Smart Account Risk

Overview

Smart accounts replace or extend simple key-controlled accounts with contract-based authorization. Features may include multisignature, session keys, spending limits, social recovery, batched actions, sponsored fees, and custom validation.

Programmability creates new failure modes such as flawed modules, unsafe upgrades, malicious paymasters, replay, signature ambiguity, recovery abuse, storage collisions, and dependency compromise. Users may not understand the authority granted to plugins or session credentials.

Implementers should minimize trusted modules, audit authorization paths, bind signatures to exact intent, restrict upgrades, monitor changes, and support safe revocation. Recovery, relayer failure, chain changes, and unavailable infrastructure should be tested before accounts hold material value. Wallet interfaces should make module authority and lasting permissions understandable before approval.

Communication about Smart Account Risk should separate confirmed facts, working hypotheses, assumptions, unknowns, and decisions.

For Smart Account Risk, production scope should name the relevant keys, signing policies, accounts, addresses, transactions, recovery paths, and custody boundaries, the decision being supported, the accountable owner, and the time and jurisdiction boundaries.

Smart account risk is exposure created by programmable account logic, modules, signers, relayers, recovery paths, and upgrade authority. Smart accounts improve control flexibility but expand the authorization surface across code, modules, upgrades, recovery, relayers, and user understanding.

For Smart Account Risk, the assessment should evaluate exposure created by programmable account logic, modules, signers, relayers, recovery paths, and upgrade authority. The assessment record should separate observed evidence supporting exposure created by programmable account logic, modules, signers, relayers, recovery paths, and upgrade authority from assumptions, state the time horizon and existing controls, and identify who owns any remaining exposure. Monitoring should test whether the conditions described in exposure created by programmable account logic, modules, signers, relayers, recovery paths, and upgrade authority have changed enough to require a new rating, treatment, or approval.
