Turnkey ExtensionsOne wallet. Every chain. One API.

Cross-chain signing, balances, swaps, perps and prediction markets over a Turnkey wallet — as a typed SDK and as a CLI.

A product API, not a toolbox

createSwarm({ identity }) gives you wallet, markets, portfolio, perps, signals and risk — named after what you want to do, not after the protocol underneath.

Read the SDK reference

Nothing signs by accident

Every operation defaults to mode "plan", returns the same shape whether it previewed or executed, and passes a spend cap plus standing limits before it reaches the key.

The execution contract

The same thing at the terminal

The swarm binary drives the same library headlessly — dry-run by default, budget-gated, JSON on demand, and servable to an agent over MCP.

Browse the commands

Building blocks still first-class

EVM, Bitcoin, Solana, TRON, TON, Sui, NEAR, Hyperliquid, Polymarket, ADI, CoW, 0G Compute — every subpath export documented, for when the product API does not wrap what you need.

Two entry points

import {
  createSwarm,
  markets,
} from "@swarm-ai-labs/turnkey-extensions/runtime";

// Public market data — no wallet involved.
await markets.perps({ search: "ETH" });
await markets.funding({ minApr: 0.2 });

// Everything else, bound to one wallet and one budget.
const swarm = createSwarm({ identity, policy: { capUsd: 500 } });

await swarm.portfolio.holdings(); // the whole wallet, valued
await swarm.portfolio.positions(); // Hyperliquid + Binance + Polymarket + ADI
await swarm.perps.open({
  coin: "ETH",
  side: "buy",
  notionalUsd: 250,
  mode: "live",
});

Or the same thing without writing any code:

bash

swarm login --email you@example.com
swarm holdings
swarm positions
SWARM_BUDGET_USD=500 swarm market hyperliquid buy --coin ETH --notional 250 --confirm

Where to start

Writing code → SDK reference. Typing commands → CLI reference. Looking for one specific function → capabilities reference.
