Ethereum founders published an article introducing the EIP-8141 proposal, marking a significant advancement in account abstraction technology.
PANews reported on March 1st that Ethereum co-founder vitalik.eth posted on the social media platform X, reviewing the history since the introduction of Account Abstraction (EIP-86) in early 2016 and introducing the newly released EIP-8141 proposal. This proposal is a comprehensive one aimed at addressing all the legacy issues that Account Abstraction intended to solve. It introduces the concept of "frame transactions," where a transaction can contain multiple call frames that can read each other's call data and have the ability to authorize senders and authorize gas payers. For example, a typical multi-signature account transaction can consist of a verification frame and an execution frame; if the account does not yet exist, a deployment frame can be added pre-added.
For scenarios involving gas payments using non-ETH tokens like RAI, this can be achieved through a master payment contract. The transaction frame sequence includes steps such as verification, payer verification, sending RAI to the payer, execution, and the payer refunding unused RAI and exchanging it for ETH. The entire process requires no intermediaries. Regarding privacy protocols, the master payment contract can check for valid ZK-SNARKs before paying gas, or a 2D nonce mechanism can be used to allow a single account to receive transactions from multiple users in parallel, completely eliminating the "public broadcaster" that causes poor user experiences in protocols like Railgun and PP. Regarding security, at the chain level, only transactions containing verification frames that return ACCEPT and mark the gas payment are valid. Initially, the mempool layer will use very conservative rules, with an optional more aggressive mempool; the former will gradually expand over time. Furthermore, this proposal is highly complementary to the FOCIL mechanism, ensuring that complex operations can be directly treated as first-level transactions with a fast inclusion guarantee. Vitalik stated that after more than a decade of research, these technologies are expected to be implemented within a year through a Hegota hard fork.
