@quotient-forecasting/cassie-core

The engine behind cassie: venue adapters, the strategy engine, the risk module, the encrypted keystore, the signal client, and alerting.

Most people want the CLI, not this package:

npm install --global @quotient-forecasting/cassie

Install this one to build a strategy or a runtime against the same primitives.

npm install @quotient-forecasting/cassie-core

import { Engine, createAdapter, parseBotConfig } from "@quotient-forecasting/cassie-core";

const config = parseBotConfig(JSON.parse(configJson));
const adapter = createAdapter(config.venue, { urls: config.venueUrls, creds });
const engine = new Engine({ botId: config.id, config, adapter, account, strategy, signals, alerter, state, log });

await engine.tick();

Engine.tick is idempotent: it takes a tick id derived from the interval slot and guards on a monotonic sequence in the StateStore, so a repeated slot is skipped rather than traded twice. Every order it places passes the risk module first.

Venues: Polymarket and Hyperliquid. Each adapter carries a verifiedAgainst date; SDK versions are pinned exactly, and a bump has to be re-verified against live venue docs.
