 3 ETH ineffective and waiting till 64 ETH for 2 validators.

To consolidate your validators, you first need to ensure that both the source and target validators have either `0x01` or `0x02` credentials assigned.
