Guides & Tutorials on Ethereum, Account Abstraction & Blockchain by Mislav Javor
A comprehensive overview of native account abstraction proposals in Q1 2026, comparing Vitalik's EIP-7701, Tempo transactions, and EIP-8130—their approaches to validation, gas sponsorship, and the tradeoffs between generality and speed of shipping.
A novel technique that brings Smart Account features like batch and cross-chain execution to all EOA users through a single signature, without requiring EIP-7702 upgrades or fund migration.
Verifiable EVM scripting allows developers to write complex DeFi flows in TypeScript that execute on smart accounts, eliminating the need for custom contract deployments and enabling multichain execution with a single signature.

Despite years of progress in Ethereum tooling, building user-friendly dApps still feels difficult. Verifiable scripting represents a shift in how smart accounts, transaction flows, and user interactions are designed—enabling dynamic, conditional, and composable execution scripts that span multiple chains.

EIP-7702 allows EOAs to delegate their execution to smart contracts, giving them programmable capabilities without requiring users to migrate to new wallets.

EIP-7702 enabled developers to cheaply deploy new Smart Accounts. Those accounts came with limitations when deploying across multiple chains or when trying to use resource locks or multi-sig setups. The PREP method solves that issue.

A comprehensive technical deep dive into the PREP method - combining Nick's method with EIP-7702 to create smart accounts that provably have no associated private key.
A novel P2P network standard enabling guaranteed conditional execution of transactions across one or more independent blockchains with a single off-chain signature.
