@claviss/sdk

Privacy primitives for Robinhood Chain (EVM): hidden-amount shielded payments, ZK selective disclosure, stealth addresses, and a compliant privacy pool.

npm install @claviss/sdk

Modules

import { zk, stealth, pool, shielded, chain } from "@claviss/sdk";

| Module | What it does | | ---------- | ----------------------------------------------------------------------------------------------------------------------------- | | zk | Selective disclosure — prove membership or eligibility without revealing which identity (CredentialGroups). | | stealth | One-time receive addresses (secp256k1, ERC-5564 style) so a main wallet isn't exposed. | | pool | Compliant fixed-denomination privacy pool: ZK deposit/withdraw that severs the on-chain link, gated by an association set. | | shielded | Hidden-amount UTXO pool: arbitrary amounts, partial spends, change, and multi-recipient transfers, with values kept encrypted. | | chain | Robinhood Chain definitions for viem plus the contract ABIs. |

Every privacy feature keeps a disclosure and audit path — the pool is gated by an association set rather than acting as an unconditional tumbler.

Proving artifacts

The ZK modules need circuit artifacts (*.wasm and *_final.zkey) served alongside your app. The reference frontend serves them from public/; point the provers at wherever you host them.

Source

This directory is a vendored snapshot of packages/sdk from the clavis monorepo. Change it there, then re-copy src/ and rebuild with npm run build:sdk.

Requirements

ESM-only, Node 18+ or a modern browser. viem is the only chain dependency.
