@deepbookie/node

The Node-only signing layer for DeepBookie — it takes the unsigned transactions built by @deepbookie/core and signs + executes them with a local key. Used by @deepbookie/mcp and @deepbookie/cli.

This is the edge in "sign at the edge": the agent/registry never holds a key — this package does, on the machine the operator controls.

Install

pnpm add @deepbookie/node @mysten/sui

What's inside

• getOrCreateKeypair() — resolves a signer in order: DEEPBOOKIE_PRIVATE_KEY (a suiprivkey… secret) → ~/.deepbookie/config.json (persisted, mode 0600) → auto-generate, persist, and warn you to fund the new address.
• signAndExecute(client, keypair, tx) — sign an unsigned Transaction, execute it, wait for finality, return the result (digest + effects).
• logger — a Pino logger (writes to stderr, so it never corrupts an MCP stdio JSON-RPC channel).

Example

import { getOrCreateKeypair, signAndExecute } from '@deepbookie/node';
import { allTools, getToolsForAdapter, createContext } from '@deepbookie/core';

const kp = getOrCreateKeypair();
const ctx = createContext({ network: 'testnet', sender: kp.toSuiAddress() });
const api = getToolsForAdapter(allTools, ctx);

const unsignedTx = await api.build('mint', { oracleId: '0x…', strikeUsd: 63000, direction: 'UP', quantityUsd: 5 });
const res = await signAndExecute(ctx.client, kp, unsignedTx); // your key signs — never the agent
console.log(res.digest);

Runs on Sui testnet by default (DEEPBOOKIE_NETWORK).
