near-hydra-core

Core library for near-hydra — the unified CLI + MCP server for NEAR's chain-abstraction stack.

This package wires together NEAR's primitives (accounts, contract calls, FTs) with cross-chain MPC signing (chainsig.js) and NEAR Intents (@defuse-protocol/one-click-sdk-typescript) behind a single, agent-ergonomic API. It's the engine; you almost certainly want one of the consumer packages instead:

• near-hydra — CLI
• near-hydra-mcp — MCP server for Claude Code, Cursor, etc.

Install (library use)

npm install near-hydra-core

Quick example

import { loadConfig, deriveAddress, viewAccount } from "near-hydra-core";

const cfg = loadConfig(); // env-driven by default
const acct = await viewAccount(cfg, "near");
const btc = await deriveAddress(cfg, "bitcoin", "near", "bitcoin-1");
console.log(btc.address); // bc1qshk...

Notes

• A postinstall script idempotently patches a known chainsig.js v1.1.14 ESM packaging bug. Safe to run multiple times.
• Signing operations require policy.readOnly = false and a configured NEAR signer. See https://github.com/nikshepsvn/near-hydra/blob/main/SECURITY.md.
