Session key management and paymaster interaction protocol for Starknet smart accounts. Defines ISessionKeyManager interface, session signature format, validation algorithm, admin selector blocklist, paymaster interaction protocol, and optional spending policy extension.

Session keys are the missing piece between smart accounts and real usage. Without them, every on-chain action requires a wallet popup, a manual signature, and gas awareness. That kills gaming, DeFi automation, subscriptions, and especially AI agents that need to act autonomously within defined boundaries.
This SNIP proposes the interface that makes all of that work across wallets and paymasters with zero custom integration.
What this SNIP defines
ISessionKeyManagertrait andSessionDatastruct for on-chain session key management[session_pubkey, r, s, valid_until]What this unlocks
For AI agents: scoped, time-bounded, call-limited on-chain authority. An agent can trade, rebalance, or execute strategies using only the selectors and tokens you allow, with spending caps and automatic expiry. No custody, no owner key exposure, instant revocation.
For dApps: build session key support once and it works with every compliant wallet and every compliant paymaster. No more integrating separately with each wallet team.
For paymasters: sponsor session transactions from any compliant account using the same signature format and discovery protocol.
For Starknet: the account abstraction advantage only matters if applications can actually delegate execution safely. This is the coordination layer that turns smart accounts into a platform.
Reference implementation
