Add ERC: Generic Relayer Architecture for Smart Accounts

[seansing]

Adds a new draft ERC: Generic Relayer Architecture for Smart Accounts

Summary

This proposal introduces a standardized off-chain relayer architecture for smart accounts, enabling gasless and token-based fee transactions via a consistent set of JSON-RPC methods.

It defines a relayer_* RPC namespace that complements existing wallet standards, covering fee discovery, transaction submission (including multichain), capability discovery, and status tracking.

Motivation

As smart account adoption grows (e.g. via EIP-4337 and EIP-7702), relayers have become a critical component of the execution flow. However, current relayer implementations are fragmented, with inconsistent APIs, fee models, and integration patterns.

This proposal aims to standardize relayer interactions to:

• Reduce integration complexity for wallets and dApps
• Improve interoperability across relayer providers
• Provide a consistent developer experience for gasless and sponsored transactions

Specification Overview

The ERC introduces five new JSON-RPC methods:

• relayer_getFeeData
• relayer_sendTransaction
• relayer_sendTransactionMultichain
• relayer_getCapabilities
• relayer_getStatus

It also defines:

• A standardized transaction lifecycle for relayed execution
• Payment abstraction (token-based or sponsored)
• Task-based transaction tracking
• Error codes and optional authentication patterns

Notes for Reviewers

• This proposal is fully off-chain and does not require protocol changes
• Designed to be compatible with any smart account implementation
• Builds on patterns introduced in EIP-5792 while extending the execution path to relayers
