Vultisig SDK

Vultisig TypeScript SDK and CLI. Create vaults, check balances, send, swap, and sign across 36+ chains. No seed phrase.

TypeScript SDK for vault create, verify, balance, send, swap, and sign. Threshold signatures. No seed phrase. 36+ chains.

Use it from a web app, a backend, Electron, or an agent. CLI (@vultisig/cli) mirrors the same surface.

Full reference: SDK docs.

Vault types

• Fast Vault — 2-of-2 with VultiServer. VultiServer co-signs and can never sign alone.

• Secure Vault — N-of-M on devices you control. Other shares join by QR from the Vultisig app.

Both vault types cover 36+ chains. The wallet picks the best swap quote (THORChain, Maya, 1inch, Kyber, LiFi, Jupiter, and others).

For AI Agents

SDK or CLI. Two trust models:

Mode	How it works	Signing	Use case
Fast Vault	Agent + VultiServer (2-of-2)	Instant, no human needed	Full agent autonomy
Secure Vault	Agent + human device (2-of-2)	Human approves via QR scan	Human oversight on every transaction

CLI for unattended agents:

npm install -g @vultisig/cli

vultisig create
vultisig balance ethereum -o json
vultisig send ethereum 0xRecipient 0.1
vultisig swap ethereum bitcoin 0.1

JSON output, silent mode, and environment variable config (VAULT_PASSWORD) plug directly into agent pipelines. Stateless usage is also supported — load a vault file, operate, discard.

For the full agent operating procedure, see vultisig.com/SKILL.md.

Getting Started

Install the SDK:

npm install @vultisig/sdk

Create a vault and start using it:

import { Vultisig } from '@vultisig/sdk'

const sdk = new Vultisig()
await sdk.initialize()

const vaultId = await sdk.createFastVault({
  name: 'My Wallet',
  email: '[email protected]',
  password: 'SecurePassword123!',
})

const vault = await sdk.verifyVault(vaultId, code)

const address = await vault.address('Ethereum')
const balance = await vault.balance('Ethereum')
