RIP-7711

Defines the mempool protocol for native account abstraction transactions.

RIP-7711 specifies how mempools should handle native account abstraction transactions introduced by RIP-7560. This ensures that L1 and L2 clients consistently propagate, validate, and prioritize native AA transactions.

🧠 Motivation

ERC-4337 transactions use a separate UserOp mempool, which limits compatibility with Ethereum’s native infrastructure. With RIP-7560 proposing native AA transaction types, RIP-7711 provides the protocol rules for:

  • Propagation across peers
  • Validation and simulation requirements
  • Ordering and mempool eviction

🧩 Core Elements

Transaction Type Support

Clients must support a dedicated transaction type for native AA. The payload structure is defined in RIP-7560.

Validation Semantics

Clients must:

  • Call validateTransaction() on the contract sender
  • Simulate transactions prior to inclusion (clients may defer simulation until mempool admission)
  • Ensure gas cost accounting and rejection rules are upheld

Ordering Rules

  • Native AA txs must be ordered based on fee priority, similar to regular txs
  • Transactions from the same sender must respect nonce ordering (if applicable)

P2P Protocol Handling

  • Nodes must propagate native AA txs using devp2p, with support for typed transactions (EIP-2718)
  • New tx type IDs or version tags may be used to distinguish native AA txs

🔐 Security & Anti-DoS

  • Nodes must cap validation gas
  • Misbehaving txs (e.g. failing validation) should be dropped early
  • Clients may maintain local reputation scores to throttle spam
  • Clients should apply gas caps to validation to prevent griefing
  • Failed validations should return clear diagnostics (e.g., FailedOp analogs)

🔄 Compatibility

  • Works with RIP-7560’s native tx type
  • Can coexist with ERC-4337 infrastructure
  • Encourages unification of tx handling across L1 and L2 networks

✅ Summary

RIP-7711 provides the mempool-level coordination required to support native AA transactions introduced by RIP-7560. It standardizes propagation, simulation, and ordering rules to ensure a coherent experience across Ethereum clients and rollups.
