Continuum Node SDK

TypeScript SDK for the Continuum node management API. It exposes typed functions for node administration, MPC groups, KeyGen, chain/token/address registries, and multi-sign (MPC) workflows. Results use a consistent SdkResult<T> shape ({ ok, data } or { ok, reason }).

Management requests can be signed with Ed25519 (local node keys, default for Node/MCP) or EIP-191 (browser wallet via a signMessage callback). The SDK builds canonical signing payloads and POST bodies; callers supply config and, for wallet flows, a signing adapter.

An optional MCP layer registers the same core functions as Model Context Protocol tools for agent use (Ed25519 only).

Install

npm install @continuumdao/continuum-node-sdk

Requires Node.js 18+.

Quick example

import {
  parseNodeSdkConfig,
  nodeId,
  createGroupRequest,
  DEFAULT_MANAGEMENT_SIGNING,
} from '@continuumdao/continuum-node-sdk';

const config = parseNodeSdkConfig({
  node: {
    baseUrl: 'https://your-node.example.com',
    managementPort: 8080,
    mpcConfigPath: '/path/on/server',
  },
  signer: { defaultKey: 'default', defaultKeyPath: null },
});

const id = await nodeId(config);
if (!id.ok) throw new Error(id.reason);

const result = await createGroupRequest(
  config,
  { nodeIds: ['...', '...'] },
  DEFAULT_MANAGEMENT_SIGNING,
);
