Build on Coalichain

Coalichain is a Polkadot SDK blockchain. Any app can record decisions, votes, trust and identity attestations on it.

ZOOZ SDK

The TypeScript SDK for Coalichain. Read decisions, sealed votes, trusts and results, verify vote receipts, and audit published results against the chain. Works in browsers and Node.js, open source (Apache-2.0).

Explorer client: stats, decisions, votes, trusts, accounts, blocks
Vote receipt verification, offline or against the chain
Result audit: rebuild the Merkle root of every published result
Live feed of finalized votes, trusts and results
Tokens and NFTs: create, send, allowlist, fixed supply, in one signature

Quick start

import { ExplorerClient } from "@zooz-protocol/sdk";

const zooz = new ExplorerClient();          // public testnet
const stats = await zooz.stats();           // blocks, votes, trusts…
const [vote] = await zooz.votes({ limit: 1 });

// Check a vote receipt from the app
const r = await zooz.verifyVote({ decision, option, salt, voter });
console.log(r.match);                       // true
