Vultisig
Vultisig is an MPC (Multi-Party Computation) wallet that enables secure crypto operations across 36+ blockchains. Unlike traditional wallets, private keys are split across multiple parties using threshold cryptography - there's no single key to steal.
Why MPC Wallets for AI Agents
Traditional wallets store a single private key or seed phrase. If compromised, all funds are lost. MPC eliminates this risk:
- No single point of failure: Keys are split across parties using cryptographic secret sharing
- Threshold security: 2-of-2 or N-of-M signing - compromising one party isn't enough
- No seed phrase exposure: No mnemonic stored in plaintext anywhere
- Automation-friendly: FastVault enables instant server-assisted signing for bots
- Programmable trust: Choose speed (FastVault) or maximum security (SecureVault)
- Audit trail: All signing requires explicit multi-party coordination
Choose Your Interface
| Use Case | Interface | Why |
|---|---|---|
| Shell scripts | CLI | Direct commands, easy scripting |
| Automation bots | CLI | Simple, pipes to jq, env vars |
| One-off operations | CLI | Quick, no code needed |
| TypeScript/Node apps | SDK | Full API, type safety |
| Custom transaction logic | SDK | signBytes, broadcastRawTx |
| Browser/React apps | SDK | Event system, async/await |
| Complex workflows | SDK | Programmatic control |
Quick Decision
Use CLI if: You're writing shell scripts, need quick commands, or want JSON output piped to other tools.
Use SDK if: You're building a TypeScript application, need programmatic control, or want event-driven updates.
Vault Types
| Type | Threshold | Signing | Best For |
|---|---|---|---|
| FastVault | 2-of-2 (device + server) | Instant (~1-2s) | AI agents, bots, automation |
| SecureVault | N-of-M (configurable) | Multi-device coordination | Teams, high-value assets |
For AI agents, FastVault is recommended - instant signing without multi-device coordination.

Get Started
CLI Quick Start
npm install -g @vultisig/cli
vultisig create fast --name "bot-wallet" --email "bot@example.com" --password "SecurePass123!"
vultisig balance -o json
SDK Quick Start
import { Vultisig, Chain } from '@vultisig/sdk'
const sdk = new Vultisig()
await sdk.initialize()
const vaultId = await sdk.createFastVault({
name: 'bot-wallet',
email: 'bot@example.com',
password: 'SecurePass123!'
})
const vault = await sdk.verifyVault(vaultId, 'email-code')
const balance = await vault.balance(Chain.Ethereum)
