MIP-5

## Abstract

Activate three EIPs from Ethereum's Fusaka upgrade ([EIP-7607](https://eips.ethereum.org/EIPS/eip-7607)): EIP-7823, EIP-7883, and EIP-7939.

## Specification

This MIP activates the following EIPs:

- [EIP-7823: Set upper bounds for MODEXP](https://eips.ethereum.org/EIPS/eip-7823)
- [EIP-7883: ModExp Gas Cost Increase](https://eips.ethereum.org/EIPS/eip-7883)
- [EIP-7939: Count leading zeros (CLZ) opcode](https://eips.ethereum.org/EIPS/eip-7939)

### Excluded EIPs

The following EIPs are already activated by Monad:

- [EIP-7951: Precompile for secp256r1 Curve Support](https://eips.ethereum.org/EIPS/eip-7951)

The following EIPs pertain to Ethereum consensus layer and data availability, so
are not relevant to Monad:

- [EIP-7594: PeerDAS - Peer Data Availability Sampling](https://eips.ethereum.org/EIPS/eip-7594)
- [EIP-7917: Deterministic proposer lookahead](https://eips.ethereum.org/EIPS/eip-7917)
- [EIP-7918: Blob base fee bounded by execution cost](https://eips.ethereum.org/EIPS/eip-7918)

The following EIPs set parameters for which Monad makes different choices per [the Monad specification](../assets/MIP-4/monad-initial-spec-proposal.pdf) (30M
transaction gas limit, and 2MB block size), so are not included:

- [EIP-7825: Transaction Gas Limit Cap](https://eips.ethereum.org/EIPS/eip-7825)
- [EIP-7934: RLP Execution Block Size Limit](https://eips.ethereum.org/EIPS/eip-7934)

## Rationale

Deferred to the individual EIPs included.

## Security Considerations

Deferred to the individual EIPs included.
