@hashpower/futures-abi

ABIs and deployment addresses for the Hashpower hashprice futures marketplace on Base.

HashPowerFutures is an on-chain order book for dated hashprice futures with physical/cash delivery:

| Action | Function | | --- | --- | | Place an order | createOrder(price, deliveryDate, destURL, qty) — signed qty: + buy, − sell | | Batch place | createOrders(OrderIntent[]) | | Cancel a resting order | closeOrder(orderId) | | Read the book | getBidPrices, getAskPrices, getQuantityAtPrice, getMarketPrice | | Margin / PnL | getFuturesOrderMargin, getFuturesUnrealizedPnl (liquidatability lives on the portfolio margin engine: isLiquidatable) | | Delivery | depositDeliveryPayment, withdrawDeliveryPayment, closeDelivery |

Collateral flows through the shared CollateralVault (see @hashpower/collateral-abi) — deposit USDC there before trading.

Usage

import { HashPowerFuturesAbi } from "@hashpower/futures-abi";
import deployments from "@hashpower/futures-abi/deployments.json" with { type: "json" };

// "testnet" (Base Sepolia) or "mainnet" (Base)
const env = process.env.HASHPOWER_ENV ?? "testnet";
const { contracts, subgraphs } = deployments.environments[env];

const marketPrice = await client.readContract({
  address: contracts.HashPowerFutures,
  abi: HashPowerFuturesAbi,
  functionName: "getMarketPrice",
});

Order books, positions, fills, and liquidations are indexed by the futures subgraph (subgraphs.futures in deployments.json).

Raw JSON ABIs (for subgraphs and non-TypeScript consumers) are available under @hashpower/futures-abi/json/<Contract>.json.

How this package is built

Contents are generated — do not edit by hand:

• src/ is copied from ../contracts/abi (the Hardhat codegen output, mocks excluded) by scripts/build.mjs, then compiled to dist/.
• deployments.json is the canonical address manifest for this repo; it is updated when contracts are (re)deployed.

Publishing happens automatically from CI when ABIs or the manifest change (see .github/workflows/publish-futures-abi.yml).
