@slicekit/id-primitives

The protocol layer of Slice ID: portable building blocks shared by @slicekit/id, Slice's ID registry, and the Slice API.

This package is not primarily designed for public consumption. It is published as a separate package because @slicekit/id and Slice's server-side verifiers need a single source of truth for delegation encoding and verification. Applications integrating Slice ID should depend on @slicekit/id, which builds on these primitives.

Installation

npm install @slicekit/id-primitives viem

The package depends on @slicekit/erc8128, Wallet's runtime-neutral protocol subpaths, and viem. Browser sign-in, React, wagmi, and Next.js integrations live in @slicekit/id.

Entry Points

• @slicekit/id-primitives — delegation contracts: permission and audience normalization, delegation chain parsing, posture components, revocation values, budget validation.
• @slicekit/id-primitives/server — request verifier, authorization caches, session records, sealed cookies, session lifecycle and middleware (Workers / Node runtimes; a browser build throws on import).
• @slicekit/id-primitives/types — server-safe Slice ID types.
