@hashpower/oracle-abi

ABIs and deployment addresses for the Hashpower hashprice oracle contracts on Base.

Both oracles implement Chainlink's AggregatorV3Interface — read the live price with latestRoundData():

| Contract | answer meaning | Decimals | | --- | --- | --- | | HashpriceUSD | 100 TH/s/day in USD | 8 | | HashpriceBTC | 100 TH/s/day in satoshis | 8 |

Usage

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

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

const [, answer] = await client.readContract({
  address: contracts.HashpriceUSD,
  abi: HashpriceUSDAbi,
  functionName: "latestRoundData",
});

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

Historical data

Query the oracles subgraph (URLs in deployments.json under environments.<env>.subgraphs.oracles) for hashprice history and candles.

How this package is built

Contents are generated — do not edit by hand:

• src/ is copied from ../contracts/abi (the Hardhat codegen output, drift-checked in CI) 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 from CI (see .github/workflows/publish-oracle-abi.yml). A dev publish updates environments.testnet and is tagged dev (minor bump). A main publish updates environments.mainnet and is tagged latest; the first mainnet cut is 3.0.0, skipping any major npm has already used.
