Abstract
Activate six EIPs from Ethereum’s Glamsterdam upgrade (EIP-7773): EIP-7708, EIP-7843, EIP-7981, EIP-7997, EIP-8024 and EIP-8246.
Specification
This MIP activates the following EIPs:
- EIP-7708 — ETH transfers emit a log
- EIP-7843 — SLOTNUM opcode
- EIP-7981 — Increase Access List Cost (modified, see below)
- EIP-7997 — Deterministic Factory Contract
- EIP-8024 — Backward compatible SWAPN, DUPN, EXCHANGE
- EIP-8246 — Remove SELFDESTRUCT Burn
EIP-7981 is adopted with access_list_data_cost = 40 * access_list_bytes
(800 gas per address and 1280 gas per storage key) rather than 64 gas per byte.
All other EIPs included in Glamsterdam (EIP-7773) are not activated; see Rationale.
Chain Specifics
EIP-7997 has no effect on Monad Mainnet or Testnet: the deterministic factory contract has already been deployed on those networks via the usual keyless transaction method. Adopting the EIP therefore only affects local development networks.
Rationale
Block-level access lists are incompatible with Monad’s asynchronous execution model. Proposers do not execute blocks, and so cannot reliably populate the access lists. EIP-7928 is therefore not adopted by Monad:
- EIP-7928 — Block-Level Access Lists
The following EIPs deal with the Ethereum consensus layer and are therefore not adopted by Monad:
- EIP-8045 — Exclude slashed validators from proposing
- EIP-8061 — Increase exit and consolidation churn
- EIP-8282 — Builder Execution Requests
- EIP-7688 — Forward compatible consensus data structures
- EIP-7732 — Enshrined Proposer-Builder Separation
The following EIPs establish a new two-dimensional gas model for Ethereum. Monad may make different choices regarding gas metering in the future, and so at this time the protocol will not adopt the Ethereum changes in these EIPs:
- EIP-2780 — Resource-based intrinsic transaction gas
- EIP-7778 — Block Gas Accounting without Refunds
- EIP-7976 — Increase Calldata Floor Cost
- EIP-8037 — State Creation Gas Cost Increase
- EIP-8038 — State-access gas cost update
Since EIP-7976 is not adopted, the access list data cost in EIP-7981 is set to match Monad’s existing calldata floor cost of 40 gas per byte, rather than the increased Ethereum floor of 64.
On Monad, the maximum contract size is already 128KB. The increase in EIP-7954 is therefore not adopted:
- EIP-7954 — Increase Maximum Contract Size
The networking EIPs in EIP-7773 concern Ethereum’s devp2p protocols, which Monad does not use, and its informational EIPs specify no protocol changes; neither group is adopted.
Backwards Compatibility
No backwards compatibility issues beyond those in the original EIP specifications.
Security Considerations
No security considerations beyond those in the original EIP specifications.
