Summary: CAIP-312 is best understood as the session-state read primitive in the CAIP-25 wallet-session stack rather than as a convenience RPC. Its core move is to let a caller retrieve the current authorizations and properties of an active wallet session at any time, including flows where the wallet, not the dapp, remains the durable source of truth because no sessionId is being tracked externally. That makes it a useful comparison class for CAIP-25, CAIP-285, and CAIP-316: those define session creation, revocation, and lifecycle guidance, while CAIP-312 standardizes how a caller can rehydrate the current authorization state without inventing wallet-specific bookkeeping.
What it does:
Defines a wallet_getSession JSON-RPC method for retrieving the current authorizations of an active CAIP-25 session
Supports both explicit sessionId queries and no-sessionId flows where a single internally tracked session can be fetched directly
Returns session scopes and properties so the caller can inspect what methods, notifications, and accounts remain authorized
Recommends generic failure behavior in ambiguous or untrusted cases to reduce fingerprinting and analytics leakage
Lets dapps recover current state after reconnects, missed events, or wallet-side changes rather than assuming locally cached permissions remain accurate
Complements wallet_sessionChanged notifications by providing a canonical pull-based way to resynchronize session state
Key claims:
The most important design move is shifting session truth toward a queryable wallet-managed state rather than forcing every caller to persist the full authorization object forever. That is a real architectural choice, not just a nicer developer experience.
CAIP-312 matters because it makes long-lived authorization legible after the initial connect flow. In practice, this is where many wallet integrations get blurry: everyone can request permissions, but not every stack cleanly exposes what is currently granted.
The draft’s ambiguity rules are analytically important. If no sessionId is supplied and only identifier-based sessions exist, the method fails instead of guessing, which keeps transport assumptions explicit rather than quietly collapsing multiple sessions into one inferred state.
As with CAIP-285, the spec recommends generic error behavior for unknown counterparties, reminding us that session-state introspection is also a privacy surface.
CAIP-312 is useful in this corpus because it helps unbundle wallet authority into separate verbs: create a session, query what survived, receive updates when it changes, and revoke it when the relationship should end.
The best comparison frame is not “another connect-wallet method”; it is “the pull-based state reconciliation layer that makes CAIP-25 sessions auditable and recoverable across transports.”
Whitepaper: No standalone CAIP-312 whitepaper or litepaper surfaced in this pass. The clearest primary materials were the official draft text, the raw markdown in the CAIPs repository, and the linked lifecycle-method proposal thread alongside CAIP-25 / CAIP-316 context; see ../../whitepapers/caip-312-primary-sources-2026-05-10.md.
Keep it on the pull-based session-state read path after connect. It is not the revoke method, not the invocation envelope, and not a general wallet-session directory.
