@dcprotocol/core

@dcprotocol/core

Core primitives for DCP runtimes.

Most developers should use @dcprotocol/vault, @dcprotocol/agent, or @dcprotocol/client first. Use core when you are extending DCP itself or building a runtime that needs the same primitives as the vault.

Install

npm install @dcprotocol/core

What Is Inside

crypto      encryption, signatures, canonical JSON
wallet      key custody (create/encrypt/sign) + RE-EXPORTS the pure wallet logic
            (tx build/validate/runner) from @dcprotocol/wallet-core
storage     SQLite vault storage and audit data
budget      budget and policy helpers
pairing     signed pairing grants and remote-agent invites
types       shared TypeScript types (VaultError is re-exported from wallet-core)

Relationship to @dcprotocol/wallet-core

The pure, dependency-light wallet logic — transaction building, validation, the execution runner, token registry, Jupiter, and the shared VaultError — lives in @dcprotocol/wallet-core (no native deps, React-Native-safe). core adds key custody, storage, and crypto (which need native modules) on top, and re-exports wallet-core for backward compatibility. Import wallet primitives from either; they are the same code.

Boundaries

Core provides building blocks. The vault decides policy, approval, signing, and storage behavior in the running product.
